James Joseph Masanz closed CTAKES-227.
--------------------------------------
> Broca's -> PunctuationToken instead of ContractionToken - caused by
> apostrophe seen as sentence ending
> ------------------------------------------------------------------------------------------------------
>
> Key: CTAKES-227
> URL: https://issues.apache.org/jira/browse/CTAKES-227
> Project: cTAKES
> Issue Type: Bug
> Components: ctakes-core
> Affects Versions: 3.1
> Reporter: James Joseph Masanz
> Assignee: James Joseph Masanz
> Fix For: 3.1
>
>
> 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.
