....Multivariate Data 1. INTRODUCTION Visualisation of agent systems can be broken down into two different aspects: visualisation of single agents and multi agent systems. Although related, both areas focus on different aspects. Single agent visualisation is used for interface agents (see e.g. [1, 18, 8, 11, 16, 21]) The motivation is the end user, who has to interact with the agent system as effectively as possible. In contrast, multiagent visualisation is mainly motivated by the great complexity of multi agent systems and the need of developers and administrators to understand the internal workings of the ....

....course, in itself consistent and intuitive. Section 3 describes Ultima Ratio s visual language for agent internal argumentation and discusses its intuitiveness. The next step is to consider multiple agents. There has been some work developing extrinsic approaches for believable interface agents [2,24,13,15,19] and another intrinsic approach [26] We will go beyond these by combining intrinsic and extrinsic approaches in a visualization of avatars, representing the agents, engaged in a conversation with their spatial distance reflecting their relation. The paper is organized as follows: First, we ....

....seventies to visualize multi variate data, are an early approach into this direction. Although they are not accurate in capturing exact values of variables, they are useful to capture a limited number of qualitative values. Using facial expression is also studied extensively for believable agents [2,24,13]. Other agent properties, such as the number of messages exchanged or its credulousness can be reflected in the size and color of the agent. In our current implementation, which is part of ACA, the arguing and cooperating agents framework [20] the user selects an avatar to represent the agent ....

....for the presentation. This kind of agent can easily be used to create a virtual theatre [18] The second possibility is that the agent represents someone existing, a real human person. In the case of presentation, it can often be the author, with maybe some of his her assistants or friends [6]. In this case the agent has much more responsibilities, as any mistake or misconduct it may do can be ascribed to the represented human being. Features like emotion, personality or even behaviour can then take more importance than when the agents were only virtual. MPML will then make it ....

....to the characteristics which these agent interfaces appear to the user. These agents can take on many roles, adopting a range of human social conventions for the tasks they perform and the way they relate to the user. These roles can be summarised as follows (See also Mase, 1997; Wilson, 1997; Bickmore et al. 1998): Gurus The agent performs some reasoning (possibly prompted by the user) and supplies the results. Colleagues The user and the agent negotiate about the issue under consideration in a way similar to consulting a colleague (co worker) for an opinion. Assistants Secretary Agents or Guides; ....

....with documents seen by the user. Furthermore, we argue that an animated agent is a more flexible way of presenting such information than annotating links [4] or synthesizing web pages that summarize this information [5] We are influenced in our work by Bickmore, Cook, Churchill Sullivan [1] who have advocated animated autonomous personal representatives, i.e. scripted synthetic characters. Document Avatars that interact with readers of a document are one such application of such a representative. However, in our work, we desire for the agent to learn about its user and to learn ....

....reasons is proposed as a possible recommendation. The agent selects one of these by stochastically choosing a single recommendation with probability proportional to the overall strength of the recommendation. When making a recommendation, the agent can be viewed as a personal representative (cf. [1,6]) of the web site author. The agent infers from the user s actions whether the user followed the recommendation and increases or decreases the probability that future recommendations are made for that same reason for that user [3] This allows the system to learn whether a particular user prefers ....
