摘要：Many corpora have been tagged and parsed with different tagging and
parsing schemes and are not mutually usable because of such differences.
The main aim of a mapping is that parsed corpora with different
annotations can be changed to a version which is annotated with the
required scheme so as to extend the research resources. In other words,
the mapping between annotation schemes will enable the reusability of
the resources of the existing tagged and parsed corpora.
