Linked Literature, Linked TV – Everything Looks like a Graph

Ben Fry in ‘Visualizing Data‘: Graphs can be a powerful way to represent relationships between data, but they are also a very abstract concept, which means that they run the danger of meaning something only to the creator of the graph. Often, simply showing the structure of the data says very little about what it actually […]

XMPP untethered – serverless messaging in the core?

In the XMPP session at last february’s FOSDEM I gave a brief demo of some NoTube work on how TV-style remote controls might look with XMPP providing their communication link. For the TV part, I showed Boxee, with a tiny Python script exposing some of its localhost HTTP API to the wider network via XMPP. […]

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*”)). […]

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 […]

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 […]

What kind of Semantic Web researcher are you?

It’s hard to keep secrets in today’s increasingly interconnected, networked world. Social network megasites, mobile phones, webcams and  inter-site syndication can broadcast and amplify the slightest fragment of information. Data linking and interpretation tools can put these fragments together, to paint a detailed picture of your life, both online and off. This online richness creates […]

goo go opensocial

The Japanese portal / search engine goo, have gone live with their Shindig-based OpenSocial container. See example user page, goo labs site, developer’s kitchen and documentation (in Japanese). See also announcement from Eiji Kitamura on the shindig (Apache opensocial) list.

Flickr & MusicBrainz Machine tags: If you’ve got it, flaunt it

From Sander van Zoest at Uncensored Interview, a convention for representing MusicBrainz identifiers using Flickr’s Machine Tag mechanism. Example: A photo of Matthew Dear, tagged as follows: musicbrainz:mbid=3d191c12-be64-4f90-94d8-ac324b2b3544 wikipedia:en=Matthew_Dear It also includes a Wikipedia identifier which could be used to link to DBpedia (though this might duplicate information also available within MusicBrainz’s advanced relationships system). […]

Facebook problem statement

People want full ownership and control of their information so they can turn off access to it at any time. At the same time, people also want to be able to bring the information others have shared with them—like email addresses, phone numbers, photos and so on—to other services and grant those services access to […]

FRBR and W3C Media Annotations

Just spotted this review of FRBR (Functional Requirements for Bibliographic Records) in the group’s wiki. Also some interesting notes on modelling. It seems the Media Annotation work is starting out well, both in terms of the analysis they’re performing, the relationships they’re seeing (FRBR is from the Library world and often passed over by industry […]

Problem statement

A Pew Research Center survey released a few days ago found that only half of Americans correctly know that Mr. Obama is a Christian. Meanwhile, 13 percent of registered voters say that he is a Muslim, compared with 12 percent in June and 10 percent in March. More ominously, a rising share — now 16 […]
