[Corpora-List] sentence boundary detectors

[Armin Schmidt]

Dear list,

I was wondering if you could point me to good sentence splitters for the
following languages: German, Russian, Spanish, English. It would be
great if they were stand-alone programs or modules for Python (Perl
would be ok, too ... although I'm already aware of the respective
CPAN-modules for English and German).

Since I do have corpora in all the above mentioned languages I would
also be very interested in available implementations (not papers) of any
unsupervised learning methods for detecting sentence boundaries (or
rather abbreviations).

Thanks,
Armin
