Trace-Based framework for experience management and engineering

The paper deals with experience management in computer-mediated environments. It particularly focuses on complex tasks whose support relies more on experience than on knowledge. The presented approach is based on the “use traces” concept to investigate the “activity reflexivity” as a first step in experience management, and experience sharing and reusing as possible applications. The paper also outlines the framework supporting Trace-Based Systems creation. Traces, trace models and trace life cycle are formally defined. The main parts of the framework architecture: collecting, transformation, visualization, and query systems are also detailed.

Hypervideo and Annotations on the Web

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.

Démonstration: advene, un outil pour la lecture active audiovisuelle

The Advene project aims at providing a framework to practice active reading on audiovisual documents, through the annotation of the document and the visualisation of the annotations along user-defined modalities. It involves conceptual, technical and ergonomical issues, especially due to the dynamic nature of the annotated documents.

Construction d'une base de connaissance pour l'évaluation de l'usage d'un environnement STIC

Our goal is to determine how people will adapt to a computerized environment while they are a priori not educated to their manipulation. We chose to couple two methods: regular observation using the traces of use generated by the interactions of the user with the system and more specific investigations. The combination of these two types of data in such context of study is original. In this paper we present the means used to collect, characterize and organize the observation data so that it is possible to exploit for various types of analysis.

Documents audiovisuels instrumentés : Temporalités et détemporalisations dans les hypervidéos

Nous nous interessons tout dabord dans cet article aux documents audiovisuels et aux diverses temporalites qui leur sont liees. Apres un etat des lieux des possibilites actuelles des systemes dinformation audiovisuelle, nous definissons plus precisement ce que sont les hypervideos, ou documents audiovisuels numeriques instrumentes. Nous decrivons et illustrons alors un certain nombre des caracteristiques des objets hypervideos en lien avec les temporalites definies, qui en font des objets complexes. Nous presentons alors un debut de cadre danalyse des synchronisations entre temporalites des hypervideos generees et vecues.

MAZETTE: Multi Agent MUSETTE for Sharing and Reusing Ontologies

During the realization of a document-mediated collective task the participants act and interact by creating documents and ontologies, by modifying them, annotating them and exchanging them. This article presents the general principles of a model based on a multi-agent architecture, aimed at facilitating the co-construction of common ontologies. The model is built on the MUSETTE (Modelling USEs and Tasks for Tracing Experience) approach, which was designed to provide users with assistance based on the recording and reusing of their system use traces. Our model, called MAZETTE (Multi-Agent MUSETTE), defines a framework for considering sharing and reusing of collective traces and experience, amongst which we focus on ontology co-construction and reuse.
