On how to write rules in Constraint Grammar (CG-3) - VISL

CG rules
➢ rules add, remove or select morphological, syntactic,
semantic or other readings
➢ rules use context conditions of arbitrary distance and
complexity (i.e. other words and tags in the sentence)
➢ rules are applied in a deterministic and sequential way,
so removed information can't be recovered (though I t
can be traced). Robust because:
rules in batches, usually safe rules first
last remaining reading can't be removed
will assign readings even to very unconventional language input (“nonchomskyan”)
