Application of EQuA2te Architecture in Economic Intelligence

Abstract: Economic Intelligence can be considered as the use of information for strategic decision making. From this point of view, it can be considered as a process covering two established scientific domains: information systems and decision making. Moreover, Economic Intelligence concerns all socio-economic sectors and not restricted only to companies or industries. A system that combines the proposals in Information System Aided Decision Making and User Modelling is what we term Economic Intelligence System. This paper presents our work on the use of Information Systems as a component of Economic Intelligent System through the EQuA2te (Explore, Query, Analyse and Annotate) architecture. Our work started by the study of the student modelling in computer aided education in which we proposed a model based on the evocative habits of a learner. When used as a problem solving tool, an Information System Aided Decision Making is very similar to a computer aided education system as regards their cognitive functional characteristics. We also present the use of the EQuA2te architecture for managing the information base and the knowledge on the various actors. We conclude with a brief presentation on the various topics on which we are working as a continuation of the work presented here.

Modélisation de l'utilisateur, Systèmes d'Informations Stratégiques et Intelligence Economique

Abstract: Cet article presente le resultat des recherches menees par l'equipe SITE (Modelisation et Developpement de Systemes d'InTelligence Economique) du LORIA (Laboratoire Lorrain de Recherche en Informatique et ses Applications) dont l'objectif est d'etudier la modelisation et le developpement de systemes d'informations strategiques dans le cadre de l'Intelligence Economique (IE). Dans notre article, nous explicitons successivement la specificite des SIS par rapport aux SI classiques, quels sont les differents acteurs d'un SIS et comment prendre en compte l'acteur utilisateur du SIS par analogie a ce que l'on a deja mis en oeuvre dans un systeme de recherche d'informations (SRI). Nous developperons en particulier comment mettre en place des bases metiers «intelligents» et comment meta-modeliser un tel systeme d'information.

Plate-forme d'analyse morpho-syntaxique pour l'indexation automatique et la recherche d'information : de l'écrit vers la gestion des connaissances

Abstract: La contribution de ce travail de these s'inscrit au sein d'un domaine multidisciplinaire regroupant le traitement automatique du langage naturel, l'indexation dans un systeme d'information documentaire et l'organisation des connaissances autour de l'information ecrite. Sa particularite consiste en la mise a disposition d'outils pour le traitement automatique de l'information. L'objectif est de construire une Plate-forme d'analyse morpho-syntaxique pour l'indexation automatique et la recherche d'information. Elle est composee d'un noyau d'indexation automatique (processus d'indexation) qui utilise le modele des syntagmes nominaux comme descripteurs de l'information textuelle. Ces syntagmes sont organises selon une approche Logique Intensionnelle/Extensionnelle (processus de classification des connaissances) qui permet d'ordonner les objets d'une classe et de distinguer les classes de connaissances. A la base de cette derniere propriete, nous construisons notre approche pour la recherche d'information (processus de recherche d'information). Cette Plate-forme d'analyse dans sa logique de fonctionnement sera un outil d'investigation oriente vers l'organisation et la gestion des connaissances ecrites. Dans notre recherche, cet aspect sur l'organisation des connaissances a ete conduit dans le but de faire emerger les proprietes linguistiques et le traitement du langage dans une pratique experimentale sur l'indexation automatique documentaire. Nous avons montre la necessite de coordonner d'autres sources et strategies dans l'exploration de ces proprietes. Il s'agit du mode de raisonnement et de la technique d'exploitation des objets du discours specifiques a la gestion des connaissances (comme etape prealable a la recherche d'information). Ces deux derniers aspects (mode et technique) integres dans le processus de la presentation et de l'organisation du syntagme nominal offrent des scenarii pertinents pour la recherche d'informations.

A model of information retrieval problem in Economic Intelligence context

Abstract: The activity of watch within the process of Economic Intelligence (EI) is mainly an activity of resolution of information retrieval (IR) problem. This activity of watch is carried out in collaboration by the watcher who must locate, supervise, validate and emphasize strategic information, and by the decision maker who must formulate exact objectives for the decision-making. In order to optimize the sharing of knowledge between the decision maker and the watcher we tried to establish a model of IR problem. This model can help to increase the precision of the representation of the various parameters of the problem and to allow a greater performance of resolution and an optimization of the solution.

Contribution to the understanding of explanatory factors for the decision-maker problem within the framework of economic intelligence

Abstract: In an economic intelligence context, the decision-maker is more and more intersted in changes of him complex environment.To help him face these situations, we propose a decision-maker model based on a set of parameters that describe the decision-maker?s behavior as regards a problem. These parameters are related to the decision-maker as an individual, to the organization and the environment to which it belongs. The model of the decision-maker presented in this paper, thanks to its support for the decision-maker, allows the watcher to better understand a concrete problem posed by a given decision-maker and thus allows the watcher to seek for and to produce analyses of the most relevant information.

De l'élaboration d'un site web à l'extraction de données

Abstract: Cet article presente le resultat des recherches menees par la Societe NetLor-Concept en collaboration avec une equipe du LORIA. Il s'agit de faire migrer des bases de donnees d'anciens SGBD vers de nouveaux outils, avec comme objectif leur interrogation sur Internet. Dans un premier temps nous expliquons le contexte et le probleme pose, c'est a dire la retro conception de bases, puis nous donnons un exemple de ce que realise un des outils concus, enfin nous situons le contexte du projet de recherche appliquee. Une rapide explication de l'algorithme de classification sur lequel repose l'outil est donnee en annexe.

The content-based image retrieval as an assistance tool to the architectural design domain

Abstract: The architectural design requires a research of ideas and a documentation to help the designer in its creation work. It is a domain where the use of pictures (drawing, photography,...) is essential, because the information transmitted by photographic images are often more easily to understand than the one transmitted by texts. The goal of this work is to show the help that can bring the research of pictures indexed by visuals criteria, as colour, texture and shape, in the architectural design domain. If we accept the principle that " an image is better than 10000 words ", we can make the hypothesis that an image research indexed by visual criteria can bring a supplementary help to the designer when he tries to resolve design problems. We tested a research tool resting on image indexation with graphic attributes. Two types of corpora have been used. The first one contains images illustrating building products and the second one shows buildings or parts of buildings, which illustrate the wood architecture domain. The objective of this experiment is to evaluate the relevance of this type of image indexing according to identified users needs. We try to determine which type of visual criteria is the most appropriate to help the designer in the various phases of the design process.
