Multi-sensor Information Fusion by Query Refinement

To support the retrieval and fusion of multimedia information from multiple real-time sources and databases, a novel approach for sensor-based query processing is described. The sensor dependency tree is used to facilitate query optimization. Through query refinement one or more sensor may provide feedback information to the other sensors. The approach is also applicable to evolutionary queries that change in time and/or space, depending upon the temporal/spatial coordinates of the query originator

Negotiations in spatial reasoning applications

This paper discusses how a visual language can be developed to assist the user in an interactive approach of horizontal and vertical reasoning for intelligent information retrieval. In addition, it discusses how negotiation can be performed with respect to the spatial and temporal applications, from computer science, cognitive and sociological viewpoints. It also forecasts the future evolution of web oriented meeting system. (3 refs.)Godkänd; 1997; 20080506 (andbra);ISBN för värdpublikation: 0-8186-8144-6</p

Reasoning with multimedia information using symbolic projection

In many multimedia application systems, it is not the final goal to retrieve the relevant multimedia information from different multimedia information sources. Rather, post-processing of the retrieved multimedia information is needed. For example, the retrieved information is used as &ldquo;known facts&rdquo;. The systems will do some reasoning to obtain further conclusions based on these multimedia form &ldquo;known facts&rdquo;. We call this reasoning with multimedia information. Most current research work in multimedia information processing is focused on multimedia information retrieval, but post-processing the retrieved information is more or less ignored. This paper explores the way to tackle this problem by using symbolic projection. A case study of reasoning with still image information is presented. Some extensions to symbolic projection- introducing auxiliary pictorial objects in symbolic pictures that need to be processed-are discussed. We expect this paper will stimulate further research on this important but ignored topic. <br /
