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…
ArchaeoKM: Managing Archaeological data through Archaeological Knowledge
2010
International audience; Nowadays, the use of ontologies in the field of the archaeology is a new direction of research that is not fully tested. Some results are very encouraging and challenge the vision of archaeological sites which cannot be modeled semantically. Most of the re-searches based on ontology technologies in the arc-haeology domain are based on the research of finding on a common ground for the interoperability and the integration of data. Papers like (LANG 2009), (KOLLIAS 2008) cover these research. The project ArchaeoKM is a shift from such researches. It focus-es on using the knowledge possessed by the archaeo-logists to model the data of an archaeological project, and to d…
A Federated Approach for Interoperating AEC/FM Ontologies
2016
International audience; Over the last few years, the benefits of applying ontologies (semantic graph modelling) for Architecture, Engineering, Construction and Facility Management (AEC/FM) industry have been recognized by several researchers and industry stakeholders. One of the main motivations is because it eases AEC data manipulation and representation. However, a research question that still remains open is how to take advantage of semantic web technologies to interoperate the AEC/FM and other ontologies in a flexible and dynamical way in order to solve data structure heterogeneity problem. Because of this, we propose in this paper to apply a rule-based federated architecture to answer …
THE IMAGE PROTECTOR A Flexible Security Rule Specification Toolkit
2011
International audience; The tremendous sharing of multimedia objects on the web shed the light on several privacy concerns related in essence to the safe publishing of end users' personal data. Providing techniques to protect multimedia objects faces several difficulties due to multimedia objects' heterogeneous and complex structure on one hand, and on the other hand, the wide range of information that could be used to describe their content. In this paper, we present a flexible security rule specification toolkit for multimedia objects. Our toolkit is based on a security model and a core ontology in which we populate the model's related information and multimedia objects data. To specify s…
Adding Knowledge Extracted by Association Rules into Similarity Queries
2010
International audience; In this paper, we propose new techniques to improve the quality of similarity queries over image databases performing association rule mining over textual descriptions and automatically extracted features of the image content. Based on the knowledge mined, each query posed is rewritten in order to better meet the user expectations. We propose an extension of SQL aimed at exploring mining processes over complex data, generating association rules that extract semantic information from the textual description superimposed to the extracted features, thereafter using them to rewrite the queries. As a result, the system obtains results closer to the user expectation than i…
Spatial Rules through Spatial Rule built-ins in SWRL
2010
International audience; The paper presents a method to include spatial rule within rule languages like SWRL to infer spatial rules within semantic web framework. The concept presented here could benefit both geospatial community as they benefit using the adjusted knowledge base to infer spatial rule and semantic web community as the inclusion of spatial data in its framework
Experimental and theoretical study of line mixing in methane spectra. III. The Q branch of the Raman nu(1) band
2000
International audience; The shape of the nu(1) Raman Q branch of CH4 perturbed by Ar and He at room temperature has been studied. Stimulated Raman spectroscopy (SRS) experiments have been made in the 2915-2918 cm(-1) spectral region for total pressures from 0.4 to 70 atm and mixtures of approximate to 5% CH4 with He and Ar. Analysis of the spectra demonstrates that the shape of the Q branch is significantly influenced by line mixing and much narrower than what is predicted by the addition of individual line profiles. For the first time, a model is proposed for the calculation and analysis of the effects of collisions on the considered spectra. In this approach, the rotational part of the re…
Intervento
2020
The article intends to give an account of the terms of the debate regarding the relationship between the CAP and competition, highlighting the tensions between the Commission and Parliament and the repercussions in legislative choices in a dimension that still seems unresolved today. The oscillations of the pendulum between PAC and Antitrust in the context of the regulation of the agri-food system seem to reappear also in the regulation of unfair commercial practices. It does not seem easy to propose a reading that is not necessarily dichotomous, which would like to make a dimension of commonality between the discipline of competition and the CAP prevail, although an awareness, even among j…
Introduction to the special issue: Beyond self-fashioning and freedom—bending, breaking, and adhering to rules in religious contexts
2023
Rules are a crucial part of much religious thought and practice. Their importance or insignificance, their strictness or laxness, and their rigidity or flexibility in the face of change are constant themes of debate, both within and outside religious communities. Yet they have arguably not been given the attention they deserve within recent anthropology. Since the rise of practice theory, rules have more often been considered something to look past in the search for agency. Where the new anthropology of ethics has addressed religious orthopraxy, it has largely been through the lens of the cultivation of virtuous self, or the ways in which moral rules may become especially salient in extrao…
