Design of Semantic Information Systems using a Model-based Approach

The use of social and semantic technologies in business demands an optimal balance between business requirements and technological opportunities. Therefore, the usage of model-based approaches to pre-assess the added value of such semantic information systems is of high importance. In this paper we extend an e-business modeling framework to integrate business aspects with social interaction and semantic technologies. In particular we introduce two graphical model types for describing the interaction of users with semantic- enabled services and for visually representing ontologies.
