Wouter Beek successfully defended his thesis "The ‘K’ in ‘Semantic Web’ stands for ‘Knowledge’" at the VU. He earned cum laude PhD, which happens to only about 5% of the computer science PhDs in the Netherlands!

Wouter's work depends to a large extend on the SWI-Prolog semantic web infrastructure. He contributed with many bug reports and patiently explained all the subtle things about the relevant W3C standards to me. In addition he developed the semweb/rdf11 library, providing a much cleaner API to deal with RDF than the original semweb/rdf_db. Wouter's contributions made the SWI-Prolog semantic web libraries robust and standard compliant. It is now to use them for expressing knowledge!

Wouter, congratulations and thanks for the (still ongoing) collaboration!

We're offering an 8 week course in SWI-Prolog.

It will cover not only the usual material of a basic Prolog course, but as much of the SWI-Prolog system as we can fit in what looks like it's going to be 8 very intensive weeks.

Starts June 8. The textbook will be Clocksin and Mellish, Programming in Prolog, using the ISO standard, 5th ed.

Version 7.6.1 has been released. Highlights:

  • Several race conditions in atom, functor and predicate `supervisor' installation have been fixed. Thanks to Keri, being a perfect detective! This work includes the installation of memory barriers, needed to avoid reordering memory access on e.g., ARM and powerpc.
  • Race condition in windows sockets. Keri.
  • Port: ARM: unsigned char issue in RDF Turtle parser. Added recognising ARM and powerpc in configure.ac to build by default as a shared object configuration.
  • Avoid unnecessary creation of modules for several built-ins.
