Abstract
A method for processing e-mails includes receiving a plurality of e-mails. For each e-mail in the plurality of e-mails, a feature representation is generated for an e-mail based on a set of noun phrases associated with the e-mail. A set of topics associated with the plurality of e-mails is generated based on the feature representation for each e-mail. Sentence structure associated with the e-mail and parts of speech associated with the e-mail may be determined. The parts of speech, including a set of noun phrases associated with the e-mail, may be used to generate the feature representation for the e-mail.
