> Clustering is the problem of automatically organizing a large data
> collection by partitioning the data into clusters, so the objects in  
> the
> same cluster are more similar to one another than to objects in other
> clusters. Textual document clustering aims at organizing the  
> documents of
> a collection in a way that results in better search without  
> introducing
> much extra cost and complexity. For instance, clustering strategies  
> have
> been investigated in Information Retrieval to support alternative
> organizations of the search results. In this talk I'll present a  
> study of
> possible application of a recently proposed clustering method, named
> Dynamic Quantum Clustering (DQC), to the problem of document  
> clustering.
> This method works by analogy by considering data samples as  
> particles that
> obey physics laws. In our case particles are the documents of the
> collection. Some initial results will be presented. These results  
> analyze
> the capability of the DQC to select highly relevant documents  
> relative to
> a query of a user.
