Abstract

A method and system for obtaining semantically valid chunks for natural language applications are disclosed in the present invention. The method includes the following steps: identifying predicates, objects and comparison operators in a natural language query; binding the identified predicates and objects using the identified comparison operator; replacing all occurrences of string comparator operators in said natural language query with corresponding mathematical operators; binding predicates and objects of same data type; checking compatibility of bound predicates and objects using domain ontology; binding string objects to their compatible predicates using domain ontology; forming constraint predicate sets from the remaining predicates of the query in order to find semantically valid chunk sets from said natural language query; syntactically parsing natural language query for absolving ambiguities; determining the depth between any two predicates using domain ontology, thereby providing a syntactically and semantically valid chunk set adapted to be used as a query.
