The Semantic Web Command Line

mhausenblas — Wed, 20 Feb 2008 22:28:14 +0100

Ever have wondered if there is something around like a command line for the Semantic Web? An online tool that allows you load and query a range of data sources? Well, peradventure Benjamin Nowack has developed a tool, called SPARQLBot, that does all this. It is really great. You launch your favourite IRC client (I use Hydra IRC) and then you (or a SPARQL geek near to you) defines a command that does something useful. Pull in some data, query it, smush it, etc.

Check it out! Play around with it. Experience how to instant-integrate data source on an RDF-basis. You will enjoy it. An example may better illustrate it: Imagine you've joined the #sparqlbot channel at irc:irc.freenode.net; you query for news (from an RSS channel):

mhausenblas>sparqlbot, load <FEEDURI>
mhausenblas>sparqlbot, news about XXX

What happens in the background is that the feed gets loaded into the store, and the command triggers a SPARQL query:

SELECT DISTINCT ?item ?o WHERE {
?item a rss:item ; ?p ?o .
FILTER REGEX(?o, "$1", "i")
}

Isn't that great? I experienced it today. It really rocks :) You can add your own commands (given some basic SPARQL knowledge) and extend the bot's intelligence. Not to mention that this nice tool (being based on ARC2) even understands RDFa - very nice, indeed (try also the 'sw faq command'). However, the name SPARQLBot is to modest, IMHO. It is THE Semantic Web command line!

Steve O'Hear has put together a nice piece about current IPTV applications entitled 8 Internet TV apps in 8 weeks.

Microformats aren't an answer to the Sem...

I can see many valid things in Keith's post about uF and the Semantic Web (like 'Things have URIs'), but I like most his conclusion:

So in other words, Microformats are not, in themselves, building, or contributing to, the semantic web. They can be made to join the semantic web, but this requires extra effort on the part of individual authors – it does not come ‘for free’ when ‘doing microformats’.

Explaining Wikis and RSS (video)

mhausenblas — Wed, 30 May 2007 20:55:56 +0200

Quoting Brady Forrest on O'Reilly Radar:

At various times I have had to explain what a wiki is to people and I rarely do a good job. In the future I may just show them Lee & Sachi LeFever's video Wikis in Plain English. It does a really good job of explaining why and how someone would want to us a wiki. They doing a good job of keeping the vocabulary on the easily-understood side of tech. If you ever need to explain RSS they have a video for that too.

RDFa news

Mark Birbek explains how to use RDFa in XHTML 1 - STOP - The RDFa specification (incl. Primer, Syntax, Use Cases, and Test Suite) is on its way - STOP - Bob DuCharme has a nice article that introduces RDFa step by step - STOP - Benjamin Nowack wrote a form-based, semi-automatic comparison matrix for RDFa, eRDF and microformats.

Ookles - Semantic Media ?

Reading a review of a new media service called Ookles (to be launched soon) that among other things offers facial and object recognition and an automatic organization of your photos + some kind of intelligent automatic tagging for your media, I am eager to see it working ... and might want to know what kind of technology they use?

BTW: Ookles = Flickr+Riya+YouTube ...
