WordNetNoun (Disambiguated Version)

This is a disambiguated version of the WordNet Noun hierarchy dataset, where entity names are formatted as name: definition to resolve polysemy issues.

Disambiguation

Original format (ambiguous):

child: "bank"
parent: "slope"

New format (disambiguated):

child: "bank: sloping land (especially the slope beside a body of water)"
parent: "slope: an elevated geological formation"

Problem Solved

In the original dataset, the word "bank" appears with multiple meanings:

• bank.n.01: "sloping land" → parent: slope
• bank.n.09: "a building in which banking transacted" → parent: depository
• bank.n.10: "flight maneuver" → parent: flight maneuver
• ... (8 different senses total)

This caused training signal conflicts where the same text "bank" needed to be embedded close to multiple different parents simultaneously.

Dataset Structure

Following the same structure as Hierarchy-Transformers/WordNetNoun:

• MixedHop-RandomNegatives-Pairs/: (child, parent, label) format for evaluation
• MixedHop-RandomNegatives-Triplets/: (child, parent, negative) format for training

Each contains train/val/test splits in parquet format.

Statistics

• Train: 750,915 pairs / 682,650 triplets
• Val: 364,925 pairs / 331,750 triplets
• Test: 364,936 pairs / 331,760 triplets
• Total entities: 74,401 (with definitions)

Source

• Original data: Zenodo 10511042
• Modification: Added WordNet definitions to entity names for disambiguation
• Code: Modified hierarchy_transformers.datasets.load module

Usage

from datasets import load_dataset

# Load disambiguated dataset
ds = load_dataset("Jinrui/WordNetNoun", "MixedHop-RandomNegatives-Pairs")

# Example
print(ds['train'][0])
# {
#   'child': 'boarhound: large hound used in hunting wild boars',
#   'parent': 'hound: any of several breeds of dog used for hunting...',
#   'label': 1
# }
