  • QUERY GENERATION AND TIME DIFFERENCE FEATURES FOR SUPERVISED SEMANTIC INDEXING
    Publication number: 20140122388
    Abstract: Semantic indexing methods and systems are disclosed. One such method is directed to training a semantic indexing model by employing an expanded query. The query can be expanded by merging the query with documents that are relevant to the query for purposes of compensating for a lack of training data. In accordance with another exemplary aspect, time difference features can be incorporated into a semantic indexing model to account for changes in query distributions over time.
