Treebank

TreebankIt is a deep processing corpus that can be used to segment sentences, tag parts of speech, and annotate syntactic structure relationships.

Classification of Treebank

Treebanks can be roughly divided into two categories: phrase structure tree banks and dependency structure tree banks.

• Phrase structure tree library: generally describes sentences using their structural components;
• Dependency structure tree library: built according to the dependency structure of sentences.

The role of treebanks

• Provide data and platform for automatic parsers;
• Provide real text annotation materials for syntactic research;
• The basis for labeling semantic items and semantic relations of words within sentences.
