Stanford NLP Relation Extraction



Stanford NLP Relation Extraction

Lexical semantic relations

Many NLP applications require understanding relations between word senses: synonymy, antonymy, hyponymy, meronymy.
WordNet is a machine-readable database of relations between word senses, and an indispensable resource in many NLP tasks.

But WordNet is manually constructed, and has many gaps!

Relation extraction: 5 easy methods
1. Hand-built patterns
2. Bootstrapping methods
3. Supervised methods
4. Distant supervision
5. Unsupervised methods
