AI definitions: Extractive summarization

Extractive summarization - Identifying the important sections of a text and then producing a subset of sentences from that original text. On the other hand, abstractive summarization, uses natural language techniques to interpret and understand the important aspects of a text in order to generate a more “human” friendly summary. While abstractive summarization generates entirely new sentences that are sometimes not  in the source material, extractive summarization sticks to the original text. This is particularly helpful when accuracy and maintaining the author's original intent are the priority.
