Temporal and Spatial Analysis to Personalise an Agent’s Dynamic Belief, Desire, and Intention Profiles

The paper addresses the dynamic belief, desire and intention profiles that can be made of an agent following a particular route, for example through a city. It assumes that location of an agent has effects on his beliefs desires and intentions and that the history of agent’s mobility and observed states in different locations can be used to predict his future states if the location is being permanently observed. A formal spatial route language is introduced. Formal relationships between the intentional notions, and the spatial behaviour of an agent are defined. As an application an information agent architecture for reasoning about the intentions of the customers of a mobile location-based service is described.
