Abstract

International audience; The problem of how to provide transparent access to heterogeneous information sources while maintaining their autonomy already appeared decades ago and has been addressed by data integration techniques. Those techniques enable the interaction between clients and data sources through a centralized access point, and uniform query interfaces that give users the illusion of querying a homogeneous system. However, they work under certain hypotheses, including moderately static scenarios, shared understanding of the domain of interest (in the form of a global schema or ontology), and a closed, or at least access-controlled, set of participating sources. All these hypotheses do not hold anymore in the current web comprising millions of autonomous peers, having no centralized control. In such an environment, research is needed to discover techniques for schema matching, mapping discovery, query processing, quality and trust management in such environments.

Abstract

In many important applications, the search for non-standard data types is essential. E.g., digital libraries and multimedia database systems offer content-based search functionality for images and 3D documents. Contrary to the annotation-based approach, where information manually attached to the data objects if used for retrieval, in content-based retrieval, automatically derived meta-data is used. However, the quality of the meta data is crucial, and often, it a priori is not clear which meta data is best suited to execute a user-issued query. Owing to the multi-meta data problem, two crucial questions arise: (a) how can different meta data (feature vector) schemas be benchmarked to assess their suitability for solving the retrieval problem effectively, and (b) how to support the user with issuing queries to the retrieval system, considering different choices for the type of meta data to engage in the search. In this paper, we address these questions in a two-fold contribution. Based on the DARE visualization system, we first introduce an approach for the visual benchmarking of multiple meta data formats on a ground truth benchmark, supporting the optimization stage of the multimedia database design. We secondly propose a simple, yet effective visual interface to multiple, long lists (rankings) of answer objects for the user. The latter, based on relevance feedback information supplied by the user, allows the effective identification of the meta data schema best suited for executing the similarity queries at hand.

Abstract

We introduce a novel view on how to deal with the problems of semantic interoperability in distributed systems. This view is based on the concept of emergent semantics, which sees both the representation of semantics and the discovery of the proper interpretation of symbols as the result of a self-organizing process performed by distributed agents exchanging symbols and having utilities dependent on the proper interpretation of the symbols. This is a complex systems perspective on the problem of dealing with semantics. We highlight some of the distinctive features of our vision and point out preliminary examples of its application.
