AI Definitions: Abstractive Summarization

Abstractive summarization (ABS) – A natural language processing summary technique generating new sentences not found in the source material. In contrast, extractive summarization sticks to the original text, identifying the important sections to produce a subset of sentences taken from the original text. Abstractive summarization is better when the meaning of the text is more important than exactness while extractive summarization is better when sticking to the original language is critical.
