LATHICAI Glossary

Generative AI & LLMs

Abstractive summarization

Making a shorter version of something by expressing its main points in new words.

Example

An assistant rewrites a long report as a short paragraph.

Why people use it

It can turn long writing into a shorter explanation with new wording.

What you'll hear

“Give me the main ideas in a short paragraph.”

What this means for you

Compare key claims with the source before relying on the summary.

Can you control it?

Sometimes

Sometimes. Your choices depend on the tool and your access. The settings available to an everyday user may differ from those available to the people running it.

Common questions

Can a summary sound clearer than the original?
Yes. Smooth writing can hide the uncertainty, disagreement or qualifications that appeared in the source.
Can it combine ideas from different passages?
Yes. That can make a summary clearer, but it can also create a connection the author did not make.
Will two summaries always emphasize the same points?
No. The request, audience and AI system can change which details receive attention.
