A method of organizing electronic document-related information at least
includes generating a collection of electronic documents, forming from
the collection, at least one cluster of documents based upon a user's
selection of a subject, and determining for each author of documents in
the cluster, the number of times each the author is an author of a
document corresponding to the subject. The authors are ranked and
presented to the user in the form of an index. The ranked index can be
interpreted as a ranking of subject matter experts.
