Grounded Contextual Reasoning enabling Innovative Mobile Services

This paper reflects our findings on the technological feasibility of a mobile service scenario. We will show that despite the scenario being quite ordinary for endusers, the required service support functionality is rather complex. The realisation hinges on intricate grounded contextual reasoning about location information, user profiles and other situational context information. In particular, existing engineering methods and state-of-the-art technologies very well enable, for example, timely warning of a sales manager, who is late for and on his way to a business meeting. Furthermore, such techniques readily enable recommending the ‘best’ alternative travel schemes such that he arrives in time for his meeting. We report on our findings with implementing a sophisticated location reasoner of such a commuter-assistant that ultimately aligns commuting and meeting preference schemes of the sales
