and supports IOB, IOE, IOBES and IO (also known as plain) tagging schemes.

There are three chunk types(named entity types) including PER(person), ORG(orgnazation)

Since the calculations actually use label ids rather than labels, extra attention
should be paid when mapping labels to ids to make CheckEvalOp work. The key point
is that the listed equations are satisfied by ids.
