本論文提出一個方法,使移動式及靜止的agent攜帶更新的ontology,而ontology則以DAML描述。 這樣可使agent間以精確、穩定、快速及安全的方式來溝通。此外,agent可精確的存取DAML-enabled網站之資訊。 本文附Advanced Traveler Information Systems (ATIS)之範例,以展示本方法之優點。 This thesis presents a scheme for agents, mobile or stationary, to carry updated ontology in DARPA Agent Markup Language (DAML) so that agents can communicate with each other in a precise, stable, and secure way. Furthermore, agents can access information on DAML-enabled web sites. An example in Intelligent Transportation system (ITS) is included to depict the advantage of this scheme.
