An Agent-based Search Engine based on the Internet Search Service on the CORBA

Search service is an important tool in the World Wide Web. In general, these standard web search engines are far from idea. Many researchers have therefore implemented Multi-Engine Search Service (MESS) using meta-broker. However these MESS are difficult to integrate a new search engine. On the other hand, the applications that need search service ability are also difficult using these MESS. In this paper, we propose an Internet Search Service (ISS) based on the CORBA. We follow the style of Common Object Service Specification to define the interface of ISS, so that it is not only easily to integrate any search engine into multi-search services, but also can be queried by application programs. In addition, two search engine agents are implemented in our project, one is for Yahoo and the other is for AltaVista. Programmers can use this interface to coding their search engine agent or to query search service in their applications. Finally, we build a heterogeneous search engine agent based on this
