observationsingle paperReviewed by AI

On forecasting next-year music festival lineups (link prediction between artists and festivals), zero-shot LLMs prompted for ranked candidate lists score far below specialized temporal-knowledge-graph forecasting models trained on the domain graph, and their errors are dominated by popularity bias toward globally famous artists plus duplicate entries in the ranked list.

Capability: Predicting future events

Observed on

380 German festivals, 1971-2025 yearly TKG, single-step prediction of 2025; LLMs tested were Llama 3.1 8B, Llama 3.3 70B (quantized), Mixtral 8x7B, GPT-4o-mini, given no candidate .

Model cards: GPT-4 · GPT-4o

  • Measured on the paper's own benchmark: for artist prediction the best LLM reached 1.7% normalized 10-precision versus 11.9% for CognTKE; for festival prediction the best LLM reached 17.2% versus 41.4% for CountTRuCoLa. Popularity bias is evidenced by GPT-4o-mini naming Billie Eilish in the top 3 for 47.1% of queries and Llama 3.1 8B repeating one artist ~23 times per query. LLMs were not given the entity set, so part of the gap is the harder open-vocabulary setting rather than forecasting skill; [truncated]

Notes

Drafted from the paper by a model and filed unreviewed. Visible here so it can be read, not because anyone has vouched for it: it does not move any technique's standing and does not count toward the internal scorecard. Drafted confidence: medium. Falsifier as drafted: A zero-shot or retrieval-augmented LLM matching or exceeding the best TKG model's R-Precision and normalized 10-precision on the same 2025 test queries in both prediction directions, without popularity-biased or duplicated candidates.
