Summarization Purpose Create effective summaries by matching summarization type to purpose, audience, and context. "Summarize" can mean many different things—this skill helps identify and execute the right approach. Core Principle Summarization is translation, not just reduction. Different purposes require different summary types. Clarify the need before condensing. Clarifying Questions Before summarizing, consider: 1. Purpose: What will this summary be used for? Decision making Background information Further research Quick understanding Reference/recall 2. Audience: Who will read it? Technical experts General audience Decision makers Familiar/unfamiliar with topic 3. Scope: How comprehensive? Ultra brief (single sentence) Brief (paragraph) Moderate (page) Extended (multiple pages) 4. Emphasis: What aspects are most important? Methodology Findings/results Arguments/claims Context/background Implications/applications 5. Format: What structure? Narrative text Bullet points Hierarchical outline Visual representation Summary Type Taxonomy Information Reduction Approaches Type What It Is When to Use Key Point Extraction Isolating the most important claims Original has discrete important points Abstraction Higher level statements covering multiple details Patterns matter more than specifics Gisting Capturing essential meaning, discarding details Only core message matters Compression Shortening while preserving information Comprehensive coverage needed in less space Structural Approaches Type What It Is When to Use Executive Summary Business focused: decisions, recommendations, outcomes Documents requiring action Abstract/Précis Academic: methodology and findings Research papers, technical documents TLDR Ultra brief main takeaway Casual communication, extreme brevity Outline Hierarchical structure of main/supporting points Logical structure matters Purpose Oriented Approaches Type What It Is When to Use Synthesis Combining multiple sources coherently Summarizing across documents Critical Summary Evaluating claims while condensing Assessment of quality needed Contextual Summary Framing within broader knowledge Understanding bigger picture matters Actionable Summary Focusing on implications and next steps Summary will drive action Execution by Type Key Point Extraction 1. Scan for topic sentences and conclusions 2. Identify explicitly stated main ideas 3. List each distinct point 4. Preserve original phrasing where powerful Example: "The author makes three main arguments: (1)..., (2)..., (3)..." Abstraction 1. Group related details 2. Find common themes or patterns 3. Create higher level statements 4. Reduce specifics to principles Example: "Multiple studies consistently show..." instead of listing 12 studies Gisting 1. Ask: "What is the one thing to remember?" 2. Distill to core insight 3. Remove all supporting detail 4. Verify essence is preserved Example: "Remote work increases productivity for most knowledge workers." Executive Summary 1. State the problem/opportunity 2. Present the solution/recommendation 3. Highlight key benefits 4. Note costs/risks 5. Specify required actions Synthesis 1. Read all sources 2. Identify common themes 3. Note contradictions 4. Find complementary information 5. Create unified narrative Example: "Across the five reports, three key trends emerge..." Critical Summary 1. Summarize the claims 2. Evaluate the evidence 3. Assess methodology 4. Note limitations 5. Conclude with assessment Example: "While the author claims X, the evidence is limited by..." Format Variations Quotation Based Use key phrases verbatim When precise wording is important Select and organize most important quotes Bullet Points Break continuous text into discrete units When quick scanning is valued Make each point standalone Progressive Summary Start ultra brief Add layers of detail Let reader choose depth Comparative Summary Side by side analysis Highlight similarities and differences When contrasting sources Quality Checklist [ ] Purpose is clear [ ] Audience is considered [ ] Scope is appropriate [ ] Emphasis matches needs [ ] Format serves purpose [ ] Core message is preserved [ ] Reduction is proportional [ ] No invented information [ ] Attribution where needed Anti Patterns The Information Dump Problem: Reduces length but not complexity Fix: Focus on what matters, not just what's short The Distortion Problem: Changes meaning through compression Fix: Verify summary against original claims The One Size Fits All Problem: Same approach for all requests Fix: Match type to purpose and audience The Over Abstraction Problem: Loses all useful specifics Fix: Preserve concrete details that support understanding Integration Points Inbound: When asked to summarize any content When processing long documents When creating documentation Outbound: To decision making processes To knowledge management systems To communication outputs Complementary: speech adaptation : For spoken summaries voice analysis : For maintaining voice in summaries
