Token
In Data Science and Artificial Intelligence, a token refers to a sequence of characters that represents a unit of meaning for processing. Tokens are used in natural language processing (NLP) to break down text into smaller units for analysis. These units can be words, phrases, or even individual characters. Tokens are often created by removing punctuation and other non-essential characters from text, and then separating the remaining text into individual units. Tokens can be used for a variety of purposes, such as sentiment analysis, topic modeling, and text classification. They are also used in machine learning algorithms to represent text data in a numerical format that can be processed by computers.
