RDF Inferencing

June 28th, 2004 1:34 AM

On the drive to and from Maine, I was thinking about the information that I could pull out of all the RDF I’ve generated (RDF for pictures, weblog, beer, etc.).

I’m not sure how useful it would be in practice, but I like the idea of being able to infer location of people based on the RDF. For example:

(?img foaf:depicts ?person) (?img foaf:based_near ?location)(?person foaf:based_near ?location).

Usually. And restricted to the date the picture was taken.

I enjoy the idea that it can be inferred that I was in Maine on June 26th, 2004, or that I was probably in Ireland on June 5th, 2003, because I was there on June 3rd and June 7th.

This pattern would probably also apply to foaf:maker on pictures and my (hackish) dao:consumed on Beer. Maybe I’ll code up simple (date, person) ⇒ location and (date, location) ⇒ people mappings, and integrate them into the Image Search.


I haven’t read this in a while, so I decided to check it out. And the first thing I see is:

“On the drive to and from Maine, I was thinking about…(?img foaf:depicts ?person) (?img foaf:basednear ?location) ⇒ (?person foaf:basednear ?location).”

Apparently, I need to work on my conversational skills somewhat.

Also, that quote you show’d me this morning has inspired me to get a journal. I just hope I have the discipline to stick with it.

Well, some of the time you were sleeping (or at least being silent with your eyes closed), and the other times, the RDF stuff was competing with other tasks such as talking with you, trying to remember state and country capitols, and trying to drive.
