The lack of external control over an agent's decisions, resources and actions hamper the usage of traditional transaction and workflow technology to make self-interested agents cooperate, i.e., agents cannot not be forced from a mediating cooperation instance to continue a cooperation. The challenge is, therefore, to design a cooperation mechanism that motivates cooperating agents to carry out a specified contract and, in case of unilateral defection, ensures that none of the cooperators can benefit from the situation. In this paper we present a domain independent framework how non-enforceable cooperations can be made safe against unilateral defection. We have developed a utility-based scheduling algorithm that keeps a cooperation in equilibrium and that motivates agents to continue a cooperation as long as it is for all participants beneficial.","PeriodicalId":106219,"journal":{"name":"Proceedings. 3rd IFCIS International Conference on Cooperative Information Systems (Cat.

The authors present a model for representing contexts in information bases along with a set of operations for manipulating contexts. These operations support creating, updating, combining, and comparing contexts. The model contributes to the efficient handling of information, especially in distributed, cooperative environments, as it enables (i) representing (possibly overlapping) partitions of an information base; (ii) partial representations of objects, (iii) flexible naming (e.g. relative names, synonyms and homonyms), (iv) focusing attention, and (v) combining and comparing different partial representations. The work advances towards the development of a formal framework intended to clarify several theoretical and practical issues related to the notion of context. The use of context in a cooperative environment is illustrated through a detailed example.","PeriodicalId":106219,"journal":{"name":"Proceedings. 3rd IFCIS International Conference on Cooperative Information Systems (Cat.

We investigate the issue of client data caching in the WAN environment. In the WAN environment, it is common that many clients are clustered in some local area, connected to each other over a LAN, and often request the same data to the same remote server. To take advantage of such a characteristic, we considered a client group-server DBMS architecture, in which the clients connected over a LAN in each local area form a client group and communicate with the server via a broker, a special client that belongs to the group and maintains cache consistency in its group on behalf of the server. We propose the data caching scheme called ICCC (Inter-Client Communication Caching) that fits the client group-server DBMS architecture. In ICCC, cached data can be shared among clients within the group through inter-client communication under the intervention of their broker. We conducted simulation experiments to evaluate the performance of ICCC. The results showed that ICCC considerably outperformed the standard callback locking scheme employed in the WAN environment.","PeriodicalId":106219,"journal":{"name":"Proceedings. 3rd IFCIS International Conference on Cooperative Information Systems (Cat.
