“…Knowing that some works propose to model spatio-temporal relations [9] Our system proposes also querying documents using SPARQL language which represent another way to query multimedia documents. For now, user could directly query documents via SAPRQL, but we will also adapt this language, in second step, for querying multimedia documents.…”

Manipulation of XML data is becoming increasingly important for multimedia retrieval. Several encouraging attempts at developing methods for searching data have been proposed. However, efficiency and simplicity are still a barrier for further development. This paper gives a global idea about our multimodal system for retrieval multimedia annotated documents. This system combines four retrieval modalities: first by keywords, second by visual graph, third Query by Resources and finally using standardized languages.

“…Liu and Wan (2010) propose a feature-based spatiotemporal data model and use the Native XML Database to store the spatiotemporal data. The work of Franceschet, Montanari, and Gubiani (2007) describes a translation algorithm that maps spatiotemporal conceptual schemas into XML schemas and proposes a framework that allows one to validate XML documents containing spatiotemporal information with respect to spatiotemporal conceptual schemas.…”

Because increasing requirements of fuzzy spatiotemporal applications are attracting much attention from both academia and industry, it is challenging to model fuzzy spatiotemporal data and effectively operate them. However, various researches are studied in traditional databases that impose strict restrictions, and relatively little work has been carried out in modeling and operating fuzzy spatiotemporal data in XML. In this paper, we propose a novel approach to model fuzzy spatiotemporal data based on XML. On the basis of the model, we investigate how to represent fuzzy spatiotemporal data in XML documents and extend the XML schema so that it is possible to describe fuzzy spatiotemporal data and capture the structural information of fuzzy spatiotemporal XML documents. Furthermore, we give algorithms for fuzzy operations, containing node operations and topological relationship operations. Finally, we apply our model in meteorological events.

A formal algebra is essential for applying standard database-style query optimization to XML queries. We develop such algebra for manipulating fuzzy spatiotemporal XML data. We also introduce several formal characterizations of fuzzy spatiotemporal algebraic equivalences and study how XQuery expressions can be transformed into algebraic expressions. It shows that the algebra can lay a firm foundation for managing fuzzy spatiotemporal XML data. INDEX TERMS Algebra, fuzzy spatiotemporal data, XML.
