VerbNet
A hierarchical verb lexicon linking syntactic and semantic patterns for English verbs.

A corpus annotated with semantic propositions and predicate-argument relations.

The Proposition Bank (PropBank) is a corpus of text annotated with semantic propositions, focusing on predicate-argument relations. It builds upon the Penn Treebank by adding semantic role labels to the syntactic trees. Originally funded by ACE, it has expanded through NSF, DARPA GALE, and BOLT funding to include diverse genres such as broadcast news, webtext, and conversations. PropBank annotations are mapped to VerbNet and FrameNet via SemLink, providing a unified view of verb semantics. It also supports AMR annotation by unifying rolesets across parts of speech. The resource is maintained and released, with annotations from corpora like the English Web Treebank and clinical notes being incorporated when licensing allows. Annotations are produced at CLEAR under Martha Palmer's supervision.

Explore all tools that specialize in semantic role labeling. This domain focus ensures Proposition Bank delivers optimized results for this specific requirement.
Annotation of text with semantic roles, identifying the relationship between predicates and their arguments within a sentence. Uses PropBank frame files.
Identifies the core arguments associated with each predicate in a sentence, revealing who did what to whom. Essential component of PropBank.
A combined representation of PropBank, VerbNet, and FrameNet, allowing users to browse and compare semantic information across resources. Facilitates cross-resource querying.
PropBank provides frame files used in Abstract Meaning Representation (AMR) annotation, unifying rolesets across different parts of speech. Extends PropBank's utility to AMR tasks.
Adaptations of the English PropBank for other languages, including Chinese, Arabic, and Hindi. Enables cross-lingual semantic analysis.
