CAFE (collaborative agents for filtering e-mails) is a multi-agent system to collaboratively filter spam from users' mail. CAFE associates each user with a proxy agent that acts as an interface between the user's e-mail client and the server. With the support of other agents, the proxy agent classifies messages into three categories: ham (good messages),(More)
CAFE (Collaborative Agents for Filtering E-mails) is a multi-agent system to collaboratively filter spam from users’ mail stream. CAFE associates a proxy agent with each user, and this agent represents a sort of interface between the user’s e-mail client (i.e. Microsoft Outlook, Eudora, etc.) and the e-mail server. With the support of other types of agents,(More)
This paper presents RAIS, a peer-to-peer multi-agent system for information sharing among a community of users connected through the Internet. RAIS offers a similar search power of Web search engines, but avoids the burden of publishing information on the Web and guaranties a controlled and dynamic access to information. The use of agent technologies has(More)

Peer-to-peer and service-oriented technologies have emerged as the dominant means for realizing scalable and interoperable distributed applications. This incontrovertible fact seems to nullify the expectation of multi-agent system researchers that agents could play a fundamental role in realizing such applications. However, from a deeper analysis, it is(More)
