AUTOMATIC ANALYSIS OF REPOSITORY STRUCTURE TO FACILITATE NATURAL LANGUAGE QUERIES

Abstract

Techniques for analyzing a repository are described herein. A method for analyzing a repository may include obtaining a list of known persons in a repository based on objects, users, and groups retrieved from the repository. The method may further select one of the objects having a field and a value, and then determine whether the field of the selected object is a facet based on a probability that the field of the selected object has a limited number of possible values. In analyzing the repository, a repository information archive may be generated. The repository information archive may include the relationship between the selected object and at least one other object, statistics and counts related to properties in the selected objects, and whether or not the field of the selected object is a facet.

Description

BACKGROUND

Repositories hold data such as emails, text documents, executable files, and the like. This data may be retrieved from the repository in response to a query. The process of retrieving this data in a fast, precise, and accurate way can become more difficult based, in part, upon how much data may be stored in the repository.

SUMMARY

According to one embodiment of the present invention, a method for analyzing a repository includes obtaining a list of known persons in a repository based on objects, users, and groups retrieved from the repository. The method may further select one of the objects having a field and a value, and determine whether the field of the selected is searchable, contains special values, or is a facet, where the field is defined as a facet based on a probability that the field of the selected object has a limited number of possible values. The method may also count a number of documents to contain a property for each property retrieved from a repository and generate a repository information archive. The repository information archive may include a persons matrix, the relationship between the selected object and at least one other object, statistics and counts related to properties in the selected objects, and whether or not the field of the selected object is a facet and a distribution of values in a facet.

DETAILED DESCRIPTION

The subject matter disclosed herein relates to techniques for comprehensive analysis of a repository structure. Retrieving data from a large document repository based on queries can be a serious challenge.

For example, a growing number of queries on databases and repositories are Natural Language (NL) queries, and may be made with human speech and phrasing. A request originating from a speech based NL query may have a large number of possible meanings for each of its words. This results in a huge number of combinations that could map to a large number of queries. Retrieving results based on identifying a collection of the words, as interpreted from the NL query, may be prone to errors and also may be very imprecise. A paradigm based on a collection of words for query access to repositories may lead to large recall and low precision.

In the present disclosure, a repository may be analyzed to improve precision of query results. In one example, static analysis may be performed on the repository in order to generate an information structure to be used in interpreting queries and query retrieval processes. Static analysis may be static in its performance prior to the execution of a set of queries on the repository.

The output of this repository analysis may be a repository information archive which may represent the repository structure entities. The repository information archive may be used to aid in interpreting queries, executing queries on the repository, or may provide repository structure information as needed. The repository information archive may be an extensible markup language (XML) document and extensible hypertext markup language (XHTML) document, or any other markup language document that includes the structural information that may have been gained through repository analysis. Other information may also contribute to the repository information archive or its use, including related information about repository users found in data external to the repository such as in a lightweight directory access protocol (LDAP) or other external information relevant to the analyzed repository information. Each of these pieces of information may contribute to a boost in accuracy as the query interpretation can be more tightly coupled with the specific repository structure information than an interpretation that would otherwise occur. In some examples, the repository information archive may be used to aid in interpretation of queries in written form as well as queries received in the form of NL or human speech. The comprehensive analysis performed on the repository may aid in converting a NL query into a structured query that includes user specific patterns and repository specific structure to yield more accurate results to the query.

FIG. 1 shows a block diagram of an example computing system 100 to analyze a repository. The computing system 100 may include a computing device 101 having a processor 102, a storage device 104 comprising a non-transitory computer-readable medium, a memory device 106, a display interface 108 communicatively coupled to a display device 110. The processor 102 may be a main processor that may be adapted to execute the stored instructions. The processor 102 may be a single core processor, a multi-core processor, a computing cluster, or any number of other configurations. The memory unit 106 can include random access memory, read only memory, flash memory, or any other suitable memory systems. The main processor 102 may be connected through a system bus 122 to components including the memory 106, the storage device 104, and the display interface 108. The display device 110 may be an external component to the computing device 101, an integrated component of the computing device 101, or any combination thereof.

The storage device 104 may include a repository analyzer 112 to generate a repository information archive. The computing device 101 may include a network interface 114 communicatively coupled, via a network 116, to a repository 118 and a remote device 120. In an example, the repository analyzer 112 may be configured to retrieve repository users and groups. The retrieval of this information may be used to analyze the frequency of user associations with other users groups and concepts. Further, knowledge of a particular use of any given user, interactions, history of use, as well as information associated with an occurrence of data indicating a given user in various fields in the repository such as: Sent-to, To, Creator, etc. may aid in analysis of user relationships to other users and may help with error correction in both generation of the query and correction of speech queries. For example, for a search on “Mary Poppins” a first search may be done to determine if “Mary Poppins” exists in a “from” or “to” field of objects in the repository. If not, then the phrase “Mary Poppins” may not be searched as a name of a user, but instead as a string without any associated significance as being a name.

In an example, the repository analyzer 112 may be used by a computing device 101 to generate a persons matrix. In a persons matrix, a repository analyzer 112 may obtain for each user in the repository 118, a list of contacts. In one example, the repository analyzer 112 may also include a count of other additional users that a particular user may send and receive emails from. In query interpretation, a repository structured with this information may provide more accurate results. In an example, additional user information of a repository may be analyzed including information about collaboration of one or more users to generate the data in the repository.

The repository analyzer 112 may be logic or a logical unit that at least partially includes hardware to implement the logic and processes it may be storing. The repository analyzer 112 may be implemented as discrete modules performing various functions, an integrated module of a parent process, or any combination thereof. In embodiments, the repository analyzer 112 may be implemented as instructions executable by a processing device, such as the processor 102. The instructions may direct the processor 102 to identify a data flow source statement within a computer program and identify a feature read at the source statement. The feature may include structure and values for a repository of documents. For example, the structure information and generated repository information archive may include various authors of the documents, when they were generated, modified, or other structural data about not only the repository, but also the objects and fields in that repository.

The block diagram of FIG. 1 is not intended to indicate that the computing device 101 is to include all of the components shown in FIG. 1. Further, the computing device 101 may include any number of additional components not shown in FIG. 1, depending on the details of the specific implementation.

FIG. 2 shows a block diagram 200 of an example repository 118 to be analyzed. As illustrated in FIG. 2, a repository, such as the repository 118 of FIG. 1, may be accessible to a repository analyzer, such as the repository analyzer 112 of FIG. 1, to generate a repository information archive 202. The repository information archive 202 may contain structural information about the repository 118 as well as other results from the repository analyzer 112.

As illustrated in FIG. 2, the repository 118 may include multiple objects (Object 1204, Object 2206, Object 3208, and Object 4210). Like items are as described in FIG. 1. These objects 204, 206, 208,210 may be any collection of data stored in the repository 118 and may include text, documents, emails, temporary files, executable files, databases, spreadsheets, presentations, or any other collection of data that may be stored in the repository 118. Each of the pictured objects 204-210 may each contain data that is here referred to as content (Content 1212, Content 2214, Content 3216, and Content 4218). In an example, content data may be data to provide text, images, or other suitable information for an end-user. Content can include the text of a text document, the video of a video file, the message of an email, or other similar information. Each object 204, 206, 208, 210 may also contain a field (Field 1220, Field 2222, Field 3224). In an example, the fields 220-224 may include information about their corresponding objects 204, 206, 208 or their corresponding contents 212, 214, 216. In an example, the fields 220, 222,224 may include metadata about the corresponding objects 204, 206, and 208 and contents 212, 214, and 216. As illustrated in FIG. 2, Object 4210 does not include a field, as objects 204, 206, 208, and 210 may vary in structure. The various fields that are present in both the repository 118 as a whole and within each object 204, 206, 208, 210 may be analyzed by the repository analyzer 112 to generate the repository information archive 202.

The repository analyzer 112 may also analyze each object 204, 206, 208, 210 to find and catalog the properties of each object 204, 206, 208, 210. The repository analyzer 112 may also determine which, if any of the object's properties are “searchable,” contain special characters, or may be used in future queries. In an example, the repository analyzer 112 may also detect relations between objects 204, 206, 208, 210. All of this information or any combination of it may be used in the generation of the repository information archive 202 to aid in formation of semi-structured queries.

In another example, each field 220, 222, 224 of a corresponding object 204, 206, 208 may be a facet. A field may be considered a facet if the values in a field are limited to either a pre-defined choice list or if a limited number of values populate the field throughout the repository and these values make up a majority of the values possible in the field. For example, Object 1204 may be an email and the email includes content 1212 that may be a message of text. In this example, Object 1204 may also include Field 1220 that may be a “sent by:” field to indicate a user that the email was sent by. A repository analyzer 112 may then determine if a “sent by:” field qualifies as a facet by a determination of if the number of users for a repository 118 may be limited. In this example, if the possible options for Field 1220 (as a “sent by” field”) may be limited or finite, then Field 1220 may be considered a facet. In contrast, Field 2222 may be a “date created” field to indicate when Object 2206 was created. In this example, the possible options for this field, i.e. days, are not finite for the repository. In this example, a “date created” may not be considered a facet.

In some examples, however, a field 220, 222, 224 may be considered a facet if it may be facet-like or bears sufficient similarity to a field that may be a facet. In an example, a field 220, 222, 224 may be facet-like if the values are finite in a specific repository 118. For example, while the number of days that are possible in a “date created” field are not limited, a repository analyzer 112 may determine that all of the values of the “date created” fields for each object 204, 206, 208, 210 in the repository 118 are within a certain range and are therefore limited. In this example, the “date created” field may be considered a facet. In an example, the determination of if a field 220, 222, 224 may be a facet or not may be included in the repository information archive and used in query interpretation and execution on the repository 118. In example, a field 220, 222, 224 may also be considered a facet by determination if the field values are limited to a pre-defined list of options or a de facto limited list calculated by looking at the specific content of the repository 118. Analysis of the specific content of the repository 118 may include counting the number of documents containing this property, the number of documents containing this value, and other similar measures.

The repository analyzer 112 may count various features of the repository 118. In an example, the repository analyzer 112 may count the number of objects 204, 206, 208, 210 to contain not only a field, but also how many contain a particular type of field. This information may be structured, put into the repository information archive, and may help with ranking and scoring a query by excluding search terms that would not normally return any results from the repository 118. For example, a counted number of properties may help provide a denominator for calculating the likelihood of asking for a particular property in a query.

FIG. 3 shows a block diagram of an example object of a repository. Like items are as described in FIG. 1 and FIG. 2. As illustrated in FIG. 3, object 1204 may include field 1220 that includes multiple values (value 1300 and value 2302). In one example, the field may be a “To:” field that may indicate users initially to be sent object 1. As illustrated, Field 1220 may include both Value 1300 “To: Liz” and Value 2302 “To. Martin”. These two values need not be alphanumeric names but may also be any other data value suitable for a type of field. User values may include users that are groups of users. The repository information archive may calculate a user relationship number to indicate the frequency a first user and second users are both associated with the same object. The repository information archive may calculate a user-value relationship number to indicate the frequency a user identity may be associated with a particular value that may exist in another field of an object. The repository information archive may calculate a value-value relationship number to indicate the frequency a first value and a second value found in fields of an object are both associated with the same object.

In an example, a repository analyzer 112 may analyze multiple values within Object 1204 and produce a count of the frequency of each value's appearance in various fields 220, 222, 224. In an example, this may include calculating the frequency a user value may be included in different types of fields 220, 222, 224 such as the “sent to:” and “to:” fields. In an example, a type of field may be based on the value contained within the field rather than explicit designation.

In an example, the repository analyzer 112 may be used by a computing device 101 to find correlations between users and fields not including user values, such as a “subject” field. In an example, the repository analyzer 112 may recognize that user values—Value 1300 “To: Liz” and Value 2302 “To: Martin”—were both included in Object 1204. In this example, the repository analyzer 112 may also correlate these values to a “subject” of Object 1, and use this information to return objects results with similar or related subjects in response to queries, or in query interpretation.

FIG. 4 shows a block diagram 400 illustrating an example method of generating a repository information archive. The method begins at block 402 where a repository with a plurality of objects may be identified. The repository may include multiple objects where each object may have multiple fields, and where each field has multiple values.

At block 404, a plurality of objects having a field and a value are selected. In addition to the general field properties designated by the repository, repository analysis may discover additional properties about every object and field rather than only obtaining repository provided structure information.

At block 406, it may be determined whether or not the selected object may be a facet. In an example, a field may be a facet if it has a limited set of possible values and it can be defined as such throughout the repository. In some cases, even if the field does not qualify as a facet, or when not explicitly defined as such, a repository analyzer may search for actual instances of a field throughout the repository. Depending on what the repository analyzer finds, a field may still be regarded as a facet if the values are used in a limited way. With each newly identified facet in a repository, the precision of queries may be increased as the ability to restrict a query by certain values limits irrelevant responses to queries which lack that certain value. In an example, the probability that a field qualifies as a facet may be based on an analysis of the repository to find if, and to what extent the values of the particular field are limited. In completely limited value fields, the probability that the field may be categorized as a facet are much higher than if there are fewer limitations on the number of values repeated in the repository.

At block 408, a repository information archive may be generated from all previous information used, gathered, and calculated from the analysis performed in this method. This generation may include the designation of if a field qualifies as a facet, or any other calculation from other steps in the analysis method. In an example, the analysis may be static in its performance prior to any queries being executed on the repository. In an example, if new information may be added to the repository after a repository analysis may be run, the repository analyzer may be rerun to generate an updated repository information archive. In an example, the analysis of the repository omits analysis of the content of an object and instead analyzes only the fields to increase precision of queries.
