Abstract: Technologies of semantic Web search are very novel and young. There are many theories and approaches contributed to semantic Web search, such as ontologies, information retrieval, natural language processing, and so on. Situadons of semantic Web and semantic Web search were introduced dividually. hhen, the general architecture of semantic Web search engine was concluded through analyzing research at home and abroad in detail. This architecture is composed of four models, including information extraction models, intelligent interface models, information query models,and user query models. The functions, technologies, and evaluation systems of models which arc different components of this general architecture were introduced in further. At last, the conclusion about our work was given. At the same time,the future challenge of semantic Web search technologies was discussed.
