We shall present them here in a lightweight version in which those features not essential to our investigation will be left out. For a complete description of einstitutions refer to [22, 18]. Our lightweight e institutions are de ned as sets of scenes related by transitions. We shall assume the existence of a communication language CL among the agents of an e institution.

This has been described and discussed in detail in [17], while a more general, but also more technical approach appears in [22] This set of scenes and the connections between them what roles agents may play in them, how many of each role, to which scenes they may move constitute the performative structure for the electronic institution (see ....

To achieve this, the coordination media are exploited as both the conceptual and physical repository of the organisational rules [8, 30, 29] A somewhat similar approach has driven the implementation of the Fishmarket system for agent mediated auctions [27]. In the Fishmarket, the need to force agents to act in accordance with the social conventions that rule the organisation of an auction is recognised. To enact social conventions, the system dynamically associates a controller agent with each agent in the auction. Controller agents act as a ....

Carrel follows the approach of other well known Agent Mediated Institutions such as Fishmarket [2] [6] and AuctionBot [16] 14] in order to assure a fair distribution of resources.

Complexity comes not only from the amount of information Hospital s agents have to access or need to take into account in the transaction, but also from the fact that the actual conditions of deliberation are constantly changing and are uncertain new pieces are arriving to the system, the ....

Therefore, a dialogical institution can be understood as a set of ....

....multi agent system usually relies on some form of global laws that the agents living in it have to obey when interacting with other agents. For example, the correct functioning of agent mediated auctions require participating agents to comply to the conventions that rule each specific auction type [26]. In this chapter, we propose the adoption of coordination models [15, 8] as the conceptual abstraction that can be exploited in the analysis and design of multi agent systems for the Internet. Furthermore, we sketch how a coordination model can be exploited to make a methodology, such as Gaia, ....

....of the infrastructure needed to make all interactions compliant with the expected behaviour of the coordination media. For instance, this can be done by associating (even dynamically) specific communication stubs to the agents in the system, as was done, for example, in the FishMarket project [26]. 6 Conclusions and Future Work This paper has analysed the main issues that arise in engineering multi agent systems for the Internet. Specifically it has shown how a coordination model can act as a powerful abstraction for both the analysis, design, and actual development of multi agent ....

....specific coordination media , whose internal behaviour can be programmed so as to implement specific policies for governing agent interactions. However, this work tends not to define any methodology for the analysis and design of those systems. The Fishmarket system for agent mediated auctions [16] also recognises the need to force agents to act in accordance with the social conventions that rule the organisation of an auction. To this end, the system dynamically associates to each agent in the auction a controller agent. This agent is in charge of mediating all the interactions and of ....

Finally, we end up with a discussion about related work and an outline of our future work. 2. A Test bed for Auction Tournaments Following [13], the fish market can be described as a place where several scenes run simultaneously, at different places, but with some causal continuity. The principal scene is the auction itself, in which buyers bid for boxes of fish that are presented by an auctioneer who calls prices in descending order ....

....buyers need to register for the market, at the buyers registration scene. Likewise, once a box of fish is sold, the buyer should take it away by passing through a buyers settlements scene, while sellers may collect their payments at the sellers settlements scene once their lot has been sold. In [15, 21, 13] we present an electronic auction house based on the traditional fish market metaphor. In a highly mimetic way, the workings of FM96.5 also involve the concurrency of several scenes governed by the market intermediaries identified in FishMarket. Therefore, seller agents register their goods with a ....

The first contribution we present is a new definition of dialogical institution, based on [5], which is formed by a dialogical framework and a performative structure. This definition allow us to instantiate a traditional institution, say a hospital, and model, for example, the existing medical protocolary procedures with the hospital managers, detailing what kind of agents exist and play ....
