TheÃ‚Â modularity indicates a one-to-one mapping between functional concepts and physicalÃ‚Â components. It can allow us to generate more product varietiesat lower costs. Functional concepts can be described by preciseÃ‚Â syntactic structures with functional terms. Different semantic measures can beÃ‚Â used to evaluate the strength of the semantic link betweenÃ‚Â two functional concepts from port ontology. In this paper, differentÃ‚Â methods of modularity based on ontology are first investigated. Secondly,Ã‚Â the primitive concepts are presented based on port ontology byÃ‚Â using natural language, and then their semantic synthesis is usedÃ‚Â to describe component ontology. The taxonomy of port-based ontology areÃ‚Â built to map the component connections and interactions in orderÃ‚Â to build functional blocks. Next, propose an approach to computingÃ‚Â semantic similarity by mapping terms to functional ontology and byÃ‚Â examining their relationships based on port ontology language. Furthermore, severalÃ‚Â modules are partitioned on the basis of similarity measures. TheÃ‚Â process of module construction is described and its elements areÃ‚Â related to the similarity values between concepts. Finally, a caseÃ‚Â is studied to show the efficiency of port ontology semanticÃ‚Â similarity for modular concept generation.
