关键字：Fuzzy spatiotemporal data XML document Consistency

摘要：Researches on spatiotemporal data based on XML has received increasing attention due to that XML has a lot of advantages such as extensibility and flexibility. Although XML has been employed to model and handle spatiotemporal data, relatively little work has been carried out to further investigate the consistencies of spatiotemporal data, especially fuzzy spatiotemporal data in XML documents. In this paper, we first propose a fuzzy spatiotemporal data model, and then present the structure of fuzzy spatiotemporal data in XML document. After studying consistency conditions for fuzzy spatiotemporal data in XML documents, we demonstrate how updating operations, inserting operations, and deleting operations effect on consistencies of fuzzy spatiotemporal data in XML documents. Furthermore, we propose algorithms for fixing these inconsistencies. After investigating several characteristics of the three primitive changing operations on the fuzzy spatiotemporal data model, the performances of inconsistency fixing time are evaluated.
