Analysing the Use of Ontologies Based on Usage Network

In recent years, there has been a tremendous growth in Semantic Web data on the Web being annotated using Web ontologies. The use of Web ontologies by different data publishers is transforming the Web into a decentralized knowledge platform. To capitalize on structured and semantically rich data, we need to understand how these ontologies are being used. In this paper, to analyse the usage of ontologies by data publishers, we model ontology usage as an Ontology Usage Network. The Ontology Usage Network, which is a bipartite affiliation network, is used to study statistical and structural properties such as degree distribution, centrality measures and identification of cohesive subgroups. Finally, we present the analysis results and their interpretation.
