Strategic knowledge in design: a compositional approach

In interactive design processes, strategic decisions are made at different levels. To support designers, design support systems need to include corresponding strategic knowledge at these levels. In this paper three levels of strategic interaction and strategic knowledge are identified within a compositional model of design. These levels are identified in reasoning about the manipulation of requ...

WebPersona: a lifelike presentation agent for the World-Wide Web

Rapid growth of competition on the electronic market place will generate the de mand for new innovative communication styles with web users In this paper we develop an operational approach for the automated generation of hypermedia pre sentations Unlike conventional hypermedia we use a life like presentation agent which presents the generated material and guides the user through a dynamically e...

Epsilon focusing--A strategy for active example selection

In most classical formulations of learning from examples, a passive learner is presented with examples randomly drawn. Here we discuss an-focusing strategy that actively choose examples for concept learning. We describe the local focused property that functions must have for such a strategy to work. Finally, we develop an example selection heuristic, motivated by-focusing, for training a comput...

A light-weight Web-at-a-Glance system for intelligent information retrieval

Web-at-a-Glance (WAG) is a system to assist the user in information retrieval and discovery by gleaning the most relevant information from a web site or several web sites. This paper presents this new approach for intelligent information retrieval from web sites, and describes the prototyping of the light-weight WAG system as an active index system. q 1998 Elsevier Science B.V.
