Equalizing the structures of web communities in ontology development tools

In this paper we face some relevant issues on the relations between web communities and ontologies. We build an operator that constructs a weak Web Community, according to the definition given in [16],starting from a seed of web sites. The necessity of such an operator is derived from a problem arisen in the model developed in [3], in which some relevant concepts in automotive oriented ontology were not given a corresponding Web community. This fact –if not considered- can bring automatic ontology development ([9,18]) to some non-correct results. In this work we define and analyze a new operator, called Com, with the tools furnished by the method of parametrization ([8,15]) and we find that, given a seed S and the induced graph I(S), the community generated by our operator is monotonic with respect to clustering and is denser than the original graph I(S).
