Pos Tagging

Part of Speech Tagging (POS Tagging) is a subtask in natural language processing aimed at automatically identifying the part-of-speech category of each word in a text, such as noun, verb, adjective, etc. This task provides foundational support for advanced processing like syntactic analysis and semantic understanding by labeling the grammatical function of words, and it is widely applied in areas such as machine translation, sentiment analysis, and information retrieval to improve the accuracy and efficiency of systems.
