ONTOLOGY CONSTRUCTION METHOD AND DEVICE FOR DIALOGUE SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an ontology construction method and device for a natural language dialogue system.SOLUTION: An ontology construction method includes the stages of: generating a domain ontology plane based upon in-plane relation information on a domain defining relation between a plurality of domain nodes; generating a travel ontology plane based upon in-plane relation information on a travel defining relation between a plurality of travel nodes; and generating an individual name ontology plane based upon in-plane relation information on an individual name defining relation between a plurality of individual name nodes. Therefore, a domain, a travel and an individual name as components of a dialogue frame can be accurately determined by structuring multiple ontology planes for the dialogue system, and consequently efficient system answering can be performed.SELECTED DRAWING: Figure 8
