    Adaptable filter graphs – Towards highly-configurable query visualizations
    (INFORMATIK 2012, 2012) Haag, Florian; Raschke, Michael; Ertl, Thomas
    Systems for browsing and finding information in the vast amount of data available on the web keep growing in complexity. To alleviate this complexity for queries, various visualization techniques have been developed in the past. We have examined the filter/flow concept. This paper presents a transformation schema for filter/flow graphs to make them even more intuitively usable and to support distributed collaborative use. For that schema, several possibilities for transformating the visualization and various factors that may influence that transformation are discussed. Fi- nally, the schema is further explained based on a trip planning example scenario.

    Aspect grid: A visualization for iteratively refining aspect-based queries on document collections
    (Informatik 2014, 2014) Haag, Florian; Han, Qi; John, Markus; Ertl, Thomas
    Search results comprising of unstructured documents are traditionally displayed as plain lists, whereas the formulation of complex queries can be aided by comprehensive visualizations that highlight relevant attributes of the search results. We propose a visualization concept that incorporates a sentiment analysis of aspects mentioned in examined documents. Our concept provides a means of iteratively refining the query based upon preliminary search results. After an abstract description of the concept, we elaborate on its usage in a practical example of filtering customer reviews in order to choose a restaurant based on user-defined preferences.
