Proposition Bank

  • 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 LDC.

  • PropBank today
  • This project was continued under NSF funding and DARPA GALE and BOLT. with the aim of creating Parallel PropBanks (the English-Chinese Treebank/PropBank) and also PropBanking other genres, such as Broadcast News, Broadcast Conversation, WebText and Discussion Fora, at the University of Colorado. PropBank is also being mapped to VerbNet and FrameNet as part of SemLink: Mapping together PropBank/VerbNet/FrameNet. PropBank's coverage is also being extended to provide support for AMR annotation, which makes heavy use of PropBank frame files. This is being funded by DARPA DEFT.
