Introduction to Text Mining

Text Mining, also known as text data mining or text analytics, refers to the process of extracting valuable information from text. It involves the discovery by computer of new, previously unknown information, by automatically extracting information from different written resources. A key element is the linkage of the extracted information together to form new facts or new hypotheses to be explored further by more conventional means of experimentation. Text Mining uses a variety of methodologies from natural language processing, statistics, and machine learning to analyze textual data for patterns, trends, and insights. For example, text mining can help in sentiment analysis to gauge public opinion on certain topics, extract specific data from legal documents, or identify trends and patterns in customer feedback, enabling businesses to improve their services or products.
