Lichess Chess Positions: ML-Ready Deduplicated Evaluations
Dataset Description
A curated dataset of 316,072,343 unique chess positions with Stockfish evaluations, optimized for training neural networks. This is a deduplicated, ML-ready version of the Lichess evaluation database.
Why This Dataset?
While Lichess provides deduplicated evaluations in JSONL.zst format, and HuggingFace hosts the full (non-deduplicated) version, this dataset offers:

MELD Open (Normalized)
MELD is a multilingual and multi-domain dataset for Named Entity Recognition (NER) constructed from 60 existing datasets. It includes gold-standard annotations across 60 languages and 14 domains. This dataset is a subset of 43 datasets for which licenses permit the redistribution of data in a new format. See the MELD GitHub repository for more details.
Note: This version of MELD Open uses normalized labels. For original labels from each source dataset, use… See the full description on the dataset page: https://huggingface.co/datasets/kgnlp/meld-open-normalized.CartonPickNPlace2Target-normalizedgalaxea-r1-shelf-10ep-normalizedThis dataset was created using LeRobot.

Mathlib Normalized S-Expressions
Lean 4 proof states from Mathlib, paired with the tactic applied at each
step, in three representations extracted directly from the Lean kernel:
Source-faithful S-expressions of the goal and every hypothesis, as
Lean elaborated them.
Normalized S-expressions of the same state, with stable local-context
indices suitable for model input.

Netherlands Laws (Dutch, Normalized)
Hugging Face target: justicedao/netherlands-laws-nl-normalized.
This package is a normalized version of the Netherlands laws scrape output.
This is a capped Netherlands scrape, not the full Dutch corpus. The scrape used max_documents=100, parsed 151 law record(s), and discovered 626 unique official BWBR law document(s) before applying the cap. Documents failed: 0.
This refresh includes parser coverage improvements for older/French heading… See the full description on the dataset page: https://huggingface.co/datasets/justicedao/netherlands-laws-nl-normalized.databricks-dolly-15k-modernbert-kmeans-dim768-normalize-20250130test-community-normalizedThis dataset was created using LeRobot.
