Understanding user requirement is an integral part of information system design and is critical to the success of interactive systems. It is now widely understood that successful systems and products begin with a clear understanding the domain of the system, and needs and requirements of the users. There are several purposes for modeling and analyzing the problem domain before starting the software requirement analysis. First it focuses on the problem domain so that the domain users could be involved easily. Secondly a comprehensive description on the problem domain will advantage getting a comprehensive software requirement model. This paper model an ontology based framework to satisfy the criteria mainly organizational structure, agent’s interaction, goal achievement. In this paper we show a very popular interactive system “Teleteaching” as the case study for the proposed framework.
