Summarization

As explained in Microsoft Azure in Action

Summarization is the generation of a shorter representation that preserves the main information in a source text.

Summarization turns a longer text into a shorter version that keeps its main information. A bookstore could use generated book summaries to help customers decide which titles to explore. section 7.1

Summarizing can also help when a source is too large to fit into a model’s context window. Think of that window as a fixed-size suitcase: pack the text down, split it into chunks, or retrieve only the relevant pieces. Test the chosen model for speed, cost, and quality before putting it to work. section 7.1

How Microsoft Azure in Action covers it

How deep it goes
Explains the purpose through a suitcase analogy but does not work through a summary prompt or assess summary quality.
Examples
Uses generated book summaries for customer discovery and an oversized book or conversation as a context-limit example.
What you can do after
Evaluate/understand when a shorter text could aid book discovery or reduce input size for a model.
How it connects
Links summarization to context windows, chunking, retrieval, model choice, and prompts.
