  abstract = {In groupware or community based applications the user
 interface is usually static or tailored to the individual user’s
 needs. Newer developments try to adapt the user interface
 automatically in regard to user contexts. Even though these
 techniques are proven useful, there exists no contextadaptive
 system taking the current context of a group or
 community in regard. In this paper, we briefly discuss the
 problems of defining context and present our understanding
 of context as a subset of the current information state. We
 provide an exemplary scenario to present different
 approaches how to compute group contexts based on
 semantic models and user contexts, and the consequences
 for the adaptation goals - in the interface or through
 changes at system functionalities or tools. We additionally
 discuss the problems occurring at evaluating adaptations
 and the value of group context for collaborative work.},

We present briefly an own context-understanding, a multi-layered framework for context-based adaptation. We present some current examples for context-based adaptation and conclude with some further thoughts about adding unstructured information such as tags to our context understanding to be able to mediate knowledge between different contexts and users.},

  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.}

  abstract = {Collaborative work is characterized by frequently changing situations and corresponding demands for tool support and interaction behavior provided by the collaboration environment. Current approaches to address these changing demands include manual tailoring by end-users and automatic adaptation of single user tools or for individual users. Few systems use context as a basis for adapting collaborative work environments, mostly focusing on document recommendation and awareness provision. In this paper, we present, firstly, a generic four layer framework for modeling and exploiting context. Secondly, a generic adaptation process translating user activity into state, deriving context for a given focus, and executing adaptation rules on this context. Thirdly, a collaboration domain model for describing collaboration environments and collaborative situations. Fourthly, examples of exploiting our approach to support context-based adaptation in four typical collaboration situations: co-location, co-access, co-recommendation, and co-dependency.},

Context views aim at identifying the most important elements within an application in a generic way by exploiting context information.}

RecFlows (Kurzform für Recommendation Workflows) stellt eine Reihe etablierter Algorithmen aus dem Bereich Recommender Systems zur Verfügung sowie einen Workflow-Mechanismus, um aus diesen Algorithmen flexibel hybride Recommender zu erstellen. Darüber hinaus werden unterschiedliche Sensoren bereitgestellt, um Informationen aus verschiedenen Quellen in den Empfehlungsprozess mit einfließen zu lassen. Insbesondere werden Sensoren zur Kontext-Erfassung (z. B. der aktuelle Ort des Nutzers anhand seiner IP-Adresse) implementiert. So ist es möglich, mit Hilfe von RecFlows hybride, kontextsensitive Empfehlungen zu generieren.
