A Penny for your thoughts: New Year wishes from mechanical turkers

I wanted to learn more about Amazon’s Mechanical Turk service (wikipedia), and perhaps also figure out how I feel about it. Named after a historical faked chess-playing machine, it uses the Web to allow people around the world to work on short low-pay ‘micro-tasks’. It’s a disturbing capitalist fantasy come true, echoing Frederick Taylor’s ‘Scientific [...]

Disambiguating with DBpedia

Sketchy notes. Say you’re looking for an identifier for something, and you know it’s a company/organization, and you have a label “Woolworths”. What can be done to choose amongst the results we find in DBpedia for this crude query? PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#> select distinct ?x where { ?x a <http://dbpedia.org/ontology/Organisation>;  rdfs:label ?l . FILTER(REGEX(?l, “Woolworths*”)). [...]

Subject classification and Statistics

Subject classification and statistics share some common problems. This post takes a small example discussed at this week’s ODaF event on “Semantic Statistics” in Tilberg, and explores its expression coded in the Universal Decimal Classification (UDC). UDC supports faceted description, providing an abstract grammar allowing sentence-like subject descriptions to be composed from the “raw materials” defined [...]

WOT in RDFa?

(This post is written in RDFa…) To the best of my knowledge, Ludovic Hirlimann‘s PGP fingerprint is 6EFBD26FC7A212B2E093 B9E868F358F6C139647C. You might also be interested in his photos on flickr, or his workplace, Mozilla Messaging. The GPG key details were checked over a Skype video call with me, Ludo and Kaare A. Larsen. This blog post [...]

WordPress trust syndication revisited: F2F plugin

This is a followup to my Syndicating trust? Mediawiki, WordPress and OpenID post. I now have a simple implementation that exports data from WordPress: the F2F plugin. Also some experiments with consuming aggregates of this information from multiple sources. FOAF has always had a bias towards describing social things that are shown rather than merely [...]

WordPress, TinyMCE and RDFa editors

I’m writing this in WordPress’s ‘Visual’ mode WYSIWYG HTML editor, and thinking “how could it be improved to support RDFa?” Well let’s think. Humm. In RDFa, every section of text is always ‘about’ something, and then has typed links or properties associated with that thing. So there are icons ‘B’ for bold, ‘I’ for italics, [...]

Syndicating trust? Mediawiki, WordPress and OpenID

Fancy title but simple code. A periodic update script is setting user/group membership rules on the FOAF wiki based on a list of trusted (for this purpose) OpenIDs exported from a nearby blog. If you’ve commented on the blog using OpenID and it was accepted, this means you can also perform some admin actions (page [...]

Remote remotes

I’ve just closed the loop on last weekend’s XMPP / Apple Remote hack, using Strophe.js, a library that extends XMPP into normal Web pages. I hope I’ll find some way to use this in the NoTube project (eg. wired up to Web-based video playing in OpenSocial apps), but even if not it has been a [...]
