Acknowledgements
We wish to acknowledge the contributions of the following institutions and individuals:
- Center for the Management of Information (CMI) and Dr. Jay Nunamaker for their support and the use of the GroupSystems session outputs.
Approach and Methodology
Testbed:
- 200 raw Group Systems (GS) electronic meeting comments.
Techniques:
- Automatic Indexing-stop wording and algorithmic index phrase formation
- Concept Space-index phrase co-occurrence information is used to generate an automatic thesaurus for search term suggestion.
- Kohonen Self-Organization Map (SOM) Algorithms-1-D, 2-D, 3-D (VRML) displays for information categorization and visualization.
- Multi-dimensional Scaling-an alternative method to the Kohonen SOM providing information categorization and visualization in 1-D, 2-D, 3-D (VRML) displays.
