INVOLVING WEB-TRADING AGENTS MAS: An Implementation for Searching and Recovering Environmental Information

摘要

The Web-based Information Systems appear to facilitate the access of user(s) to different kind of information geographically distributed in different regions (both data and users). In a web system, we have the possibility to use components called traders that improve the interoperability with agents or even trading systems. This paper describes details for a Web Trading Agent in a Multi-Agent System, which implements a distributed information system, called SOLERES. Besides, it presents the communication system based on ontologies through which the system agents communicate with each other and with the trading agent inside the SOLERES system (i.e., an Environmental Management System). This architecture is based on a "Query-Searching/Recovering-Response" model. For the implementation it uses: an interface user agent and the trader agent, "processes" ontologies for the agent communication, "data" ontologies for the information storage, SPARQL notation for queries and the JADE platform for the implementation.
