Abstract

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 the Gartner, Inc. (Wong, 2005), 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 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. This article discusses the usage of ontology to create an efficient environment for m-commerce users to form queries. The establishment of a method that combines keyword searches with using ontology to perform query formation tasks further allows a more flexible m-commerce environment for users. Also, with the use of genetic algorithm, it is hoped that query effectiveness can be achieved, at the same time saving computational time.
