Study Notes

Regular Expressions

A specific chapter of the book is dedicated to regular expressions.

Tokenization in NLP

Tokenization is a process in natural language processing (NLP) that breaks down text into individual units called tokens.
The purpose of tokenization is to prepare text data for further analysis or processing.

Subword Tokenization

Subword tokenization is a type of tokenization that breaks down words into smaller units called subwords.
Subword tokenization is used to handle out-of-vocabulary (OOV) words or words with rare characters.

Method for Subword Tokenization

The method used for subword tokenization is based on the WordPiece algorithm.

Word Normalization

Word normalization is a process in NLP that transforms words into a standard form.
The purpose of word normalization is to reduce the dimensionality of the feature space and to improve the accuracy of NLP models.
