Text Summarizer

In short A summary keeps the claims and the numbers and drops the elaboration, and which of those you keep depends on the format you ask for. A one-line summary has room for the single main claim and nothing else. Bullets suit text with several parallel points. A paragraph suits an argument, because it can carry the connective tissue that makes a conclusion follow from a premise, and bullets cannot. A structured brief suits a document someone will act on. The thing to check in any summary, machine-made or not, is the numbers: figures and dates are exactly what a summary is for and exactly what gets dropped or garbled first, so read them against the source. The second thing to check is whether a hedge survived. Source text that said a result "may indicate" something and a summary that says it "shows" it are different claims, and that shift happens constantly in condensed text. A summary that is more confident than its source is wrong even when every fact in it is right.
