Ontology based information distribution in the pervasive display environment

Displays providing different information at many different locations are exponentially increasing. Under this pervasive display environment, users may be provided with customized information in real-time at each point of interest (POI). However what type of information to be provided is not easy to define. In this paper, architecture for information distribution based on the ¿environment ontology¿ is proposed. Display system embedded with the environment ontology relates the location with available services/information with the user profile. We implemented information push and pull system SAS (Shopping Agent Service) integrated with environment ontology to support human decision in the process of purchasing a product within a shopping mall. SAS demonstrates how the information is distributed harnessing ontology and user profile at each different location.
