What is the process of automatically identifying and extracting specific pieces of text or information from a larger document or source?

• A. Text generation
• B. Text extraction
• C. Text mining
• D. Text synthesis

Answer: (B)

Automatically identifying and extracting specific pieces of text from a larger document is a task in information extraction. This focuses on locating the relevant bits—such as names, dates, amounts—and pulling them out in a structured form. That’s why text extraction is the correct choice: it is the process dedicated to pulling out exact pieces of information from raw text. Text generation, on the other hand, is about producing new text. Text mining seeks patterns and insights across large collections of text rather than isolating particular fields. Text synthesis involves creating or combining text as well. For example, pulling out the total, date, and vendor from a receipt is a typical extraction task.
