• Each task can be implemented in different scenarios. For example, we can achieve relation extraction in standard, low-resource (few-shot), document-level and multimodal settings.
• Each application scenario comprises of three components: Data including Tokenizer, Preprocessor and Loader, Model including Module, Encoder and Forwarder, Core including Training, Evaluation and Prediction.

DeepKE supports pip install deepke.
Take the fully supervised relation extraction for example.

Step1 Download the basic code

git clone --depth 1 https://github.com/zjunlp/DeepKE.git

Step2 Create a virtual environment using Anaconda and enter it.

• ❗NOTE: We provide a Dockerfile with tutorials please refer to the Tips to speed up installation

conda create -n deepke python=3.8

conda activate deepke

1. Install DeepKE with source code (Recommended)

   python setup.py install
   
   python setup.py develop

2. Install DeepKE with pip

   pip install deepke

Step3 Enter the task directory

cd DeepKE/example/re/standard

Step4 Download the dataset, or follow the annotation instructions to obtain data

wget 120.27.214.45/Data/re/standard/data.tar.gz

tar -xzvf data.tar.gz

Many types of data formats are supported,and details are in each part.

Step5 Training (Parameters for training can be changed in the conf folder)

We support visual parameter tuning by using wandb.

python run.py

Step6 Prediction (Parameters for prediction can be changed in the conf folder)

Modify the path of the trained model in predict.yaml.The absolute path of the model needs to be used，such as xxx/checkpoints/2019-12-03_ 17-35-30/cnn_ epoch21.pth.

python predict.py

1.Using nearest mirror, THU in China, will speed up the installation of Anaconda; aliyun in China, will speed up pip install XXX.

2.When encountering ModuleNotFoundError: No module named 'past'，run pip install future .

3.It's slow to install the pretrained language models online. Recommend download pretrained models before use and save them in the pretrained folder. Read README.md in every task directory to check the specific requirement for saving pretrained models.

4.The old version of DeepKE is in the deepke-v1.0 branch. Users can change the branch to use the old version. The old version has been totally transfered to the standard relation extraction (example/re/standard).

5.It's recommended to install DeepKE with source codes. Because user may meet some problems in Windows system with 'pip',and the source code modification will not work,seeissue

6.More related low-resource knowledge extraction works can be found in Knowledge Extraction in Low-Resource Scenarios: Survey and Perspective.

7.Make sure the exact versions of requirements in requirements.txt.

In next version, we plan to add event extraction to the toolkit.

Meanwhile, we will offer long-term maintenance to fix bugs, solve issues and meet new requests. So if you have any problems, please put issues to us.
