I just sent my new Sesame RDF repository a query using my new Python wrapper for its REST API:

fhs.getQuery('fhs', 'rql', 'typeOf( https://feinsteinhs.org/teacher#Geller )')

Which translates roughly to What kind of thing is my wife?

Since I had loaded her completed evaluations and the foaf RDF Schema into the repository, I knew it would tell me she was a foaf:Person. I was also knew that it knew about RDF, and that as far as it is concerned, she is a rdf:Resource, even though there is some ongoing philosphical debate about the meaning of that statement. I was, however, somewhat taken aback that it also told me that she is a geo:SpatialThing. Who told my computer about the physical universe? I have apparently delved deeply enough into the Semantic Web to hit the AI part.

Kinda creepy. What do the Laws of Robotics look like in RDF?

Continuing the trend for gruesome TV adverts, here are a few suggestions:

• Persil Ultra — a fanged, tentacled monstrosity attacks joggers who haven't washed their tracksuits.
• Shredded Wheat — Ian Botham's skin peels off to reveal he's made of the cereal.
• Halifax — armies of zombies in a graveyard sing the praises of life insurance.

Come on, directors, there are still depths of horror yet to be explored.
