What is tokenization and how does it relate to sentiment analysis?

Tokenization is the process of breaking down text into smaller units, called tokens. These tokens can be words, phrases, or even characters. In sentiment analysis, tokenization helps in analyzing the sentiment of each token to determine the overall sentiment of the text.

Can you give me an example of tokenization?

Sure! For the sentence 'I love AI!', tokenization would break it down into the tokens: ['I', 'love', 'AI', '!']. Each of these tokens can then be analyzed for sentiment.

How does sentiment analysis work after tokenization?

After tokenization, each token is analyzed using algorithms that assign sentiment scores. These scores help determine if the overall sentiment is positive, negative, or neutral.

What tools can I use for tokenization and sentiment analysis?

There are several tools available, such as NLTK, SpaCy, and TextBlob for Python, which can help with both tokenization and sentiment analysis.
