The Penn Treebank

The Penn Treebank is a large, expertly annotated collection of written and spoken language data used to teach computers how to understand and process human language. It includes sentences from news articles, books, and conversations, marked with detailed grammatical information such as parts of speech and sentence structure. This enables researchers and developers to build more accurate language models and natural language processing tools, improving applications like speech recognition, translation, and text analysis. Essentially, it serves as a foundational resource that helps computers better grasp the complexities of human language.
