Web information can be given more explicit meanings through semantic annotation, so that computer can understand and deal with the information automatically, which is important to improve recall ratio and precision ratio of search engine. An ontology-based semantic annotation method is represented in this paper, and which has been applied in an academic search. Construction of academic ontology, semantic annotation algorithm and semantic retrieval are described.
