Natural language query interface in SMS/MMS-based spatial information service
Xiaoqiu Le, Chongjun Yang, Wenyang Yu, Feixiang Chen · 2005
To solve the problem of poor interface of SMS/MMS, we adopt natural language query interface as an optional approach for the user who does not know any command format. Since there is no service code in natural language query string, we have to evaluate what kind of service the user wants. In this paper, we propose an approach of mapping natural language query string to standard commands that servers understand. We also discuss the extraction process of spatial semantics from unstructured query string based on the spatial semantic roles. Meanwhile, the system framework of the prototype is given, and the potential problems and the future works are also discussed.
