<P>PROBLEM TO BE SOLVED: To provide a system, computer-implemented method and computer program product for preparing and navigating a query tree including a plurality of query nodes and informational nodes. <P>SOLUTION: Each query node is associated with a prompt, branching criteria and keywords. A current query node provides a prompt to a user and a user response is received and analyzed to identify branching criteria and keywords from the user response. The method navigates to another node in the query tree in consideration of the branching criteria received in the user response and a comparison between the keywords received in the user response and the keywords associated with the query nodes. The comparison may validate navigation to a destination node corresponding to the branching criteria or the comparison may indicate incorrect navigation of the query tree. Corrective navigation can be implemented in various ways based upon the keywords received in the user response. <P>COPYRIGHT: (C)2011,JPO&INPIT |
