    Adaptive Portals: Adapting and Recommending Content and Expertise
    (16th Workshop on Adaptivity and User Modeling in Interactive Systems, 2008) Nauerz, Andreas; Bakalov, Fedor; König-Ries, Birgitta; Welsch, Martin
    Today, Portals provide users with a central point of access to companywide information. Initially they focused on presenting the most valuable and widely used information to users providing them with quick and efficient information access. But the amount of information accessible quickly grew and finding the right information became more and more complex and time consuming. In this paper, we illustrate options for adapting and recommending content based on user- and context models that reflect users’ interests and preferences and on annotations of resources provided by users. We additionally leverage the entire communitys’ interests, preferences and collective intelligence to perform group-based adaptation. We adapt a Portal’s structure (e.g. navigation) and provide recommendations to be able to reach content being of interest easier. We recommend background in- formation, experts and users with similar interests. We finally construct a Portal’s navigation structure entirely based on the communitys’ behavior. Our main concepts have been prototypically embedded within IBM’s WebSphere Portal.

    Adaptive Treemap Based Navigation Through Web Portals
    (16th Workshop on Adaptivity and User Modeling in Interactive Systems, 2008) Nauerz, Andreas; Schindler, Sirko; Bakalov, Fedor
    Today, Portals most often present the navigation in form of tree-like structures to users. These trees follow a representation of data with a natural hierarchy. Single nodes are either parents or children. This representation style has several drawbacks: for reaching the leaves users have to traverse rather long paths. During the traversion of the tree users get often lost and, finally, the content relations remain unclear. It is not obvious where the ”most” content is located, too. We regard treemapping (a method for displaying tree-structured data using nested polygons) as a promising technology to overcome these draw- backs. We especially focus on adaptive treemaps displaying different treemaps to different users - always trying to satisfy each single users’ individual needs. Our main concepts have been prototypically embedded within IBM’s WebSphere Portal.

    Towards an Automatic Service Composition for Generation of User-Sensitive Mashups
    (16th Workshop on Adaptivity and User Modeling in Interactive Systems, 2008) Fischer, Thomas; Bakalov, Fedor; Nauerz, Andreas
    In today’s Web 2.0, mashups allow users to bring together data and services from various Web applications in order to create a new integrated tool that serves their needs. Nowadays, there is an increasing number of frameworks that provide users with a GUI environment to manually assemble different data sources and services into a mashup. However, in order to create such tools, the user must possess a certain level of technical knowledge. In this paper, we introduce a framework that automatically selects and combines Web services to create mashups. We also describe the user model that stores knowledge about user interests and expertise, which are used by the framework in order to generate mashups tailored to the needs of individual users.
