Sentiment analysis is a field within natural language processing (NLP) that aims to identify and extract subjective information from text. This information can be used to determine the sentiment of a piece of text, such as whether it is positive, negative, or neutral.

- Market Research: Understanding customer opinions about products and services.

How Does Sentiment Analysis Work?
Sentiment analysis typically involves the following steps:
- Text Preprocessing: This involves cleaning and preparing the text data for analysis. This may include removing stop words, stemming words, and converting text to lowercase.
- Feature Extraction: This involves converting the text data into a format that can be analyzed by a machine learning algorithm. Common techniques include bag-of-words models and TF-IDF.
- Machine Learning Model: A machine learning model is trained on labeled data to predict the sentiment of new text.
- Evaluation: The model is evaluated using test data to ensure its accuracy.
