Ontology-Based Query Formation and Information Retrieval

Abstract

With the introduction of new technologies such as WAP, HSCSD, GPRS, UMTS, and Bluetooth, it is believed that the e-commerce arena will sooner or later merge its applications with handheld devices to create more opportunities for the birth of mobile commerce (m-commerce). However, m-commerce is largely unrealized to date because there still does not exist a single killer application that can attract wireless users to use wireless services. According to a recent survey by Gartner, Inc., besides the importance of coverage of wireless network and pricing issues, the wireless Internet and data services is the next crucial factor that attracts users to use wireless service. As such, there is a need to improve the data services over the wireless network. One of these services is the information retrieval service.
