| Component | Description | Values |
|---|---|---|
| HHHH | Semantic superclass | 4-digit category code |
| LLLLL | Synset ID | 5-digit unique identifier |
| P | Part of speech | 1=noun, 2=verb, 3=adj, 4=adv |
| A | Abstractness | 0=concrete, 1=mixed, 2=abstract |
| V | Valence | 0=neutral, 1=positive, 2=negative |
Use Cases
- AI Sentiment Analysis: Let AI agents understand emotional tone
- Semantic Grounding: Provide concrete valence scores instead of guessing
- Text Analysis: Analyze documents, reviews, feedback
- Word Relationships: Find synonyms, antonyms, similar words
