General purpose knowledge bases such as DBpedia and Wikidata are valuable resources for various AI tasks. They describe real-world facts as entities and relations between them and they are typically incomplete. Knowledge base completion refers to the task of adding new missing links between entities to build new triples. In this work, we propose an...

In this work we are interested in the problem of knowledge graph (KG) incompleteness, which we propose to solve by discovering implicit triples using observed ones in the incomplete graph leveraging analogy structures deducted from a KG embedding model. We use a language modelling approach that we adapt to entities and relations. The first results...

One of the major gaps in the current HTML5 web platform is the lack of an interoperable means for a multimodal application to discover services and applications available in a given space and network, for example, in a smart house with a network of connected objects. To address this gap, the Multimodal Interaction Working Group has produced a draft...

This paper proposes an approach for segmenting a Web page into its semantic parts. Such analysis may be useful for adapting blog or other pages on small devices. In this approach, we take advantage of both dynamic layout after rendering and textual information. Our method segments the page into blocks and then classifies the blocks. A classificatio...

In this paper, after presenting the context, which indicates a considerable increase in the need for the adaptation of multimedia documents, we show that these results can be obtained by the composition of basic services. Nevertheless, this requires the availability of semantic descriptions of services, for which a shared vocabulary and good practi...

A good way to deliver video and multimedia services to mobile terminals is to broadcast them. But, methods to broadcast interactive applications are very crude. In current broadcasting systems, the available bandwidth for interactive applications is and will remain heavily constrained by the associated video and audio streams. To overcome these con...

Most 2D graphic languages deployed on the Internet today lack the ability to represent the topology of contiguous regions efficiently. This is becoming problematic with the growing number of map-based applications. In this paper, we introduce a new graphical primitive, called Super Path, to extend existing languages for 2D vector graphics, such as...

Ces nœuds peuvent aussi bien être des utilisateurs que des pre...

In this paper, we focus on the problems of multimedia content personalization. We propose a new method/tool for authoring personalizable multimedia content. In other terms, our approach aims at helping the author (or the service provider) to generate a personalization process for an multimedia content which will be executed during the delivery of t...

Much research is currently being conducted towards Universal Multimedia Access, aiming at removing barriers that arise when multimedia content is to be consumed with more and more heterogeneous devices and over diverse networks. We argue that users should be put at the center of the research work to enable user-centric multimedia access. In this p...

The mobile industry, and in particular the 3rd Generation Partnership Project (3GPP) Consortium, has selected the "Tiny" profile of the scalable vector graphics (SVG) specification as a basis for the rich media format for mobile applications, leading the way to consumer electronics. Among the foreseen applications for SVG on constrained consumer el...

The use of proxies is commonplace in today’s MANETs, where they are used for a huge variety of network services. However the main problem of using proxies is that the end-to-end nature of the communication is broken. This leads to some severe security problems. One of the main questions that arise is how content caching by intermediaries can be don...

Our work focuses on the encoding of two-dimensional (2-D) graphics animated cartoons with MPEG-4. This stems from a need to stop encoding cartoons as videos and to start using methods more adapted to animated 2-D vector graphics sequences. We expected this could be an efficient coding with good versatility for various types of terminals. First, we...

"La communication écrite est encore jeune" écrivait R.Escarpit1 en 1973 ajoutant que celle-ci vieillissait moins vite que d'autres moyens de communication. Nous ne pouvons aujourd'hui que constater la pertinence de cette réflexion . En effet les formes de communication médiatisée par les technologies du numérique et des réseaux proposent une palett...
