Lab 4: Context Precision & Recall

Did retrieval find the right chunks? Precision checks for noise. Recall checks for missing information.

📌Context Precision

Of what we retrieved, how much was actually useful? Irrelevant chunks dilute the context and confuse the LLM.

Precision = useful_chunks / total_chunks

📡Context Recall

Of everything needed to answer, how much did we find? Missing facts lead to incomplete or hallucinated answers.

Recall = covered_sentences / total_sentences
