隨著 multi-agent 技術逐漸成熟,可預見將有越來越多 multi-agent systems 提供各種 domain services. 而這些分散的 agent services 若能 seamless 整合,除了能補足彼此的不足,還能提供使用者更完善的 services. 但要讓這些分散、異質的 MASs 能夠 interoperate, 必須要有一個能夠整合異質 MASs, 並提供 semantic interoperability 和 matching service 的系統。本文即建構一個 Multi-Agent Gateway System,能整合異質的 MASs, 並利用 Ontology Management System 提供 semantic interoperability 和 service identification 的機制,讓異質 MASs 可 interoperate, 共享彼此的 services, 形成一個 MASs federation, 提供多元服務。 本研究預期的優點是:1) Semantic translation of content,2) non-FIPA compliant MAS supports 和 3) Reliable service identification。 This work presents the Multi-Agent Gateway System (MAGS) to improve multi-agent system (MAS) interoperability. It employs ontology management system and its inference ability to assist semantic translation of message content. Also, it uses Java management extensions to manage and integrate heterogeneous MASs. Besides, the agent service description is provided to support service matching. An example is included that facilitates interoperation among several MASs, solving an ontology mismatch problem. The MAGS can: 1) deal with different content languages, and apply semantic translation of content. This achieves semantic compatibility. 2) support non-FIPA compliant MASs, and makes them interoperate with FIPA compliant MASs. 3) supply reliable service identification.
