Semantic similarity measures in ontology alignment

Numerous ontological or semantic similarity measures have been proposed to determine how similar one concept is to another within the context of an ontology. These measures are shown to have as their basis fuzzy set compatibility measures and have been used in a variety of biomedical and bioinformatics applications. In this paper a new matcher, the mediating matcher with semantic similarity (MMSS), has been designed in an adaptable manner and added to an existing OA system. Experiments are performed to compare the performance of several semantic similarity measures with different domain reference ontologies when used in the task of ontology alignment.
