Let me disseminate this user study participation request.
Daniela Oelke, David Spretke, Andreas Stoffel, and Daniel A. Keim need to evaluate their research in the domain of visual analytics for improving the readability of a text. They would like to invite you to participate in a small survey that can be found here:
Your task will be to read twice through 5 sentences and rank them. Afterwards you are asked to state your reasons for ranking them the way you did. Completing the study should take no longer than 10-15 minutes. Your effort is really appreciated as it helps us to further improve their algorithms.
To know more about their algorithms, check e.g.: "Visual Analytics: Combining Automated Discovery with Interactive Visualizations".
