Remarkable growth of the mobile internet service industry in Japan proved that present method of service menu system is insufficient to guide users efficiently to the services they need. This paper introduces our research activities toward realization of Task-oriented menu system, which enables users to search for mobile services by "what they want to do" instead of by "name of category". Although efficiency of the menu system has been proved on a prototype system, it is limited and capable of supporting limited activities; mobile users' activity in a theme park. Thus we need to analyze wider area of user activities to list up the situations and task models of users as many as possible to expand the prototype menu to cover larger scale of the services. We introduce OOPS (Ontology-based Obstacle, Prevention and Solution) modeling method which supports description of the necessary situations. We have applied the method to model "Tourism" domain which covers a broader spectrum of users' actions. We have evaluated the coverage of the OOPS model by verifying situations represented in the model developed and those situations assumed to be supported by i-mode official services. The model covered about 97% of the assumed situations of mobile internet services. Reorganizing "contexts" in the model, we aim at developing task oriented menu system as a next step.
