Model Framework

Figure 1: The framework of DeepKE

• 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.

Quickstart

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

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
  本报北京9月4日讯记者杨涌报道：部分省区人民日报宣传发行工作座谈会9月3日在4日在京举行。	杨涌	北京	人民日报
  《红楼梦》是中央电视台和中国电视剧制作中心根据中国古典文学名著《红楼梦》摄制于1987年的一部古装连续剧，由王扶林导演，周汝昌、王蒙、周岭等多位红学家参与制作。	王扶林，周汝昌，王蒙，周岭	中国	中央电视台，中国电视剧制作中心
  秦始皇兵马俑位于陕西省西安市，1961年被国务院公布为第一批全国重点文物保护单位，是世界八大奇迹之一。	秦始皇	陕西省，西安市	国务院

• 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
  《九玄珠》是在纵横中文网连载的一部小说，作者是龙马。	连载网站	九玄珠	1	纵横中文网	7

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.
