BERT Tokenizer

BERT Tokenizer is like a tool that breaks this sentence into smaller parts called “tokens.”

Here’s how it works:

Breaking the Sentence: The BERT Tokenizer takes each word in the sentence and separates it into its own token. So, “The” becomes one token, “big” becomes another token, and so on.

Handling Punctuation: It also deals with punctuation. For example, “quickly” and “park” are separate tokens, but the period at the end of the sentence is its own token too.

Special Tokens: BERT Tokenizer adds special tokens at the beginning and end of the sentence. These tokens help the computer understand where the sentence starts and stops.

Counting Tokens: After breaking the sentence into tokens, the Tokenizer counts how many tokens there are. In our example sentence, there would be 10 tokens.

Why is this important?

Well, it helps computers process and understand text more easily. Each token represents a piece of the sentence, and by breaking it down like this, the computer can analyze and make sense of the language.
