Dynamic Ontology Mapping (a first prototype)

Paolo Besana

Within a MAS, individual agents interact in order to perform set of given tasks; for example buying a product, retrive information, and so on. Open MAS place weaker constraints on the agents that can take part in the interactions: often it is not possible to ensure that all agents share the same ontology. Mapping in advance all the possible combinations of ontologies may not be feasible. My proposal is to model the dialogues, as they take place:  these models are used to increase the efficiency of standard ontology mapping methods. Mapping takes place when a new term appears in a received message, and the corresponding (or the closest) term in the agent's ontology is found. The model is used to predict the set of possible corresponding terms, reducing the number of computationally expensive comparisons between the received term and the terms in the agent's ontology.
