- 12. YOUR PAPERS
- 14. Graph Summarized Responses • Nice algorithm (I will steal it!) • Not completely sure about visualization • Compare it with a predefined response? • Could use the textual clustering
- 16. High-order Clustering of Tags • Again, nice algorithm • The usefulness (by itself) is not clear • Automatic classification / directory?
- 18. Collaborative Writing Analysis • Simple yet effective! • Comparison with a desired concept map? • Summarization could add value • Make it a plugin for Google Docs (please!)
- 20. Programming Discussion Forums • Nice algorithm again • Not sure about the usefulness as it is • How about making question and finding previous answers? • Collaboration with other papers
- 22. Interactive Surfaces • Nice visualization • Reflection, but for what? • Highlight patterns using Process Mining • Animate the process (for teacher)
- 24. Competence-Based Structure • I am presenting a project with a similar idea • Graph simplification is an issue • Process Mining could help • Could use some uncertainty visualization :)
- 25. Conclusions • Opportunities for Collaboration (SIG) • Need to move more towards Visual Analytics • Evaluation is critical
