Today we reached another thousand. After printing and resetting the report, I loaded POPfile's new version. I'll certainly keep you informed....
Continuing in the same format I used in my earlier note about PF:
Fourth Thousand
This test span ended November 21 at 1,000 messages.
- 26 (2.6%) were sent to the wrong bucket.
- 97.4% were sent to the right bucket....
- 415 (41.5%) were spam. Again: Wow!
- 4 (0.4%) were probably virus-laden.
- 4 (0.4%) were bounced email.
- Auction seems to be fully solved; 39 messages, with one false positive and one false negative.
- The Vendor category may have finally improved: 14 messages; only three errors.
- Lists looks better: Ten false positives and no false negatives associated with 51 messages.
- A new category, created (with my new e-mail address) to service this weblog, had 8 errors--to go with seven messages. New categories are always problems....
All in all, that's a rather impressive performance. The increasing spam count is also rather impressive; after all, I added this tool to my kit because the junk seemed to be getting out of hand.
The new POPfile version has a thoroughly-revamped back end, and some modifications to the code in the engine. We'll see how it goes.
Jon Udell's also talking about using Bayesian categorizers, at both a higher level of abstraction and greater detail. Worth a look.
