Abstract: Disclosed is a computer implemented system and method of discerning an entity class from a query. A query is received and broken into query fragments comprised of terms. The terms of the query fragments are compared to terms belonging to one or more bag of words models with matches removed. The bag of words models to which the terms removed from the query fragments belong are remembered. The remaining n terms of the query fragments are processed to obtain query phrases containing 1-n grams from the query fragments. Each query phrase is submitted to a search engine. A sampling of snippets from the search results are extracted. Non stop words from the snippets are stemmed. A similarity score is computed for the stemmed snippet words with respect to each entity class bag of words model. Snippet entity classes are selected based on the bag of words models having the highest similarity score with the stemmed snippet words.
