(2012) Advene as a Tailorable Hypervideo Authoring Tool: a Case Study in ACM Symposium on Document Engineering, Paris, sept 2012, pp. 79-82 . doi Show abstract Audiovisual documents provide a great primary material for analysis in multiple domains, such as sociology or interaction studies. Video annotation tools offer new ways of analysing these documents, beyond the conventional transcription. However, these tools are often dedicated to specific domains, putting constraints on the data model or interfaces that may not be convenient for alternative uses. Moreover, most tools serve as exploratory and analysis instruments only, not proposing export formats suitable for publication. We describe in this paper a usage of the Advene software, a versatile video annotation tool that can be tailored for various kinds of analyses: users can define their own analysis structure and visualizations, and share their analyses either as structured annotations with visualization templates, or published on the Web as hypervideo documents. We explain how users can customize the software through the definition of their own data structures and visualizations. We illustrate this adaptability through an actual usage for interview analysis.

This creative process consists in describing, criticizing and building an analysis during the reading of a document. More and more tools aim at providing ways to perform part of this activity, built on diferent description models. However, the whole activity is lacking a full support. In this paper, we present our work on a unified model for active reading of audiovisual documents, taking into account each part of this activity. Our approach is based on active reading data and activity modeling so as to propose a pertinent, generic and adaptive model.

Pour ce faire, nous nous proposons d’analyser le film de Lars Von Trier et Niels Vørsel Epidemic (1988 ; tourné en noir et blanc). Partant d’une étude détaillée du fonctionnement sémio-stylistique de ce film, nous entendons montrer : (1) Qu’il se présente comme un « système textuel » (cf. Metz 1971 : 107-108 et passim) découlant d’une série d’interactions extrêmement complexes entre différents codes sémiotiques (discursifs, picturaux, narratifs, génériques …) ; (2) Que sa dimension « pluri-codique » (Metz 1971 : 90) doit être décrite dans le cadre d’une approche résolument interdisciplinaire, permettant de conjoindre aux acquis de la sémiotique filmique une série de concepts empruntés à la stylistique textuelle (le concept riffaterrien de « convergence »), à la narratologie (le concept genettien de « métalepse narrative »), à la philosophie du langage (le concept goodmanien d’« exemplification », le concept derridien d’« indécidabilité ») etc. ; (3) Que l’efficacité d’une telle démarche d’analyse est démultipliée par l’utilisation d’outils informatiques adéquats, qui peuvent être développés ad hoc.

It is based on the Advene project, providing a model and a prototype for creating, rendering and sharing annotations of audiovisual documents. After a presentation of the notion of multi-structurality in documents and a definition of hypervideos, we present the original Advene model. We then discuss some limitations observed in our model, and introduce a new model for hypervideos. We finally discuss related work with respect to our model, and raise the problem of the emergence of semantics in videos and hypervideos.

It allows users to define by themselves, according to their specific tasks, the structure of the metadata as well as the different ways in which it should be visualised. By storing metadata and visualisation specifications independently from the audiovisual document, it allows to share analyses and comments on any audiovisual document. Its open nature and simple principles make it an ideal testbed for experimentation with new audiovisual metadata interaction modalities.

In the search for new methods and tools, we focus in this article on the use of audiovisual material in a scholar context. One of the results of active reading applied to audiovisual material can be hypervideos, that we define as views on audiovisual documents associated with an annotation structure. The notion of hypervideo is useful to analyse existing video-based hypermedia systems as well as building new systems. The Advene project proposes an implementation of hypervideos through a framework that allows experimentations of new visualisation and interaction modalities for enriched videos.

If we are to undergo such a revolution in the audiovisual domain, a number of issues mainly related to the temporal nature of audiovisual documents have to be resolved. In this article, we expose our view of the current state of Audiovisual Information Systems, and suggest that they should be considered as video information management systems rather than video retrieval systems, in order to foster new uses of video information. We define the notion of hypervideo that can be used as an analysis framework for this issue. We then describe our implementation of hypervideos in the Advene framework, which is aimed at DVD material annotation and analysis. We eventually discuss how the notion of hypervideo puts video information retrieval in a somewhat different light.

  Additional comments

  The aim of this transdisciplinary program EPISTEME is first to identify the most characteristic aspects of the transformation of two chosen disciplines (astrophysics, history) in their relations to their objects under the effect of digital formalization. The other goal is to design instruments for the scientific communities of peers that allow contributive categorization, to support debates and controversies, based on the concept of transindividuation, and to articulate bottom-up -stemming from individual research activities- and top down processes -more or less local, laboratory-, school- or discipline-wide certification processes from peer community debates.

  We developed the Herschel Mission Explorer. We are currently working on a second version that will feature a general design overhaul.

During two sessions, pairs of students used the Visu videoconferencing tool for synchronous interaction and marker setting (positive, negative or free) and then individual report building on the interaction (using markers or not). A quantitative descriptive analysis was conducted on the markers put in action, on their use to reflect on action and on the reflection categories of the sentences in these reports. Results show that the students (1) used the markers equally as a note-taking and reflection means during the interaction, (2) used mainly positive markers both to reflect in and on action; (3) paid more attention in identifying what worked in their interaction (conservative direction) rather than in planning on how to improve their group work (progressive direction); (4) used mainly their own markers to reflect on action, with an increase in the use of their partners' markers in the second reflection reports; (5) reflected mainly on their partner in the first reflection reports and more on themselves in the second reports to justify themselves and to express their satisfaction.

Show abstract An exploratory study has been conducted in which 12 students in Bachelor of Science in Psychology were asked to use the Visu reflection tool during Computer-Supported Collaborative Learning (CSCL) situations. Visu is a web videoconferencing platform that allows participants to put reflective markers during their collaborative learning activity, and to review the traces of their synchronous collaboration later. In this study, co-learners used two types of markers: (1) free markers and (2) socio-emotional markers to express either negative or positive feelings about the way they collaborate together. Our contribution is related to the first focus of the workshop: emotion awareness in CSCL. In line with this focus, our main questions are as follows: (1) How can the Visu tool help learners express and share their feelings about collaboration? How does this affect the way they interact and learn together? (2) How do they use the Visu markers after the collaboration to self-reflect on their group processes? In this paper, we first describe the Visu platform. We then present a study we have carried out to answer the questions presented above. We finally conclude with the contributions of our research to the workshop topic.

(2012) Managing written and oral negative feedback in a synchronous online teaching situation in Computer-Assisted Language Learning, 25(2):181-197, 2012. doi Show abstract This case study focuses on the feedback that is provided by tutors to learners in the course of synchronous online teaching. More specifically, we study how trainee tutors used the affordances of Visu, an experimental web videoconferencing system, to provide negative feedback. Visu features classical functionalities such as video and chat, and it also offers a unique marking tool that allows tutors to take time-coded notes during the online interactions for later pedagogical remediation. Our study shows that tutors mainly use verbal and chat feedback, with significant inter-individual variability, and that tutors who provide verbal feedback are more likely to use markers. Marking takes time because of the dual task that it entails for the tutor. Idiosyncratic strategies in the use of markers are evidenced. These results clearly show the value of markers for negative feedback, signal the need for their explicitness, and also call for an evolution of the Visu interface so that tutors can better negotiate the task of online tutoring and the pedagogical stance they have to take on in their interactions with the learners.

[AR:36%] Show abstract This article presents a pilot study carried out to investigate the potential of a functionality marker setting, included in a synchronous collaborative videoconferencing platform (VISU). Markers, supported by a trace-based system, are designed to facilitate tutors' activity. They provide tutors with (1) the possibility of annotating their distant learners' learning activity, and (2) information pertaining to their own behavior during pedagogical interaction, which can potentially enhance their professional performance as online language tutors. This study concentrates on the marker-based traces of eight language tutors collected in the course of pedagogical interactions with their distant learners during a seven-week transnational collaborative project. It presents both quantitative and qualitative analyses of the use of markers during synchronous language teaching sessions and assesses the utility and usability of such a functionality for language tutoring in order to inform future design and training.

In this paper we introduce the redocumentation process of computer-mediated activity as a narrative construction that ties together the content of activity traces and the users’ knowledge in describing their activities in new easily exchangeable documents. We present a generic semi-automatic approach for this process, which is based on rhetorical structure theory. This approach uses formal models for process input and output, and handles the process through two main phases: an automatic phase to generate a fragmented document from traces as a first description of the activity and an interactive phase to allow the user to tailor this first description according to his particular needs and choices. We also present ActRedoc, a tool developed for text-based redocumentation, for which a first evaluation was conducted.

In this paper we are interested in describing a computer mediated activity by a person throughout a semi-automatic redocumentation process. This process uses traces generated automatically, during a user-system interaction, to assist a person in producing a personalized document describing the traced activity. To support that, a general framework for an authoring tool is proposed through two main phases. During the first phase, an automatic and parameterized transformation is applied on the input activity trace to generate a fragmented document. Each fragment describes one or many observed elements of the modeled trace and relations between fragments are deduced from relations between these elements. The second phase consists in interactive transformations on the intermediate produced document until getting the final hypermedia document. Our authoring tool uses composition of personalized document issues and RST principals to interpret user's choices and to maintain the coherence of the produced document.
