# WordNet 3.0

## Overview
- dataset_id: wordnet
- license: WordNet 3.0 license (Princeton)
- homepage: https://wordnet.princeton.edu

## Dataset Structure Guide
This dataset publishes multiple Hub configs so researchers can choose the right view for their workflow.

### What Configs Mean
A config is a named dataset view. It selects which files are loaded and which split names are exposed.

### Available Configs
- aggregate: Default aggregate view across available variant paths.
  - splits: noun, verb, adj, adv
- data: Synset data files with glosses, words, pointers, and verb frames.
  - splits: noun, verb, adj, adv
  - file prefix: variants/data/
- index: Index files with lemma metadata, pointer symbol inventory, and synset offsets.
  - splits: noun, verb, adj, adv
  - file prefix: variants/index/
- exceptions: Exception files mapping inflected forms to base forms.
  - splits: noun, verb, adj, adv
  - file prefix: variants/exceptions/

### Quick Start (datasets library)
Use the config explicitly to avoid ambiguity and to get the expected split layout:

```python
from datasets import load_dataset

# Replace with your Hub repo id, e.g. '<namespace>/wordnet'
dataset = load_dataset('<namespace>/wordnet', 'aggregate')
print(dataset)
```

### Split Semantics
These splits may represent domain structure (for example part-of-speech groups) rather than train/validation/test partitions.
If you need ML evaluation splits, create an explicit derived split plan in downstream preprocessing.

## Summary
WordNet is published as lexical-resource views rather than benchmark train/validation/test tasks.

## Intended Use
- Lexical semantic analysis and symbolic NLP workflows.
- Knowledge graph and relation-structure exploration.
- Input resource for downstream task-specific data construction.

## Schema Notes
- The same part-of-speech split names (noun, verb, adj, adv) can appear across multiple configs.
- The aggregate config combines variant outputs while preserving split names.

## Evaluation Protocol
- For ML benchmarks, define explicit train/validation/test derivations from the lexical splits.
- Record any filtering or balancing logic to keep experiments reproducible.

## Limitations
- Not a native benchmark dataset with pre-defined evaluation partitions.
- Coverage and lexical conventions follow WordNet source files.

## Config Selection Guidance
- Use the data config for synset-level lexical structure.
- Use the index config for lemma and offset lookup behavior.
- Use the exceptions config for inflection-to-base mappings.
- Use aggregate when you want one entry point and can filter by variant in downstream code.

## Standardization
- split_aliases: {"dev": "validation", "val": "validation", "valid": "validation"}
- rename_map: {}
- selected_columns: []

## Exported Artifacts
- noun.parquet
- verb.parquet
- adj.parquet
- adv.parquet
- data
- WORDNET_FORMAT.md
- views/synsets.parquet
- views/words.parquet
- views/pointers.parquet
