Hi Golda,

about allowing 'anyone to say anything about anything' we are working with Olga Streibel from Freie Universitšt Berlin, and others, on a concept called "Extreme Tagging". You can tag urls (as usual) but also the tags themselves, for example, a media resource representing the close-up of a car and identified by a url may be tagged with "car", "wheels" and "travel".  The tag "wheels" itself may then be tagged (possibly by a different user) with "car" and "wheel", and the tag "car" could itself be tagged with "vehicle". We also assume that the operation of tagging introduces a relation, not only a functional one (something has been tagged with this tag by somebody) but also a meaningful one (for some reason somebody tagged something with this tag). Therefore users can also tag relations between tags, to follow the example the following tags can be added: ("wheel", {"singular-of"},"wheels"), ("wheel", {_},"wheels"), ("car", {"is-a"},"vehicle"). This representation allows to collaboratively acquire knowledge paths between two elements, for example, between two "tags", "John Boorman" and "Terry Gilliam" we learn that:

[("John Boorman", {directed}, "Excalibur"),
("Excalibur", {about}, holy-grail) ,
(holy-grail, {similar-to}, grail), 
(grail, {topic-of}, "http://www.imdb.com/title/tt0071853/"),
("http://www.imdb.com/title/tt0071853/", {has-title}, "Monty Python and the Holy Grail"),
("Monty Python and the Holy Grail", {directed-by}, "Terry Gilliam")]

Social control mechanism such as the rating of relations will be introduced in order to control spam and favour meaningful statements. No sparql endpoint or RDF export yet as we just started working on the concept 2 weeks ago. A *very* alpha prototype can be found here (you need a Facebook account):


Bookmarklets are a great idea and are on the way, please drop me a line if you are interested in the project

Hi Golda,

Yes, this is really nice idea that has gained some traction in the Web2.0 world with sites like StumbleUpon and Lijit. It would be *very* interesting to see a Semantic Web reworking of the concept.

As Chris points out, http://revyu.com/ has many of the required components in place already. We have a bookmarklet that people can use to review resources on the Web (or things described by resources on the Web - the nature of the relationship between resource and web page is defined at review-time).

We don't allow arbitrary annotations other than reviews (text and numerical rating) and keyword tags, but in the first instance that might be sufficient. All this information is available via the SPARQL endpoint, and the trust-based features are close to being ready. 

So, it would be pretty easy to implement a bookmarklet or browser plugin that checked Revyu.com for any reviews of the currently viewed Web resource (or things related to that page) and showed this to the user. If you're interesting in investigating this further please do get in touch; we'd be very happy to work with you in getting this implemented.

Drop me an email off-list and we can talk some more :)
