The storage system manager 312 may communicate with the storage media 304, 308 on the higher storage tier(s) 302 and lower storage tier(s) 306 through a network 310, such as a storage area network (SAN), as shown in
In more embodiments, the storage system 300 may include any number of data storage tiers, and may include the same or different storage memory media within each storage tier. For example, each data storage tier may include the same type of storage memory media, such as HDDs, SSDs, sequential access media (tape in tape drives, optical disk in optical disk drives, etc.), direct access media (CD-ROM, DVD-ROM, etc.), or any combination of media storage types. In one such configuration, a higher storage tier 302, may include a majority of SSD storage media for storing data in a higher performing storage environment, and remaining storage tiers, including lower storage tier 306 and additional storage tiers 316 may include any combination of SSDs, HDDs, tape drives, etc., for storing data in a lower performing storage environment. In this way, more frequently accessed data, data having a higher priority, data needing to be accessed more quickly, etc., may be stored to the higher storage tier 302, while data not having one of these attributes may be stored to the additional storage tiers 316, including lower storage tier 306. Of course, one of skill in the art, upon reading the present descriptions, may devise many other combinations of storage media types to implement into different storage schemes, according to the embodiments presented herein.

Of course, this logic may be implemented as a method on any device and/or system or as a computer program product, according to various embodiments.
Now referring to
Each of the steps of the method 400 may be performed by any suitable component of the operating environment. For example, in various embodiments, the method 400 may be partially or entirely performed by one or more servers, computers, or some other device having one or more processors therein. The processor, e.g., processing circuit(s), chip(s), and/or module(s) implemented in hardware and/or software, and preferably having at least one hardware component may be utilized in any device to perform one or more steps of the method 400. Illustrative processors include, but are not limited to, a central processing unit (CPU), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), etc., combinations thereof, or any other suitable computing device known in the art.
As shown in
Additionally, in one embodiment, one or more of the plurality of documents may include scanned content. For example, one or more of the plurality of documents may include all or a portion of a scanned document. In another example, optical character recognition may be performed on the scanned document in order to extract and obtain the textual data from the scanned document. In another embodiment, the textual data may include alphanumerical data. For example, the textual data may include one or more words, sentences, paragraphs, numbers, tables, etc.
Further, in one embodiment, the predetermined subject may include one or more terms that identify common subject matter shared by each of the plurality of documents. For example, the predetermined subject may include one or more general descriptive terms that identify subject matter shared by each of the plurality of documents.
In another embodiment, the plurality of documents may be included within a predetermined grouping. For example, the plurality of documents may be included within a slash tag, where the slash tag groups identifiers of a location of each of the plurality of documents (e.g., hyperlinks, pointers, etc.) within a centralized location. In another example, the slash tag may also include identifiers of one or more of the plurality of documents themselves. In yet another embodiment, the slash tag may include a database, a table, a textual document, or any other data structure or document grouping the plurality of documents. In still another embodiment, the slash tag may be unique to the predetermined subject.
Further still, as shown in
Also, in one embodiment, analyzing the textual data for each of the plurality of documents may include refining the textual data by removing one or more words from the textual data. For example, the textual data may be stripped of one or more words having a predetermined frequency and a predetermined significance. In another example, one or more predetermined words (e.g., “common” words, plural or verb conjugation endings, etc.) may be removed from the textual data to create the refined textual data.
In addition, in one embodiment, analyzing the textual data for each of the plurality of documents may include refining the textual data by removing any duplicate documents within the plurality of documents. For example, textual data that is determined to be duplicated within the plurality of documents may be removed so that only a single instance of such textual data is included in the refined textual data.
Furthermore, in one embodiment, analyzing the textual data for each of the plurality of documents may include performing a latent dirichlet allocation (LDA) analysis on the refined textual data to identify the one or more categories. For example, performing the LDA analysis on the refined textual data may include transforming the refined textual data into an array (e.g., a bag-of-words array, etc.) and determining the one or more categories from the array.
Further still, in one embodiment, the one or more categories may each include one or more topic vectors, where each topic vector includes one or more identified keywords within the refined textual data as well as a frequency of the one or more keywords within the refined textual data. In another embodiment, the topic vectors may be analyzed to identify textual data that is included in a number of topic vectors that is below a threshold level. In yet another embodiment, topic vectors that include the identified textual data may be removed from the identified topic vectors.
In another embodiment, analyzing the textual data for each of the plurality of documents may include performing any other type of analysis. For example, analyzing the textual data may include performing one or more of natural language subject, object, and predicate extraction.
Also, as shown in
Additionally, in one embodiment, the one or more categories may be used to perform classification of additional textual data. For example, additional textual data (e.g., scanned and OCR'd data, web page textual content, etc.) may be compared to the one or more categories to generate a probability that the unprocessed textual data is associated with the predetermined subject linked to the one or more categories. In this way, the one or more categories identified within the plurality of the documents may be used to classify unprocessed textual data.
Now referring to
Each of the steps of the method 500 may be performed by any suitable component of the operating environment. For example, in various embodiments, the method 500 may be partially or entirely performed by one or more servers, computers, or some other device having one or more processors therein. The processor, e.g., processing circuit(s), chip(s), and/or module(s) implemented in hardware and/or software, and preferably having at least one hardware component may be utilized in any device to perform one or more steps of the method 500. Illustrative processors include, but are not limited to, a central processing unit (CPU), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), etc., combinations thereof, or any other suitable computing device known in the art.
As shown in
Additionally, in one embodiment, the predetermined subject may include a slash tag, and the plurality of documents may be gathered in association with the slash tag. In another embodiment, slash tags may include test tags, admin tags, tags created for certain business partners for specific uses, group tags for managing other tags, etc. In yet another embodiment, one or more document sets may be built for each of these slash tags through any of various ways, including using expert librarians to determine websites of high quality on each slash tag subject.
Further, in one embodiment, identified pages may have supplementary information like user lists on a web forum, or mailing addresses, or legal agreements. In another embodiment, a predetermined portion of the data in a slash tag's document set may be about the underlying subject. In this way, getting the most probable sets of topics is diagnostic of a subject, even if not all the training data is pure. In yet another embodiment, separate text extraction jobs for each of these slash tags may run over the nosql database, to extract text for each given subject.
Further still, method 500 may proceed with operation 504, where text identified within the plurality of documents is processed. For example, once the raw extracted text is gathered, it may then be processed for analysis. In one embodiment, as part of the gathering of text, before saving it to local disk, automatic language detection may be performed. For example, this may be performed using one or more methodologies. For instance, an open source chromium compact language detection library (CLD) may be utilized to determine the language of the text.
Also, in one embodiment, only documents written in a predetermined language (e.g., English-text documents, etc.) may be saved. In another embodiment, processing the text may include stripping the text of all words that have no significance in classifying the text. Such words may be referred to as stop words, which, for example, may be words found at a high frequency such as, “a” and “the.” If left in, the LDA analysis may have these words as strong in all topic vectors produced, which would mean that the words may have no significance in classifying the text.
In addition, in one embodiment, because certain aspects may be used to develop an automatic way to determine words that are diagnostic of a subject, small common words that form the grammar of the language may not be diagnostic of any particular subject. Thus, in another embodiment, these stop words may be stripped from the text to increase the significance of the remaining words for classification.
Furthermore, in one embodiment, processing the text may include stemming one or more words within the text by removing plural or verb conjugation endings. For example, words with separate ends may be analyzed with the same significance. This may be performed using a Lingua::Stem::En module for perl for example. In another embodiment, processing the text may include checking all documents within each subject to remove duplicate documents so the system saves only unique documents. In another embodiment, the order of these documents may then be randomized, and the set may be divided into training and test data with an 80/20 split, for example.
Further, method 500 may proceed with operation 506, where a latent dirichlet allocation (LDA) analysis is performed on the processed text to identify a plurality of topic vectors indicative of the predetermined subject. In one embodiment, the processed text may include the gathered documents from the curated slash tag. In this way, the documents may be used to provide a distinct corpus for the predetermined subject covered by the slash tag. In another embodiment, each this distinct corpus may be analyzed to determine one or more topic vectors within the corpus using LDA analysis.
Further still, in one embodiment, a number of topic vectors may be based on a number of documents associated with the processed text. For example, a number of topic vectors to use for analysis may be equal to the square root of half of the number of documents. In another embodiment, the LDA analysis may be performed using a Gensim library for python.
Also, in one embodiment, performing the LDA analysis may include reading in and splitting up documents into text words, where only words that existed in two or more documents may be analyzed. In another embodiment, performing the LDA analysis may include producing a dictionary of these words, which may provide a unique integer for each word. In another embodiment, performing the LDA analysis may include converting the one or more documents into a bag-of-words array, where only the word, represented as an integer, and the number of times it was used is saved. These bag-of-word arrays may then be analyzed using LDA to find the resulting topic vectors.
Additionally, in one embodiment, the LDA analysis may be performed separately for each subject, correlating to the number of slash tags utilized in the example. In another embodiment, the production may be managed on computer clusters. In yet another embodiment, each example job may produce a set of unit topic vectors, with words (as integers) and frequencies.
Further, in one embodiment, to reduce an effect of spam, the topic vectors may be analyzed, such that if one topic vector is determined to use words that are rarely used in other topic vectors, then it is labeled as a bad topic label. In another embodiment, documents containing a predetermined number of words included within vectors having a bad topic label may be removed from the corpus of documents. The LDA analysis may then be repeated, without these removed documents.
Further still, in one embodiment, the data, slash tags and information may be updated and refined. For example, the predetermined subject may be removed if a number of topic vectors identified therein are below a threshold value and/or if usage of the predetermined subject is below a threshold. In another embodiment, the processing and analysis of document text may be repeated periodically as the data set changes.
Now referring to
Each of the steps of the method 600 may be performed by any suitable component of the operating environment. For example, in various embodiments, the method 600 may be partially or entirely performed by one or more servers, computers, or some other device having one or more processors therein. The processor, e.g., processing circuit(s), chip(s), and/or module(s) implemented in hardware and/or software, and preferably having at least one hardware component may be utilized in any device to perform one or more steps of the method 600. Illustrative processors include, but are not limited to, a central processing unit (CPU), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), etc., combinations thereof, or any other suitable computing device known in the art.
As shown in
Additionally, in one embodiment, the topic vectors may be limited to only words that have a certain strength, for example, of more than 0. 01. Any words with a strength less than the predetermined strength in a topic vector may be ignored. A dictionary may be produced with all words from all topic vectors of all subjects, and saved, to provide a unique mapping of words used to integers.
Further, in one embodiment, any unclassified text may be processed in the same way as the text was analyzed, with the removal of stop words and stemming. Then the words may be turned into integers using the dictionary, any words not in the dictionary may be ignored. In certain examples, the unclassified text may then be turned into a bag-of-words, including integers and the number of times the integers occur in a given document. This bag of words may then be turned into a unit vector, where all the occurrences are normalized to the overall length.
Further still, in one embodiment, the unit vector may be compared to all the produced topic vectors by taking the dot product of the two, where the dot product is an algebraic operation that takes two numbers of equal length and returns a single number. All the dot products for all vectors in a given subject may then be summed to provide a strength score for that subject for the given text.
For example, in any subject there may be many topic vectors and for most of these vectors the dot product will be close to zero, even if the given text is about that subject. Since there are some subjects with hundreds of topic vectors, there may be hundreds of small dot products that may provide a significant score even when they are close to zero. In another embodiment, discrimination may be applied where any dot product that has a value less than a certain threshold (e.g., 0.2, etc.) is ignored and only stronger dot products above the threshold are summed for the score. In another embodiment, this threshold may be empirically verified against the test set, to provide a better classification to subject.
Also, in one embodiment, a number of topics may be widely different, with some subjects having orders of magnitude less topic vectors than others. Such an example scoring may not be equal given the differences in numbers. A linear scaling on the score based on the number of topic vectors may be applied, which may reduce the score of the largest subject. In some examples the reduction may be up to 30%. This may provide a fairness correction to the score, which may help in the classification.
In addition, in exemplary test examples, once all scores are calculated for all the subjects, then these scores may be sorted, and the most probable subjects may be returned, which may provide an array of subjects and strengths. In another embodiment, hashes may be used to store the topic vectors to provide a simple lookup of words and strengths in the code.
Further, in one embodiment, one or more topic vectors may be changed from hashes of words and strengths to an ordered byte stream (e.g., an ordered byte stream of 4-byte integers, etc.) with another array of strengths (e.g., 4-byte floating-point strengths, etc.). These may then be accessed as arrays in a complied c routine, and may be cached in high performance memory. This may change the classification time from a few seconds each, to a little less than a tenth of a second to classify each document.
In one embodiment, a large set of web sites linked to slash tags may be created, where the slash tags include defined subjects of high quality data. These websites may represent a small percentage of data available on the Internet, but may provide a high quality set of text for each defined subject. Text from these high quality websites may be processed by computer systems using Latent Dirichlet Allocation (LDA) analysis to determine sets of topics for each subject. These sets of topics may then be used to classify any text, to determine an array of most probable subjects. In this way, the previously uncategorized sources of text may be analyzed and categorized by subject automatically, which may improve a number of uses such as indexing, data matching, and searching.
In another embodiment, natural language processing (NLP) and matrix inversion of the word space to the document space may be used to reduce the complexity of the natural text. With the wide availability of large scale computing power, larger and larger set of documents may be used, and the complexity may be reduced such that general information about the text may be determined.
One technique that may be used for data reduction is Latent Dirichlet Allocation (LDA), where for a set of documents a set of topics is assumed and for each topic a set of words and strengths is assumed. Then, using a Bayesian analysis, the most probable sets of words for the topics may be calculated. These topics may be related sets of words that appear repeatedly, most probably at the frequencies calculated. In this way the space of words and documents may be reduced to a space of most common topics, to provide an easier way of handling and calculating general information for a set of documents. Thus, for example, topics may be distributions over words. And we can assign to documents, or sets of documents, a distribution over these topics.
In one embodiment, the space of topic vectors may provide a simplified analysis of documents, which may provide some ability to classify text, and see changing topics over time. In another embodiment, topic vectors may be grouped into subjects, to further reduce the data. For example, a set of topics may be labeled as a certain subject, and then the text may be discussed as an even smaller set of data. This reduction may determine a general subject of a set of documents to see if it can be of use to a general audience.
In another embodiment, slash tags may be defined for a set of subjects that divide up information on the Internet, defining high quality sources of text. In yet another embodiment, one or more users may include searches on data that is only labeled with a particular slash tag. Results may then only look for web pages based on the subject defined by the slash tag, for example, sports, history, fashion, or any of various others.
It should be noted that divisions of data and/or classification systems such as slash tags are used in an exemplary fashion and are not intended to be limiting. Any of various divisions of data and/or classification systems may be used. In one example, by using slash tags to search, the set of slash tag data may provide a corpus of a large amount of text, which may be labeled with a certain subject. In another example, training data, which has been labeled, may be used for analysis. Using LDA, sets of topic vectors may then be found, which may be related to a certain subject. These sets then may be used to provide classification of any random text, as to what are the most probable subjects that are relevant to that text.
