摘要: 为了实现语义Web中模糊时空知识的表示与推理,提出了一种支持模糊时空具体域的模糊描述逻辑F-ALCT(Dfst).首先,构建了包含模糊时空区域及其时空拓扑谓词的模糊时空具体域Dfst,给出了两个模糊时空区域之间的拓扑关系模糊度的计算方法.然后,将Dfst和时态操作符引入到模糊描述逻辑Fuzzy-ALC中,构建出一种新的模糊描述逻辑F-ALCT(Dfst),并定义了其语法、语义和知识库.最后,给出了一个F-ALCT(Dfst)的知识库实例.F-ALCT(Dfst)有效地实现了语义Web中模糊时空知识的表示.

Abstract: In order to achieve representation and reasoning of fuzzy spatio-temporal knowledge in semantic Web, a fuzzy description logic F-ALCT(Dfst) supporting fuzzy spatio-temporal concrete domain was proposed. Firstly, a fuzzy spatio-temporal concrete domain D○fst containing fuzzy spatio-temporal regions and their topological predicates was constructed. And the quantitative computation method of fuzzy topological relationships between fuzzy spatio-temporal regions was presented. Then, the concrete domain D○fst and temporal operators were introduced to fuzzy description logic Fuzzy-ALC, and a new fuzzy spatio-temporal description logic, called F-ALCT(Dfst), was proposed. Furthermore, a formal definition of syntax, semantics and knowledge base of the F-ALCT(Dfst) was presented. Finally, an example of F-ALCT(Dfst) knowledge base was given. The F-ALCT(Dfst) effectively realizes the representation of fuzzy spatio-temporal knowledge in semantic Web.

Key words: semantic Web, fuzzy description logic, fuzzy spatio-temporal regions, topological predicates, concrete domain, fuzzy spatio-temporal description logic
