Abstract: A method of retrieving information includes obtaining access to a plurality of documents comprising document terms, receiving a lexicon including a plurality of lexical terms, receiving a query, identifying a plurality of search terms in the query by decomposing the query, determining at least one match of the search terms to the lexical terms, determining a plurality of matches of the search terms to the document terms, and scoring each of the documents based on the at least one match to the lexical terms and the matches to the document terms.

Abstract: A computer-implemented method, a computer program product, and a computer processing system are provided. The method includes identifying, by a processor using a topic identification system, topic information for a source topic-domain in a corpus. The method further includes extracting, by the processor, an entity from the source topic-domain. The method also includes tagging, by the processor, the entity with the topic information to obtain a tagged entity that includes a tag specifying the topic information. The method additionally includes storing the tagged entity in a memory device. The method further includes performing, by the processor, downstream processing of the tagged entity in a natural language processing pipeline using the tag of the tagged entity as an additional data point.
