Design prompts for extractive and generative Q&A with source grounding.
01 The Concept
Q&A systems combine retrieval with generation to answer questions accurately. Extractive QA pulls exact answers from documents; generative QA synthesizes answers from multiple sources.
02 Weak vs. Strong
EX 01Question Answering Systems Blueprint
Systematically implement question answering systems with validation and metrics.
→ Why it works
Structured question answering systems yields measurable quality improvements.
03 Key Points
01Extractive QA: Identifying exact answer spans within source documents.
02Generative QA: Synthesizing answers from multiple sources.
03Source grounding: Requiring answers to cite their source documents.
04Unanswerable detection: Recognizing when questions cannot be answered.
05Follow-up handling: Managing conversational Q&A with context carryover.
04 Model-Specific Notes
Claude excels at question answering systems with structured XML inputs.
05 For Your Role
Think of question answering systems as organizing your work so every step is clear.
