How to summarize text without losing its context
A practical method for keeping the decision, evidence, qualifiers and next action intact when shortening text.
A reliable summary keeps the source's central decision or claim, the evidence that supports it, material qualifiers, and the next action. Shortening is useful only after those four parts are identified.
Mark the four context anchors
Read once for meaning, then mark the claim or decision, the evidence, any condition that limits it, and the requested next step.
- Underline the main claim or decision.
- Circle evidence and numbers.
- Box exceptions, uncertainty and dates.
- Write the next action in the margin.
Choose extractive or abstractive summarization
Extractive summaries select source sentences and are easy to audit. Abstractive summaries rewrite ideas and can be smoother, but they introduce a larger risk of changing meaning.
Compress repetition before detail
Remove repeated setup and examples before removing qualifiers. A short caveat can matter more than a long illustration.
Run a reverse check
For every summary sentence, point to the source passage that supports it. If support is missing or weaker than the summary, revise the sentence.
Check the source against the result
The pilot reduced average review time from 18 minutes to 11 minutes across 120 documents. The sample excluded scanned PDFs, so the team will test OCR documents before a full rollout.
The pilot cut average review time from 18 to 11 minutes across 120 documents, but excluded scanned PDFs; OCR testing is required before rollout.
The shorter version keeps the measured result, sample size, exclusion and next action.
Use the four-part check on your own source
Create a local extractive result, then compare it with the decision, evidence, qualifier and next action.
