| 摘 要： | 针对传统的基于关键词信息检索方式存在的问题，提出一种基于领域本体的语义检索模型，在建立本体概念与文档内容关联关系的基础上，对用户的查询输入预处理，利用本体计算两者的相似程度，给出与查询请求相关的排序后的文档。通过搭建基于本体的Web智能检索原型系统，验证了该模型的有效性。

| Abstract: | Aiming at the problem of traditional information retrieval based on key words, a domain ontology-based semantic information retrieval model is proposed. On the basis of establishing the relationship between the ontology concept and the content of document, pre-processes the user's query, calculates the similarity using domain ontology, and shows the sorted relative documents corresponding to the query. The built Web-based intelligent retrieval prototype validates the effectiveness of the model preliminarily. |
