Filed:

Aug 26, 2010

Appl. No.:

12/869456

Inventors:

Paul Zhang - Centerville OH, US
Harry Silver - Shaker Heights OH, US
David Steiner - Waynesville OH, US

Assignee:

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

International Classification:

G06F 7/00

US Classification:

707758, 707769

Abstract:

A computer-implemented method of generating an issue library from a corpus of documents defining a citation network includes semantically linking, by a computing device, electronic documents within the corpus of documents by pairing reasons-for-citing in citing documents with cited-text-areas in cited documents and storing citation entries associated with the semantically-linked electronic documents in a citation-pairing metadata file. The method may further include searching the citation-pairing metadata file for reasons-for-citing and cited-text-areas that are semantically similar to at least one issue to thereby group similar documents and reasons-for-citing by issue, and storing information regarding groups of semantically-similar reasons-for-citing and cited-text-areas in a plurality of issue library metadata entities. Each issue library metadata entity is associated with an individual issue.

Assignee:

LEXISNEXIS, A DIVISION OF REED ELSEVIER INC. - Miamisburg OH

International Classification:

G06F 17/30

US Classification:

707723, 707E17014

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.

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.
