pywsd-datasets

Unified Word Sense Disambiguation benchmark datasets, normalized to modern wn lexicon sense IDs (oewn:2024 for English, OMW for other languages).

Companion to pywsd ≥ 1.3.0.

What's shipped (v0.2)

English, test-only Raganato all-words benchmark:

Config Instances OEWN 2024 coverage
en-senseval2-aw 2,282 99.43 %
en-senseval3-aw 1,850 99.51 %
en-semeval2007-aw 455 99.78 %
en-semeval2013-aw 1,644 100.00 %
en-semeval2015-aw 1,022 99.32 %

English, training corpora (via UFSAC v2.1):

Config Split OEWN 2024 coverage
en-semcor train see coverage_report
en-wngt train see coverage_report
en-masc train see coverage_report
en-senseval2_ls train + test lexical-sample
en-senseval3_ls train + test lexical-sample
en-semeval2007_t17_ls test lexical-sample

Run python -m pywsd_datasets.scripts.coverage_report locally to get up-to-date OEWN resolution rates after rebuilding.

Install 

pip install pywsd-datasets

Use via HuggingFace datasets 

from datasets import load_dataset

# Raganato all-words evaluation set
ds = load_dataset("alvations/pywsd-datasets", "en-senseval2-aw")

# SemCor training data
ds = load_dataset("alvations/pywsd-datasets", "en-semcor")

ds["test"][0] if "test" in ds else ds["train"][0]
# {'instance_id': 'd000.s000.t000', 'dataset': 'senseval2_aw',
#  'split': 'test', 'lang': 'en',
#  'tokens': ['The', 'art', 'of', 'change-ringing', ...],
#  'target_idx': 1, 'target_lemma': 'art', 'target_pos': 'n',
#  'source_sense_id': 'art%1:09:00::',
#  'source_sense_system': 'pwn_sensekey_3.0',
#  'sense_ids_wordnet': ['oewn-05646832-n'],
#  'wordnet_lexicon': 'oewn:2024', ...}

Use via the loader package 

from pywsd_datasets.loaders.raganato import iter_instances as iter_raganato
from pywsd_datasets.loaders.ufsac import iter_instances as iter_ufsac

for inst in iter_raganato("senseval2"):
    print(inst.target_lemma, inst.sense_ids_wordnet)

for inst in iter_ufsac("semcor", "/path/to/ufsac-public-2.1"):
    print(inst.target_lemma, inst.sense_ids_wordnet)

Rebuild locally 

pip install pywsd-datasets[dev]

# Raganato only (always works, ~1 MB fetch from our GH release mirror)
python -m pywsd_datasets.scripts.build_all

# With UFSAC corpora — download ufsac-public-2.1 separately (see below)
python -m pywsd_datasets.scripts.build_all \
    --ufsac-root ~/.cache/pywsd-datasets/ufsac/ufsac-public-2.1

# Coverage report across every built parquet:
python -m pywsd_datasets.scripts.coverage_report

UFSAC download

UFSAC v2.1 is distributed as a single Google Drive tarball (ufsac-public-2.1.tar.xz, ~196 MB). Fetch with gdown:

pip install gdown
mkdir -p ~/.cache/pywsd-datasets/ufsac
gdown 'https://drive.google.com/uc?id=1kwBMIDBTf6heRno9bdLvF-DahSLHIZyV' \
    -O ~/.cache/pywsd-datasets/ufsac/ufsac-public-2.1.tar.xz
cd ~/.cache/pywsd-datasets/ufsac && tar -xf ufsac-public-2.1.tar.xz

Schema

Every row follows WSDInstance:

instance_id, dataset, split, task, lang,
tokens[], pos_tags[], lemmas[],
target_idx, target_lemma, target_pos,
source_sense_id, source_sense_system,
sense_ids_wordnet[], wordnet_lexicon,
doc_id, sent_id

sense_ids_wordnet is list-valued to handle multi-gold instances and any PWN-3.0 key that splits into multiple OEWN 2024 synsets.

Multilingual / XL-WSD / BabelNet — deferred

loaders/xl_wsd.py exists as a stub and raises NotImplementedError. mappers/babelnet_to_wn.py is similarly unused. Why:

  • XL-WSD uses BabelNet synset IDs as gold labels; resolving them to modern wn lexicon IDs requires the BabelNet → PWN 3.0 bridge file, which is distributed only with a BabelNet academic license.
  • XL-WSD itself is CC-BY-NC 4.0 — we don't redistribute the data.

Reviving this path requires (a) a BabelNet license, (b) loading bn_to_wn.txt via babelnet_to_wn.load_bn_to_pwn3_map(), (c) selecting per-language OMW lexicons via mappers.omw_lookup.lexicon_for(lang), then (d) chaining through pwn3_to_oewn.pwn3_sensekey_to_wn(key, lexicon=...). All four pieces are in place — wiring them is blocked on the BabelNet mapping file. See the module docstrings for details.

Roadmap

  • v0.2 (this release): Raganato all-words evaluation + UFSAC training corpora (SemCor, WNGT, MASC, Senseval lexical-sample).
  • v0.3 (planned): WiC (CC-BY-NC — loader-only), CoarseWSD-20.
  • Deferred: XL-WSD multilingual (needs BabelNet academic license).

Sense-ID mapping details

PWN 3.0 sense keys are resolved against OEWN 2024 via wn.compat.sensekey. The few percent of keys that fail to resolve are typically WN 3.0 synsets that OEWN split, merged, or removed — those rows ship with an empty sense_ids_wordnet list so the coverage report can flag them. Background:

  • Kaf (2023). Mapping Wordnets on the Fly with Permanent Sense Keys. arXiv:2303.01847.

Known issues

  • The upstream Raganato zip at http://lcl.uniroma1.it/wsdeval/ serves a mismatched TLS cert; our loader prefers the mirror on this repo's GitHub release assets and falls back to the original URL over HTTP.
  • UFSAC v2.1 is distributed as a Google Drive tarball; the loader assumes you have it unpacked locally. A future release may mirror it.
