Intégration du profil utilisateur basé sur les ontologies dans la reformulation des requêtes Arabes. 2ème Colloque pour les étudiants chercheurs en traitement automatique du langage naturel et ses applications (CECTAL), mars , 2015, Colloque, Sousse, Tunisie
    Abstract
    Le but de cet article est de présenter le système AXON dédié pour la Recherche d’Information Personnalisée (RIP) et destiné pour les utilisateurs actant en langue Arabe. Dans ce contexte, nous allons présenter une méthode d’expansion de requêtes en langue Arabe et qui exploite deux techniques: la première se base sur l’expansion de requêtes et utilise les ontologies dans le but d’enrichir les requêtes exprimées par l’utilisateur. La deuxième technique s’articule autour du profil utilisateur basé sur une approche hybride (représentation sémantique et multidimensionnelle) dans l’objectif d’adapter le processus de recherche aux besoins et intérêts de chaque utilisateur. La méthode d’expansion proposée a été implémentée et expérimentée sur 150 requêtes pour 50 utilisateurs.

    Abstract

    This paper deals with organizational perspective mining in workflow. First, it exposes a comparative study of three representative workflow mining systems: InWolve, WorkflowMiner and ProM. To perform our comparative study, we propose the following quality criteria: the capacity to filter and to convert an events log, the capacity to discover workflow perspectives and the capacity to support their analysis. The main limit of these systems is their inability to deal with organizational perspective mining issue. By organizational perspective, we mean, the social structures defining the activity distribution among actors involved in the workflow (namely federation, coalition, market or hierarchy), as well as the interaction protocols ruling the communications between them (such as contract net, auction or vote). To compensate the previous drawback, the paper proposes an agent oriented approach to support the organizational perspective mining. More precisely, it proposes an events log model, which extends existing models by taking into account the interactions among actors thanks to the performative-based agent communication language FIPA-ACL. It also presents a concrete case study to better illustrate the organizational perspective mining and some algorithms for organizational structures and interaction protocols mining. Finally, we describe in details our discopflow tool to validate our solution

International Conference on Information Systems and Economic Intelligence (SIIE), février, 2015, Conference, Nabeul, Tunisie
    Abstract

    The work presented in this paper aims to develop a system for information retrieval which has the particularity of being adapted to the Arabic language and providing personalized results based on the user's preferences / interests. For this reason, we proposed a query expansion method based on both semantic knowledge from existing ontologies for the Arabic language and information from the users’ profiles. The proposed method is interesting for several reasons. Personalized information related to the users’ profiles to enrich the query should be considered since it is entirely appropriate and justified to improve traditional IR systems. Moreover, this idea has been little exploited for IR systems in Arabic. In addition, the coupling between information from the user's profiles and that contained in the ontologies is also an original and interesting track to develop. The suggested query expansion method has been implemented and tested on 150 queries for 50 users or 7500 queries of evaluation. The results of this evaluation are promising.

    Abstract
    
    
    We proposed, in previous works, a business process execution language for data-driven workflow modeling, verification, and execution; the proposed model can present both control flow and shared data in workflow processes. It can be analyzed to verify its correctness before its deployment. In this paper, we are going to improve the semantics of our approach to allow a better integration between data and control flow, and between the workflow and its external environment (such as relational databases and XML documents). We are also going to extend our approach to generate multidimensional data models, namely OLAP hypercubes, from data handled by the workflow, in order to provide synthetic view of data for decision makers.

Abstract The Bayesian Networks are graphical models that are easy to interpret and update. These models are useful if the knowledge is uncertain, but they lack some means to express ambiguity. To face this problem, we propose Fuzzy Evidence in Bayesian Networks and combine the Fuzzy Logic and Bayesian Network. This has allowed to benefit from mutual advantages of these two approaches, and to overcome the problem of data and observation ambiguity. This paper proposes an inference algorithm which uses the Bayesian Network and Fuzzy Logic reliability. This solution has been implemented, tested and evaluated in comparison with the existing methods.

Description Ontologies and formal representations of knowledge are extremely powerful tools for modeling and managing large applications in several domains ranging from knowledge engineering, to data mining, to the semantic web. Ontology Theory, Management and Design: Advanced Tools and Models, explores the wide range of applications for ontologies, while providing a complete view of the both the theory behind the design and the problems posed by the practical development and use of ontologies. This reference presents an in-depth and forward looking analysis of current research, illustrating the importance of this field and pointing toward to the future of knowledge engineering, management and information technology.
