treebank

A treebank is a structured collection of sentences that have been carefully analyzed to show how words relate to each other in terms of grammar. Imagine each sentence is broken down into its parts—like subjects, verbs, and objects—and connected with lines that depict their relationships. These connections form a tree-like diagram, which helps computers understand language patterns. Treebanks are valuable for developing language technology, such as translation or speech recognition, by providing a detailed syntactic map of language usage based on real examples.
