NLMO: Towards a Natural Language Tool for Querying Moving Objects

In recent years, natural language processing has received increasing attention in the field of database. The main task is to bridge the gap between non-expert users who are not familiar with formal query languages and the system executable language. In this demo, we develop a tool called NLMO that performs the translation of NL questions to executable query languages over moving objects databases. The tool well supports spatio-temporal range queries and nearest neighbor queries. We demonstrate the tool by reporting executable languages translated from the natural language input.
