Abstract

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.

Claims

1. A method of organizing electronic document-related information comprising:

forming at least one cluster of electronic documents based upon a user'"'"'s selection of a subject;

identifying each author of the documents in said cluster and accumulating a number of times each identified author is an author of a document in the cluster of electronic documents corresponding to said subject;

ranking each identified author according to the number accumulated for each identified author; and

presenting the rankings for the identified authors in an index form.

2. The method of claim 1, further comprising;

searching documents hyperlinked to the cluster of electronic documents; and

modifying the number of times accumulated for an author with a number of citations for the identified author in the hyperlinked documents pertaining to said subject.

3. The method of claim 1, further comprising;

searching documents hyperlinked to the cluster of electronic documents; and

modifying the number of times accumulated for an identified author by a number of times the identified author is an author of a hyperlinked document pertaining to said subject.

4. The method of claim 1, wherein said cluster of electronic documents is formed from documents stored at a specified World Wide Web domain.

5. The method of claim 1, wherein said cluster of electronic documents is formed from documents stored at a specified Intranet.

6. The method of claim 1, wherein said cluster of electronic documents is formed from documents managed by an identified server.

7. The method of claim 1, wherein said cluster of electronic documents is formed from a specified directory of documents.

8. The method of claim 1, wherein said cluster of electronic documents is formed from documents stored on the World Wide Web.

9. The method of claim 1, further comprising:

receiving user input specifying a frequency of citation threshold; and

excluding an author from the index when the accumulated number of times for an identified author is less than said specified frequency of citation threshold.

10. The method of claim 1, further comprising:

excluding from said accumulated number of times for an identified author documents that are redundant in content but stored in a format different than the format of a document previously counted.

11. The method of claim 1, further comprising:

excluding from said accumulated number documents that are redundant in content but stored in a repository different than a repository in which a document previously counted is stored.

12. The method of claim 2, further comprising:

excluding from said accumulated number documents that cite documents previously counted.

13. The method of claim 1, further comprising:

forming a second index for each identified author, the second index containing a number of times a document corresponding to the selected subject and having the same author is cited in another document by the identified author.

14. A system for organizing electronic document-related information comprising:

a document cluster former for forming at least one cluster of electronic documents based upon a user'"'"'s selection of a subject;

an author counter for identifying each author of a document in said cluster and accumulating the number of times each identified author is an author of a document in the cluster corresponding to said subject;

an author ranker for ranking each identified author according to the number of times accumulated for the identified author; and

an author indexer for sorting the identified authors into an index.

15. The system of claim 14, wherein a subject matter expertise of the identified authors corresponds to the sorting of the identified authors in the index.

16. The system of claim 14, further comprising:

a hyperlink document searcher for searching documents hyperlinked to the cluster of documents; and

the author counter counts a number of times an identified author is cited in a hyperlinked document pertaining to said subject.

17. The system of claim 14, further comprising:

a hyperlink document searcher for searching documents hyperlinked to the cluster of documents; and

the author counter counts a number of times an identified author is an author of a hyperlinked document pertaining to said subject.

18. The system of claim 14, wherein said cluster of electronic documents is formed from documents stored at a specified World Wide Web domain.

19. The system of claim 14, wherein said cluster of electronic documents is formed from documents stored on a specified Intranet.

20. The system of claim 14, wherein said cluster of electronic documents is formed from documents managed by a specified server.

21. The system of claim 14, wherein said cluster of electronic documents is formed from documents stored in a specified directory.

22. The system of claim 14, wherein said cluster of electronic documents is formed from documents stored on the World Wide Web.

23. The system of claim 14, further comprising:

a frequency of citation threshold receiver for receiving a frequency of citation threshold; and

the author indexer excludes an identified author from the index when the accumulated number of times for an identified author is less than the received frequency of citation threshold.
