Positive/negative facet identification in similar documents to search context

Abstract:

Facet-based search processing is provided which includes receiving a query search context for querying documents of a document set, and retrieving, by similar document search processing, a document subset from the document set. The document subset includes documents of the set most similar to a search document of the query search context. Facet analysis processing is used to generate M candidate facets most-related to the query search context, and facets of the M candidate facets associated with documents of the subset are identified, and classified into a positive facet set and a negative facet set based, at least in part, on extent of facet commonality across the documents. A listing is of the documents in the document subset is provided, with the listing highlighting facets of the positive facet set.
