We propose building blocks and their concrete implementation to leverage Research 2.0 practice and technologies in our field, including a publication feed format for exchanging publication data, a RESTful API to retrieve publication and Web 2.0 data, and a publisher suit for refining and aggregating data. We illustrate the use of this infrastructure with Research 2.0 application examples ranging from a Mash-Up environment, a mobile and multitouch application, thereby demonstrating the strength of this infrastructure.}, subject = {Open Science}, language = {en} } @article{GarretonMoriniCelhayetal., author = {Garret{\´o}n, Manuela and Morini, Francesca and Celhay, Pablo and D{\"o}rk, Marian and Parra, Denis}, title = {Attitudinal effects of data visualizations and illustrations in data stories}, series = {IEEE Transactions on Visualization and Computer Graphics}, journal = {IEEE Transactions on Visualization and Computer Graphics}, address = {New York}, organization = {Institute of Electrical and Electronics Engineers (IEEE)}, issn = {1077-2626}, doi = {10.1109/TVCG.2023.3248319}, pages = {1 -- 16}, abstract = {Journalism has become more data-driven and inherently visual in recent years. 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} }
