Abstract:
In one embodiment, a support vector machine is employed to compute a spam threshold and weights of tokens and heuristic rules. An incoming e-mail is parsed to determine if it contains one or more of the tokens. Tokens identified to be in the e-mail are then used to determine if the e-mail satisfies one or more heuristic rules. The weights of tokens found in the e-mail and the weights of the heuristic rules satisfied by the e-mail may be employed in the computation of a spam score. The spam score may be compared to the spam threshold to determine if the e-mail is spam or legitimate.
