摘 要 本論文提出在網際網路上,使用DAML (DARPA Agent Markup Language)來描述ontology,使移動式及靜止的agent,藉由DAML ontology從中做推理, 且DAML允許容易地更新ontology,使agent有智慧地互動來溝通。 Agent Gateway功能結合異質MAS,藉此跨異質系統功能提升agent資訊取得豐富性。 再配合無線通訊網路Mobile IP功能,使一個用路人的GPS功能成為「行動資訊加值服務」資訊系統,達到滿足用路人的各項需求。 Abstract This thesis uses DAML (DARPA Agent Markup Language) to describe ontology as mobile and stationary agent in internet. We could use DAML ontology to reason within. Because DAML allows easy ontology updates , Moreover, agents can infer from the DAML ontology and interact intelligently it make agent wisely intercommunicate. Agent Gateway’s function combines heterogeneity MAS, and uses cross heterogeneity system to improve the abundance of agent acquired Information. By adding wireless communication internet Mobile IP function, a driver’s GPS becomes a mobile information value-added service information system. It will satisfy the driver’s various needs.
