Ambush Programming

Somewhat with little enthusiasm I marked today the recent exam for the semantic web course I had given this and previous year. What kept me going was the fact that this is not only the last exam for that particular course, but that it is also the last course for me, hopefully for a very long time.

The course had not been difficult or anything, quite pleasureable actually. And as usual I also experimented with new ways to explain stuff, new material, new tasks, and new exam question.

Throwing off Ballast (Part I)

As my interests shift I will have to jettison a few things.

My first (innocent) victim is the Semantic Web course I gave the last years at the local Technical University.

The last iteration was definitely smoother than the one before, both in terms of content and organisation. And dealing with students was quite fun.

  • 6.2.2009 10:56: I have just submitted the results of the exam (and the lab assignments) to the university. These will be posted at the usual place. On paper which is low-tech, but working. The results will be held back for a week or so, before they will be forwarded to the central administration.
  • 1.2.2009 16:54: Marking of exams is very cumbersome and slow. Still 4 questions are missing. Maybe some time next week.

ESW, Final Observations

Comments on the end term exam

The end result was quite good, given the fact that the questions were certainly not trivial and you did not have yet sample questions to practice on. Here is the statistics, almost equally spread over the spectrum.

Today I was poking around the Jena RDF Framework, mostly to figure out how one would use an OWL reasoner there.
