The NLP pipeline is a concept that describes the various steps required to process natural language. It starts with the input of text, followed by tokenization to divide the input into individual words and smaller parts. This is followed by the morphological process, which involves analyzing the words and their structure. This is followed by the syntactic process, where words are processed according to their role in a sentence. After the syntactic process comes the process of semantics, in which the meaning of the words is decoded.
