The important flow of these traces calls for a system to support their interpretation and understanding. We present our design and development of such a system in the digital music production context, within the Gamelan research project. This trace-based system is structured in three main layers: track production process, interpret collected traces according to a dedicated domain ontology, help querying and visualizing to foster production understanding. We conclude by discussing some hypotheses about trace-based knowledge engineering and digital music production understanding.

Though these singular systems take effect in the usual fields of expansion of music, they do not make any systematic reference to known musicological categories. On the contrary, they make possible experiments that open uses where listening, composition and musical transmission get merged in a gesture sometimes named as ?music-ripping?. We will show in which way the music-ripping practices provoke traditional musicology, whose canonical categories happen to be ineffectual to explain here. To achieve that purpose, we shall need: - to make explicit a minimal set of categories that is sufficient to underlie the usual models of computer assisted music;- to do the same for human-computer systems (anti-musicological?) that disturb us; - to examine the possibility conditions of reduction of the second set to the first;...

By browsing some eclectic experiences like dancing, serving $VWXULDQ FLGHU WU\LQJ WR HVFDSH 'DQWH¶V +HOO RU manufacturing a tyre, important questions are raised, and some answers are sketched about some possible ways of designing our future environments: but gestures have then to be considered as cultural objects too, being not reducible to their physical traces. 1.

Une tendance innovante se fait jour depuis peu, caracterisee par la mobilisation de l’informatique « a objets » pour ranger nos collections, considerees comme des amas d’objets en attente de rangement dans des classes ad hoc, qu’il s’agirait cette fois de construire dans le meme mouvement. En effet, faire collection est une activite plus originaire que classer, dans la mesure ou elle autorise l’experimentation concurrentielle des concepts 1° en extension (dans le cadre d’une disposition spatiotemporelle, meme provisoire et ephemere) et 2° en intension (dans la perspective d’un ordre abstrait de similarites, meme metastable). Reste que l’on fait toujours collection de quelque chose, ce qui interdit un typage de l’activite independant de ses objets et trouble ainsi les habitudes du modelisateur.

Among these systems those enculturated driven by cultural knowledge embed culture in their design. To deal with the specifics of cultural groups, the development of machine-readable cultural knowledge representations can provide a substantial help. In this research we present a process to build time-affordable, emic, conceptuallysound and machine-readable cultural representations. These representations originate from Cognitive Anthropology. They follow a three steps methodology: ethnographic sampling, individuals' personal knowledge elicitation and cultural consensus analysis. We use lexico-semantic relation extraction as a mean to automatically elicit knowledge structures. Their formalisation is achieved through Ontology Engineering. We conducted experiments to build three cultural ontologies in order to assess the whole process. It came out that with the lexico-semantic relation extraction technique, the best representations we can obtain are consensually-limited, incomplete and contain some errors. However, many clues indicate that these problems should be solved by using higher quality elicitation techniques.

They differ from traditional ones not only because they are virtual, but mainly because they offer to composers and listeners new perspectives of combinations and interactions between music, text and visual aspects.

Notre perspective est la conception d'environnements informatiques pour la création artistique scénique et sa réception, destinés à trois communautés d'utilisateurs : les créateurs d'oeuvres, les performeurs 1 sur scène, et le public au sens large. ABSTRACT. Noting that representations belonging to the « graphic sphere » undergo a severe crisis whereas multimedia representations have become more and more powerful and widespread, noticing that realtime computing is emerging in the field of scenic arts, we have carried out our research for several years on the topic of the mediation of information and communication technologies for the design of live shows (theatre and opera, mainly), and their recreation by spectators. Our perspective is the design of computerized environments for artistic creation on stage and its reception, intended for three communities of users: work creators, performers on stage and the audience in a broad meaning. MOTS-CLÉS. Médiations technologiques sur scène, interactions, environnements virtuels informés, collections figurales. KEYWORDS. Technological mediations on stage, interactions, virtual informed environments, figural collections. 1 Le performeur désigne tout artiste en situation de jeu scénique. Le terme, issu du performer anglais, incarne la dimension « performative » fondatrice du travail artistique engagé, dépassant l'interprétation de textes, et pouvant aller jusqu'à des formes d'improvisation. Par cohérence, nous conservons le terme anglais performance qui désigne ce travail scénique.

With a recent case-study – an immersive virtual reality art project dealing with some ancient abbey reconstruction and managed by a French engineering school – we analyse the successive attempts to satisfy the system users by extending Foucault's heterotopology, which appears to be useful and creative for the Virtual Reality research communities.

In this paper, we explore an other idea: we structure our material relationships by collecting objects within collections, which are never as static as classes. At the beginning of La Symphonie Pastorale by André Gide, the good pastor, having taken in Gertrude, tried

On the first part of the experiment, a 12-node graph is connected as a Rhythm Network and visualized with a Circular Layout, commonly known as Pitch constellation. This particular graph topology focuses on node structure and gives strength to weak edges. At this occasion, we unveil the Singularity Threshold, giving an opportunity to isolate structure from singular parts of melodies. Where usual Pitch constellations focus on chords, we focus on successive pitch intervals. On the second part, we propose a rhythm representation using a Force-Directed layout. In addition to structural information, our second technique shows proximal and peripheral elements. This experiment features 6 melodies that we propose to visualize using Gephi.

The important flow of these traces calls for a system to support their interpretation. We have studied and developed such a system in the digital music production context -- within the Gamelan research project -- towards musical object and process reconstitution. We present the results we obtained from combining trace engineering, knowledge modeling and knowledge engineering, based on the differential elaboration of a strongly-committed ontology, standard formats and common knowledge management tools. We conclude by discussing some hypotheses about trace-based knowledge management, digital music preservation and reconstitution, opening on to some considerations about artistic style and digital humanities aspects.

Then, through the case study of the scenic performance La Traversée de la nuit, we analyse some perspectives for designing an Informed Virtual Environment dedicated to live show artistic domain.

The current systems possess an artificial awareness of cultures by mediating them through representations. Coming from an etic approach, these universal representations facilitate the mediation of different cultures but limit their understanding and thus, prevent the development of an higher degree of awareness. In this research, we propose a methodology to construct artificial cultural awareness from emic-based representations. We tested the latter through an experiment on the domain of 'abortion' with the Pro-Choice and Pro-Life communities.

A better understanding of what is a crisis and a model of knowledge gathering appeared within the system development. We will explain this particular business process management through the successful example of the CHEOPS Project. pAper TexT When a company wants to offer a new tender for its clients in the geopolitical crisis management domain, it has to solve a dilemma. Firstly it has to build rapidly, a functional product in order to take a place on this well discussed market but on the long term this strategy isn’t sufficient. An incremental design process is required in order to organize an architecture, to bring out functional and ergonomic specifications, and to structure an ontological application such as a multi-agent cooperation model.Furthermore a reflection on what a crisis is, on the value...

Inspired by interactive data mining, that suggests different approaches, we give an overview of computer science and theater researches using computers as partners of the actor to escape the a priori specification of roles.

The manner in which both digital documents and the interactive tools allowing access to their content were assumed was to be seen in a different way, hence opening up to new innovative applications. However, analysing the systems aimed to help in document interpretation over the last fifteen years and based on Newell’s hypothesis, has lead to something quite unexpected: to conceive most of these systems, engineers have in fact been trying to deconstruct the hypothesis. Typically, the notion of collections has been preferred to that of knowledge. Yet perhaps the notion of collection could only appear once that of knowledge had been taken into account, distorted and finally subverted.

It uses a dramatic ontology and instantiation variations. Drawing our inspiration from the opposite approach through interactive data mining, we hereby account for theater research using computers as partners to actors to escape a priori specification of characters. Different approaches for staging a play With a new play to put on stage, every producer wishes to propose his own interpretation. Even if a lot of indications from the author are present in the preface or in the stage directions, interpretation is not inherently part of the text. A text cannot exist on stage without the interpretation of a producer. Dramatic ontologies and instantiation’s variations Actually this interpretation is an effort to create ‘patterns’. The producer begins his work by establishing a short ontology of the dramaturgy. He describes the characters using archetypes (some comedy uses t...

Opera can then be accessed at home and no longer in theatres. It is both an artistic project (as an opera creation) and a scientific one (in the ficld of human-machine interaction). We have first been modelling the interaction situation in traditional opera using an interagent collaboration formalism called MADEINCOOP. We then applied this model to the interactive opera performance, where a user faces a computer. For the interaction model, we have choscn to usc an analogy of a systcm of physical forces (e.g. electrical or gravitation forces). Forces and fields rule the evolution of the positions of the characters on the screen, whereas the uscrilistener triggers perturbations by bisiher actions. We are currently implementing the Virrrnulis project, using ...
