Performing semantic graph search

Abstract:

Provided are techniques for performing entity-based semantic graph search. Semantic extraction is performed on content items to identify entities. A semantic graph is generated with a vertex for each of the content items, each of the entities, and each user associated with any of the content items and with edges between vertices representing relationships, wherein each of the edges is encoded with metadata about a type of a relationship and a strength of a relationship. A vertex structure is generated that contains identifiers of the content items, the entities, and each user mapped to vertices in the semantic graph. In response to receiving a search request with a search term, using the semantic graph and the vertex structure to identify search results for the search term.
