TheÂ modularity indicates a one-to-one mapping between functional concepts and physicalÂ components. It can allow us to generate more product varietiesat lower costs. Functional concepts can be described by preciseÂ syntactic structures with functional terms. Different semantic measures can beÂ used to evaluate the strength of the semantic link betweenÂ two functional concepts from port ontology. In this paper, differentÂ methods of modularity based on ontology are first investigated. Secondly,Â the primitive concepts are presented based on port ontology byÂ using natural language, and then their semantic synthesis is usedÂ to describe component ontology. The taxonomy of port-based ontology areÂ built to map the component connections and interactions in orderÂ to build functional blocks. Next, propose an approach to computingÂ semantic similarity by mapping terms to functional ontology and byÂ examining their relationships based on port ontology language. Furthermore, severalÂ modules are partitioned on the basis of similarity measures. TheÂ process of module construction is described and its elements areÂ related to the similarity values between concepts. Finally, a caseÂ is studied to show the efficiency of port ontology semanticÂ similarity for modular concept generation.
