Saturday and Sunday I played around with info action. I wanted to display the spam status for old revisions without reclassifying them and without using cached information.

IMHO there were the options:

1. Using a separate log for the classification status of a page at save time

2. Using meta data for the status. The meta data should be checked only for old revision (!=current). This approach has some problems, one of them is that the meta-data entry (Eg. spamstatus) should be protected by the SecurityPolicy otherwise it could be modified by users.

The goal of the info action changes is to provide functionally similar to the "exchange stock quotes" shown on financial websites. Which of the two options would be the most appropriate ? Or is there another way ? I think that I would prefer option No. 1 -- MarianNeagul 2007-06-17 22:17:17

• Where would be the right place to implement the classification features ? Reimar suggested to do the classification in PageEditor class and to use the Page class for retrieving the classification. The approach Reimar suggested would allow us to use this features in all parts of MM (that use Page or PageEditor).

• The classification system should be plugin based (plugin for spam filtering, general text classification) ?
• In my opinion the current aplications of the system would be:

  • The classification results form Page and PageEditor could be used to enforce a policy, via SecurityPolicy, based on the contents of pages (Eg. deny posting spam), the same way as in Skip's initial patch

  • The themes could use them to display some relevant data for the specific page (Similar pages - based on content, classification, tags, etc.)
  • A macro could be used to enable the user to classify/tag a page

• Another, spam specific, idea would be to use some kind of distributed spam filter. Something like SpamCop, spamhouse or DCC do for mail servers. Or a collaborative filter (is privacy a issue for us?). Does MM need something like this ?

• Can you summarize the characteristics of wiki spam and spammers ?

• Text classification: supervised or unsupervised ?!
