Comment représenter des connaissances de manière formelle pour que des logiciels puissent les utiliser ? Plein de trucs ont été essayés et ce qui marche bien c'est la structure de graphe. Les noeuds sont des entités et les liens des relations entre elles. Bon, on a un peu trop simplifié. Fabien Gandon nous parle des graphes de connaissance, une...

Linked Multi-Agent Systems (MAS) is a vision where MAS are linked through their resources and representations, supporting knowledge augmentation for human and software agents on the Web and the linking and interoperability of different MAS. The goal of Linked MAS should not be to have one MAS platform or one MAS system on the Web but to allow...

This abstract paper (from Dagstuhl Perspectives Workshop 18262 - 10 Years of Web Science: Closing The Loop) summarizes some challenges and opportunities at the intersection of Web Science, Artificial Intelligence and Intelligence Augmentation.

XML technology and multi-agents systems are new approaches offering interesting assets for corporate memory management. Since ontologies appear as key assets in the new generation of information systems and also in the communication of multi-agents systems, it comes with no surprise that it stands out as a keystone of multi-agents information...

Quel pourrait être un point commun entre se renseigner à propos d'un concert, effectuer un virement depuis son compte bancaire, publier une base de données génomiques, échanger avec ses enfants à l'autre bout du monde et accéder aux données de sa voiture? Le fait de pouvoir le faire à travers leWeb. Il est en effet difficile de trouver une...

Que ce soit dans vos choix de séries TV à regarder, dans l'analyse de vos résultats médicaux, dans vos rencontres amoureuses, dans l'attribution de votre prêt ou dans les réglages de vos prises de photosles IA mettent leur grain de sel partout. Ce qui rend peut-être d'autant plus surprenante la réponse à cette question : non, aujourd'hui, les...

Pour comprendre la récursivité, il faut avant tout... comprendre la récursivité. »-Stephen Hawking Mes anciens collègues sont partis et je reste assis dans ce rocking chair qu'ils m'ont offert ; prostré entre photo d'adieu et cliché de retraite. Mais il était temps que l'on me retire la craie et l'éponge car je commençais à les confondre avec...

This position paper defends the idea that the development of the Web to its full potential requires addressing the challenge of massive multidisciplinarity. It was triggered by the topic of a joint panel at the conferences CLOSER and WEBIST 2014.The topic of the panel was: " social, political and economic implications of the cloud and the Web...

This paper is a survey of the research topics in the field of Semantic Web, Linked Data and Web of Data. This study looks at the contributions of this research community over its first twenty years of existence. Compiling several bibliographical sources and bibliometric indicators , we identify the main research trends and we reference some of...

In this keynote abstract I mention a number of works from the research team Wimmics (pronounced "we mix") that has been studying the challenges in bridging social semantics and formal semantics on the Web. These contributions address some of the challenges in connecting AIs to the Web.

This article describes a multi-agent software architecture to manage a corporate memory in the form of a corporate semantic Web. It summarizes the design rationale and the final architecture of the CoMMA system. It then presents and discusses an approach to manage distributed annotations, focusing on two problems: the allocation of newly posted...

This work concerns multi-agents systems for the management of a corporate semantic web based on an ontology. It was carried out in the context of the European project CoMMA focusing on two application scenarios: support technology monitoring activities and assist the integration of a new employee to the organisation. Three aspects were...

This paper presents an approach to design a multi-agent system managing a corporate memory in the form of a distributed semantic web and describes the resulting architecture.

The diversity of resources and information in real infospheres calls for artificial ecosystems with a diversity of interacting agents ranging from reactive to deliberative paradigms and maintaining the information ecology. After discussing the notion of infosphere and some interests of the XML family for such a world, this paper provides...

What could be a common point among getting information about a concert, transferring money from one's bank account, publishing a genomics database, communicating with one's children on the other side of the planet, and accessing information about one's car ? The fact that they can all be done through the Web. It is indeed difficult to think of...

L'évolution du Web documentaire vers le « Web des données » repose sur des principes et standards, permettant de tout identifier, de tout décrire sur la toile, et de tisser ainsi un graphe de données mondial. Le « Web sémantique », dans un second temps, permet la formalisation, la publication et le liage des vocabulaires utilisés dans ces...

XML and multi-agents technologies offer a number of assets for corporate memory management. Since ontologies appear as a key asset in the new generation of information systems and also in the communication layer of multi-agents systems, it comes with no surprise that it stands out as a keystone of multi-agents information systems. Here, we...

Although it was initially an "Information management proposal" the Web really is a successful « application integration platform ». More importantly, it is both. It is a self-documenting hypermedia system for application and information integration, and that makes the Web very special. Just like it is important to propose a Web of linked data...

The semantic Web is a vision of a Web augmented with formalized knowledge annotating it. Currently, there is a huge gap between the conceptual structures underlying the semantic Web and the final rendering of a user-interface enabling an end-user to peruse or act on part of it. We describe an approach we experimented to automate part of the...

Depuis son apparition au sein du W3C, la définition de la ressource Web n'a cessé d'évoluer au delà du simple document. Lieu, service, concept d'ontologie, représentation d'un objet réel ou non, la ressource web est complexe et il nous a semblé que les outils à disposition des internautes pour sa manipulation, comme les bookmarks par exemple,...

Two strong tendencies in social networks today are their growing multidimensionality and the key role of social objects around which they crystallize. We define OCSO as semantic web schema to describe finely these social objects and their afferent social activity. Then we defend the use of spreading activation algorithms to perform complex...

In this paper we address the problem of predicting SPARQL query performance. We use machine learning techniques to learn SPARQL query performance from previously executed queries. Traditional approaches for estimating SPARQL query cost are based on statistics about the underlying data. However, in many use-cases involving querying Linked Data,...

The absence of clarity concerning the licensing terms does not encourage the reuse of the data by the consumers, thus preventing further publication and consumption of datasets, at the expense of the growth of the Web of Data itself. In this paper, we propose a general framework to attach the licensing terms to the data queried on the Web of...

We address the problem of predicting SPARQL query performance. We use machine learning techniques to learn SPARQL query performance from previously executed queries. We show how to model SPARQL queries as feature vectors, and use k -nearest neighbors regression and Support Vector Machine with the nu-SVR kernel to accurately (R^2 value of...
