What is Overview of Part-of-Speech Tagging about?

Part-of-speech tagging involves assigning lexical categories such as noun or verb to each word in a text. While early systems divided words into 8 categories, modern tagsets contain over 40 tags. Tagging accuracy has improved from baseline methods that assign each word its most frequent tag (90% accuracy) to current systems that use machine learning and features from neighboring words to achieve over 97% accuracy. However, tagging unknown and ambiguous words remains challenging.
