ABSTRACT:
A system, method and computer readable medium are disclosed. The method embodiment relates to a method of computing score of candidate answers to a database query. The method comprises receiving a database query, assigning a first score to a match to the query, the first score being associated with a relative importance of an individual keyword in a collection of documents based on all structural and content predicates in the query, assigning a second score to the match, the second score being associated with a relative importance of a keyword in an individual document and using the assigned first score and second score to compute an answer score for the query.
