  abstract = {User centered design and development of interactive systems utilizes theoretically well-grounded, yet practical ways to capture user’s goals and intentions. Task models are an established approach to break down a central objective into a set of hierarchical organized tasks. While task models achieve to provide a good overview of the overall system, they often lack detail necessary to (semi-) automatically generate user interfaces. Based on requirements derived from a comprehensive overview of existing task model extensions, improvements and development methods, an approach that integrates logical rules with task models is introduced. By means of practical examples it is shown, that the integration of rules enables advanced execution flows as well as leaner task models thus improving their practical value.},

  abstract = {Mobile computing and new input methods have increased the need to create multiple interfaces for one functional core. Automatic generation of user interfaces attempts a solution for this problem. Existing approaches either generate interfaces on the base of a detailed task model or use domain models in conjunction with interface specific annotations and transformation rules. While task models are very time consuming to create and cannot easily be reused domain models lack the flexibility for use cases which are not covered or in conflict with used transformation rules. Based on an overview of existing approaches this paper sets out a conceptual framework which combines both task model and ontology based concepts. It is shown that the proposed combination leads to more abstract and reusable task models.},

  abstract = {Es gibt eine Vielzahl an adaptiven Systemen, Frameworks oder Modellen, die den Anspruch aufstellen, generisch Anwendbar zu sein. Ist eine Evaluation oder Validierung derartiger Systeme ohnehin schon anspruchsvoll, so ist der Nachweis der generellen Anwendbarkeit eine noch größere Herausforderung. In diesem Artikel werden vier Use-Cases vorgestellt, mit denen derartige Ansätze auf ihre allgemeine Anwendbarkeit hin untersucht werden können. Ist es möglich, alle vier Szenarien mit dem Ansatz abzubilden bzw. umzusetzen, so kann der Anspruch auf allgemeine Anwendbarkeit aufrecht erhalten werden.}

We derive a model for context-adaptivity from the well-established one for user-adaptivity proposed by Jameson, and introduce context views as means for facilitating group-based work. Context views aim at identifying the most important elements within an application in a generic way by exploiting context information.}
