Approach and Methodology
Testbed:
- CSQuest is a collection of 280,000 computer engineering terms and 10M links.
- Arizona Noun Phraser:
indexing based on the identification
of noun phrases in text.
- 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.
- Concept Space
Generation: Batch, Incremental,
Real-time
- 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.
- Ward's Hierarchical
Clustering: another method of categorizing
information.
- Visualization-magnification with Fisheye view or Fractal view.
