Appl. No.:

15/984714

Inventors:

- Miamisburg OH, US
David Steiner - Waynesville OH, US

Assignee:

LexisNexis, a division of Reed Elsevier Inc. - Miamisburg OH

International Classification:

G06F 17/30

Abstract:

Computer programs for searching a collection of electronic documents are disclosed. A computer program for searching a collection of electronic documents, includes instructions that cause the computer to carry out steps of: replacing a set of synonymous terms appearing in a paragraph with a set of standardized paragraph terms, where each standardized paragraph term has an associated term weight and generating standardized search terms in response to a search query, generating paragraph scores for paragraphs of a document based at least in part on the associated weights of standardized paragraph terms that match one or more of the standardized search terms. The computer program further includes determining overall document scores for the electronic documents based at least in part on a combination of the paragraph scores, and determining a set of matching documents, wherein the set of matching documents is ordered using the overall document scores.

Abstract:

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.

Abstract:

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.

Assignee:

LexisNexis, a division of Reed Elsevier Inc. - Miamisburg OH

International Classification:

G06F 17/30

Abstract:

A computerized method of searching a collection of electronic documents may include comparing search terms to sets of paragraph terms associated with paragraphs in the documents. Search terms and paragraph terms may be standardized, prior to the comparison. The method may also include generating paragraph scores for the paragraphs using term weight values associated with paragraph terms that match search terms, generating paragraph scores for the paragraphs, and using the paragraph scores to generate overall document scores. The method may also include using the overall document scores to determine a set of search results and providing the search results to a display.
