An Ontology Based Approach for Satisfying User Requests in Context Aware Settings

In context aware settings, if one or more services are unavailable, it may be useful to look for a set of services whose combined effect would be functionally equivalent to a given request. We show that the notion of functional equivalence is quite useful in some real world scenarios. In this paper, we suggest a method to obtain a composed service whose effect is functionally equivalent to the given request. The algorithm has been implemented on some domains and the results are promising.
