    <event:abstract><![CDATA[Automatic word sense discrimination is the process of distinguishing the 
number of unique senses of a target word in a given corpus. This work 
approaches word sense discrimination as an unsupervised clustering 
problem on the context of the target word in web documents.
Using the features from the computed clusters, the system constructs a 
new lexicon entry for the target word which includes the semantic and 
syntactic constraints for each discriminated sense. The lexicon entries 
are evaluated for precision and recall against sense inventories created 
from three human dictionaries.
This work:
<ul>
<li>Uses syntactic and semantic features not in the current word sense 
discrimination literature</li>
<li>Uses a corpus not in the current word sense discrimination 
literature (web documents)</li>
<li>Generates lexicon entries based on the results of word sense 
discrimination</li>
</ul>
