“…It is composed of about 90 tables, with data extracted from about 700 microbiological publications. The conceptual graph subsystem has been implemented in C++ under Linux; it is composed of a 5.000-line extension of the CoGITaNT platform (Genest and Salvat, 1998). The conceptual graph database contains about 150 conceptual graphs.…”

Abstract.We present an information system developed to help assessing the microbiological risk in food. That information system contains experimental results in microbiology, mainly extracted from scientific publications. The increasing amount of the experimental results available and the difficulty to integrate them into a classic relational database schema led us to design a system composed of two distinct subsystems queried through a common interface. The first subsystem is a classic relational database. The second subsystem is a database containing weakly-structured pieces of information expressed in terms of conceptual graphs. The data stored in both bases can be fuzzy ones in order to take into account the specificities of the biological information. The uniform query language used on both relational database and conceptual graph database allows the users to express preferences by using fuzzy sets in their queries. The MIEL system is now operational and used by the microbiologists involved in the Sym'Previus French project.

This paper introduces a novel approach to assist the author during the production process of new audiovisual documents from audiovisual archives. Our research relies on rhetorical tradition to relate author's intentions to forms and contents of target audiovisual discourse. We present the different levels of structure which are involved in the authoring process, together with their associated components (topic structure, intentional discourse structure, concrete discourse structure, discursive and narrative components). The paper specially focuses on reuse of audiovisual resources and shows how the context of their indexation can be articulated with the new publication context, so emphasizing the interest of multiple discursive structures interaction. We illustrate our approach with an example of TV news publication based on political TV archives.

Abstract.One of the most rapidly evolving e-services is e-Learning, that is, the creation of advanced educational resources that are accessible on-line and, potentially, offer numerous advantages over the traditional ones like intelligent access, interoperability between two or more educational resources and adaptation to the user. The driving force behind these approaches is the definition of the various standards about educational metadata, that is, data describing learning resources, the learner, assessment results, etc. The internal details of systems that utilize these metadata is an open issue since these efforts are primarily dealing with "what" and not "how". Under the light of these emerging efforts, we present CG-PerLS, a knowledge based approach for organizing and accessing educational resources. CG-PerLS is a model of a web portal for learning objects that encodes the educational metadata in the Conceptual Graph knowledge representation formalism, and uses related inference techniques to provide advanced functionality. The model allows learning resource creators to manifest their material and client-side learners to access these resources in a way tailored to their individual profile and educational needs. IntroductionAs the World Wide Web matures, an initial vision of using it as a universal medium for educational resources is, day by day, becoming reality. There is already a large amount of instructional material on-line, most of it in the form of multimedia HTML documents, some of which are enriched with Java technologies. Unfortunately, most of these approaches have been built on general purpose standards and fail to utilize Web's potential for distributed educational resources that are easily located and interoperate with each other. 202Fotios Kokkoras et al.Information technology assisted education has reached sophisticated levels during 90's, taking into account issues like pedagogy, individual learner and interface, apart from the basic educational material organization. Following the recent "e-" trend, these approaches are just beginning to appear on the internet. The reason for this late adoption is mainly the substantial effort that is required to bring them on the Web since all of them have been designed without the Web in mind.On the other hand, it is commonplace that our society has already moved away from the "once for life" educational model. The complexity and continuous evolution of modern enterprises' activities requires continuous training of their personnel. The networked community enables the management and enhancement of knowledge in a centralized -yet personal way, while keeping track and merging new intellectual resources into that process. The above requirements and advances lead us to the "Lifelong Learning" concept. The idea is to integrate the WWW technology with a novel, dynamic and adaptive educational model for continuous learning. The result will be a learning environment that will enable the individual learner to acquire knowledge just-in-time, anytime and anywhere, ...
