ABSTRACT:
A computerized method for organizing information retrieval based on the content of a set of primary documents. The method generates answer hypotheses based on text found in the primary documents and, typically, a natural-language input string such as a question. The answer hypotheses can include phrases or words not present in the input string. Answer hypotheses are verified and ranked based on their verification evidence. A text corpus can be queried to provide verification evidence not present in the primary documents. In another aspect the method is implemented in the context of a larger two-phase method, of which the first phase comprises the method of the invention and the second phase of the method comprises answer extraction.
