Abstract: This paper deals with a method, based on qualitative analysis, to write fuzzy controllers. Several qualitative controllers will first be analyzed. Then, the qualitative analysis will be used to explain the behaviour of existing fuzzy controllers. Finally, the method is applied to write fuzzy controllers automatically. Simulation results are provided for all types of controller.

Abstract: The aim of this paper is to describe the basic AI techniques in “linguistic knowledge processing”, a field that at temps to get machines to understand natural languages. In particular, we will focus on how computing techniques can model the communication process. We will therefore be interested in what the various levels of linguistic knowledge (apart from “phonetic” competence, which we choose to ignore) contribute to the understanding process - and how in turn, these types of knowledge (syntactic, semantic, and pragmatic) can be represented in formal computer applications that model human understanding. After some preliminary remarks about the …theoretical and practical importance of this field, the paper introduces firstly a sample of the theories used to represent linguistic knowledge (transformational, case, systemic and unification grammars). This will be followed by a presentation of semantic representations (various logics and semantic networks). A section on pragmatic aspects of communication (often called “discourse analysis”) will complete the theoretical presentation. The second part of the paper - “doing it on the computer” - begins with parsing systems, from morphological analysis via transition networks and lexicon driven analysers, to deterministic parsers. Each system, theory, or model has its own limitations. This poses great problems when faced with the need to integrate it into a unified procedural whole with other modules of the understanding process. Therefore, the final part of the paper adresses architectural issues. In particular, we show why we think that Distributed Artificial Intelligence and reflective systems offer the best framework to handle these problems. Examples taken from our own system (CARAMEL - acronym for “Compréhension Automatique de Récits, Apprentissage et Modélisation des Échanges Langagiers”) will illustrate this last point. Show more

Abstract: An important further development of model-based diagnosis systems are diagnosis/repair systems. These systems view the repair of a faulty system as the ultimate goal and therefore couple diagnosis tightly with repair in order to reduce the overall problem solving costs. In addition, such systems integrate the fields of diagnosis and planning representing two important areas of Artificial Intelligence. This paper describes the approach by Friedrich, Gottlob, and Nejdl in detail and surveys all major contributions to the area of diagnosis/repair systems.

Abstract: In this paper we investigate some of the uncounscious mechanisms underlying the process of acquisition of beliefs through perception. The paper outlines the basics of a formal theory of belief that is sensitive to the way in which beliefs are formed through perception. The process of belief acquisition involves a form of inference that is defeasible. We represent this kind of inference by means of well-known techniques of non-monotonic reasoning. In addition, we provide an account of perception that is consistent with the commonsense intuition for how perception functions, i.e., causality.
