Attempts to filter unsolicited bulk email (‘spam’) tend to present two kinds of errors. Some unobjectionable messages are mistakenly flagged as spam (false positives), while some spam is not flagged (false negatives).
This seminar will start with discussion of the reasons why this problem is fundamental and why it has proven difficult to solve. It will also cover research methods aimed at quantifying the scope of the errors and at comparing their prevalence in competing email filtering systems.
The seminar will conclude by comparing email filtering errors with the mistakes made by web filtering systems, with a view towards identifying and adopting best practices in web filtering to make email filtering more accurate.
