模糊时空XML数据Schema的研究

为了管理模糊时空XML数据,将若干个模糊构造子引入到XML文档中,并对XML文档的Schema进行模糊时空扩展,同时,通过修改XML文档的Schema以容纳这些新引入的模糊构造子.由此形式化提出模糊时空XML数据模型,之后分别对模糊时空XML数据模型中OID部分、ATTR部分、FP部分、FM部分以及FT部分的Schema进行扩展,并举出具体实例加以说明.通过对Schema的扩展,使其兼容模糊时空信息,方便管理模糊时空XML数据,从而可以进一步表示、推理和查询模糊时空XML数据.

Research on Schema of Fuzzy Spatiotemporal XML Data

In order to manage fuzzy spatiotemporal XML data， several fuzzy constructs are integrated in XML documents. Consequently， Schema of XML documents need to be fuzzy spatiotemporal extended. In the meantime， the integrated constructs should be compatible by modifying Schema of XML documents. Fuzzy spatiotemporal XML data model was formally proposed firstly. Subsequently， Schema of the OID part， the ATTR part， the FP part， the FM part， and the FT part in fuzzy spatiotemporal XML data model were extended， respectively. In succession， an example was introduced to give illustrations. After extending Schema， the XML documents were compatible with fuzzy spatiotemporal information， which was easy to manage fuzzy spatiotemporal XML data. What’s more， it could be further used for representing， reasoning， and querying fuzzy spatiotemporal XML data.
