Integrating Ontologies in Mobile Agents

The process of information extraction and data integration in a global information system demands automatic techniques for quickly determining semantic similarity among concepts across different ontologies. This paper presents a graph based approach for computing, on-the-fly, semantic similarities among ontologies of a specific domain. The approach consists of integrating mobile agents and ontologies to support a variety of applications in distributed environments. The resulting technique is illustrated on Hermes, agent-based middleware for mobile computing, by an example in molecular biology domain.
