This paper mainly discusses the fuzzy extension to the data type representation mechanism of the existing XML schema and OWL. In accordance with the needs of practical application, we prompt a kind of fuzzy extension form to XML schema data typing and point out the limitations of OWL data typing. Furthermore, we mainly investigate the description logic playing as the underlining theory counterpart...
In the real world, human knowledge and natural language have a big deal of imprecision and uncertainty. Imprecision and uncertainty play in the semantic Web context, as well as to many applications that use description logics (DLs) to capture, represent and perform reasoning with domain knowledge. In this paper, a fuzzy extension of description logic language SI is presented, which combines vague...
The Semantic Web is expected to process concept knowledge and data information in an intelligent and automatic way. Recent research has shown that OWL has a serious limitation on data types; i.e., it does not support customized data types and customized data type predicates. Furthermore, it canpsilat process imprecise and uncertain information which widely exists in the Semantic Web and Ontology....
