595709 Disclosed is a computer system (200) with a memory and at least one processor for facilitating a search and identification of documents stored in a memory device. The system (200) includes a processor which receives a query with a set of search terms, identifies an initial result set of stored documents that are relevant to the query, and identifies a document from the initial result set. An information retrieval (IR) score generating component (206) determines a score value representing a degree of similarity between the identified document and the query. The score value is based on a similarity between one of the query search terms and metadata describing subject matter of the identified document. Also included is a citation network of baseline query results which has a first set of documents that cite to the identified document and a second set of documents cited to by the identified document. A citation component (208) locates the identified document in the citation network, and determines a new score value of the identified document as a function of the score value and a quantity and a quality of documents within the first and second set of documents. An activity score component (210) locates documents in a subject matter community of the identified document, outside of the citation network, that refer to the identified document. The activity score component (210) calculates an activity score value of the identified document based at least in part on a number of times the identified document is referred to in the subject matter community and weighs the new score value with the activity score. A display device displays a report reflecting a ranking of the identified document based on the weighted new score value. |
