What does summarization mean?
Summarization is the process of expressing the central ideas of a longer text, speech, recording, or account in a shorter form without losing the essential information. It is used in education, journalism, business, law, and computer science, where readers or listeners may need to understand a lengthy source quickly. A good summarization selects and compresses the most important points rather than merely repeating sentences from the original. The word can refer either to this process or, less commonly, to the shorter account produced. In everyday use, “summary” is often more natural, while “summarization” emphasizes the procedure, technique, or act of condensing material. In technology, automatic summarization refers to software systems that generate condensed representations of documents, audio, or video.

Where does summarization come from?
Summarization comes from the verb summarize, which was borrowed in the early 19th century from Latin summarizare, meaning “to sum up” or “include in a summary.” That verb was formed from Latin summa, meaning “the highest part” or “total,” from which English also derives summary and summation. The suffix -ation, common in English for forming nouns from verbs, was added to create summarization.
