摘要： Systems and method for generating concepts from a document corpus are disclosed. In one embodiment, a method for generating concepts from a document includes retrieving, a plurality of terms stored within a first lexicon. The method further includes, for individual terms stored within the first lexicon: determining a first frequency of the term within the document corpus, and determining a second frequency of the term within a comparison document corpus including a plurality of comparison documents, wherein the comparison document corpus is different from the document corpus. The method further includes, for individual terms within the first lexicon: determining a difference between the first frequency and the second frequency, comparing the difference between the first frequency and the second frequency to a comparison metric, and, when the difference between the first frequency and the second frequency satisfies the comparison metric, storing the term as a concept within a second lexicon.

摘要： Systems, methods, and computer-executable instructions described herein relate to surfacing a set of documents ranked by their relative value calculated as a tabulation of how often they are cited for a specific purpose. In one embodiment a computer machine is configured to receive a query as computer machine input, automatically determine at least one concept contained within the query and automatically normalize the at least one concept contained within the query, thus creating at least one normalized concept. The computer machine is further configured to automatically compare the at least one normalized concept to at least one document centric concept profile associated with the set of content items in the corpora; and automatically surface a set of documents matching the document centric concept profile. The set of documents are ranked according to a reference value assigned to each document for a normalized concept.

摘要： Systems and methods for generating issue networks are disclosed. In one embodiment, a computer-implemented method of generating an issue network from a document corpus includes searching, using a computer, the document corpus for a set of documents discussing a starting issue, wherein the starting issue is one of a plurality of normalized issues defined by the document corpus. The method further includes determining a set of normalized issues discussed by the set of documents discussing the starting issue, wherein the set of normalized issues also includes the starting issue, and determining instances of co-occurrences of individual normalized issues of the set of normalized issues within individual cases of the set of documents. The method also includes linking individual normalized issues of the set of normalized issues based on their co-occurrences within the set of documents, wherein the linked individual normalized issues at least in part define the issue network.

摘要： Systems, methods, and computer-executable instructions for identifying a document are described. A method includes receiving a query from a graphical user interface having one or more concepts, normalizing a set of terms or concepts in the query to create a normalized query, comparing the normalized query to a set of document centric concept profiles associated with a set of documents in a corpus, where each document centric concept includes a plurality of concepts and at least one reference value for each concept, where the reference value is calculated by tabulating the number of times a document associated with one of the document centric concept profiles is cited by a citing instance for the concept, and surfacing a document from the corpus with the highest reference value for the concept.
