The Original PropBank
The original PropBank project, funded by ACE, created a corpus of
text annotated with information about basic semantic
propositions. Predicate-argument relations were added to the syntactic
trees of the Penn Treebank. This resource is now available via
This project was continued under NSF funding and DARPA GALE and
BOLT. The most well-known of these modern resources are the pointers
released under The Ontonotes 5, which expanded to other
genres, such as broadcast news, webtext, and conversation, more recent
annotations with the funding of DARPA-BOLT, NIH and Google have annotated SMS conversations,
corpora of questions, the English Web Treebank, and even clinical notes. When licensing allows,
the PropBank annotations of these corpora will be released and maintained here. Propbank annotation is done at CLEAR
under the supervision of Martha Palmer
Propbank Frame development
PropBank has also been mapped to VerbNet and FrameNet as part of SemLink: Mapping
together PropBank/VerbNet/FrameNet, and one can browse a combined representation of those
three resources at the Unified Verb Index. PropBank's coverage has also
been extended to provide support for AMR annotation (which uses PropBank frame files), unifying Propbank rolesets across different parts of speech. This is being funded by DARPA under the DEFT project.
For more information regarding frames, consult the history of the frame releases, or
of the changes in the new 3.0 Propbank frames. A corresponding DTD file is included in each frame release.
