摘要：
The World Wide Web can be considered to be a huge semi-structured database that can provide us with a vast amount of information. Existing Web search techniques have significant deficiencies with respect to robustness, flexibility and precision. The purpose of this research is to develop a domain-centred alternative to keyword and subject directory search engines. The specific domain being considered for the prototype implementation is that of Australian universities including all the internal entities that belong to each university such as faculties, departments, research centres, etc. that is available on the Web. By modelling the ontology of this particular domain using an object-relational data model and restructuring the Web data using an object-relational database, structured queries can be issued against this database in a fashion that current search engines do not provide.
