    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.

    Software solutions for form-based, mobile data collection – A comparative evaluation
    (BTW 2019 – Workshopband, 2019) Steinberg, Markus; Schindler, Sirko; Klan, Friederike
    Many citizen science projects rely on their contributors going to the field and collecting data. Due to their wide availability and increasing capability, modern mobile devices have become an indispensable tool to ease the collection process. Projects can publish mobile apps, that allow contributors to easily collect data and submit their results. The requirements of individual projects oftentimes overlap to a large extent, which triggered the development of multiple generic frameworks. They allow new projects to quickly generate customized apps and reuse existing infrastructure. However, the wide landscape of tools with diverging capabilities requires projects to compare and choose. This report supports data managers in making an informed decision. We report on our experiences primarily on the whole data collection workflow starting from setting up your own instance to finally analyzing the retrieved data. We compare eight tools – both free and commercial – according to the features provided and difficulties encountered.
