Text Tokenization

Character tokenization

Character tokenization is a text transformation technique that divides text into individual or group characters. Unlike other types of tokenization that split text into words or phrases, character tokenization treats each character as a separate token. This technique is essential when working with languages that do not use spaces between words or when analyzing text at a more granular level. For example, we use character tokenization in Chinese or Japanese to break down text into individual characters, which can help analyze the language’s structure and identify specific characters or patterns.

Let’s review the code line by line:

• Line 3: We load data from the reviews.csv dataset.

• Line 4: We then apply a function that converts each review text into a list of characters and save the result to the new character_tokens column.

• Line 5: Lastly, we display the new character_tokens column ...
