Abstract

Researches on spatiotemporal data based on the Resource Description Framework (RDF) have received increasing attention owing to that RDF has a lot of advantages such as extensibility and flexibility. At the same time, the works for uncertain data based on RDF have been extensively studied because of imprecision and uncertainty of data in many real-world applications. Although RDF has been employed to model and handle spatiotemporal data and uncertain data respectively, relatively little work has been carried out to further investigate spatiotemporal data with uncertainty, especially the consistencies of uncertain spatiotemporal data in RDF graphs. In this paper, we first propose an uncertain spatiotemporal data model and define the corresponding constraint framework for the model, then study the types of inconsistencies for uncertain spatiotemporal data in RDF graphs. On this basis, we present the methods for fixing the inconsistencies in the uncertain spatiotemporal RDF graphs caused by updating operations, inserting operations, and deleting operations.
