There is a kind of misunderstanding between the common way of art presentation in galleries and museums and the very emerging artistic forms, directly on electronic media (e.g. net art or virtual sculpture). Though the galleries and museums are getting on-line these days, still they treat the artists and artworks in an old-fashioned way. Even the progressive net-galleries are founded just on a simple point & click navigation which is hostile to both artists and audience. eGaLab (electronic gallery and laboratory) for virtual art reflects today's status under which the artists create and present their artworks. It introduces an intuitive approach in the field of virtual environments and communities oriented to visual arts and artistic collaboration. eGaLab combines and transforms the advantages of collaborative virtual environments with the traditional aspects of artistic creation and presentation. In this paper we describe architecture of the eGaLab platform. We describe its networking part based on a concept of General Variables (GV) and discuss several implementation issues related to its specific character.

This paper presents a distributed virtual reality environment for children. This virtual environment supports cooperation among members of a dispersed team engaged in a concurrent context. The virtual environment maintains a shared information space described in a standard Virtual Reality Modeling Language (VRML) format. Users are allowed to interact and to give decisions using cooperative mechanisms. A user-friendly interface enables teachers to create their own stories that fit with children pedagogical requirements and generates new virtual environments according to teacher's specifications. The implementation is based on DeepMatrix as environment server, VRML and Java as languages and Cortona VRML plug-in from ParallelGraphics. It is actually running on the Internet: http://www.enib.fr/eve.

Businesses operate today in an increasingly dynamic environment through a worldwide network of information exchanges and business transactions. The Semantic Web - an extension of the current Web - which comprises ontologies and XML-related technologies, provides a shared and standardized vocabulary that can be communicated among automatic and human agents to share information and knowledge. Consider that an electronic business is a set of business processes governed by business rules that run over the Internet. These business rules play a significant role in determining the success or failure of a business as a whole. The goal of this paper is to introduce a framework that is designed to build business systems faster and which can more easily accommodate changes within a business. The advantages of this framework arise from its unity and simplicity, and especially its ability to effectively change, add, and/or delete business rules.

With the development of communication methods and devices, it became possible to perform actions more and more distant from the task spaces. These new tools raise today the question of Presence of distant spaces with a growing accuracy. In a first part, we show that the distance between the manipulation space and the task space, in a teleoperation activity, points to different meanings. However, the same need for a strong Presence of the task space raises, whatever the distance between these spaces is. We then discuss the notion of Presence as a cross-point between technological and scientific disciplines, and propose some general idea that may reinforce it. In a second part, we illustrate the previous ideas with the example of manipulation of nano-objects. We show how it is possible to enhance dramatically the feeling of Presence of the nano-objects to be perceived and manipulated, by adding haptic bi-directional transducers to the visual and acoustical sensors used today. By the end, we defend the idea that the feeling of Being there is deeply dependent on multisensoriality.

The study on recommender systems always blinds to the profitability difference among customers. In our research, we have extended our previous work of segmenting customers based on their contributions by proposing a hybrid recommendation system which uses multi-agent system, collaborative filtering together to serve the customers with high profitability, while using simplified top-N to generate high efficient recommendations for the lower profitability customers. Also, agent-based recommendation strategy selection architecture has been proposed and examined in the hybrid recommendation system.

The scientific results of global archaeological excavations often take the form of books and papers, and on occasion, web sites and digital media. However, a large amount of the raw recorded data remains inaccessible to wider audiences. This paper proposes the development of a universal archaeological system that unites archaeological recordings from diverse sites, making easier the process of dissemination to both the wider public and the analysis and comparison of this data by the scientific community, enabling a more informed interpretation of our past. This is accomplished through a 3D cyber-world constructed from a variable level of detailed recordings from archaeological sites.

Space is important for learning and socializing. Cyberworlds provide a new space for socialization and communication with a great degree of flexibility, allowing users to create and manipulate virtual land. This suggests considering virtual spaces as artifacts. In this paper we use different theoretical approaches on artifacts and experiences of usage of a virtual world we have created to revise the original design and to derive a new set of requirements for virtual places and spatial artifacts.

In this paper we propose a new metaphor of information retrieving, usable in heritage management and publishing. Based on the net, the user is able to participate in virtual guided tours, sessions of conferences-like. A human expert will be the guide for all the connected users. He will use different media (sound/video) to communicate; the members of the guided group will communicate through chat sessions. Each virtual tourist will be autonomous in its 3D world movements but he will receive audio/video information or other multimedia documents or 3D objects, eventually autonomous entities placed in its 3D virtual universe, from its guide. The guide is able to suggest to its group of tourists some interesting viewpoints during the tour. More, he is able to augment the database, particularly the associated behaviours to the entities. It is enough to analyse the entities in a scene and to attach them some new behaviours. For example, he can place in the environment some virtual guides, and the users will interact with them. These virtual guides recognise some keywords or intentions; i.e. if a tourist spends some time near a specific place, the virtual guide will initiate a dialog upon the place's history. The user is able to cancel the dialog with a virtual guide and return to its group. The application is based on the AReViJava (Atelier de Realite Virtuelle) platform, developed in our laboratory.
本文提出了一种新的信息检索隐喻，可用于遗产管理和出版。基于网络，用户可以参加虚拟导游、会议之类的会议。人类专家将成为所有连接用户的向导。他会使用不同的媒体(声音/视频)进行交流;导游小组的成员将通过聊天会话进行交流。每个虚拟游客在自己的3D世界运动中都是自主的，但他将从导游那里接收音频/视频信息或其他多媒体文件或3D对象，最终将这些自主实体放置在自己的3D虚拟世界中。导游能够在旅游过程中向旅行团推荐一些有趣的景点。此外，他还能够增强数据库，特别是与实体相关的行为。分析场景中的实体并附加一些新的行为就足够了。例如，他可以在环境中放置一些虚拟向导，用户将与它们进行交互。这些虚拟指南识别一些关键词或意图;例如，如果游客在一个特定的地方附近待了一段时间，虚拟导游就会启动一个关于这个地方历史的对话。用户可以取消与虚拟导游的对话并返回到其群组。该应用程序基于AReViJava (Atelier de Realite Virtuelle)平台，由我们的实验室开发。

In cyberworlds as well as in real world environments there is a need to enable cooperation and communication. While IT support has enabled us to overcome the barriers of time and place in communication over distance, there is still the problem of bridging the gap across different cultures. In this paper we will study the possibility of IT support for "sharing culture", i.e. for communication across different cultures. Our attempt to realize this goal is the creation of a learning, proactive agent that keeps track of the communication in virtual environments. We try to support the communication partners during their interactions by providing information based on the type and content of the communication. The information provided by the agent is based on cultural differences that could lead to potential misunderstandings within a communication scenario. The idea is to design a pluggable agent to support cross-cultural communication for virtual communities in distributed environments.
