]> 2004-07-20T13:00:00-05:00 The vision has not yet materialized. Was it an example of an AI dream or "irrational exuberance" of the dot com era. I'll argue that the vision is still a good one and will describe how two new components might re-invigorate it. The first is the semantic web -- "an extension of the current web in which information is given well-defined meaning, better enabling computers and people to work in cooperation." The second is emergence of pervasive computing environments with requirements that multiagent systems are well suited to address. The argument will be illustrated using examples of current research at UMBC.]]>
