YouTube - Using the Semantic Web to stop Linkspam

This is the presentation I gave to the World Wide Web Consortium TPAC in November. The basic idea is mark the comment areas of your blog so that Web crawlers that read it can tell what parts you wrote and what might be from a link spammer.



This has some interesting and important consequences for the blog ecology. Commenters become first class participants, search engines can easily and securely locate all the comments made by a single individual across multiple sites. Meta-moderation becomes possible and so on.
