| 摘 要： | 针对时空推理及信息查询中存在的时空模糊性问题,通过模糊隶属函数对模糊本体中的关系进行描述,在模糊本体5W2H语义概念模型的基础上,研究了模糊本体下的语义处理方法和推理机制,基于本体模型和规则模型探讨了模糊本体知识推理机的设计方法,并将上述研究应用于旅游景点信息领域,从而对时空推理查询及语义信息检索过程进行模拟验证。

| Abstract: | Aiming at the fuzzy problems in spa-temporal query and reasoning, this paper has described the relationships in fuzzy on-tology by using fuzzy membership function, and built the FGO-5W2HST model based on fuzzy ontology′s 5W2H semantic conceptual model, Studies the semantic processing method and fuzzy ontology reasoning mechanism, model and rule model based on ontology dis-cussed the design method of fuzzy ontology knowledge reasoning machine.Finally test the process of reasoning query by simulative ex-amples in the field of tour scenery information. |
