Requirements

The model is implemented using PyTorch. The versions of packages used are shown below.

• numpy==1.18.0

• scikit-learn==0.22.1

• scipy==1.4.1

• torch==1.3.0

• tqdm==4.41.1

Baselines

The main experimental settings come from the project [Lifelong Relation Detection](https://github.com/hongwang600/ Lifelong_Relation_Detection).

We adapt some typical lifelong learning methods for continual relation learning, including EMR, AGEM and EWC. The code of these models can be found in the folder "./baseline/".

Datasets

We provide all the datasets and word embeddings used in our experiments.

Run the experiments

(0) To run the experiments, unpack the datasets and word embeddings first

unzip data.zip -d data/
unzip glove.zip -d glove/

(1) For FewRel

cp -r data/ fewrel/
cp -r glove/ fewrel/
cd fewrel
python run_multi_proto.py

(2) For SimpleQuestions

cp -r data/ simque/
cp -r glove/ simque/
cd simque
python run_multi_proto.py

(3) For TACRED

cp -r data/ tacred/
cp -r glove/ tacred/
cd tacred
python run_multi_proto.py

(4) For some special settings

All the config files can be found in "./fewrel/config/", "./tacred/config/", and "./simque/config/". By changing the config file name in the code "run_multi_proto.py", we can run experiments with different settings. In "./fewrel/config/", "./tacred/config/", and "./simque/config/", we also provide code to generate customized settings.
