Summarisation Strategies

What it is

Summarisation strategies are techniques for condensing long content to fit within context limits or reduce costs. These include hierarchical summarisation (summarise sections, then summarise summaries), extractive methods (pull key quotes), and progressive summarisation (multiple passes at different detail levels).

Why it matters

Working with long documents often requires summarisation. Different strategies suit different needs—extractive for preserving exact wording, abstractive for capturing meaning concisely. Understanding these strategies helps you process documents that exceed context windows effectively.
