> The recently rebuilt sentence detector (currently in trunk and the 3.1.0 branch) is sometimes
taking the apostrophe as a sentence break where the ctakes-3.0.0-incubating model didn’t.
> The training data used for the recently rebuilt model only contains only 7 lines that
end with an apostrophe (single quote) followed immediately by a newline
> It has >100K occurrences of 's
> It has >175K occurrences of the ' character in all.
> The place I noticed this is in testfakenote.txt.xml in ctakes-regression-test.
> The word "Broca's" used to have a ContractionToken but since a sentence is now ending
on the apostrophe, the apostrophe is getting annotated as a PunctuationToken.
> See more in the thread started at
> http://markmail.org/message/wavipejszlspzo5u
> including examples that split correctly and incorrectly.
