Particle swarm optimization for support vector clustering Separating hyper-plane of unlabeled data

International audienceThe objective of this work is to design a new method to solve the problem of integrating the Vapnik theory, as regards support vector machines, in the field of clustering data. For this we turned to bio-inspired meta-heuristics. Bio-inspired approaches aim to develop models resolving a class of problems by drawing on patterns of behavior developed in ethology. For instance, the Particle Swarm Optimization (PSO) is one of the latest and widely used methods in this regard. Inspired by this paradigm we propose a new method for clustering. The proposed method PSvmC ensures the best separation of the unlabeled data sets into two groups. It aims specifically to explore the basic principles of SVM and to combine it with the meta-heuristic of particle swarm optimization to resolve the clustering problem. Indeed, it makes a contribution in the field of analysis of multivariate data. Obtained results present groups as homogeneous as possible. Indeed, the intra-class value is more efficient when comparing it to those obtained by Hierarchical clustering, Simple K-means and EM algorithms for different database of benchmark

A Guidance Based Approach for Enhancing the e-Government Interoperability

Developing e-Government interoperability in the government context is a complex task. As interoperability in government context is associated and hindered by many challenges and barriers connected to government nature of complexity. Interoperability is generally defined as the ability for two (or more) systems to exchange information and to use the information that has been exchanged. In this paper, we focus on computing systems interoperability across government ministries to achieve interoperable e-Government IT based solutions. In order to achieve e-Government interoperability in an organised and efficient way, this paper establishes a guidance-based approach for enhancing the e-Government Interoperability. This contribution is motivated by the limitations of the traditional software engineering methodologies in terms of analysis, design and development frameworks to a point that they can hardly cope with the growing issues of e-Government services interoperability

Une approche centrée exigences pour la composition de services web

International audienceThis paper presents a requirement-centric approach for Web service composition which allows: (i) modeling users' requirements with the MAP formalism and specifying required services using an Intentional Service Model (ISM); (ii) discovering relevant Web services by querying the service search engine Service-Finder; (iii) selecting automatically relevant and high QoS services by applying Formal Concept Analysis (FCA); and (iv) generating automatically BPEL coordination processes by applying the model transformation technique. In this paper, we illustrate our approach with a conference arrangement application and we validate it empirically in terms of precision and recall on this application. MOTS-CLÉS : composition de services web, exigences des utilisateurs, QdS, AFC, transformation de modèles.Cet article présente une approche centrée exigences pour la composition de services web qui permet : (i) la modélisation des exigences des utilisateurs avec le formalisme la Carte et la spécification des services requis avec un modèle intentionnel de services (MIS) ; (ii) la découverte des services web pertinents en interrogeant le moteur de recherche de services Service-Finder ; (iii) la sélection automatique de services pertinents et de haute QdS par l'application de l'analyse formelle de concepts (AFC) ; et (iv) la génération automatique de processus de coordination BPEL par l'application de la technique de transformation de modèles. Dans cet article, nous illustrons notre approche par une application d'arrangement de conférences et nous la validons empiriquement en termes de précision et de rappel sur cette application

Alignment of viewpoint heterogeneous design models: Emergency Department Case Study

International audienceGenerally, various models can be used to describe a given application domain on different aspects and thus give rise to several views. To have a complete view of the application domain, heterogeneous models need to be unified, which is a hard task to do. To tackle this problem, we have proposed a method to relate partial models without combining them in a single model. In our approach, partial models are organized as a network of models through a virtual global model called M1C (Model of correspondences between models) which conforms to a ubiquitous language based on a Meta-Model of Correspondences (MMC). This paper presents an application of our method to an “Emergency Department” case study. It has been performed as a collaborative process involving model designers and a supervisor. The focus is put on the building of the M1C model from 3 partial models
