    In : The third international conference on iInformation and Communication Technologies: From Theory to Applications (ICTTA 2008), (Institute of Electrical and Electronics Engineers ( IEEE ), Damas - Syrie, 2008-04-07)
    In the multimedia documents authoring systems the management of spatial and temporal inter-objects relations is the most delicate task. Spatial relations management refers to the appropriate means to express relations between the document objects and guarantee their consistency. Usually it is represented by spatial ...

    Sadallah, Madjid; Encelle, Benoît; Maredj, Azze-Eddine; Prié, Yannick
    In : 13th ACM symposium on Document engineering DocEng 2013, (ACM New York, NY, USA, Florence, Italy, 2013-09)
    This ongoing work investigates usage-based document reengineering as a means to support authors in modifying their documents. Document usages (i.e. usage feedbacks) cover readers' explicit annotations and their reading traces. We first describe a conceptual framework with various levels of assistance for document ...

    In : Colloque Africain sur la recherche en informatique et mathématiques appliquées (CARI'10), (Yamoussoukro - Cote d’ivoire, 2010-10-18)
    Dans le domaine de l’édition et de documents multimédia, la gestion du placement spatial des objets constitue un des points le plus délicats dans la conception de documents. Il s'agit de pouvoir exprimer les relations spatiales entre les objets et de garantir leur cohérence. Cette gestion est représentée par un modèle ...
  • CHM: an annotation-and component-based hypervideo model for the Web 

    Sadallah, Madjid; Aubert, Olivier; Prié, Yannick
    In : Multimedia Tools and Applications;Special Issue: Multimedia on the Web, (Springer Verlag, 2012-07-21)
    Hypervideos are hypermedia documents that focus on video content. While they have long been deployed using specialized software or even hardware, the Web now offers a ground for them to fit into standardized languages and implementations. However, hypervideo design also currently uses very specific models limited to a ...
  • Component-based hypervideo model: high-level operational specification of hypervideos 

    Sadallah, Madjid; Aubert, Olivier; Prié, Yannick
    In : The 11th ACM symposium on Document engineering (DocEng 2011), (ACM New York, NY, USA, Mountain View, California. USA., 2011)
    Hypervideo offers enhanced video-centric experiences. Usually defined from a hypermedia perspective, the lack of a dedicated specification hampers hypervideo domain and concepts from being broadly investigated. This article proposes a specialized hypervideo model that addresses hypervideo specificities. Following the ...
  • Component-based Hypervideo Model: high-level operational specification of hypervideos 

    Sadallah, Madjid; Aubert, Olivier; Prié, Yannick
    In : Rapports de recherche internes, (CERIST, Alger, 2011-06)
    Hypervideo offers enhanced video-centric experiences with attractive and powerful features. Usually defined from a hypermedia perspective, the lack for a dedicated specification prevents hypervideo domain and concepts from being broadly investigated. This article proposes a formal hyper¬video model beyond conventional and ...
  • Extension of the Wahl-Rothermel temporal model for the multimedia documents 

    Maredj, Azze-Eddine; Alimazighi, Zaia; Sadallah, Madjid
    In : The first International Conference on information and communication Technology and accessibility (ICTA 2007), (Hammamet-Tunisia, 2007-04-12)
    Multimedia presentation defines composition of different media having inherent or assigned temporal behavior: text, images, animations, audio and video. Temporal composition is the most important feature of multimedia presentations because it defines the overall scheduling of temporal events. In this paper, our goal is ...
  • Hypervideo and Annotations on the Web 

    Sadallah, Madjid; Aubert, Olivier; Prié, Yannick
    In : The 2011 Workshop on Multimedia on the Web (MMWeb 2011), (IEEE Computer Society Washington, DC, USA, Gretz, Austria., 2011-09-08)
    Effective video-based Web information system deployment is still challenging, while the recent widespread of multimedia further raises the demand for new online audiovisual document edition and presentation alternatives. Hyper video, a specialization of hypermedia focusing on video, can be used on the Web to provide a ...
  • Leveraging Learners' Activity Logs for Course Reading Analytics Using Session-Based Indicators 

    Sadallah, Madjid; Encelle, Benoît; Maredj, Azze-Eddine; Prié, Yannick
    In : (Inderscience, 2018)
    A challenge that course authors face when reviewing their contents is to detect how to improve their courses in order to meet the expectations of their learners. In this paper, we propose an analytical approach that exploits learners' logs of reading to provide authors with insightful data about the consumption of their ...
  • MediaStudio : Un système d’édition et de présentation de documents multimédia interactifs 

    Maredj, Azze-Eddine; Sadallah, Madjid; Tonkin, Nourredine
    In : Revue de l'Information Scientifique et Technique (RIST), (CERIST, Ben Aknoun - Alger, 2010)
    In the actual standards and multimedia systems, the documents are often written in an event based approach which makes the programming techniques not adapted to the incremental edition process. The documents maintenance has become very hard and very expensive and the construction of such documents is not adapted to the ...
  • Un modèle logique de documents pour les interactions multimédia 

    Maredj, Azze-Eddine; Alimazighi, Zaia; Tonkin, Nourredine; Sadallah, Madjid
    In : Conférence internationale d’électronique et d’Automatique (JTEA' 08), (JTEA, Hammamet-Tunisie, 2008-05-02)
    La dimension temporelle d’un document multimédia interactif confère à ses objets des comportements différents de ceux d’un document classique. De nouveaux besoins de lecture doivent être considérés pour maîtriser sa complexité de perception. Les interactions utilisateur sont une solution à ces besoins. Toutefois, dans ...

  • Towards Reading Session-based indicators in Educational Reading 

    Sadallah, Madjid; Encelle, Benoît; Maredj, Azze-Eddine; Prié, Yannick
    In : Rapports de recherche internes, (CERIST, Alger, 2015-06)
    It is a challenging task to identify eLearning courses parts that have to be revised to best suit learners’ requirements. Reading being one of the most salient learning activities, one way of doing so is to study how learners consume courses. We intend to support course authors (e.g. teachers) during courses revision by ...
