Abstract

The Semantic Web needs methodologies to accomplish actual commitment on shared ontologies among different actors in play In this paper, we propose a machine learning approach to solve this issue relying on classified instance exchange and inductive reasoning This approach is based on the idea that, whenever two (or more) software entities need to align their ontologies (which amounts, from the point of view of each entity, to add one or more new concept definitions to its own ontology), it is possible to learn the new concept definitions starting from shared individuals (i.e individuals already described in terms of both ontologies, for which the entities have statements about classes and related properties); these individuals, arranged in two sets of positive and negative examples for the target definition, are used to solve a learning problem which as solution gives the definition of the target concept in terms of the ontology used for the learning process The method has been applied in a preliminary prototype for a small multi-agent scenario (where the two entities cited before are instantiated as two software agents) Following the prototype presentation, we report on the experimental results we obtained and then draw some conclusions.
