Text Mining
Text Mining is a way to analyze large amounts of written information to find useful patterns and insights. It's like having a smart assistant that can read through thousands of documents, customer reviews, or social media posts to understand what people are saying or find specific information. Companies use text mining to understand customer feedback, analyze market trends, or sort through research papers. You might also see it called "text analytics" or "text data mining." This is similar to data analysis, but specifically focused on working with written text instead of numbers.
