Model Framework

  • DeepKE contains a unified framework for named entity recognition, relation extraction and attribute extraction, the three knowledge extraction functions.
  • Each task can be implemented in different scenarios. For example, we can achieve relation extraction in standard, low-resource (few-shot) and document-level 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.

Quick Start

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

Step1 Download the basic code

git clone https://github.com/zjunlp/DeepKE.git

Step2 Create a virtual environment using Anaconda and enter it.

We also provide dockerfile source code, which is located in the docker folder, to help users create their own mirrors.

conda create -n deepke python=3.8

conda activate deepke
  1. Install DeepKE with source code

    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

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

tar -xzvf data.tar.gz

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.

python predict.py

Introduction of Three Functions

1. Named Entity Recognition

  • Named entity recognition seeks to locate and classify named entities mentioned in unstructured text into pre-defined categories such as person names, organizations, locations, organizations, etc.

  • The data is stored in .txt files. Some instances as following:

    Sentence Person Location Organization

  • Read the detailed process in specific README

    • STANDARD (Fully Supervised)

      Step1 Enter DeepKE/example/ner/standard. Download the dataset.

      wget 120.27.214.45/Data/ner/standard/data.tar.gz
      
      tar -xzvf data.tar.gz

      Step2 Training

      The dataset and parameters can be customized in the data folder and conf folder respectively.

      python run.py

      Step3 Prediction

      python predict.py
    • FEW-SHOT

      Step1 Enter DeepKE/example/ner/few-shot. Download the dataset.

      wget 120.27.214.45/Data/ner/few_shot/data.tar.gz
      
      tar -xzvf data.tar.gz

      Step2 Training in the low-resouce setting

      The directory where the model is loaded and saved and the configuration parameters can be cusomized in the conf folder.

      python run.py +train=few_shot

      Users can modify load_path in conf/train/few_shot.yaml to use existing loaded model.

      Step3 Add - predict to conf/config.yaml, modify loda_path as the model path and write_path as the path where the predicted results are saved in conf/predict.yaml, and then run python predict.py

      python predict.py

2. Relation Extraction

  • Relationship extraction is the task of extracting semantic relations between entities from a unstructured text.

  • The data is stored in .csv files. Some instances as following:

    Sentence Relation Head Head_offset Tail Tail_offset
    《岳父也是爹》是王军执导的电视剧,由马恩然、范明主演。 导演 岳父也是爹 1 王军 8

Notebook Tutorial

This toolkit provides many Jupyter Notebook and Google Colab tutorials. Users can study DeepKE with them.


Tips

  1. Using nearest mirror, like THU in China, will speed up the installation of Anaconda.
  2. Using nearest mirror, like aliyun in China, will speed up pip install XXX.
  3. When encountering ModuleNotFoundError: No module named 'past',run pip install future .
  4. 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.
  5. 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).
  6. It's recommended to install DeepKE with source codes. Because user may meet some problems in Windows system with 'pip'.

To do

In next version, we plan to add multi-modality knowledge 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.
