Models/Algorithms Trade-offs

Academic Risk + Uncertainty + Control

YOUR PAPERS

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

High-order Clustering of Tags

• Again, nice algorithm

• The usefulness (by itself) is not clear

• Automatic classification / directory?

Collaborative Writing Analysis

• Simple yet effective!

• Comparison with a desired concept map?

• Summarization could add value

• Make it a plugin for Google Docs (please!)

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

Interactive Surfaces

• Nice visualization

• Reflection, but for what?

• Highlight patterns using Process Mining

• Animate the process (for teacher)

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 :)

Conclusions

• Opportunities for Collaboration (SIG)

• Need to move more towards Visual Analytics

• Evaluation is critical
