A Semantic Publish/Subscribe Approach for U-VR Systems Interoperation
2008
As ubiquitous virtual reality (U-VR) systems become more and more popular and several systems coexist all together, sharing events between them in order to improve the user experience and increase their scope and functionality will be mandatory. Since U-VR systems have a dynamic and decoupled nature, and they have their own event model, we propose in this paper a semantic publish/subscribe infrastructure that lies on a description logics reasoner and OWL ontologies for managing heterogeneous event models and performing the matching of events and subscriptions in such U-VR systems.
Towards A Twitter Observatory: A Multi-Paradigm Framework For Collecting, Storing And Analysing Tweets
2016
International audience; In this article we show how a multi-paradigm framework can fulfil the requirements of tweets analysis and reduce the waiting time for researchers that use computational resources and storage systems to support large-scale data analysis. The originality of our approach is to combine concerns about data harvesting, data storage, data analysis and data visualisation into a framework that supports inductive reasoning in multidisciplinary scientific research. Our main contribution is a polyglot storage system with a generic data model to support logical data independence and a set of tools that can provide a suitable solution for mixing different types of algorithms in or…
Semantic User Profiling for Digital Advertising
2015
International audience; With the emergence of real-time distribution of online advertising space (“real-time bidding”), user profiling from web navigation traces becomes crucial. Indeed, it allows online advertisers to target customers without interfering with their activities. Current techniques apply traditional methods as statistics and machine learning, but suffer from their limitations. As an answer, the proposed approach aims to develop and evaluate a semantic-based user profiling system for digital advertising.
FOWLA, A Federated Architecture for Ontologies.
2015
International audience; The progress of information and communication technologies has greatly increased the quantity of data to process. Thus, managing data heterogeneity is a problem nowadays. In the 1980s, the concept of a Federated Database Architecture (FDBA) was introduced as a collection of components to unite loosely coupled federation. Semantic web technologies mitigate the data heterogeneity problem, however due to the data structure heterogeneity the integration of several ontologies is still a complex task. For tackling this problem, we propose a loosely coupled federated ontology architecture (FOWLA). Our approach allows the coexistence of various ontologies sharing common data…
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…
Generalizing relations during analogical problem solving in preschool children : does blocked or interleaved training improve performance ?
2017
International audience; Analogical reasoning, the mapping of structured relations across conceptual domains, is commonly recognized as essential to human cognition, but young children often perform poorly in the classical A:B::C:? analogical reasoning task. Particularly, young children have trouble when the objects in the task are not strongly associated with each other, and/or when there are strong associative lures among the potential answers. Here, we examine whether successive trials that repeat the same relation needed to solve the analogy can help overcome some of the challenges with weakly associated items. In the first of two experiments, our results were mixed. In the second, we si…
A Study of Students' Reasoning About “There exists no ...”
2018
International audience; In this paper, we report findings from two studies of students' engagement in metatheoretical tasks drawn from a model of the reasoning requirements of a proof by contradiction. The studies explored students' engagement in and success with the tasks, as well as the similarities and differences in students' and mathematicians' approaches. Findings indicate students tended towards syntactic, logical theory approaches while mathematicians gravitate towards semantic, mathematical theory approaches. Drawing on interview data, it is shown that students may use symbols to avoid employing fragile content knowledge, yet encounter further difficulties by viewing quantifiers as…
Analogical reasoning and its development : role of executive functions and the goal of the task
2013
This manuscript develops an issue related to the involvement of goal management capabilities and executive functions in this type of reasoning and its development. The first three experiments examine this issue in two tasks of analogical reasoning, the scene analogy task and the A:B::C:? task, through the study of visual strategies used by adults, and children aged 6-to-7. The results show differences in visual patterns related to goals, and to the inhibition of irrelevant information for the solution of the problems, between the different tasks, and between children and adults. The following two experiments study the visual strategies, always in relation to executive functioning and goal m…
Empatía en la adolescencia. Relaciones con razonamiento moral prosocial, conducta prosocial y agresividad
2016
ResumenEste estudio persigue un doble objetivo: i) analizar las relaciones entre empatía, conducta prosocial y razonamiento moral prosocial y sus diferencias en función del sexo; ii) analizar el valor predictor de dichas variables en la empatía, como variable dependiente. La población evaluada está compuesta por 1557 adolescentes de 12 a 15 años (M = 13.13, DT = .86; 47.4 % chicas; 52.6 % chicos). Los análisis muestran diferencias significativas entre chicos y chicas. Las chicas obtienen mayores índices de empatía, conducta prosocial, razonamiento moral prosocial, en las dimensiones de interiorizado, orientado hacia la necesidad y estereotipado. Los chicos, por su parte, muestran mayores ín…
