Real-world context is messier than our test datasets - DRUID proves it

This paper introduces DRUID, a dataset that tests how well LLMs actually use real-world context in retrieval tasks, revealing synthetic test data often misrepresents real scenarios.

Original Problem 🤔:

Current studies of how LLMs use retrieved context rely on artificial datasets that don't reflect real-world complexity. This limits our understanding of true RAG performance.

-----

Solution in this Paper 🔍:

→ Created DRUID dataset with real-world claims and evidence from fact-checking scenarios

→ Developed a new metric called ACU (Accumulated Context Usage) to measure how well LLMs utilize context

→ Compared DRUID against synthetic datasets like CounterFact and ConflictQA

→ Analyzed multiple context characteristics including relevance, stance, readability, and source reliability

-----

Key Insights from this Paper 💡:

→ Synthetic datasets exaggerate context characteristics rare in real retrieved data

→ Real-world contexts are more complex, longer, and have more uncertainty markers

→ Memory conflicts occur less frequently in real scenarios (58%) vs synthetic ones (97%)

→ Source characteristics matter more than individual context properties

→ LLMs show different behavior patterns with real vs synthetic contexts

-----

Results 📊:

→ Synthetic datasets show inflated context utilization scores

→ Real-world context usage patterns differ significantly from synthetic test results

→ Llama shows better context usage than Pythia across all datasets

→ Context-repulsion is rarer in realistic scenarios
