SEMANTIC RANKING USING A FORWARD INDEX

摘要

Methods, computer systems, and computer-readable media for generating semantic ranking features using a forward index are provided. A search query is received and is analyzed for one or more semantic units including semantic patterns, topical categories, and entities. A forward index comprising a plurality of documents is accessed and semantic units associated with each of the documents are analyzed. The semantic units include semantic patterns, topical categories, unigrams, bigrams, and entities. Documents who share substantially similar semantic units with the search query are identified, and the ranking of the identified documents is adjusted based on the substantially similar semantic units.
