This document describes concepts and tools that we have developed for the program supervision task. The first part is a reference manual, which introduces the concepts involved in this task as well as the proposed knowledge language and inference engine to achieve this task. The second part is a user's manual, which details both the Yakl...
In recent years, programs and knowledge about programs have become an important part of the "patrimony" (or intellectual property) of companies. However, the scope of this knowledge is wider than the simple code sources. In order to manage this knowledge it is necessary to model it. We propose a novel framework to encompass such knowledge. In...

We propose to use Artificial Intelligence techniques to monitor and control complex processing chains of software components. We consider software systems that run in an evolving environment and thus may require adaptation at run time. Our approach relies on knowledge representations of both structural and dynamic aspects of components and...
Détecter automatiquement et de manière précoce des bioagresseurs dans les cultures sous serre sans pesticides, tel est le défi dont nous parle Sabine Moisan.
This document briefly describes FrameLib, a C++ library to manipulate "frames" as they are used in the Artificial Intelligence world. The library provides a general framework (!) for creating new frames (!!) by inheritance. The intended use is to generate new frames automatically, from a frame description language. But nothing prevents from...
Cet article présente une expérience d'ingénierie des connaissances réalisée sur une utilisation avancée des codes de calcul : le calage de modèles numériques. Les connaissances associées à cette tâche ont été modélisées grâce à un langage de représentation de connaissances développé pour une tâche voisine : le pilotage de programmes. Après une...
This article is concerned with the on-line counting of some harmful insects in videos in the framework of in situ video-surveillance that aims at the early detection of pest attacks in greenhouse crops. The challenges mainly concern the tiny resolution and color contrast of the insects of interest in the videos, the outdoor issues and the...
Model calibration requires an evaluation of the agreement between model outputs and reference data. This article presents an automatic fuzzy knowledge-based approach to identify the relevant discrepancies. This evaluation module is intended to be integrated within an existing knowledge-based calibration support system.

This paper proposes an approach to the management and utilization of codes viewed as systems. This approach takes into account the whole "continuum" that exists from the knowledge of experts, computer scientists to the users of the codes: i.e., scientific, business, experimental, etc. knowledge. We define a referential for code management, from...
This paper deals with dynamic adaption of software architecture in response to context changes. In the line of "models at run time", we keep a model of the system and its context in parallel with the running system itself. We adopted an enriched Feature Model approach to express the variability of the architecture as well as of the context. A...

BLOCKS is an answer to the software engineering needs of the design of knowledge-based system engines. It is a framework composed of reusable and adaptable software components. However , its safe and correct use is complex and we supply formal models and associated tools to assist using it. These models and tools are based on behavioral...
