DAPFAM (A Domain‑Aware Patent Retrieval Dataset Aggregated at the Family Level)

Dataset DAPFAM

See the accompanying paper: Ayaou et al., 2025 — “DAPFAM: A Domain‑Aware Patent Retrieval Dataset Aggregated at the Family Level” (arXiv:2506.22141).

Summary

DAPFAM provides 1 247 balanced query patent families and 45 336 target families with forward/backward‑citation relevance labels (≈ 50 K pairs). Each relevant link is explicitly marked in‑domain or out‑of‑domain according to IPC 3‑char overlap, enabling rigorous cross‑domain evaluation.

• Full text (title · abstract · claims · description) plus rich metadata for every family.
• Multi‑jurisdictional, English‑only text (families may originate in US, JP, EP, CN, …).
• Parquet qrel file: qrels_all.parquet.
