<p><P>PROBLEM TO BE SOLVED: To provide a system and method that disambiguate between an incorrectly recognized spoken query and a correctly recognized spoken query for which there are no currently available documents in a database. <P>SOLUTION: The method generates a list of unavailable categories of documents. The method also generates surrogate documents which include query terms similar to the categories of unavailable documents. Each surrogate documents also includes a description which indicates why the document is not available. The surrogate documents are included in the database along with the available documents. Spoken queries are matched against all documents in the database including the surrogate documents. If a surrogate document is retrieved, then a user is presented with the description that describes why that category of documents is not available. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
