abstract
In modern hypertext systems, adaptation support for users in dynamically-changing environments will be essential to meet the needs of mobile users. In this paper, we introduce context-aware Trellis (caT), which supports flexible user (or agent) adaptation to a changing environment by incorporating both high-level Petri net features, such as structured tokens, and user modeling. It also integrates a fuzzy logic tool to support fuzzy (or uncertain) knowledge representation.
