Abstract
Abstract. More and more users work simultaneously with multiple applications, to perform various tasks. This situation puts high demands on the user adaptive systems (UAS), which traditionally support users ’ work in a single isolated domain, and which now shift towards personalization in multi-task and crossapplication contexts. In their attempt to meet the increasing demands, UAS grow in complexity, but they do little about their compatibility and interoperability. We propose a Component-based Architecture for UAS: (CompAS). The key feature of CompAS is modularization of knowledge models and as a consequence allowing existing UAS to share their user models by means of a centralized user model service. As a proof of concept we show how two existing applications, AHA! [1] and UserModelService [2] can achieve interaction based on the extracted user model.
