Implementation of End-to-End Relation Extraction using LSTMs on Sequences and Tree Structures.

• Fedora Core 22
• clang++ 3.4
• boost 1.57
• yaml-cpp 0.5.1
• ICU4C 54.1

This code may work on other linux environments, but we have not tried them. For convenience, this package includes snapshot versions of clab/cnn (https://github.com/clab/cnn) and eigen (http://eigen.tuxfamily.org/). These follow the original license.

tar xzf cnn.tar.gz
tar xzf eigen.tar.gz
mkdir build
cd build
cmake .. -DEIGEN3_INCLUDE_DIR=eigen -DCMAKE_CXX_COMPILER=/usr/bin/clang++
make
cd ..

mkdir dict models

cd dict/
wget http://tti-coin.jp/data/wikipedia200.bin
cd ..

see data/README.md

These models are trained on the environments above (with Intel CPU). If you use other environments, please retrain the models to avoid the incompatibility problem.

cd models/
wget http://tti-coin.jp/data/ace2005-test.txt.gz
gunzip ace2005-test.txt.gz
cd ..

cd models/
wget http://tti-coin.jp/data/semeval-test.txt.gz
gunzip semeval-test.txt.gz
cd ..

Prediction results will be written as *.pred.ann in the test corpus directory.

YAML files for ACE2004 are not included. Please modify yaml/parameter-ace2005.yaml.

Scores may not be consistent with those in our paper due to the differences in the environments.
