Some notes on the StarSEM 2012 shared task.

Training data

3,640 sentences with 989 instances of negation.

99 instances have no scope; 101 instances have a discontinuous scope that is not bridged by the cue.

371 instances have no event; 14 instances have discontinuous events. In 6 instances the event lies outside of the scope---these seem to be annotation errors:

• ... only an unambitious one who abandons a London career for the country ...

• ... an unjustifiable intrusion, ...

• It never recovered from the blow, ...

• "But I cant forget them, Miss Stapleton," said I.

• *... and means to *spare **no **pains or expense to restore the grandeur of his family. **

• Coming down with an un**signed warrant. **

Collins' coverage of the training data is 99.4%. **

Collins can't lemmatise contractions, e.g. can't = <unknown> **

Some examples
