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.

System and method for providing structure and content scoring for XML

A device and a method are provided. Approximate match operations are performed for each of a group of attributes for each of a group of tuples with respect to a query to create a respective ranking for each of the group of attributes. The rankings of the group of attributes are combined to provide a ranking score for each of the group of tuples. Data representing a ranking score of each of the group of tuples is generated according to a position of a respective ranking of each one of the group of tuples for a first k positions of the ranking. K of top ranked ones of the group of tuples are identified based at least in part on the generated data, wherein a number of the group of tuples is n and k&#x3c;n.
