1. A method for processing electronic mail comprising:
- computing a probability that a text string in an electronic mail message refers to an attachment as a function of a stored probability value for each of a plurality of sequences of words within the text string; and
where the email message lacks an attachment, prompting a user if the computed probability indicates that the text string refers to an attachment.

Abstract
A method for processing electronic mail includes computing a probability that a text string in an electronic mail message refers to an attachment as a function of a stored probability value for each of a plurality of sequences of words within the text string. Where the email message lacks an attachment, the method includes prompting a user if the computed probability indicates that the text string refers to an attachment.

16. A system for processing electronic mail comprising:
-
a statistical language model which stores probability values for a plurality of text sequences; and
a processor which executes instructions for retrieving stored probability values from the statistical language model for a plurality of text sequences in the email message and computing a probability that that the electronic mail message refers to an attachment as a function of the retrieved probability values. - View Dependent Claims (17, 18)

19. A computer program product comprising:
-
a computer-usable data carrier storing instructions that, when executed on a computer, cause the computer to perform a method comprising;
computing a probability that a text string in an electronic mail message refers to an attachment as a function of a stored probability value for each of a plurality of sequences of words within the text string; and
where the email message lacks an attachment, prompting a user if the computed probability indicates that the text string refers to an attachment.

20. A method for processing electronic mail comprising:
-
analyzing words of at least one text string of an electronic mail message with a statistical language model to determine whether the text string has at least a threshold probability of referring to an attachment; and
where the email message lacks an attachment and the text string is determined to have at least the threshold probability that the text string refers to an attachment, prompting a user.

21. A method for developing a statistical language model comprising:
-
establishing a first set of probability values for sequences of words found in a first corpus of sentences of electronic mail messages which are determined to refer to an attachment as a function of a frequency of their occurrence in the first corpus; and
establishing a second set of probability values for sequences of words found in a second corpus of sentences of electronic mail messages which are determined not to refer to an attachment as a function of a frequency of their occurrence in the second corpus.
