Ontology-based Integration of Web Navigation for Dynamic User Profiling
2015
The development of technology for handling information on a Big Data-scale is a buzzing topic of current research. Indeed, improved techniques for knowledge discovery are crucial for scientific and economic exploitation of large-scale raw data. In research collaboration with an industrial actor, we explore the applicability of ontology-based knowledge extraction and representation for today's biggest source of large-scale data, the Web. The goal is to develop a profiling application, based on the implicit information that every user leaves while navigating the online, with the goal to identify and model preferences and interests in a detailed user profile. This includes the identification o…
Adding Semantic Extension to Wikis for Enhancing Cultural Heritage Applications
2011
International audience; Wikis are appropriate systems for community-authored content. In the past few years, they show that are particularly suitable for collaborative works in cultural heritage. In this paper, we highlight how wikis can be relevant solutions for building cooperative applications in domains characterized by a rapid evolution of knowledge. We will point out the capabilities of semantic extension to provide better quality of content, to improve searching, to support complex queries and finally to carry out di fferent type of users. We describe the CARE project and explain the conceptual modeling approach. We detail the architecture of WikiBridge, a semantic wiki which allows …
Semantic Trajectory Modeling for Dynamic Built Environments
2017
This paper presents a data model to capture moving and changing objects in the context of dynamic built environment. Building elements are subject to change which represents semantic trajectories crossing trajectories of users. These semantic trajectories in dynamics built environment permit to capture fine-grained activities and behaviors of users and objects. The data model is based on ontology and description logics to capture logic constraints on semantic trajectories.
Semantic Mappings in Description Logics for Spatio-temporal Database Schema Integration
2005
International audience; The interoperability problem arises in heterogeneous systems where different data sources coexist and there is a need for meaningful information sharing. One of the most representive realms of diversity of data representation is the spatio-temporal domain. Spatio-temporal data are most often described according to multiple and greatly diverse perceptions or viewpoints, using different terms and with heterogeneous levels of detail. Reconciling this heterogeneity to build a fully integrated database is known to be a complex and currently unresolved problem, and few formal approaches exist for the integration of spatio-temporal databases. The paper discusses the interope…
XA2C Framework for XML Alteration/Adaptation
2010
XML has crossed the borders of software engineering and has spread to other areas such as e-commerce, identification, information storage, instant messaging and others. It is used to communicate crucial data over these domains. Thus, allowing non-expert programmers to manipulate and control their XML data is essential. In the literature, this issue has been dealt with from 3 perspectives: (i) XML alteration/adaptation techniques requiring a certain level of expertise to be implemented and are not unified yet, (ii) mashups, which are not formally defined yet and are not specific to XML data, and (iii) XML-oriented visual languages based on structural transformations and data extraction mainl…
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…

Modernités dans les Amériques : des avant-gardes à aujourd’hui
2018
Reposer aujourd’hui la question de la modernité – littéraire, artistique, sociale ou politique – revient à employer le mot au pluriel. Ce choix implique que l’on ne se réduise pas au terme plurivoque, et souvent ambigu, de modernisme. Ce dernier, souvent convoqué pour désigner l’imaginaire culturel de la modernité, peine à rendre compte des écarts qui se manifestent dans la manière de penser le rapport au temps, à l’histoire et à la culture. « La modernité n’est pas un mouvement, comme dada o...
Analyse du partage d'informations contextuelles dans deux formes d'interaction sportives : coopérative et concurrentielle
2009
RESUME Plusieurs etudes ont souligne l’importance du partage d’informations contextuelles lors de tâches cooperatives. S’inspirant de la notion de contexte partage, notre etude visait a preciser le partage d’informations contextuelles dans deux formes d’interaction en tennis de table : une cooperative et une concurrentielle. Afin de reconstruire le partage d’informations contextuelles du point de vue des acteurs, cette etude a ete menee en reference au cadre theorique et methodologique du cours d’action (Theureau, 1992). Elle a permis : a) d’identifier trois formes typiques de partage des informations contextuelles ; et b) de preciser les processus regulant le partage de ces informations et…
