Content 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, including education, journalism, and business, to help readers quickly grasp the core message without having to read the entire text. There are two main types of content summarization: extractive summarization, which selects key sentences from the original text, and abstractive summarization, which generates new sentences to convey the main points. Both methods aim to improve comprehension and efficiency in information consumption.
