Terminology-based Text Embedding for Computing Document Similarities on Technical Content

We propose in this paper a new, hybrid document embedding approach in order to address the problem of document similarities with respect to the technical content. To do so, we employ a state-of-the-art graph techniques to first extract the keyphrases (composite keywords) of documents and, then, use them to score the sentences. Using the ranked sentences, we propose two approaches to embed documents and show their performances with respect to two baselines. With domain expert annotations, we illustrate that the proposed methods can find more relevant documents and outperform the baselines up to 27% in terms of NDCG

Multimedia Authoring for CoPs

9 pagesInternational audienceOne way of providing technological support for CoPs is to help participants to produce, structure and share information. As this information becomes more and more multimedia in nature, the challenge is to build multimedia authoring and publishing tools that meets CoPs requirements. In this paper we analyze these requirements and propose a multimedia authoring model and a generic platform on which specific CoPs-oriented authoring tools can be realized. The main idea is to provide template-based authoring tools while keeping rich composition capabilities and smooth adaptability. It is based on a component-oriented approach integrating homogeneously logical, time and spatial structures. Templates are defined as constraints on these structures

Indeterminate Adaptive Digital Audio for Games on Mobiles

A mobile game is a video game played on a mobile phone. The game market for mobiles is clearly regarded as a market with a future [11], as the multiple investments carried out by the large world editors on this segment testify. The mobiles are true platforms of large and general public games: mobile games can be downloaded via the mobile operator's radio network, WLAN, bluetooth or USB connection. Mobiles phones give game developers a unique set of tools and behaviours and with a little creativity, game developers can make some really great games for this platform. The challenges posed by portable devices are numerous, but the biggest complaint of many in the industry is the lack of standards. It is necessary to adapt each game to the various models of existing terminals, which do not offer the same features (memory, processing power, keys...). Consequently, the number of different versions of a game rises to several hundreds. As we will see, Java Micro Edition (J2ME) attempts with some success to solve these problems

Mobile Immersive Music

International audienceDue to obvious portability constraints, mobile technology excludes large electronic displays for visual immersion. On the contrary, sound heard over headphones is ideally suited for mobile applications. The use of stereo headphones or stereo speakers on mobile devices enables to take advantage of binaural technology which can provide an immersive sound experience for a variety of applications ranging from stereo widening of music (creating an out of the head listening experience) to full 3-D positional audio. Advances in audio are going to help bring in richer multimedia, increase quality of mobile music and help create more interactive and immersive audio applications. Interaction with sound in 3D audio space is no more limited to indoor environment [8]. In this paper, we report on an architecture for multimedia applications on mobile devices separating content creation (audio and graphics) from content manipulation. We have developed a markup format for interactive and spatialized audio on mobiles which can be used an interface between the sound designer and the application programmer. After presenting an overview of the key concepts in designing a format for interactive and spatialized audio and the methodology used to build the corresponding sound API , we describe its use in a mobile immersive music application for Copenhagen Channels where interactivity with the music is done through GPS waypoints

Terminology-based Text Embedding for Computing Document Similarities on Technical Content

International audienceNous proposons dans cet article une nouvelle approche hybride de calcul de représentation de documents dans le but de calculer des similarités entre documents techniques. Dans un premier temps, nous utilisons une méthode de l'état de l'art basée sur le graphe des mots pour extraire des phrases-clés, afin de calculer un score pour chacune des phrases du document. Nous proposons deux approches pour calculer la représentation d'un document en utilisant ce classement des phrases. En utilisant des annotations d'experts du domaine, nous montrons que les méthodes proposées obtiennent de meilleurs résultats en terme de NDCG pouvant aller jusqu'à 27% d'amélioration
