Service discovery platform for ubiquitous environments

The capability to easily find useful services in ubiquitous environments becomes increasingly critical in several application domains. Current approaches for ubiquitous services retrieval are mostly limited to the matching of their inputs/outputs possibly enhanced with some ontological knowledge. Recent research has demonstrated that this approach is not sufficient to discover relevant services. Motivated by these concerns, this work proposes a service discovery platform in ubiquitous environments based on behavior matchmaking. We argue that in many situations the service composition process requires a service discovery phase based on matchmaking of behavior specifications of the components. Consequently, even if a service that meets exactly the user requirements does not exist, the most similar ones will be retrieved.
