by sileod - opened

Hi, thanks for building this benchmark! Here is a zero-shot submission for an open 150M extractor:

Model: tasksource/UltraBERT-150M-clairic-extraction (150M encoder, Apache-2.0)
Mode: zero-shot. It was never trained on typed-extraction train or test.

Headline ↑ Fields with a value ↑ Hallucination ↓ Miss ↓ Computed ↑ p_null AUROC ↑
0.616 0.548 0.141 0.297 0.014 0.815

Predictions: eval/typed-extraction-test-predictions.jsonl in the model repo, so you can re-score them.

How the predictions were made

  • One forward pass per field: the field's instructions paired with the document. The model tags the answer tokens (B/I/O), and long documents are read in overlapping 2,048-token windows.
  • No span means null, and p_null = 1 βˆ’ the best span's B probability.
  • Spans are mapped to types with plain code:
    • text as written;
    • number/duration: the first number in the span (k/m suffixes expanded);
    • date/time/datetime through dateutil, years defaulting to reference_date;
    • lists item by item.
  • No LLM, no prompt, no per-family rules.

Caveats

  • It's an extractor, so computed values (totals, counts, day spans) are mostly out of reach (0.014). That is where DROP, and part of the constructed families, lose points. Relative dates are only resolved when dateutil can parse them.
  • confidence is the raw span probability and is not calibrated (ECE 0.42). Ranking is fine (p_null AUROC 0.815).
  • Contamination check: our training data, the extraction config of tasksource-jev-typed-decisions, includes the public train splits of SQuAD 2.0, DROP and CUAD. Under a 120-character passage match, 23 of the 1,690 test documents (CUAD, DROP, Wikipedia) share text with it. Without those 23 cases, the headline is 0.616 (hallucination 0.142, miss 0.295), so they don't drive the score.

Latency: about 1.5 s per case on a shared A30 GPU, unoptimized and dominated by the long CUAD contracts (fields are run one by one). An int8 ONNX export runs in the browser: demo.

Thanks, added at #2 on the zero-shot table, behind ScaleDown Extract and ahead of Schematron V2 Small. First open-weight row, nice.

Re-scored the published predictions with unmodified score.py, numbers match. Computed came out 0.0135, shown as 0.013 on the card. Contamination note and caveats are under the table.

Hallucination 0.141 vs Schematron's 0.445 is a useful data point.
