基于模糊本体的时空推理查询方法研究

摘要

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.%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。
