This disclosure generally relates to determining a location of targets in different documents, and more particularly, to a system and method for using a local neighborhood for determining similar targets in different documents or using implicit coordinates for obtaining a coordinate location of a target.
Different types of businesses often carefully curate and extract a large volume of documents. For example, a large set of accounting documents (in the form of images and/or portable document files) are typically sent to a tax preparer, who then has the task of identifying and extracting relevant information from the accounting documents.
To provide more efficiency, businesses have tried to automate this workflow by incorporating template-based optical character recognition (OCR). Businesses have also used rigid, specific rule-based methods. For example, businesses would often perform optical character recognition to use the expected positioning of text on a document to both identify the document type and to further extract and annotate data from that document.
Templated-based OCR often includes trained humans to create each template. A human with detailed knowledge of the OCR system and document variability must review every document to specifically create sets of rules detailing exactly how to extract data from each of the documents. Templated-based OCR also usually requires trained humans to maintain each template. However, templates often degrade in performance as documents change. While some variability can be explicitly declared in the template, any unaccounted-for changes usually require humans to modify a template to account for the differences or to create a new template.
Moreover, templated-based OCR approaches typically cannot adapt to dynamic documents. In particular, some documents may be structured, but the documents have variability in table length and data positioning. While a human is often able to detect these similar regions of interest from document to document, it is extremely difficult to create generic rules/templates that are able to capture these regions and specify how to process the regions.
Furthermore, resource constraints usually exist in template creation. For an organization that may process millions of documents, the cost/benefit tradeoff required for spending the time and money to create a templated-based OCR may not be sufficient to automate the analysis of documents that appear infrequently. Instead, these documents are typically curated by hand each time the documents are encountered.
Therefore, a long-felt need exists for a way to turn such hand curation into automation via artificial intelligence approaches that do not require human interaction.
Moreover, some systems use X-Y coordinates to determine the location of certain types of values or regions of interest in a document. Traditional template-based approaches are highly dependent on absolute X-Y position, as well as overall document layout. However, the use of X-Y coordinates in a document may be unreliable because the X-Y coordinates may change among different documents. For example, if a chart (or table) is moved from a first location in a first document to a second location within a second document, the X-Y coordinate analysis may determine that the chart is a different chart because chart is now located at a different X-Y coordinate in the second document, as compared to the first document location. Similarly, if additional text (e.g., a COVID warning), chart, table or photo is added into a first document to create a second document, such additional text may shift the previous text lower down in the second document. Using the X-Y coordinates, the analysis would determine that all the text is different since the same text was shifted down the document to new X-Y coordinates. Furthermore, the X-Y coordinates may be shifted due to the document being copied such that the text is misaligned on the copied document.
A system and method are disclosed for recognizing and extracting relevant data from regions of interest between similar documents by comparing visual elements and textual elements. In various embodiments, the system may include receiving, by a processor, a new document having second content and regions of interest; comparing, by the processor, the second content of the new document to first content in one or more of a plurality of historical documents; creating, by the processor, match metrics for each of the one or more of a plurality of historical documents, wherein the match metrics are based on the comparing; verifying, by the processor, the comparing by comparing the match metrics across the plurality of historical documents; extracting, by the processor, the second content from the regions of interest in the new document; checking, by the processor, the integrity of the second content in the new document against the first content in the one or more of a plurality of historical documents; and transmitting, by the processor, the second content to a document processing system.
The comparing may be based on at least one of visual elements or textual elements. The receiving may be via at least one of an image or a PDF. The verifying may be based on statistical properties of the match of the new document compared to population statistics of the plurality of historical documents. The comparing may further comprise comparing at least one of text headers, text values, X-Y coordinate positioning or visual elements. The method may further comprise transmitting, by the processor, the new document with the second content to a human for verification, in response to the checking the integrity of the second content in the new document being a failure.
The comparing may further comprise comparing at least one of visual elements or textual elements. The comparing may further comprise comparing at least one of logos, fonts, lines or layouts. The comparing may further comprise comparing text from at least one of headers, values or tables. The comparing may be accomplished by at least one of location un-aware OCR detected text or visual document similarity indexing. The comparing may further comprise detecting, by the processor, raw text of the second content in the new document. The comparing may further comprise detecting, by the processor, tables of the second content in the new document. The comparing may further comprise pulling, by the processor, at least one of headers or text values from raw text of the second content in the new document. The comparing may further comprise pulling, by the processor, at least one of headers or text values from raw text of the second content in the new document, based on at least one of proximity or formatting. The comparing may further comprise detecting, by the processor, raw text of the first content in the historical document. The comparing may further comprise detecting, by the processor, tables of the first content in the historical document. The comparing may further comprise pulling, by the processor, at least one of headers or text values from raw text of the first content in the historical document. The comparing may further comprise pulling, by the processor, at least one of headers or text values from raw text of the first content in the historical document, based on at least one of proximity or formatting. The comparing may further comprise comparing, by the processor, visual elements between the new document and the historical document. The comparing may further comprise comparing, by the processor, visual elements between the new document and the historical document using at least one of mean square error (MSE), a structural similarity index measure (SSIM) or an image similarity metric as determined by a deep neural network.
In various embodiments, with respect to

In various embodiments, the identifying the first target and/or the identifying the one or more first elements may be accomplished using an element recognition system. The identifying the first target and/or the identifying the one or more first elements may be accomplished by finding one or more characters separated by a separator. The identifying the one or more first elements may include searching above, below, left, right and/or next to the first target. The identifying the one or more first elements may be accomplished by using non-orthogonal directions and/or using higher-order document information. The identifying the one or more first elements may be accomplished by transforming the first local neighborhood to a vector representation in a multi-dimensional space using an encoding model. The identifying the one or more first elements may be accomplished by using a type of document, wherein the type of document includes at least one of a name of the document, a company that created the document, a company that sent the document, meta-data associated with the document, a number of words in the document or if a single page document is part of a larger group of documents.

In various embodiments, with respect to
The accompanying drawings, wherein like numerals depict like elements, illustrate exemplary embodiments of the present disclosure, and together with the description, serve to explain the principles of the disclosure. In the drawings:
The system directly removes the need for human maintained and rigid OCR templates by creating a dynamic, data extraction platform based around the ability to recognize regions of interest between similar documents. In various embodiments, the system is configured to create a generalized document automation framework that captures relevant data from documents based upon replicating historical human actions associated with a document. In general, in various embodiments and with respect to
The system is document agnostic in that the system provides a fuzzy mapping between historical document extractions and new documents. For near identical documents, the system may provide perfect fidelity in extraction. For a new document that is changed from an historical document, the fidelity of the approach is entirely focused on the ability to accurately determine the mapping between extractions from the historical document and corresponding regions of interest in the new document. However, due to multiple steps of verification, if a match cannot be made, regions of interest cannot be found or extracted data is different (e.g., different in expected format or type), the system can default to human extraction. Traditional templated OCR systems include human verification for uncertain values. This system is better than templated OCR because this system can handle document types that have traditionally defied template-based OCR. For example, with the automation of property tax documents, a template-based system would require the creation and maintenance of 3000+ variations, one for each of the numerous US counties.
More specifically, in various embodiments, the system may create a database of historical documents by analyzing each of the historical documents. The historical documents may be analyzed by acquiring regions of interest (e.g., coordinates) of certain fields, logos, shapes, lines, labels or other objects, obtaining target data types and/or using known key-value pairs. In various embodiments, such factors are initially obtained in a user-driven process that results in annotated documents, as further described below. The historical documents may also be analyzed or annotated by a human user, but the human user only needs to annotate the historical document once, then the historical document can be used many times to compare to various new documents.
While other systems may try to determine the type of new document by comparing to a limited set of known document types, this system creates a database of many historical documents that are used to identify a new document. For example, each county in the U.S. may include a different property tax form, so it would be almost impossible to have a database of every type of property tax form. Thus, this system compares the new property tax form from this year to historical property tax forms in prior years that may have included the same format. For example, a taxpayer that previously submitted the prior year property tax form may live in the same county as a different taxpayer that submitted the new property tax form this year, so the system may recognize the new property tax form as matching the historical property tax form from last year. As such, the system may compare forms from the same taxpayer or from different taxpayers.
Moreover, the system goes beyond just identifying tax documents because the system identifies particular types of tax documents. For example, the system may not only recognize that an historical document is a W-2 tax document, but the system may also recognize that the historical document is a W-2 tax document from a particular employer (e.g., a Burger King W-2) and/or for a particular employee.
The system receives a new document. The new document may be in the form of an electronic document such as, for example, an image, a photo, a scan, spreadsheets (e.g., MS Excel), written documents (e.g., MS Word or emails) and/or a portable document format (PDF). The system may load the new document for comparison against an historical text corpus of the historical documents. The new documents may be processed by an automated back-end workflow. In various embodiments, an exemplary workflow may include multiple steps of autonomous functionality that ingests documents, processes documents, performs data transforms, and delivers the output. In the course of this processing, the new document is automatically sent for storage to a file system (e.g., a cloud based system) and/or may be sent to one or more systems for further processing. The new document is compared against the historical documents. Historical documents may be stored in raw text/PDF formats. However, to improve speed of computation, cached metadata about the historical document may be stored in a relational database. To optimize computation, the first time an historical document is chosen as a candidate for comparison, the extraction algorithm extracts and stores the information that is contained in the historical document such as, for example, text, key-value pairs, named entities, etc. If the historical document is used in future comparisons, the extracted information can be used directly for comparison rather than needing to repeat the extraction process each time.
The new document may be compared against a subset or all of the candidate historical documents in a corpus. For example, the system may determine a subset by selecting only the historical documents that include a certain taxpayer's name. In that regard, by reducing the set of historical documents to a subset or by not needing to include a large set of all existing types of forms, the system is able to reduce processing time and conserve processing resources. Moreover, selecting a subset of historical documents also increases the accuracy of the results because the subset includes more relevant historical documents (e.g., only documents from the same taxpayer). While the process may operate on any computer, due to the computational power needed, the process may scale to high end server/cloud computing. Additionally, in various embodiments, many of the algorithms may be accelerated further via the use of Graphics Processing Units (GPUs).
The comparing may be conducted by any process such as, for example, being based on the location un-aware OCR detected text on the new document and/or visual document similarity indexing. With respect to the location un-aware OCR detected text, the image may be pre-processed to remove scanning noise. The pre-processing may include fixing any rotation/skew that may have been applied to the document, and using high and low pass filters to remove digital noise in the brightness/contrast of the page. In comparison to traditional templated OCR approaches, the software then scans a document in search of sequences of characters in a specific language subset (e.g., English) to form words. The detected characters, words, and their exact X,Y location in the document are then extracted and stored or processed, as further described below. Alternative or in tandem to the OCR approach, the process may look at the pixel information contained in a PDF to find image elements (e.g., motifs) that can be compared, as further described below.
The system may also conduct the comparison by using identification algorithms such as, for example, machine learning, artificial intelligence, expert systems logic, key-value pair matching (e.g., matching labels next to certain data), bag-of-words and/or identifier schema (e.g., matching W-2 from a particular employer).
More specifically, with respect to machine learning, the system may use specifically supervised learning to compute the probability of two pages being similar or the same. The document may be decomposed into features, which could be any content elements, specific words, visual logos or motifs, the presence of specific fonts, absence or presence of text at different coordinates, or any other element that can be observed from the document. These features may then be used to predict an outcome such as similarity probability. A model can be trained by looking at historical pairs of documents using those features to predict the outcome.
With respect to artificial intelligence/expert systems logic, the artificial intelligence approaches (e.g., expert systems) uses a long list of IF/THEN logic based upon business rules unique to documents. For example, IF the headers of two documents match, AND there is a unique identifier on both documents, they are the same document. With respect to key/value pair matching, an initial scan is completed on the document to determine headers (keys) and corresponding values (field data). For example, on a form, there could be the word “Name:” in bold as a key, next to the value “John” in regular text. This pattern could be repeated for other keys (address, zip code, etc.) throughout the form. Recognizing this pattern, and then extracting data in this way allows for every document to be recomposed into its corresponding key/value pairs. To determine document matches, the system may compare the overlap between keys in two documents, values in two documents, or a combination.
With respect to bag of words, documents are scanned for any text. The overlap between all text extracted between two documents is then compared. With respect to identifier schema, to uniquely identify a document, a set of data points (identifiers) are defined in a data dictionary. Depending on the document type, up to five identifiers may be used to uniquely identify a document, although there is no technical limit to the number of identifiers that can be defined. An example of identifier usage would be a W-2 document that includes two identifiers: an employer ID (EIN) and an employee ID (SSN).

In various embodiments, the system may conduct non-templated machine vision comparison (e.g., visual document similarity indexing). The system may attempt to match visual elements in the new document to visual elements in a subset or all the historical documents in the corpus. For example, the logos may be similar, the layout may be similar and/or the font may be similar. The system may capture the result of these matches holistically via, for example, mean square error (MSE), a structural similarity index measure (SSIM), and/or an image similarity metric as determined by a deep neural network. Each of these algorithms may be applied to determine a match by determining a metric score for each metric. For MSE, this is obtained by going through each corresponding pixel of each image and calculating the difference between grayscale pixel intensities in each image. The system squares those differences, adds them, and divides by total number of pixels in the image. For SSIM, the system applies the method by Wang, et. al (www.cns.nyu.edu/pub/eero/wang03-reprint.pdf, which is hereby incorporated by reference). For deep learning, the system may train a decision network on known examples of matching and non-matching images to give a similarity score between any two images or may make use of “Siamese” networks or their variants. (www.proceedings.neurips.cc/paper/1993/file/288cc0ff022877bd3df94bc9360b9c5d-Paper.pdf). All of these approaches may output a score metric.
If the system finds an historical document or subset of historical documents that match the new document, in various embodiments, the automated system continues the matching process. The match may be based on a certain threshold percentage of matching items. If the system does not find a match, the system determines that a user should be consulted, so the system may notify a user or send the new document to a user. The user may then annotate the new document without using the automation features such that the system may more easily recognize the document. This is a user-interface-driven process in which the end-user identifies one or more data-points on a document and then inputs a value for each of those data points. For example, the end-user may identify an item on a document to be a property-tax payment, and then enter the amount of that payment. The user may annotate the new document by using a mouse to select and identify specific regions on the document and a keyboard to enter corresponding values, with the result being organized, labeled, tabular data extraction. This annotation process may provide the foundation and substrate for future use of the above automation process. Moreover, the system may still perform the above automated features on any additional new documents that are subsequently received by the system. As such, the system or the user may annotate or recognize regions of interest of the new document such that, in the next year, the new document is now a candidate historical document that is already annotated and can be more easily identified.

In response to matching the new document with the historical document, as set forth in
With respect to targets (e.g., text values or regions of interest), in various embodiments, a “local neighborhood” approach may be implemented. The local neighborhood process may include a target placed in context with other nearby elements. A target may be anything that appears on a document, for example, one or more words, text, numbers, characters, symbols, lines, regions, locations, figures and/or empty spaces. An element may be anything that appears on the document, for example, one or more words, text, numbers, characters, symbols, lines, regions, locations, figures and/or empty spaces. Specifically, in various embodiments and as set forth in
In various embodiments, the system may determine that that first local neighborhood in the first document and the second local neighborhood in the first document are similar to a third local neighborhood in a second document and a fourth local neighborhood in the second document. Based on the determining the similarity between the local neighborhoods in the first document and the second document, the system may determine the target in the second document that corresponds to the target in the first document.
A first local neighborhood may not be sufficient to determine a target if similar text is included more than once in a document. For example, the word “tax” may be included multiple times in a document. A first local neighborhood may identify one use of the word “tax,” but the results may be deceiving since the word “tax” may appear in other parts of the document that are not within the first local neighborhood. As such, additional local neighborhoods may help to determine the particular target among various similar targets. The method may comprise any number of local neighborhoods. For example, seven local neighborhoods may be used to help determine a target. In various embodiments, the system may assign a weight to different neighborhoods. The weighting may be larger for closer neighborhoods due to the accuracy of the elements closer to the target. The weighting may be lower for neighborhoods further from the target.
The system may find a target and/or element using any type of element recognition system or optical character recognition system. OCR software typically requires manual configuration and updates when the form changes. Thus, the system may more efficiently use an element recognition system such as, for example, the Amazon® Textract system. The element recognition system may include a machine learning (ML) service that automatically identifies and extracts any content (e.g., text, handwriting, data, forms and tables) from scanned documents. Such systems may determine a target or element based on finding one or more characters separated by a separator. A separator may include some amount of white space or vertical lines before or after a character.
In various embodiments, the system may also create more complex neighborhoods such as, for example, using non-orthogonal directions and/or based on higher-order document information (e.g., type of document, the company that created the document, metadata, etc). In addition to searching for elements directly above, below, left, right or next to the target, the system may search for elements in any direction from the target. With respect to non-orthogonal directions, each local neighborhood may be transformed to a vector representation in a multi-dimensional space using an encoding model. The local neighborhood is initially made up of a series of words. The vector method transforms a series of words to a vector of numbers. More specifically, in various embodiments, the system may create a list of unique words found in a prior year binder (e.g., corpus of documents). The prior year binder may include, for example, 2000 unique words. The vector method would transform each local neighborhood into a vector of length 2000. Each value in a vector may correspond to a single unique word and is the number of times the unique word appears in a local neighborhood.
The higher-order document information may include, for example, type of document (e.g., W-2), the company that created the document, the company that sent the document, metadata associated with the document, the number of words in the document, if a single page document is part of a larger group of documents, etc. The higher-order document information can also be transformed to a vector representation or as a feature (e.g., as an edge attribute) of a target text in a graph-based representation.
In various embodiments, the system may create a graph of the local neighborhood. The graph may include nodes and edges. For example, the target may be a first node and the word to the left of the target may be a second node. An edge may connect the nodes. The system may use the graphs of nodes and edges to search for other areas in the document represented with similar graphs. To determine a similar graph, the system may include one or more algorithms. For example, graph edit distance includes a graph similarity measure analogous to Levenshtein distance for strings where similarity is based on the number of operations needed to transform one graph into another graph.
The system may compute the similarity between any two targets. The two targets may include a first text value from the historical document and a second text value from the novel document. In various embodiments, computing the similarity may include the use of a similarity metric (e.g., cosine similarity) in the multidimensional space. Each target may be a point in the N (e.g., 2000) dimensional space. The system may create a vector from the origin (zero point) to each word. The origin may be in any dimension, so an origin in three dimensions would have 3 axes (0, 0, 0). The more similar two targets, the smaller the angle between the vectors representing the two targets. Two vectors pointing in the same direction would have an angle of 0 and a similarity score of 1 (i.e., cosine of 0 degrees is 1). The less similar two targets, the greater the angle between the vectors representing the two targets. Two vectors pointing in opposite directions would have an angle of 180 and a similarity score of −1 (i.e., cosine of 180 degrees is −1). However, the system may not want to assign a negative score, so the system may assign the score of 0 for any score that would be negative.
In various embodiments, if multiple local neighborhoods are utilized, the system may compute a global similarity value. For example, the first local neighborhood may include a cosine similarity value of 1, and the second neighborhood may include a cosine similarity value of 0.5. The system may calculate a weighted average of all neighborhoods by applying a weighting factor to each similarity value. The system may also adjust the weights of the similarity values for each local neighborhood. For example, the system may adjust the weights of the similarity values to decrease (e.g., exponentially) based on a distance from the target. For example, each outer neighborhood may be half of a previous inner neighborhood. The weights may be adjusted based on a formula, based on factors about the neighborhood and/or based on machine learning. A formula may include, for example, weightn=0.5n, where n=nth local neighborhood. This equation represents the exponential fall off with each successive local neighborhood.
In various embodiments, the system may also include an implicit coordinate technique, as a precursor to the use of local neighborhoods. If a prior year target text does not have a known X-Y location, then the implicit coordinate generation is used to identify the location of the target text. Once the target text location is identified, the above method for generating a local neighborhood may be used for that target text.
With respect to X-Y coordinates, for documents with fixed formats year-to-year, the system may use prior-year X-Y coordinates to identify the corresponding current-year target (e.g., region). If the prior year X-Y coordinates are unknown or the formats are not fixed, as set forth in
Upon discovery, the system may record the results of the target location with its corresponding X-Y location. The system, an algorithm and/or a human may obtain those X-Y coordinates from the previous document using any type of element recognition system or optical character recognition system such as, for example, Amazon Textract. The system may also obtain the location of the bounding box around the target. The location of the bounding box may include the four different coordinates corresponding to each corner of the bounding box. Such coordinates may be determined based on the pixel space. For example, the system may analyze the number of pixels from each border of the document to the target. If the same target appears multiple times, the system may use OCR to find each occurrence of the target. The system may then determine that one of the targets that is closest to the annotation box coordinates should be the desired target. If a target text does not have OCR coordinates, but the target has annotation box coordinates, the annotation box coordinates can be used by the system to identify the closest matching target text. A target may not be located at the exact X-Y coordinates that are provided, so the system may determine that the desired target is the target that is nearest to the X-Y coordinate location.
With respect to visual elements, items such as logos, lines, boxes and other geometric shapes can indicate regions of interest via proximity. With respect to key-value pairs, when the keys of key-value pairs can be matched between prior-year and current-year documents, the corresponding X-Y coordinates of the key-value pair in the prior year can determine the region of interest for the current year. The system may use the detected regions of interest in the new document to establish the new document as a new, dynamic OCR template, such that the system can extract data from the new document using the template as a guide to find the specific data. More specifically, for each comparing (or mapping) between the historical document and the new document, in the new document, the system performs OCR on the defined regions identified in the mapping. For example, if there was a mapping in the upper left of a document that found the field “Name”, and it was determined that area of interest is now in the lower right of the new document, when the field “Name” is needed in the new document, it will be extracted in the lower right but treated as equal to the historical field.
In practice, a variety of techniques may be used to extract information due to the often changing nature of documents over time. In the trivial case of simply extracting information at the same X-Y coordinates from the historical document onto the novel document, this typically works if no positional changes have occurred. However, if there is even a single line or header of text added to the novel document, then that line of text will shift all Y coordinates of the document, thus rendering a direct X-Y match ineffective. Similarly, any minor modifications to layout (e.g., moving tables or other elements, or using word wrap from a text editor causing a large value to be pushed to a following line) may alter a document enough such that direct coordinate matching is ineffective. Techniques such as key/value pair matching or local neighborhood detection may help solve these problems, as these methods are focused on locally relevant elements, apart from global positioning changes or absolute coordinates. Similarly, implicit coordinate generation is beneficial when one knows the target for extraction from an historical document, but does not know the position of the target in the novel document. Moreover, implicit coordinate generation is beneficial when that document was read in a way such that the coordinate system or even the proportion of the page is not consistent year to year. Additionally, even if the text has not moved, if the target has been modified in any way when it is extracted from the original text (e.g. rounding to nearest value), the original text and location still may need to be identified. In cases like these, since coordinates prove unreliable, understanding the context/local neighborhood of a value provides better accuracy in mapping the target to the novel document for means of extraction.
In various embodiments, the system may conduct data verification. The system may verify the extracted data by automatically identifying and comparing the entry in the new document (name, address, SSN, currency, number, etc.) to the entry extracted from the historical document. For improving the data accuracy, the system may also use accuracy algorithms such as, for example, machine learning, artificial intelligence, expert systems logic, fuzzy text matching and/or text layer extraction. These algorithms may be domain specific. For example, in accounting, one may have prior knowledge that certain numbers on a form are related (sum of a column being a total, differences being taken, etc.) and this logic can be applied to verify that extracted data is accurate. Similarly, machine learning or fuzzy logic can confirm that values are within expected ranges. For example, someone making $80,000 a year is unlikely to have $2,000,000 in stock dividends and that data should be flagged for review. In fact, the exact numbers and ranges for flagging can be found using population statistics from known forms. Text layer extraction may be a special case, where the text layer of the PDF (if it exists) is extracted to see if it is in concordance with the scanned value. For more information related to text layer extraction, see U.S. patent application Ser. No. 16/047,346, entitled “System and Method for Automatic Detection and Verification of Optical Character Recognition Data,” filed Jul. 27, 2018 and U.S. patent application Ser. No. 15/922,821 entitled “System and Method for Automatic Detection and Verification of Optical Character Recognition Data,” filed Mar. 15, 2018, the contents of which are herein incorporated by reference in their entirety for all purposes. If the system determines that the extracted data from the historical document does not match the data in the new document, the system determines that a user should be consulted. For example, the system may determine that the extracted data from the historical document does not match the data in the new document because headers do not match, entity type does not match, key known elements from the document are missing (as discovered via an expert systems/explicit check). The system may pass the extracted data to the user for verification.
In response to the system or user verifying the extracted data, in various embodiments, the system may categorize the extracted, auto-verified data in the same way in the new document as it was classified in the historical document. As mentioned above, all or any subset of data points in the system may be classified by way of a comprehensive data dictionary which describes all relevant features of any given data point. The system may run the categorized data through various processes. For example, in the context specifically of tax automation, the categorized data from the new document may be automatically processed by tax preparation software. In the realm of invoice automation, whatever actions were taken on an historical invoice (or data that was captured and transferred to other systems), can be repeated on new documents.
The system may review the new document and historical document within overlapping windows of a graphical user interface. The new document may be within a first window and the historical document with historical extractions in a second window that overlaps with the first window. The system may dynamically relocate the textual information and/or historical extractions within the first window displayed within the graphical user interface based upon a detected overlap condition. The relocation may be based upon visual elements (logos, fonts, lines, and layout), and textual elements (the text contained in headers, values, and tables on the document). When the windows overlap, textual information and/or historical extractions are reformatted and relocated to an unobscured portion of the underlying second window. The system may determine that the textual information and/or historical extractions are too large to fit in the unobstructed portion of the underlying second window. In response to being too large, the system may scale the textual information and/or historical extractions based upon a calculated scaling factor. The system may then automatically relocate the scaled textual information and/or historical extractions to the unobstructed portion of the underlying second window. When the first and second windows no longer overlap, the textual information and/or historical extractions are returned to its original format and location, and un-scaled if needed.

The present system or any part(s) or function(s) thereof may be implemented using hardware, software, or a combination thereof and may be implemented in one or more computer systems or other processing systems. However, the manipulations performed by embodiments may be referred to in terms, such as matching or selecting, which are commonly associated with mental operations performed by a human operator. No such capability of a human operator is necessary, or desirable, in most cases, in any of the operations described herein. Rather, the operations may be machine operations or any of the operations may be conducted or enhanced by artificial intelligence (AI) or machine learning. AI may refer generally to the study of agents (e.g., machines, computer-based systems, etc.) that perceive the world around them, form plans, and make decisions to achieve their goals. Foundations of AI include mathematics, logic, philosophy, probability, linguistics, neuroscience, and decision theory. Many fields fall under the umbrella of AI, such as computer vision, robotics, machine learning, and natural language processing. Useful machines for performing the various embodiments include general purpose digital computers or similar devices.
In various embodiments, the embodiments are directed toward one or more computer systems capable of carrying out the functionalities described herein. The computer system includes one or more processors. The processor is connected to a communication infrastructure (e.g., a communications bus, crossover bar, network, etc.). Various software embodiments are described in terms of this exemplary computer system. After reading this description, it will become apparent to a person skilled in the relevant art(s) how to implement various embodiments using other computer systems and/or architectures. The computer system can include a display interface that forwards graphics, text, and other data from the communication infrastructure (or from a frame buffer not shown) for display on a display unit.
The computer system also includes a main memory, such as random access memory (RAM), and may also include a secondary memory. The secondary memory may include, for example, a hard disk drive, a solid-state drive, and/or a removable storage drive. The removable storage drive reads from and/or writes to a removable storage unit in a well-known manner. As will be appreciated, the removable storage unit includes a computer usable storage medium having stored therein computer software and/or data.
In various embodiments, secondary memory may include other similar devices for allowing computer programs or other instructions to be loaded into a computer system. Such devices may include, for example, a removable storage unit and an interface. Examples of such may include a program cartridge and cartridge interface (such as that found in video game devices), a removable memory chip (such as an erasable programmable read only memory (EPROM), programmable read only memory (PROM)) and associated socket, or other removable storage units and interfaces, which allow software and data to be transferred from the removable storage unit to a computer system.
The terms “computer program medium,” “computer usable medium,” and “computer readable medium” are used to generally refer to media such as removable storage drive and a hard disk installed in hard disk drive. These computer program products provide software to a computer system.
The computer system may also include a communications interface. A communications interface allows software and data to be transferred between the computer system and external devices. Examples of such a communications interface may include a modem, a network interface (such as an Ethernet card), a communications port, etc. Software and data transferred via the communications interface are in the form of signals which may be electronic, electromagnetic, optical, or other signals capable of being received by communications interface. These signals are provided to communications interface via a communications path (e.g., channel). This channel carries signals and may be implemented using wire, cable, fiber optics, a telephone line, a cellular link, a radio frequency (RF) link, wireless and other communications channels.
As used herein an “identifier” may be any suitable identifier that uniquely identifies an item. For example, the identifier may be a globally unique identifier (“GUID”). The GUID may be an identifier created and/or implemented under the universally unique identifier standard. Moreover, the GUID may be stored as 128-bit value that can be displayed as 32 hexadecimal digits. The identifier may also include a major number, and a minor number. The major number and minor number may each be 16-bit integers.
The firewall may include any hardware and/or software suitably configured to protect CMS components and/or enterprise computing resources from users of other networks. Further, a firewall may be configured to limit or restrict access to various systems and components behind the firewall for web clients connecting through a web server. Firewall may reside in varying configurations including Stateful Inspection, ProX-Y based, access control lists, and Packet Filtering among others. Firewall may be integrated within a web server or any other CMS components or may further reside as a separate entity. A firewall may implement network address translation (“NAT”) and/or network address port translation (“NAPT”). A firewall may accommodate various tunneling protocols to facilitate secure communications, such as those used in virtual private networking. A firewall may implement a demilitarized zone (“DMZ”) to facilitate communications with a public network such as the internet. A firewall may be integrated as software within an internet server or any other application server components, reside within another computing device, or take the form of a standalone hardware component.
Any databases discussed herein may include relational, hierarchical, graphical, blockchain, object-oriented structure, and/or any other database configurations. Any database may also include a flat file structure wherein data may be stored in a single file in the form of rows and columns, with no structure for indexing and no structural relationships between records. For example, a flat file structure may include a delimited text file, a CSV (comma-separated values) file, and/or any other suitable flat file structure. Common database products that may be used to implement the databases include DB2® by IBM® (Armonk, N.Y.), various database products available from ORACLE® Corporation (Redwood Shores, Calif.), MICROSOFT ACCESS® or MICROSOFT SQL SERVER® by MICROSOFT® Corporation (Redmond, Wash.), MYSQL® by MySQL AB (Uppsala, Sweden), MONGODB®, Redis, APACHE CASSANDRA®, HBASE® by APACHE®, MapR-DB by the MAPR® corporation, or any other suitable database product. Moreover, any database may be organized in any suitable manner, for example, as data tables or lookup tables. Each record may be a single file, a series of files, a linked series of data fields, or any other data structure.
As used herein, big data may refer to partially or fully structured, semi-structured, or unstructured data sets including millions of rows and hundreds of thousands of columns. A big data set may be compiled, for example, from a history of purchase transactions over time, from web registrations, from social media, from records of charge (ROC), from summaries of charges (SOC), from internal data, or from other suitable sources. Big data sets may be compiled without descriptive metadata such as column types, counts, percentiles, or other interpretive-aid data points.
Association of certain data may be accomplished through any desired data association technique such as those known or practiced in the art. For example, the association may be accomplished either manually or automatically. Automatic association techniques may include, for example, a database search, a database merge, GREP, AGREP, SQL, using a key field in the tables to speed searches, sequential searches through all the tables and files, sorting records in the file according to a known order to simplify lookup, and/or the like. The association step may be accomplished by a database merge function, for example, using a “key field” in pre-selected databases or data sectors. Various database tuning steps are contemplated to optimize database performance. For example, frequently used files such as indexes may be placed on separate file systems to reduce In/Out (“I/O”) bottlenecks.
More particularly, a “key field” partitions the database according to the high-level class of objects defined by the key field. For example, certain types of data may be designated as a key field in a plurality of related data tables and the data tables may then be linked on the basis of the type of data in the key field. The data corresponding to the key field in each of the linked data tables is preferably the same or of the same type. However, data tables having similar, though not identical, data in the key fields may also be linked by using AGREP, for example. In accordance with one embodiment, any suitable data storage technique may be utilized to store data without a standard format. Data sets may be stored using any suitable technique, including, for example, storing individual files using an ISO/IEC 7816-4 file structure; implementing a domain whereby a dedicated file is selected that exposes one or more elementary files containing one or more data sets; using data sets stored in individual files using a hierarchical filing system; data sets stored as records in a single file (including compression, SQL accessible, hashed via one or more keys, numeric, alphabetical by first tuple, etc.); data stored as Binary Large Object (BLOB); data stored as ungrouped data elements encoded using ISO/IEC 7816-6 data elements; data stored as ungrouped data elements encoded using ISO/IEC Abstract Syntax Notation (ASN.1) as in ISO/IEC 8824 and 8825; other proprietary techniques that may include fractal compression methods, image compression methods, etc.
In various embodiments, the ability to store a wide variety of information in different formats is facilitated by storing the information as a BLOB. Thus, any binary information can be stored in a storage space associated with a data set. As discussed above, the binary information may be stored in association with the system or external to but affiliated with the system. The BLOB method may store data sets as ungrouped data elements formatted as a block of binary via a fixed memory offset using either fixed storage allocation, circular queue techniques, or best practices with respect to memory management (e.g., paged memory, least recently used, etc.). By using BLOB methods, the ability to store various data sets that have different formats facilitates the storage of data, in the database or associated with the system, by multiple and unrelated owners of the data sets. For example, a first data set which may be stored may be provided by a first party, a second data set which may be stored may be provided by an unrelated second party, and yet a third data set which may be stored may be provided by a third party unrelated to the first and second party. Each of these three exemplary data sets may contain different information that is stored using different data storage formats and/or techniques. Further, each data set may contain subsets of data that also may be distinct from other subsets.
As stated above, in various embodiments, the data can be stored without regard to a common format. However, the data set (e.g., BLOB) may be annotated in a standard manner when provided for manipulating the data in the database or system. The annotation may comprise a short header, trailer, or other appropriate indicator related to each data set that is configured to convey information useful in managing the various data sets. For example, the annotation may be called a “condition header,” “header,” “trailer,” or “status,” herein, and may comprise an indication of the status of the data set or may include an identifier correlated to a specific issuer or owner of the data. In one example, the first three bytes of each data set BLOB may be configured or configurable to indicate the status of that particular data set; e.g., LOADED, INITIALIZED, READY, BLOCKED, REMOVABLE, or DELETED. Subsequent bytes of data may be used to indicate for example, the identity of the issuer, user, transaction/membership account identifier or the like. Each of these condition annotations are further discussed herein.
The data set annotation may also be used for other types of status information as well as various other purposes. For example, the data set annotation may include security information establishing access levels. The access levels may, for example, be configured to permit only certain individuals, levels of employees, companies, or other entities to access data sets, or to permit access to specific data sets based on the transaction, merchant, issuer, user, or the like. Furthermore, the security information may restrict/permit only certain actions, such as accessing, modifying, and/or deleting data sets. In one example, the data set annotation indicates that only the data set owner or the user are permitted to delete a data set, various identified users may be permitted to access the data set for reading, and others are altogether excluded from accessing the data set. However, other access restriction parameters may also be used allowing various entities to access a data set with various permission levels as appropriate.
The data, including the header or trailer, may be received by a standalone interaction device configured to add, delete, modify, or augment the data in accordance with the header or trailer. As such, in one embodiment, the header or trailer is not stored on the transaction device along with the associated issuer-owned data, but instead the appropriate action may be taken by providing to the user, at the standalone device, the appropriate option for the action to be taken. The system may contemplate a data storage arrangement wherein the header or trailer, or header or trailer history, of the data is stored on the system, device or transaction instrument in relation to the appropriate data.
One skilled in the art will also appreciate that, for security reasons, any databases, systems, devices, servers, or other components of the system may consist of any combination thereof at a single location or at multiple locations, wherein each database or system includes any of various suitable security features, such as firewalls, access codes, encryption, decryption, compression, decompression, and/or the like.
Practitioners will also appreciate that there are a number of methods for displaying data within a browser-based document. Data may be represented as standard text or within a fixed list, scrollable list, drop-down list, editable text field, fixed text field, pop-up window, and the like. Likewise, there are a number of methods available for modifying data in a web page such as, for example, free text entry using a keyboard, selection of menu items, check boxes, option boxes, and the like.
The data may be big data that is processed by a distributed computing cluster. The distributed computing cluster may be, for example, a HADOOP® software cluster configured to process and store big data sets with some of nodes comprising a distributed storage system and some of nodes comprising a distributed processing system. In that regard, distributed computing cluster may be configured to support a HADOOP® software distributed file system (HDFS) as specified by the Apache Software Foundation at www.hadoop.apache.org/docs.
As used herein, the term “network” includes any cloud, cloud computing system, or electronic communications system or method which incorporates hardware and/or software components. Communication among the parties may be accomplished through any suitable communication channels, such as, for example, a telephone network, an extranet, an intranet, internet, point of interaction device (point of sale device, personal digital assistant (e.g., an IPHONE® device, a BLACKBERRY® device), cellular phone, kiosk, etc.), online communications, satellite communications, off-line communications, wireless communications, transponder communications, local area network (LAN), wide area network (WAN), virtual private network (VPN), networked or linked devices, keyboard, mouse, and/or any suitable communication or data input modality. Moreover, although the system is frequently described herein as being implemented with TCP/IP communications protocols, the system may also be implemented using IPX, APPLETALK® program, IP-6, NetBIOS, OSI, any tunneling protocol (e.g. IPsec, SSH, etc.), or any number of existing or future protocols. If the network is in the nature of a public network, such as the internet, it may be advantageous to presume the network to be insecure and open to eavesdroppers. Specific information related to the protocols, standards, and application software utilized in connection with the internet is generally known to those skilled in the art and, as such, need not be detailed herein.
“Cloud” or “Cloud computing” includes a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. Cloud computing may include location-independent computing, whereby shared servers provide resources, software, and data to computers and other devices on demand.
As used herein, “transmit” may include sending electronic data from one system component to another over a network connection. Additionally, as used herein, “data” may include encompassing information such as commands, queries, files, data for storage, and the like in digital or any other form.
Any database discussed herein may comprise a distributed ledger maintained by a plurality of computing devices (e.g., nodes) over a peer-to-peer network. Each computing device maintains a copy and/or partial copy of the distributed ledger and communicates with one or more other computing devices in the network to validate and write data to the distributed ledger. The distributed ledger may use features and functionality of blockchain technology, including, for example, consensus-based validation, immutability, and cryptographically chained blocks of data. The blockchain may comprise a ledger of interconnected blocks containing data. The blockchain may provide enhanced security because each block may hold individual transactions and the results of any blockchain executables. Each block may link to the previous block and may include a timestamp. Blocks may be linked because each block may include the hash of the prior block in the blockchain. The linked blocks form a chain, with only one successor block allowed to link to one other predecessor block for a single chain. Forks may be possible where divergent chains are established from a previously uniform blockchain, though typically only one of the divergent chains will be maintained as the consensus chain. In various embodiments, the blockchain may implement smart contracts that enforce data workflows in a decentralized manner. The system may also include applications deployed on user devices such as, for example, computers, tablets, smartphones, Internet of Things devices (“IoT” devices), etc. The applications may communicate with the blockchain (e.g., directly or via a blockchain node) to transmit and retrieve data. In various embodiments, a governing organization or consortium may control access to data stored on the blockchain. Registration with the managing organization(s) may enable participation in the blockchain network.
Data transfers performed through the blockchain-based system may propagate to the connected peers within the blockchain network within a duration that may be determined by the block creation time of the specific blockchain technology implemented. For example, on an ETHEREUM®-based network, a new data entry may become available within about 13-20 seconds as of the writing. On a HYPERLEDGER® Fabric 1.0 based platform, the duration is driven by the specific consensus algorithm that is chosen, and may be performed within seconds. In that respect, propagation times in the system may be improved compared to existing systems, and implementation costs and time to market may also be drastically reduced. The system also offers increased security at least partially due to the immutable nature of data that is stored in the blockchain, reducing the probability of tampering with various data inputs and outputs. Moreover, the system may also offer increased security of data by performing cryptographic processes on the data prior to storing the data on the blockchain. Therefore, by transmitting, storing, and accessing data using the system described herein, the security of the data is improved, which decreases the risk of the computer or network from being compromised.
In various embodiments, the system may also reduce database synchronization errors by providing a common data structure, thus at least partially improving the integrity of stored data. The system also offers increased reliability and fault tolerance over traditional databases (e.g., relational databases, distributed databases, etc.) as each node operates with a full copy of the stored data, thus at least partially reducing downtime due to localized network outages and hardware failures. The system may also increase the reliability of data transfers in a network environment having reliable and unreliable peers, as each node broadcasts messages to all connected peers, and, as each block comprises a link to a previous block, a node may quickly detect a missing block and propagate a request for the missing block to the other nodes in the blockchain network.
The particular blockchain implementation described herein provides improvements over conventional technology by using a decentralized database and improved processing environments. In particular, the blockchain implementation improves computer performance by, for example, leveraging decentralized resources (e.g., lower latency). The distributed computational resources improves computer performance by, for example, reducing processing times. Furthermore, the distributed computational resources improves computer performance by improving security using, for example, cryptographic protocols.
