Photographs, illustrations, infographics, data visualizations, and general images help convey complex topics to a wide audience. The way that visual artifacts influence how readers form an opinion beyond the text is an important issue to research, but there are few works about this topic. In this context, we research the persuasive, emotional and memorable dimensions of data visualizations and illustrations in journalistic storytelling for long-form articles. We conducted a user study and compared the effects which data visualizations and illustrations have on changing attitude towards a presented topic. While visual representations are usually studied along one dimension, in this experimental study, we explore the effects on readers' attitudes along three: persuasion, emotion, and information retention. By comparing different versions of the same article, we observe how attitudes differ based on the visual stimuli present, and how they are perceived when combined. Results indicate that the narrative using only data visualization elicits a stronger emotional impact than illustration-only visual support, as well as a significant change in the initial attitude about the topic. Our findings contribute to a growing body of literature on how visual artifacts may be used to inform and influence public opinion and debate. We present ideas for future work to generalize the results beyond the domain studied, the water crisis.}, subject = {Journalismus}, language = {en} } @inproceedings{MenzelBludauLeitneretal., author = {Menzel, Sina and Bludau, Mark-Jan and Leitner, Elena and D{\"o}rk, Marian and Moreno-Schneider, Juli{\´a}n and Petras, Vivien and Rehm, Georg}, title = {Graph Technologies for the Analysis of Historical Social Networks Using Heterogeneous Data Sources}, series = {Graph Technologies in the Humanities}, booktitle = {Graph Technologies in the Humanities}, editor = {Andrews, Tara and Diehr, Franziska and Efer, Thomas and Kuczera, Andreas and van Zundert, Joris}, address = {Wien}, organization = {Universit{\"a}t Wien}, issn = {1613-0073}, pages = {124 -- 149}, abstract = {Over the last decades, cultural heritage institutions have provided extensive machine-readable data, such as bibliographic and archival metadata, full-text collections, and authority records containing multitudes of implicit and explicit statements about the social relations between various types of entities.

Emosaic is grounded in psychological research on the relationship between language, affect, and color perception. We capitalize on an established three-dimensional model of human emotion: valence (good, nice vs. bad, awful), arousal (calm, passive vs. exciting, active) and dominance (weak, controlled vs. strong, in control). Previously, multi-dimensional models of emotion have been used rarely in visualizations of textual data, due to the perceptual challenges involved. Furthermore, until recently most text visualizations remained at a high level, precluding closer engagement with the deep semantic content of the text. Informed by empirical studies, we introduce a color mapping that translates any point in three-dimensional affective space into a unique color. Emosaic uses affective dictionaries of words annotated with the three emotional parameters of the valence-arousal-dominance model to extract emotional meanings from texts and then assigns to them corresponding color parameters of the hue-saturation-brightness color space. This approach of mapping emotion to color is aimed at helping readers to more easily grasp the emotional tone of the text. Several features of Emosaic allow readers to interactively explore the affective content of the text in more detail; e.g., in aggregated form as histograms, in sequential form following the order of text, and in detail embedded into the text display itself. Interaction techniques have been included to allow for filtering and navigating of text and visualizations.}, subject = {Mensch-Maschine-Kommunikation}, language = {en} } @inproceedings{BludauHallingHollyetal., author = {Bludau, Mark-Jan and Halling, Thorsten and Holly, Eva Maria and Wieloch, Jasmin and Schnaitter, Hannes and Balck, Sandra and Plakidis, Melina and Rehm, Georg and Fangerau, Heiner and D{\"o}rk, Marian}, title = {Was sehe ich?
