Natural Language Query System for RDF Repositories

, and . Proceedings of the Seventh International Symposium on Natural Language Processing (SNLP), Pattaya, Thailand, (2007)

Abstract

We report insights gained from a project of enabling natural language question answering using information stored in RDF repositories targeted to mobile phones users. We present ways of improving portability of natural language interfaces across different data domains based on the Natural Query (NQ) system. NQ enables portable NLI to RDF repositories, can effectively rank different semantic interpretations of a natural language questions with respect to information in RDF repository. NQ can retrieve information that answers the question and can be used for additional explanation, disambiguation or guiding the dialog. We have successfully applied NQ to creating natural language access capability for mobile device data and for two externally hosted repositories - a corporate personnel directory and a job search database.
