Process of deriving tokens

Sentences are formed by stream of words and from a sentence we need to derive individual meaningful chunks which are called the tokens and process of deriving token is called tokenization:

• The process of deriving tokens from a stream of text has two stages. If you have a lot of paragraphs, then first you need to do sentence tokenization, then word tokenization, and generate the meaning of the tokens.
• Tokenization and lemmatization are processes that are helpful for lexical analysis. Using the nltk library, we can perform tokenization and lemmatization.
• Tokenization can be defined as identifying the boundary of sentences or words.
• Lemmatization can be defined as a process that identifies the correct intended POS ...
