Path expression processing in Korean natural language query interface for object-oriented databases

A natural language query interface for databases provides the user friendliness in retrieving the desired information by querying in a native natural language. Up to now, many natural language query interfaces for conventional databases have been developed. However, the field of natural language query interfaces for object-oriented databases which have recently started to emerge as the next-generation databases has become a new research area. This paper describes a processing technique to manipulate natural language representations of path expressions. From the fact that the path expression is one of the key features in the object-oriented data model, a frame based decomposition method is proposed for efficient processing
