CORE: A Tool for Collaborative Ontology Reuse and Evaluation

Ontology evaluation can be defined as assessing the quality and the adequacy of an ontology for being used in a specific context, for a specific goal. In this work, a tool for Collaborative Ontol- ogy Reuse and Evaluation (CORE) is presented. The system receives an informal description of a semantic domain and de- termines which ontologies, from an ontology repository, are the most appropriate to describe the given domain. For this task, the environment is divided into three main modules. The first com- ponent receives the problem description represented as a set of terms and allows the user to refine and enlarge it using Word- Net. The second module applies multiple automatic criteria to evaluate the ontologies of the repository and determine which ones fit best the problem description. A ranked list of ontologies is returned for each criterion, and the lists are combined by means of rank fusion techniques that combine the selected crite- ria. A third component of the system uses manual user evalua- tions of the ontologies in order to incorporate a human, collabo- rative assessment of the quality of ontologies.
