The present invention generally relates to programmable computing systems, and more specifically, to enhanced section detection using a combination of object detection with heuristics.
Information retrieval computing systems can receive search queries from a user and provide answers back to the user. In information retrieval, a question answering (QA) system is tasked with automatically answering a question posed in natural language to the system. A QA system can retrieve an answer by searching a data corpus for documents matching the search query. To assist the QA system, the documents are annotated to describe relationships between co-existing entities. The process of annotating documents is performed by subject matter experts who review the documents and determine whether any entities in the documents can be annotated. The annotations assist the QA system to retrieve the best documents to answer the search query.
According to a non-limiting embodiment, a computer system includes a natural language processing (NLP) unit, a storage unit, a user interface and a search engine. The NLP unit analyzes a content source to identify one or more sections containing searchable content and generate section metadata respective to each identified section included in the content source. The storage unit stores the section metadata and the user interface receives a section-scoped query aimed at searching an identified section corresponding to the at least one first section metadata stored in the storage unit without searching an identified section corresponding to at least one second section metadata stored in the storage unit. Based on the section-scoped query, the search engine analyzes the at least one first section metadata stored in the storage unit without analyzing the at least one second section metadata.
According to another non-limiting embodiment, a computer-implemented method is provided to selectively target content sections of raw data included in a raw content source. The method comprises analyzing, via a natural language processing (NLP) unit, at least one content source to identify a plurality of sections containing searchable content; and generating, via the NLP unit, section metadata respective to each identified section included in the at least one content source. The method further comprises storing the section metadata in a storage unit; and receiving, via a user interface, a section-scoped query. The section-scoped query is configured to search an identified section corresponding to the at least one first section metadata stored in the storage unit without searching an identified section corresponding to at least one second section metadata stored in the storage unit. Based on the section-scoped query, analyzing via a search engine, the at least one first section metadata stored in the storage unit without analyzing the at least one second section metadata.
A computer program product to control a computer system to selectively target content sections of raw data included in a raw content source, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by an electronic computer processor to control the computer system to perform operations comprising analyzing, via a natural language processing (NLP) unit, at least one content source to identify a plurality of sections containing searchable content; and generating, via the NLP unit, section metadata respective to each identified section included in the at least one content source. The operations further comprise storing the section metadata in a storage unit; and receiving, via a user interface, a section-scoped query. The section-scoped query is configured to search an identified section corresponding to the at least one first section metadata stored in the storage unit without searching an identified section corresponding to at least one second section metadata stored in the storage unit. Based on the section-scoped query, analyzing via a search engine, the at least one first section metadata stored in the storage unit without analyzing the at least one second section metadata.
Other embodiments of the present invention implement features of the above-described method in computer systems and computer program products.
Additional technical features and benefits are realized through the techniques of the present invention. Embodiments and aspects of the invention are described in detail herein and are considered a part of the claimed subject matter. For a better understanding, refer to the detailed description and to the drawings.
The specifics of the exclusive rights described herein are particularly pointed out and distinctly claimed in the claims at the conclusion of the specification. The foregoing and other features and advantages of the embodiments of the invention are apparent from the following detailed description taken in conjunction with the accompanying drawings in which:
The diagrams depicted herein are illustrative. There can be many variations to the diagrams or the operations described therein without departing from the spirit of the invention. For instance, the actions can be performed in a differing order or actions can be added, deleted or modified. Also, the term “coupled” and variations thereof describes having a communications path between two elements and does not imply a direct connection between the elements with no intervening elements/connections between them. All of these variations are considered a part of the specification.
One or more embodiments of the present invention provide computer-implemented methods and computing systems that receive a scanned image of an original text document and convert the image into machine-encodable text that has a same layout as the original text document.
Computer information retrieval systems are operable to receive a search query and, in response, analyze data included in a content source such as an electronic document, for example, to retrieve an answer to the query. Conventional computer information retrieval systems typically operate by performing character recognition (e.g., optical character recognition (OCR)) of the raw data included in the content source. In this manner, the information retrieval system can distinguish topic headings from the body of text associate with a given topic heading, and in turn identify particular sections of included in the content source.
Searching and reviewing literature content can prove to be challenging and cumbersome. Literature in particular may include a collection of non-normalized random documents that pose challenges for reviewers to find relevant content for an area of investigation without reading the entire document. In addition, a user may be required to access multiple search engines (ClinicalTrials.gov, PubMed, Embase), each which is uniquely designed to search a particular genre or technical field. While documents typically have similarly named headings and sections, there are instances where one or more documents have unique named sections or heading, or use a different approach to distinguish individual section within a document. For example, the layout and design of a first document may be completely different from the layout and design of a different second document. Thus, one document very likely contains titles, headings, sub-headings and section layouts that are different from another different document. Therefore, a user that is searching for various topics or information among a multitude of different document types is practically unaware of the different headings and sections contained in all the documents to be analyzed. Furthermore, reviewers are unable to rely on a table of contents or similar navigation aid to determine whether a document potentially contains content relevant to the reviewer's query. For example, research articles may have sections like introduction, discussion, materials and methods, and results while others have proposal, background, rational, techniques, and outcomes. The capability to search all articles for relevancy becomes problematic without using a general text search or full content analytic search which typically returns more content and results than the reviewer can reasonably process efficiently.
One or more embodiments of the present invention addresses one or more of the above-described shortcomings by providing a cognitive analytics and search system configured to selectively target content sections of raw data included in a raw content source. The cognitive analytics and search system allows users (e.g., researches, data reviewers, literature investigators, etc.) to define commonly identified sections that can be separately cognitively analyzed. Accordingly, users can focus their efforts on explicit sections of documents making the discovery of relevant content more efficient. The cognitive analytics and search system also provides normalized enriched document sections within a content source, thereby allowing a single corpus to be of value to multiple user groups.

The object domain unit 101 includes a conversion unit 102, a machine learning unit 104, and a formatting unit 106. In one or more non-limiting embodiments, one or more of the conversion unit 102, the machine learning unit 104, and the formatting unit 106 are constructed as an individual electronic hardware controller that includes memory and a processor configured to execute algorithms and computer-readable program instructions stored in the memory.
The conversion unit 102 is configured to receive a content source including data such as, for example, text and objects, and convert any text found in the content source into a machine-encodable data. The machine learning unit 104 is trained to detect the objects in the content source. The objects include sections (e.g., blocks of text, paragraphs, bullet points) found in the content source. The formatting unit 106 is configured to embed the machine-encodable text file with metadata that describes the layout of the detected objects.
In one or more non-limiting embodiments, the conversion unit 102 is operable to receive one or more electronic document images 108 as the content source and convert the text found in a document image 108 to machine-encodable information, such as, for example, plain text, a URL, a product code, etc. The document image 108 can be generated from an original document. The original document can include, but is not limited to, a paper document, a document generated by word processing software, a healthcare journal article, a patient's medical file, doctor's notes, or other types of literature. Because the content source can include various types of documents, the layout and design (e.g., titles, headings, sub-headings and section layouts) are completely different among the documents input to the conversion unit 102.
In terms of paper documents, a document image 108 can be a scanned image of a paper document, a portable document format (PDF) file, an image captured by an image capturing device, or other form of document image. The image file can be converted to any appropriate image format. In some embodiments, the image format is selected based on a type of machine learning unit used to analyze the image file Accordingly, the conversion unit 102 can use optical character recognition (OCR), for example, to convert the text found in a document image 108 to the machine-encodable information.
The conversion unit 102 can also receive the document image 108 or a bitmap describing the image and identify dark and light areas. The conversion unit 102 can further analyze the dark areas for the presence of alphanumeric characters (text). The conversion unit 102 can apply various methods to determine if the dark area contains any text. For example, the conversion unit 102 can use pattern recognition, in which the conversion unit 102 can compare and recognize the shapes formed by the dark areas with example alphanumeric characters in different fonts and font sizes. The conversion unit 102 can also apply feature detection, in which the conversion unit 102 can be trained to recognize different features such as a number of curves or arrangement or curved and straight lines. For example, the letter “P” can be a combination of a straight line and an arc at one end of the straight line. Once an alphanumeric character is recognized, it can be converted to an encoding standard such as the American Standard Code for Information (ASCII) or other appropriate encoding standard based upon language and geographic location. A computing system can read the ASCII code for the alphanumeric character and generate the corresponding letter or number. Once the conversion unit 102 has identified each alphanumeric character in the image, it can convert the text from the image into machine-encodable text, such as a plain text or a rich text format.
The machine learning unit 104 can further extract features and analyze the features to determine the boundaries of different sections in the document image 108. In some embodiments of the present invention, the machine learning unit can include a convolutional neural network-based classifier. For example, the machine learning unit 104 can use a Regional Convolutional Neural Network (R-CNN). The R-CNN can receive document image 108 and detect objects contained therein. The objects include different sections of the document, including but not limited to paragraphs of text, figures, bullet points, titles, conclusions, and other natural sections of a document. In some embodiments of the present invention, the R-CNN first generates bounding boxes in document image 108 to find candidate sections and runs a classifier on each bounding box. The R-CNN further determines a location and dimension of each bounding box. The R-CNN analyzes the extracted features to determine whether a bounding box encapsulates one or more sections. The R-CNN can be trained to detect features that suggest distinct text blocks. The features can include offsets between text blocks, underlined or bolded words at the beginning of a text block, spacing, punctuation, capitalized strings of text, graphical indicator (e.g., box surrounding text), formatting (e.g., bolding, underlining), or other appropriate features. Upon classification of different objects, the R-CNN removes duplicate classifications and scores the boxes based on the other detected objects in the image. The highest scoring bounding boxes are classified as sections. The objects can take the form of geometric shapes that distinguish the different sections of the original document.
It should be appreciated that a classification type of object is not necessary for object detection. In some embodiments of the present invention, the machine learning unit 104 does recognize the alphanumeric characters at the beginning and end of the section encapsulated by a box. In other embodiments, each alphanumeric character in an image can be indexed, and the machine learning unit 104 recognizes and index number of the beginning and ending character of each text block. However, the machine learning unit 104 does not need to recognize the substance of each text block. In other words, the machine learning unit 104 does not need to describe the purpose or subject matter of an object. The purpose of subject matter can include but not be limited to a title block, patient medical history, diagnosis, or conclusion. Rather, the machine learning unit 104 detects the beginning and ending of distinct sections without deriving meaning from the sections.
The phrases “neural network” and “machine learning” broadly describes a function of electronic systems that learn from data. A machine learning system, engine, unit, or module can include a machine learning algorithm that can be trained, such as in an external cloud environment (e.g., the cloud computing environment 50), to learn functional relationships between inputs and outputs that are currently unknown. In one or more embodiments, machine learning functionality can be implemented using a machine learning unit 104, having the capability to be trained to perform a currently unknown function. In machine learning and cognitive science, neural networks are a family of statistical learning models inspired by the biological neural networks of animals, and in particular, the brain. Neural networks can be used to estimate or approximate systems and functions that depend on a large number of inputs.
The machine learning unit 104 can be embodied as so-called “neuromorphic” systems of interconnected processor elements that act as simulated “neurons” and exchange “messages” between each other in the form of electronic signals. Similar to the so-called “plasticity” of synaptic neurotransmitter connections that carry messages between biological neurons, the connections in the machine learning unit 104 that carry electronic messages between simulated neurons are provided with numeric weights that correspond to the strength or weakness of a given connection. During training, the weights can be adjusted and tuned based on experience, making the machine learning unit 104 adaptive to inputs and capable of learning. After being weighted and transformed by a function determined by the network's designer, the activation of these input neurons is then passed to other downstream neurons, which are often referred to as “hidden” neurons. This process is repeated until an output neuron is activated. The activated output neuron determines which character was read.
The formatting unit 106 is operable to map the objects detected by the machine learning unit 104 back on to the machine-encodable text generated by the conversion unit 102. The formatting unit 106 receives data describing each object from the machine learning unit 104 and encodes the machine-encodable text with metadata describing each object. The metadata respectively describes the boundaries and location of each section. The boundaries and location can be in relation to each other sections, a perimeter of the original document, or both. The formatting unit 106 reformats the machine-encodable text such that the layout of the sections conforms to the layout of the sections in the document image 108. The formatting unit 106 detects the beginning alphanumeric character and the ending alphanumeric character of a text block in a section. The formatting unit 106 arranges the location of the sections. This results in the machine-encodable text having the same layout as arranged in the document image 108.
The user interface 120 includes a display unit 122, a section designation unit 124, and a section-scoped query unit 126. In one or more non-limiting embodiments, one or both of the section designation unit 124 and the section-scoped query unit 126 are constructed as individual electronic hardware controllers that include memory and a processor configured to execute algorithms and computer-readable program instructions stored in the memory.
The section designation unit 124 allows a user to designate one or more readable sections included in the content source 108 (e.g., one or more document images 108) received by the object domain unit 101. In one or more non-limiting embodiments, the section designation unit 124 prompts the user, via the display unit 122, to designate one or more desired sections to be searched within the content source 108. The input designated sections are then delivered to the NLP unit 110 where they are analyzed to generate artifacts corresponding to a given section. The section designation unit 124 receives a controls (e.g., based on an input from a user) indicative different identified sections (i.e., as identified from the user) from multiple document images that when analyzed by the NLP unit 110 all generated artifacts are stored within a common given section name for all document images.
More specifically, the NLP unit 110 receives the reformatted machine-encodable text generated by the object domain unit 101. The NLP unit 110 is configured to apply natural language processing techniques to semantically analyze the text, including determining entities to describe the text, and relationships between textual phrases. In one or more non-limiting embodiments, the NLP unit 110 analyzes the readable sections designated by the user and extracts data content therefrom to generate one or more artifacts. The artifacts include, but are not limited to, fields, concepts, attributes, entities, relations, etc.). The generated artifacts for a given section are then stored in an artifact storage unit 112. In one or more non-limiting embodiments, the NLP unit 110 also generates metadata that indexes one or more given artifacts to a corresponding section. In this manner, the artifacts stored in the artifact storage unit 112 can be searched by the search engine 130 on a per-section basis.
The user interface 120 is granted access to the artifact storage unit 112. In one or more embodiments, the searchable sections corresponding to the artifacts stored in the artifact storage unit 112 are displayed on a display unit 122. Accordingly, the user may view the sections that can be searched on a per-section basis. In one or more embodiments, the section-scoped query unit 126 included in the user interface 120 prompts the user, via the display unit 122, to define a section-scoped query to be performed on one or more of the sections corresponding to the artifacts stored in the artifact storage unit 112. The section-scoped query is aimed at searching an identified section corresponding to the at least one first section metadata stored in the storage unit without searching an identified section corresponding to at least one second section metadata stored in the storage unit. In this manner, a user-defined section-scope query can be designated and performed by the search engine 130 as described in greater detail below.
The search engine receives the user-defined section-scope query, and in response searches the artifact storage unit 112. In one or more embodiments, the search includes analyzing the artifacts corresponding to a respective section indicated by the user's section-scoped query. Accordingly, the search engine 130 returns the artifacts and content (e.g. textual data) from the sections that match the user's section-scoped query. That is, based on the section-scoped query, the search engine 130 analyzes targeted section metadata (i.e., identified by the user) stored in the storage unit without analyzing non-targeted section metadata. In this manner, a user-defined section-scoped query can be performed, which allows users to focus their efforts on explicit targeted sections of documents making the discovery of relevant content more efficient.

As shown in
Alternatively, the section designation unit 124 can allow the user to identify identical or differing sections from multiple document sources and specify a common section name and combining multiple sections from document sources as a single section such that when the NLP unit 110 analyzes the content artifacts are persisted in storage unit 112 and can be displayed to a user via the display unit 122. As shown in

In some instances, the machine learning unit 104 can determine that information is confidential and should not be transmitted. The machine learning unit 104 can be trained to determine certain documents can contain confidential information such as a patient's identity, security number, contact information, or other confidential information. For example, the machine learning unit 104 can be trained to detect a document potentially contains confidential information based on keywords, a document source, embedded metadata indicating the confidentiality of certain information, or other document feature. In these instances, the formatting unit 106 can replace the confidential information with a generic character such as a “#”, mask the confidential information, or otherwise obfuscate the confidential information. In these instances, the formatting unit 106 can continue to reformat machine-encodable text as if the confidential information were present. Therefore, the layout of the machine encodable text appears the same as in the document image 200, but without the confidential information being readable.

The method begins at operation 600, and at operation 602 content source including one or more detectable objects is input to the object domain unit 101. The content source can include, for example, and electronic document (e.g., document image) converted from an original document containing one or more objects such as, for example, sections of readable text. At operation 604, a user designates, via a user interface 120, one or more readable sections, which are received by the object domain unit 101. As described herein, the user interface 120 includes a section designation unit 124, which prompts a user to designate one or more desired sections to be searched within the content source. The input designated sections are then delivered to an NLP unit 110 to be analyzed as described in greater detail below. The analyzed sections become the searchable sections within a searched artifact storage unit 112 as described in greater detail below.
At operation 606, each designated readable section is delivered to the NLP unit 110. The NLP unit 110 analyzes the readable sections and generates one or more artifacts. The artifacts include, but are not limited to, concepts, attributes, entities, relations, etc.). The generated artifacts for a given section are then stored in the artifact storage unit 112. As mentioned herein, at operation 606 the NLP unit 110 can also generate metadata that indexes one or more given artifacts to a corresponding section. The artifacts and metadata (e.g., section headings) are stored at operation 608. In this manner, the artifacts stored in the artifact storage unit 112 can be searched on a per-section basis.
Turning to operation 610, the user interface 120 is allowed access to the artifact storage unit 112. In one or more embodiments, the searchable sections corresponding to the artifacts stored in the artifact storage unit 112 are displayed on a display unit 122 included with the user interface 120. At operation 612, the user submits, via the user interface 120, a section-scoped query which is received by the search engine 130. As described herein, the section-scoped query unit 126 prompts the user to define the section-scoped query to be performed on one or more of the sections corresponding to the artifacts stored in the artifact storage unit 112. For example, the user can operate the user-interface 120 to input one or more query terms and to select one or more displayed sections to be searched within the artifact storage unit 112. Sections that are not selected by the user are thus not searched within the storage unit 112.
Turning to operation 614, the search engine 130 searches the artifact storage unit 112 and analyzes the artifacts corresponding to a respective section indicated by the user's section-scoped query. Accordingly, the search engine 130 returns results including, for example, artifacts and content (e.g. textual data), from the sections that match the user's section-scoped query input at operation 616, and the method ends at operation 618.
With reference to
For example, the method begins at operation 650 and at operation 652 one or more content sources including one or more detectable objects are input to the object domain unit 101. At operation 654, the NLP unit 110 analyzes the readable sections and generates one or more artifacts corresponding to a respective readable section. The artifacts include, but are not limited to, concepts, attributes, entities, relations, etc.). At operation 654, the NLP unit 110 can also generate metadata that indexes one or more given artifacts to a respective section. The artifacts and metadata (e.g., section headings) are then stored in an artifact storage unit 112 at operation 656. In this manner, the artifacts stored in the artifact storage unit 112 can be searched on a per-section basis.
Turning to operation 658, the user interface 120 is allowed access to the artifact storage unit 112. In one or more non-limiting embodiments, the searchable sections corresponding to the artifacts stored in the artifact storage unit 112 are displayed on a display unit 122 included with the user interface 120. At operation 660, the user submits, via the user interface 120, a section-scoped query which is received by the search engine 130. As described herein, the section-scoped query unit 126 prompts the user to define the section-scoped query to be performed on one or more of the sections corresponding to the artifacts stored in the artifact storage unit 112. For example, the user can operate the user-interface 120 to input one or more query terms and to select one or more displayed sections to be searched within the artifact storage unit 112. Sections that are not selected by the user are thus not searched within the storage unit 112. Turning to operation 662, the search engine 130 searches the artifact storage unit 112 and analyzes the artifacts corresponding to a respective section indicated by the user's section-scoped query. At operation 664, the search engine 130 returns results including, for example, artifacts and content (e.g. textual data), from the sections that match the user's section-scoped query input, and the method ends at operation 666.
It is to be understood that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed.
Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.
Characteristics are as follows:
On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.
Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).
Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).
Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.
Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service.
Service Models are as follows:
Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based e-mail). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.
Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.
Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).
Deployment Models are as follows:
Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.
Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.
Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.
Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds).
A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure that includes a network of interconnected nodes.

Further depicted are an input/output (I/O) adapter 727 and a network adapter 726 coupled to the system bus 733. I/O adapter 727 may be a small computer system interface (SCSI) adapter that communicates with a hard disk 723 and/or a storage device 725 or any other similar component.
