ET-Space:
The Concept Space interface allows
users to search for documents directly
with keywords or access the concept
space for search term suggestion.
The concept space is an automatically
generated thesaurus based on word
co-occurrence both within individual
documents and within the collection
as a whole. The system can suggest
terms for searching as they appear
in the documents enhancing information
recall. The top 40 terms are displayed
in order based on a weighting/ranking
algorithm. Each concept space term
has an identifier that links it to
the source search term. The interface
allows the user to enter search terms
as a single word or a phrase and multiple
search terms may be entered. Clicking
on the box adjacent to a concept space
term will add it to your previous
search. You may then elect to see
more concept space terms or search
for documents.
ET-Map:
A 2-D multi-layered SOM was generated
from the entertainment collection.
Text labels and colors are used to
demarcate regions in the SOM, color
has no specific meaning. SOMs will
cluster similar categories near each
other on the map. Clicking on a map
region will take you down a layer
in a multi-layered map, or show you
the documents associated with that
category if the number of documents
is less than 200.
