Abstract (en)

[origin: WO9905621A1] A system (1480) filters documents in a document set retrieved from a document store in response to a query. The system (1480) obtains (1830) a first set of logical forms based on a selected one of the query and the documents in the document set. The system (1480) obtains a second set of logical forms based on another of the query and the documents in the document set. The system (1480) then uses natural language processing techniques to modify (1832, 1834) the first logical forms to obtain a modified set of logical forms. The system (1480) filters (1836) documents in the document set based on a predetermined relationship betwwen the modified set of logical forms and the second set of logical forms.
