Been learning about Deterministic Finite Automaton, which is a kind of Finite State Machine. Humm. A trip to Wikipedia would have been worth more than two hours at school. Oh, well. Anyway, the subject is nice, and helped me understand more about the obscurities behind Regular Expressions.

In AI, been learning about Expert System. Again, a visit to Wikipedia would have been more valuable. :) This brought my attention to Prolog, which I've been always curious about, but never tried. I must admit that the concept behind fascinates me, and I've even dreamed about it last night. My dream was about using Prolog to build a knowledge base to then be exported to RDF, and also the inverse: Given a set of RDF definitions, transform them into a format that can be loaded into Prolog. I still have to figure out if this would be of any practical use though, as it seems the only advantage would be to use Prolog's internal predicate matching to find connections between subjects.

Another nice idea would be to convert from Prolog statements or RDF statements into graphviz dot format.

On a side note, GSS seems like a very very neat thing to try.

Update: It seems like IsaViz already uses graphviz and dot internally to generate the SVG that will then be imported. The fact that I came to the same idea shows that I was on the right track after all, the only difference being that I would implement it in Python instead of Java. :)
