This paper presents an empirical simulation model for the frequency response of an eddy-current sensor to a distance measurement disturbed by target temperature variations. In previous papers [3, 4], we have shown that source separation [6, 2] could be a method to obtain a good distance measurement independently from temperature variations. The linearisation of the nonlinear frequency response of...
In this paper, we present an approach for high stake decision making based on the processing of uncontrolled knowledge originated from e-communities. Knowledge bases fed by such communities can provide a very rich source for a diagnosis or decision-support systems. However, they inherently bear inherent problems due in particular to knowledge heterogeneity, vagueness, completeness, uncertainty, and...
The main purpose of this paper is to present a new approach for High-Stake Decision Support Systems. We introduce the challenge of the exploitation of heterogeneous community-based knowledge for decision-aid in critical situations. Knowledge shared in e-communities can be very rich, but is also inherently chaotic and questionable. Such uncontrolled knowledge is not usually considered in High-Stake...
In this paper, we discuss the use of the Systems science, starting from the General Systems Theory, for Enterprise Interoperability (EI). We review and discuss main systemic concepts, highlighting the system properties that are important for interoperability and solutions to deal with related issues at a systemic level. We then propose an ontology, which grounds the existing Framework for Enterprise...
We present here a recommending system that has been developed for filtering TV content provided to mobile devices users. This recommender is fully based on ontologies, which are used to formalize both the user and her/his interests, and the audiovisual content. The developed ontologies allow matchmaking between user and content at different levels, based on three means to define user interests: according...
In this short paper, we present a series of ontologies allowing modeling of user, multimedia content and context, and a rule-based matchmaking approach for recommending systems. Category-based preferences as well as the expression of any interest concerning a concept formalized in an ontology are allowed. Furthermore, recommendations can be provided adequately in different situations as the user ontology...
This paper reports the implementation of the concepts of the reactive and adaptive multimedia object model (RAMO) via a guided review of its development process on a MPEG-4 rendering platform. The implementation of a simple iTV application is presented as well as a content animation engine. These activities have been achieved in the context of the ITEA Jules Verne project
