Tokenization is a preprocessing step in the NLP pipeline that precedes POS tagging, parsing (syntactic/semantic), and semantic analysis, making it a prerequisite for downstream structural processing.

Summary

Before the system can figure out what role each word plays, how sentences are structured, or what things actually mean, it first has to split raw text into individual pieces like words and punctuation. This means tokenization is the gate that everything else waits on; if that step goes wrong, the structural and semantic analysis built on top of it is built on sand.
