The semantic web uses ontologies to improve searching since ontologies provide a richer semantic model of content by expressing terms and relationships. However, a problem with the web is the large number of ontologies, which complicates searching. To maximize the capability of the search, the ontologies need to be combined to obtain complex answers. Usually, the ontologies are created without following any guidelines and, therefore, combining them is not a simple task, especially when ensuring a consistent result. We propose using meta-agents on top of software agents in a multi-agent system to resolve the use and the combination of multiple ontologies and to enable searching and reasoning. The software agents search for parts in the ontologies corresponding to the user-request and meta-agents combine the results from the agents. The meta-agents also partition the ontologies into consistent sets and then combine multiple ontologies into meaningful and logically consistent structures. For this purpose, we extend an existing mapping and alignment algorithm used for communication between agents. The use of multi-agents gives advantages since they provide a parallel approach and, thereby, efficiently handle large numbers of ontologies in order to accomplishtasks separately.
