PTB PCFG Agreement 100M

Synthetic English pretraining corpora generated from a Penn Treebank-derived constituency PCFG.

Dataset description

This release contains three corpus variants with different subject-verb agreement cue reliability settings:

rel_0.5
rel_0.75
rel_1.0

Each variant contains:

en/tokens.txt
en/tokens.txt.metadata.json

The corpora use opaque token IDs rather than English word forms and were created for experiments on structural transfer from synthetic PCFG pretraining.
