Ontology Mapping: As a Binary Classification Problem

Ontology mapping seeks to find semantic correspondences between similar elements of different ontologies. Ontology mapping is critical to achieve semantic interoperability in the WWW. To solve the ontology mapping problem, this paper proposes a non-instance learning-based approach that transforms the ontology mapping problem to a binary classification problem and utilizes machine learning techniques as a solution. Same as other machine learning based approaches, a number of features (i.e., linguistic, structural and web features)are generated for each mapping candidate. However, in contrast to other learning-based mapping approaches, the features proposed in our approach are generic and do not rely on the existence and sufficiency of instances. Therefore our approach can be generalized to different domains without extra training efforts. To evaluate our approach, two experiments (i.e., within-task vs. cross-task) are implemented and the SVM algorithm is applied.Experimental results show that our non-instance learning-based ontology mapping approach performs well on most of OAEI benchmark tests when training and testing on the same mapping task; and the results of approach vary according to the likelihood of training data and testing data when training and testing on different mapping tasks.
