L’amour aux temps d’Internet : raison et émotion dans la recherche de partenaire en ligne des Chiliens
2017
This study analyzes the pages of online dating, more specifically, the interpretation that Chilean surfers perform these virtual spaces; interactions that occur within these web portals; and the sense that national users associate with their interactions. To answer these objectives not only a number of methods of collection and analysis of information is used, but in turn, the data generated is inserted in a wide theoretical discussion about love and relationships. Thus, in the first part of this work, the imagery of love is analyzed from its main myths and stories. Subsequently the historical and sociological constitution of relationships is analyzed. Epistemological, methodological and et…
Reconstruction et analyse sémantique de chronologies cybercriminelles
2014
International audience; La reconstruction de scénarios est l’une des étapes les plus importantes d’une investigation numérique. Elle permet aux enquêteurs d’avoir une vue des évènements survenus durant un incident. La reconstruction de scénarios est une tâche complexe requérant l’étude d’un très grand nombre d’évènements en raison de l’omniprésence des nouvelles technologies dans notre quotidien. De plus, les conclusions produites se doivent de respecter les critères fixés par la justice. Afin de répondre à ces challenges, nous proposons une nouvelle méthodologie, basée sur une ontologie intégrant les connaissances d’experts des domaines de la criminalistique et de l’ingénierie logicielle, …
De la scène de crime aux connaissances : représentation d'évènements et peuplement d'ontologie appliqués au domaine de la criminalistique informatique
2015
International audience; Avec la démocratisation des technologies, les enquêtes de criminalistique informatique impliquent des volumes de données toujours plus grands et hétérogènes. Pour faciliter le travail des enquêteurs, nos travaux ont pour objectif de reconstruire automatiquement les évènements liés à un incident numérique, tout en respectant les exigences légales. Pour cela, il est nécessaire d'introduire un modèle de représentation de connaissances permettant de structurer les informations recueillies sur une scène de crime dans le but de faciliter l'utilisation de processus d'analyse automatisés. Ce papier propose un état de l'art des modèles de représentations d'évènements pour le …
ACTIVE3D: SEMANTIC AND MULTIMEDIA MERGING FOR FACILITY MANAGEMENT
2010
International audience; This paper presents a Semantic Web approach for facility management. This Web-based platform lets geographically dispersed project participants--from facility managers and architects to electricians to plumbers--directly use and exchange project documents in a centralized virtual environment using a simple Web browser. A 3D visualization lets participants move around in the building being designed and obtain information about the objects that compose it. This approach is based on a semantic model called CDMF and IFC 2x3. CDMF improves data management during the lifecycle of a building. Based on graph combinations and the contextual element SystemGraph, our propositio…
Contribution of Semantic Web on Customer Relationship Management in E-Tourism
2010
International audience; This paper presents an ongoing research on the development of a customer relationship management in e-tourism. Based both on techniques of the Semantic Web and Adaptive Hypermedia Systems, this paper presents a solution for dynamic adaptation of the offer to customers according to semantic criteria characterizing the Internet. A case study about tourism in Côte d'Or department in Burgundy is presented.
AN ONTOLOGY-BASED APPROACH TO PROVIDE PERSONNALIZED RECOMMENDATIONS USING A STOCHASTIC ALGORITHM
2011
International audience; The use of personalized recommender systems to assist users in the selection of products is becoming more and more popular and wide-spread. The purpose of a recommender system is to provide the most suitable items from an knowledge base, according the user knowledge, tastes, interests, ... These items are generally proposed as ordered lists. In this article, we propose to combine works from adaptive hypermedia systems, semantic web and combinatory to create a new kind of recommender systems suggesting combinations of items corresponding to the user.
INCONSISTENCY IDENTIFICATION IN DYNAMIC ONTOLOGIES BASED ON MODEL CHECKING
2012
International audience; The increasing use of ontologies and the cost of changes support the need to manage the evolution of ontologies. A common kind of error in ontology evolution is the logical contradiction declined as incoherences and inconsistences. In this paper, we propose a new approach to predict and identify the incoherences and inconsistences in the evolution of ontologies based on temporal logic and ontology design patterns. We implement the proposed approach using the NuSMV model checker. Based on these patterns, we propose an automated process to guide and monitor the implementation of change while ensuring the consistency of the evolved ontology.
Temporal Semantic Centrality for the Analysis of Communication Networks
2012
National audience; De nos jours, la compréhension des communautés en ligne devient un enjeu majeur du Web. Dans cet article nous proposons une nouvelle mesure, la Probabilité de Propagation Sémantique (SPP), qui caractérise la capacité de l'utilisateur à propager un concept sémantique à d'autres utilisateurs, d'une manière rapide et ciblée. La sémantique des messages est analysée selon une ontologie donnée. Nous utilisons cette mesure pour obtenir la Centralité Sémantique Temporelle (TSC) d'un utilisateur dans une communauté. Nous proposons et évaluons une expérimentation de cette mesure, en utilisant une ontologie et des données réelles issues du Web.
COBieOWL, an OWL ontology based on COBie standard
2015
International audience; Building Information Modelling (BIM) standards have been recognized by construction and political actors as a highly promising tool for resolving issues of data dematerialization, notably in the field of Architecture, Engineering, Construction and Facility Management. Among worldwide-adopted BIM standards, there is COBie. COBie’s goals are to dematerialize building data and to enhance building information interoperability. Nevertheless, COBie data is available in static formats such as STEP or spreadsheet templates. Such formats lack logical formalisms and semantic features provided by languages such as OWL. Because of this, in this paper, we propose a method for sem…
Temporal Logic To Query Semantic Graphs Using The Model Checking Method
2012
International audience; Semantic interoperability problems have found their solutions due to the use of languages and techniques from the Semantic Web. The proliferations of ontologies and meta-information have improved the understanding of information and the relevance of search engine responses. However, the construction of semantic graphs is a source of numerous errors of interpretation or modeling, and scalability remains a major problem. The processing of large semantic graphs is a limit to the use of semantics in current information systems. The work presented in this paper is part of a new research at the border of two areas: the semantic web and the model checking. This line of rese…
