KNOWLEDGE BASE-BASED CONCEPTUAL-GRAPH EXPANSION SYSTEM

摘要

A conceptual-graph expansion system is disclosed. The system may comprise: a relation triple knowledge base for storing reference information for expansion of a conceptual graph; and a conceptual-graph expansion module for generating a conceptual graph in a form expanded using reference information stored in the relation triple knowledge base, on the basis of a conceptual graph converted from a query expressed as a natural-language sentence.
