Abstract
Systems and methods are provided for identifying factual information in a written document. Named entities and corresponding noun phrases are identified in the written document. A query is built by combining one of the named entities with a respective one of the noun phrases. The query represents an assertion of a potential fact. The query is submitted for comparison with a fact repository which assesses whether the query presents a factual assertion. If the query presents a factual assertion (e.g., it matches a fact within the fact repository), a match is returned. Various modifications may be made to the queries to return additional matches and various combinations of filters may be applied to the matches to filter out less relevant matches.
