GSLT ILP Practical 2

Grab this gzipped tar archive, and save it somewhere.
If necessary, untar it with tar zxvf gisw.tgz. This will put all the files in a directory called prac2.
Start up sicstus and read in sys.pl. This will pull in the other Prolog files. Answer p to any questions about redefining predicates.
Do | ?- test.

This should generate a load of parses for some test sentences. The code for test/0 is in sys.pl if you want to have a look at it.

Kill sicstus and then comment out the vp_vp_mod rule from medium_grammar.pl
Restart the system by reading sys.pl into sicstus again.
Have a look at the sentences in the file asent.
Do | ?- read_sentences(asent).
Now that we have our sentences read in, let us generate rules from attempted parses of them. Do | ?- generate_rules_from_sentences.
Before we look at these rules more slowly, let's re-order them so the more interesting ones come up first. Do | ?- order_by_coverage.
Do | ?- display_rules.
Play with the options to look at sentences covered by the various rules and the associated parses.
