Environment:

  • GPU: NVIDIA Tesla V100 SXM2
  • Python: python3.9

Installation

conda create -n biorex python=3.9
conda activate biorex
pip install -r requirements.txt

Train and evaluate BioREx

Step 1: Download the datasets for BioREx

You can download our converted datasets, and unzip it to

datasets/

If you want to convert the datasets by yourself, you can use the below script to convert original datasets into our input format.

bash scripts/build_biorex_datasets.sh

Step 2: Download the pre-trained model

Please download the model here

Then put them into

microsoft/

Step 3: Train and evaluate

bash scripts/run_biorex_exp.sh <CUDA_VISIBLE_DEVICES>

Please replace the above <CUDA_VISIBLE_DEVICES> with your GPUs' IDs. Eg: '0,1' for GPU devices 0 and 1. For example

bash scripts/run_biorex_exp.sh 0,1

BioREx pre-trained models

You can download the BioREx pre-trained models:

Predicting New Data:

If you only wish to use our tool for predicting new data without the need for training, please follow the steps outlined below:

Download the BioREx pre-trained model BioREx model file and place it in the "BioREx/" directory.

Open the "scripts/run_test_pred.sh" file and modify the values of the variables "in_pubtator_file" and "out_pubtator_file" to match your input PubTator file (with annotations) and the desired output PubTator file (where predicted relations will be stored).

Execute the following script to initiate the prediction process:

bash scripts/run_test_pred.sh <CUDA_VISIBLE_DEVICES>

Please replace the above <CUDA_VISIBLE_DEVICES> with your GPUs' IDs. Eg: '0,1' for GPU devices 0 and 1. For example

bash scripts/run_test_pred.sh 0,1
