Prediction Demo
There is a demonstration of prediction.
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
-
Install DeepKE with source code
python setup.py install python setup.py develop
-
Install DeepKE with
pippip 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.

.txtfiles. 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 -

2. Relation Extraction
-
Relationship extraction is the task of extracting semantic relations between entities from a unstructured text.

Tips
- Using nearest mirror, like THU in China, will speed up the installation of Anaconda.
- Using nearest mirror, like aliyun in China, will speed up
pip install XXX. - When encountering
ModuleNotFoundError: No module named 'past'，runpip install future. - It's slow to install the pretrained language models online. Recommend download pretrained models before use and save them in the
pretrainedfolder. ReadREADME.mdin every task directory to check the specific requirement for saving pretrained models. - 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).
- 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.
