Requirements

To run the codes, you need to install the requirements:

pip install -r requirements.txt

Data Collection

The datasets that we used in our experiments are as follows:

• Twitter2017

  You can download the twitter2017 dataset via this link (https://drive.google.com/file/d/1ogfbn-XEYtk9GpUECq1-IwzINnhKGJqy/view?usp=sharing)

  For more information regarding the dataset, please refer to the UMT repository.

• MRE

  The MRE dataset comes from MEGA, many thanks.

  You can download the MRE dataset with detected visual objects using folloing command:

  cd MRE
  wget 120.27.214.45/Data/re/multimodal/data.tar.gz
  tar -xzvf data.tar.gz
  

• MKG

  • FB15K-237-IMG

    For more information regarding the dataset, please refer to the mmkb and kg-bert repositories.

  • WN18-IMG

    For more information regarding the dataset, please refer to the RSME repository.

How to run

• MKG Task

  • First run Image-text Incorporated Entity Modeling to train entity embedding.

      cd MKG
      bash scripts/pretrain_fb15k-237-image.sh
  

  • Then do Missing Entity Prediction.

      bash scripts/fb15k-237-image.sh
  

• MNER Task

  To run mner task, run this script.

  cd MNER
  bash run_mner.py
  

• MRE Task

  To run mre task, run this script.

  cd MRE
  bash run_mre.py
