Abstract
A method and apparatus for clustering documents from a set of documents includes issuing a request from an electronic device for documents which are relevant to the request. The documents believed to meet the request requirements are identified and the documents are thereafter supplied to a document clustering system. The document clustering system forms clusters of the documents by operation of the clustering system. A robustness criterion, by analogy with self-assembled physical systems, is applied to select the best, most robust, clustering. Robust clusters have a higher designability feature than other clusters which are generated where designability refers to a number of ways a particular cluster can be formed.
