Passing from requirements specification to class model using application domain ontology

The quality of a classic software engineering process depends on the completeness of project documents and on the inter-phase consistency. In this paper, a method for passing from the requirement specification to the class model is proposed. First, a developer browses the text of the requirements, extracts the word sequences, and places them as terms into the glossary. Next, the internal ontology logic for the glossary needs to be elaborated. External ontology sources, as Wikipedia or domain ontology services, may be used to support this stage. At the end, the newly built ontology is transformed to the class model. The whole process may be supported with semi-automated, interactive tools. The result should be the class model with better completeness and consistency than using traditional methods.
