Cross-relation Cross-bag Attention for Distantly-supervised Relation Extraction

Source code and data for [Cross-relation Cross-bag Attention for Distantly-supervised Relation Extraction] (https://arxiv.org/abs/1812.10604)

--------------------------------------------------------------------------------

Training relation extractor with Cross-relation Cross-bag Attention:

  • employ the sentence-level selective attention to reduce the effect of noisy or mismatched sentences, while the correlation among relations were captured to improve the quality of attention weights.
  • try to pay more attention to entity-pairs with a higher quality.

Environment

Python 2.7 Pytorch 0.3.0

Data

We include NYT dataset in the Data folder.

Train

A demo is provided and can be execurated by:

python train.py

Test

After training, the model will be saved in /model

python test.py
