In this chapter, the classification performance of latent semantic indexing (LSI) applied to the task of detecting and filtering unsolicited bulk or commercial email (UBE, UCE, commonly called “spam”) is studied. Comparisons to the simple vector space model (VSM) and to the extremely widespread, de-facto standard for spam filtering, the SpamAssassin system, are summarized. It is shown that VSM and LSI achieve significantly better classification results than SpamAssassin.
