Summarization is the process of condensing a larger piece of information into a shorter version while retaining its main ideas and essential details. This technique is commonly used in various fields, such as education, journalism, and research, to help readers quickly grasp the core message without having to read the entire text. Effective summarization involves identifying key points, eliminating unnecessary details, and rephrasing the content in a clear and concise manner. Tools like text summarization algorithms and note-taking techniques can assist individuals in creating accurate summaries, making it easier to study or communicate complex information.
