Abstract
In this chapter, we discuss the contribution of visualization research to the CRETA project. We give a definition of visualization as we conduct it as partners within the context of the project. Then, we introduce the opportunities and challenges of collaboration in interdisciplinary projects involving visualization research and delineate a number of conflicting requirements that need to be balanced in such a setting. The workflow pipeline that is defined by the concept of reflected text analytics can be separated in two phases, roughly subsumed under the notions ‘annotation’ and ‘interpretation’. For each of these phases, we present one approach that supports the respective analysis tasks by means of interactive visualization: an approach dealing with text annotation data by multiple annotators and an approach dealing with networks of characters in narrative texts. We describe the representation and interaction features of these approaches and exemplify their workings in a series of usage scenarios. Finally, we assess our experiences in developing these approaches with respect to the balancing of requirements mentioned above.
