KN-AHS: An Adaptive Hypertext Client of the User Modeling System BGP-MS

Abstract

This paper describes the automatic adaptation of hypertext to the user's presumed domain knowledge in the KN-AHS system, and the support that the user modeling shell system BGP-MS can provide for this adaptation. First, basic hypertext concepts are introduced and reasons given for why hypertext should adapt to the current user (especially to his/her state of knowledge). The paper gives a brief overview of the representation and inference components of BGP-MS that are used by KN-AHS, followed by a description of its adaptive user interface. The interaction between the adaptive hypertext system and the user modeling system is investigated in detail based on a possible dialog with a user. Finally, the inter-process communication between KN-AHS and BGP-MS is described and related work discussed. The aim of this work was to demonstrate the feasibility of user modeling with BGP-MS in a normal and acute hardware and software environment that is frequently found in the workplace.
