- Clustering can be done for terms and/or documents, if the
collection has the right characteristics (which can be tested for).
- Reasonably fast and space efficient clustering algorithms
exist, and today's computer systems can run them on most common
collections.
- Selection of the proper clustering algorithm for a collection
can probably be based on findings of research mentioned. Some
algorithms can refine such a clustering, if some particular
operation needs to be supported specially, such as for frequent runs.
- Improvements in browsing, retrieval efficiency, and in
some cases retrieval effectiveness, can result from clustering.
