Agents in multiagent systems interact to a large extent by communicating. Such communication may be fruitfully studied from the point of view of speech act theory. In order for mul-tiagent systems to be formally and rigorously designed and analyzed, a semantics of speech acts that gives their objective model-theoretic conditions of satisfaction is needed. However , most research into multiagent...

This paper presents, a new agent model “specially” designed for the new Android Google SDK, where the Android mobile phone can be considered as a software agent. This agent model has an approach more practical than theoretical because it uses abstractions which makes possible its implementation on differents systems. The appearance of Android as an open system based on Linux has created new exp...

In this paper a theory of delegation is presented. There are at least three reasons for developing such a theory. First, one of the most relevant notions of "agent" is based on the notion of "task" and of "on behalf of". In order to found this notion a theory of delegation among agents is needed. Second, the notion of autonomy should be based on different kinds and levels of delegation. Third, ...

For more than a decade it has been taken for granted that social choice theory can inform the design of multiagent systems (narrowly construed). I challenge this common point of view by surveying papers that support it and identifying common pitfalls. I also propose a way forward and present some key challenges. Ultimately, my goal is to spark a rethinking of the theory and practice of multiage...

Web sites are public representations of corporations, businesses and governmental bodies. As such they require proper maintenance to ensure that accurate and updated information is presented adequately. Dynamically created Web sites sometimes are not an option: they add a computational overhead on the server and make the automatic indexing of pages difficult. Static Web sites may grow to an ext...

Background: There is an information gap in literature regarding postoperative outcome of total knee arthroplasty (TKA)in patients with hardware in-situ from the previous knee surgery. The present study aims to evaluate impact of retainedhardware on short-term outcome of TKA patients.Methods: Perioperative radiographs of patients who had undergone TKA between 2007 and 2012 were reviewedand patie...

We present the application of software process modeling and simulation using an agent-based approach to a real case study of software maintenance. The original process used PSP/TSP; it spent a large amount of time estimating in advance maintenance requests, and needed to be greatly improved. To this purpose, a Kanban system was successfully implemented, that demonstrated to be able to substanti...

This paper describes a story-telling agent which is itself a multi-agent system composed of a blackboard structure and a number of smaller agents which both cooperate and compete against each other to preemt information according to each one’s point of view. The agent architecture is b~ed on a cognitive model, Minsky’s Society of Mind. The story-telling agent is an example application of this a...

Several knowledge management issues arise during the life-cycle of an interactive system. During the design phase software engineers need to acquire from users and domain experts knowledge about what they need and about the intended use of the interactive system. Subsequently, due to the phenomenon of user and system co-evolution, users modify their needs and/or their ways of using the system: ...
