# Model Framework

<h3 align="center">
    <img src="pics/architectures.png">
</h3>


- 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)**, **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. 

<br>

# Quick Start

*DeepKE* supports `pip install deepke`. <br>Take the fully supervised relation extraction for example.

**Step1** Download the basic code

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

**Step2** Create a virtual environment using `Anaconda` and enter it.<br>

 - **❗NOTE: We provide a [Dockerfile](https://github.com/zjunlp/DeepKE/tree/main/docker) with [tutorials](https://github.com/zjunlp/DeepKE/issues/145) please refer to the [Tips](#tips) to speed up installation**

```bash
conda create -n deepke python=3.8

conda activate deepke
```

1. Install *DeepKE* with source code (**Recommended**)

   ```bash
   python setup.py install
   
   python setup.py develop
   ```

2. Install *DeepKE* with `pip`

   ```bash
   pip install deepke
   ```
   

**Step3** Enter the task directory

```bash
cd DeepKE/example/re/standard
```

**Step4** Download the dataset, or follow the [annotation instructions](https://github.com/zjunlp/DeepKE/blob/main/README_TAG.md) to obtain data

```bash
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](https://docs.wandb.ai/quickstart)*.

```bash
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`.

```bash
python predict.py
```

 - **❗NOTE: if you encounter any errors, please refer to the [Tips](#tips) or submit a GitHub issue.**

## 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 (Users can label data based on the tools [Doccano](https://github.com/doccano/doccano), [MarkTool](https://github.com/FXLP/MarkTool), or they can use the [Weak Supervision](https://github.com/zjunlp/DeepKE/blob/main/example/ner/prepare-data) with DeepKE to obtain data automatically):

- Read the detailed process in specific README
  - **[STANDARD (Fully Supervised)](https://github.com/zjunlp/DeepKE/tree/main/example/ner/standard)**
    
    ***We [support LLM](https://github.com/zjunlp/DeepKE/tree/main/example/llm) and provide the off-the-shelf model, [DeepKE-cnSchema-NER](https://github.com/zjunlp/DeepKE/blob/main/README_CNSCHEMA_CN.md), which will extract entities in cnSchema without training.***

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

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

    **Step2** Training<br>

    The dataset and parameters can be customized in the `data` folder and `conf` folder respectively.
  
    ```bash
    python run.py
    ```

    **Step3** Prediction

    ```bash
    python predict.py
    ```
  
  - **[FEW-SHOT](https://github.com/zjunlp/DeepKE/tree/main/example/ner/few-shot)**

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

    ```bash
    wget 120.27.214.45/Data/ner/few_shot/data.tar.gz
    
    tar -xzvf data.tar.gz
    ```
  
    **Step2** Training in the low-resouce setting <br>
  
    The directory where the model is loaded and saved and the configuration parameters can be cusomized in the `conf` folder.
  
    ```bash
    python run.py +train=few_shot
    ```
    
    Users can modify `load_path` in `conf/train/few_shot.yaml` to use existing loaded model.<br>
    
    **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`
    
    ```bash
    python predict.py
    ```

  - **[MULTIMODAL](https://github.com/zjunlp/DeepKE/tree/main/example/ner/multimodal)**

    **Step1** Enter  `DeepKE/example/ner/multimodal`.  Download the dataset.

    ```bash
    wget 120.27.214.45/Data/ner/multimodal/data.tar.gz
    
    tar -xzvf data.tar.gz
    ```

    We use RCNN detected objects and visual grounding objects from original images as visual local information, where RCNN via [faster_rcnn](https://github.com/pytorch/vision/blob/main/torchvision/models/detection/faster_rcnn.py) and visual grounding via [onestage_grounding](https://github.com/zyang-ur/onestage_grounding).

    **Step2** Training in the multimodal setting <br>

    - The dataset and parameters can be customized in the `data` folder and `conf` folder respectively.
    - Start with the model trained last time: modify `load_path` in `conf/train.yaml`as the path where the model trained last time was saved. And the path saving logs generated in training can be customized by `log_dir`.

    ```bash
    python run.py
    ```

    **Step3** Prediction

    ```bash
    python predict.py
    ```

### 2. Relation Extraction

* Read the detailed process in specific README

  * [STANDARD(Fully Supervised)](./example/ee/standard/README.md)

    **Step1** Enter the `DeepKE/example/ee/standard` folder. Download the dataset.

    ```bash
    wget 120.27.214.45/Data/ee/DuEE.zip
    unzip DuEE.zip
    ```

    **Step 2** Training

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

    ```bash
    python run.py
    ```

    **Step 3** Prediction

    ```bash
    python predict.py
    ```

# Tips

1.```Using nearest mirror```, **[THU](https://mirrors.tuna.tsinghua.edu.cn/help/anaconda/) in China, will speed up the installation of *Anaconda*; [aliyun](http://mirrors.aliyun.com/pypi/simple/) 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](https://github.com/zjunlp/DeepKE/tree/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](https://github.com/zjunlp/DeepKE/blob/main/example/re/standard/README.md)).

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,see[issue](https://github.com/zjunlp/DeepKE/issues/117)

6.More related low-resource knowledge extraction  works can be found in [Knowledge Extraction in Low-Resource Scenarios: Survey and Perspective](https://arxiv.org/pdf/2202.08063.pdf).

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

# To do
In next version, we plan to release a LLM for KE. 

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.
