The author developed an automatic text categorization approach and investigated its application upon categorizing emails. The categorization approach is derived from an instanced- based learning method that explores conditional probabilities of particular words. The effectiveness of the author's categorization approach using collections from a set of emails is then evaluated and assigned a numerical score based upon precision and recall. Precision was 65% while recall was 17%. The author's experiments indicated automatic categorization of incoming emails at the client level can categorize email, but is difficult when not using a standardized corpus. Word frequency is valuable, but should be used in combination with other methods such as phrase extraction for a higher level of performance.Naval Postgraduate School Monterey CA is the author of 'Automatic Text Categorization Applied to E-Mail', published 2002 under ISBN 9781423548836 and ISBN 1423548833.
