Corpora: learning regular expression patterns

[Chapman, Wendy]

Dear list members:

I would like to do some work on learning regular expression patterns from
text. Brill's paper "Pattern-based disambiguation for natural language
processing" in the EMNLP-VLC 2000 proceedings describes an interesting
algorithm. Has anybody implemented Brill's or other regular expression
learning algorithms? Any information on what types of
ambiguities people have applied regular expression learning to? Is there by
any chance an
available implementation?
