What is text analysis?

Text analysis, also known as text mining, is the process of automatically extracting valuable information from text data. It involves techniques like sentiment analysis (determining the emotional tone of text), topic modeling (identifying the main themes in a collection of documents), entity recognition (locating and classifying named entities like people, organizations, and locations), and text summarization (creating concise summaries of longer texts). Text analysis is commonly used for understanding customer feedback, monitoring brand reputation, performing market research, and improving search engine accuracy, among many other applications.
