SYSTEM FOR GENERATING TEMPLATE USED TO GENERATE QUERY TO KNOWLEDGE BASE FROM NATURAL LANGUAGE QUESTION AND QUESTION ANSWERING SYSTEM INCLUDING THE SAME

摘要

The present invention relates to a system for generating a template used for generating a query about a knowledge base from a natural language query, and a query response system including the same. According to one exemplary embodiment of the present invention, the system comprises: a natural language query pretreatment unit transferring a natural language query to a natural language recognition system to acquire resources including each of ontology components corresponding to tokens extracted from the natural language query; a graph analysis unit generating graph data including resources based on an ontology schema of the knowledge base formed with knowledge data units, and generating at least one knowledge data unit from the graph data; and a template generation unit generating a sample query from the at least one knowledge data unit and generating a template corresponding to a pattern of the resources from the sample query.
