碩士 === 國立交通大學 === 資訊科學系 === 87 === Search service is an important tool in the World Wide Web. Currently there are thousands of search engines on the WWW, each has different interface and characteristic. Since single search engine is far from idea, we have to integrate these heterogeneous search engines. Though there are Multi-Engine Search Service (MESS) using meta-broker to implement at present, an unified interface is still missing. Therefore these MESSs are difficult to integrate a new search engine, and the applications that need search service ability are also difficult to use these MESSs. In this thesis, we propose an Internet Search Service (ISS) based on the Common Object Request Broker Architecture that is an industrial standard of distributed object oriented platform and is announced by OMG. We follow the style of Common Object Service Specification to define the interface of ISS, so that it is not only easy to integrate any new search engine into multi-search services, but also can be queried by application programs. In addition, two agents are implemented in this thesis, one is for Yahoo and the other is for Alta Vista. Because the personalized information is much desirable, in this thesis, we propose a Personal Information Filtering Agent (PIFA) for WWW users. The architecture of the agent is composed of three level of information filtering mechanism. Final, we integrate ISS with PIFA to become a fully personalized search service system.
