    Towards reading session-based indicators in educational reading analytics
    (Springer, 2015-09) Sadallah, Madjid; Encelle, Benoît; Maredj, Azze-Eddine; Prié, Yannick
    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 providing them with reading indicators. We use the concept of reading session to denote a learner's active reading period, and we provide several associated reading indicators. In our server-side approach, reading sessions and indicators are calculated using web server logs. We evaluate the relevance of our proposals using logs from a major French eLearning platform. Results are promising: calculated reading sessions are theoretically more precise than other best applicable approaches, and course authors consider suggested indicators to be appropriate to courses revision. Using reading sessions and associated indicators could facilitate authors' work of course reengineering.

    A Framework for Usage-based Document Reengineering
    (ACM New York, NY, USA, 2013-09) Sadallah, Madjid; Encelle, Benoît; Maredj, Azze-Eddine; Prié, Yannick
    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 reengineering: indications on reading, problem detection, reconception suggestions and automatic reconception propositions, taking our example in e-learning document management. We then present a technical framework for usage-based document reengineering and its associated models for documents, annotations and traces representation.

    Component-based hypervideo model: high-level operational specification of hypervideos
    (ACM New York, NY, USA, 2011) Sadallah, Madjid; Aubert, Olivier; Prié, Yannick
    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 principles of component-based modeling and annotation-driven content abstracting, the Component-based Hypervideo Model (CHM) that we propose is a high level representation of hypervideos that intends to provide a general and dedicated hypervideo data model. Considered as a video-centric interactive document, the CHM hypervideo presentation and interaction features are expressed through a high level operational specification. Our annotation-driven approach promotes a clear separation of data from video content and document visualizations. The model serves as a basis for a Web-oriented implementation that provides a declarative syntax and accompanying tools for hypervideo document design in a Web standards-compliant manner.

    Hypervideo and Annotations on the Web
    (IEEE Computer Society Washington, DC, USA, 2011-09-08) Sadallah, Madjid; Aubert, Olivier; Prié, Yannick
    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 basis for video-centric documents and to allow more elaborated practices of online video. In this paper, we propose an annotation-driven model to conceptualize hyper videos, promoting a clear separation between video content/metadata and their various potential presentations. Using the proposed model, features of hyper video are grafted to wider video-based Web documents in a Web standards-compliant manner. The annotation-driven hyper video model and its implementation offer a general framework to experiment with new interaction modalities for video-based knowledge communication on the Web.
