Universal Dependencies (UD) is a framework for consistent grammatical annotation across different languages. It provides a set of guidelines for representing the grammatical structure of sentences, focusing on the relationships between words. This helps linguists and researchers analyze and compare languages more effectively. The UD framework includes a standardized set of part-of-speech tags and dependency relations, making it easier to create multilingual resources. By using UD, developers can build better natural language processing tools, improving tasks like translation, sentiment analysis, and information extraction across various languages.
