Hypervideo offers enhanced video-centric experiences. Usually defined from a hypermedia perspective, the lack of dedicated specification hampers hypervideo domain and concepts being broadly investigated. This article proposes specialized model that addresses specificities.

Effective video-based Web information system deployment is still challenging, while the recent widespread of multimedia further raises demand for new online audiovisual document edition and presentation alternatives. Hyper video, a specialization hypermedia focusing on can be used to provide basis video-centric documents allow more elaborated practices video. In this paper, we propose an annotation-driven model conceptualize hyper videos, promoting clear separation between video...

Learning Analytics Dashboards (LADs) deliver rich and actionable representations of learning data to support meaningful insightful decisions that ultimately leverage the process.Yet, because their limited adoption complex nature data, design is still a major area inquiry.In this paper, we propose expand LAD codesign approaches.We first investigate how user makes sense delivered by LADs sensemaking process at design.Second, generative tool, supporting decision making process, extends...

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 reading traces. We first describe conceptual framework with various levels of assistance for reengineering: indications on reading, problem detection, reconception suggestions automatic propositions, taking our example e-learning management. then present technical its associated models...

In the multimedia documents authoring systems management of spatial and temporal inter-objects relations is most delicate task. Spatial refers to appropriate means express between document objects guarantee their consistency. Usually it represented by model which performances depend on its expressivity degree, positioning precision ability a desired overlap. One important factor that affects distance associated relations. To enhance degrees allow specification overlap, we introduce, in this...

A challenge that course authors face when reviewing their contents is to detect how improve courses in order meet the expectations of learners. In this paper, we propose an analytical approach exploits learners' logs reading provide with insightful data about consumption courses. We first model activity using concept reading-session and a new efficient session identification. then elaborate list indicators computed sessions allow represent behaviour infer needs. evaluate our proposals...

Learning analytics dashboards (LAD) deserve increasing attention, yet their adoption remains limited. Designing effective LAD is a difficult process, and LADs often fail in turning insights into action. We argue that providing explicit decision-making features participatory design process may help to develop supporting first examine how the reflected on LADs. Second, we review literature identify major space dimensions include features. Third, propose DEFLAD framework synthesise this which...

Delivering high-quality content is crucial for effective reading comprehension and successful learning. Ensuring educational materials are interpreted as intended by their authors a persistent challenge, especially with the added complexity of multimedia interactivity in digital age. Authors must continuously revise to meet learners' evolving needs. Detecting barriers identifying actionable improvements within documents complex, particularly education where fundamental. This study presents...

In the rapidly evolving landscape of digital content, task summarizing multimedia documents, which encompass textual, visual, and auditory elements, presents intricate challenges. These challenges include extracting pertinent information from diverse formats, maintaining structural integrity semantic coherence original generating concise yet informative summaries. This paper introduces a novel framework for document summarization that capitalizes on inherent structure to craft coherent...
