# MEDIC: A Multi-Task Learning Dataset for Disaster Image Classification

## Data

The MEDIC is the largest multi-task learning disaster-related dataset, an extended version of the crisis image benchmark dataset. It consists of data from several sources, including CrisisMMD, data from AIDR, and the Damage Multimodal Dataset (DMD). The dataset contains 71,198 images.

## Data Format and Directories

### Directories

- **data**: Main directory with the following subdirectories:
  - **aidr_disaster_types/**: Contains images collected using AIDR system for disaster types task.
  - **aidr_info/**: Contains images collected using AIDR system for informativeness task.
  - **ASONAM17_Damage_Image_Dataset/**: Damage Assessment Dataset.
  - **crisismmd/**: CrisisMMD dataset.
  - **multimodal-deep-learning-disaster-response-mouzannar/**: Damage Multimodal Dataset (DMD).
- **MEDIC_train.tsv, MEDIC_dev.tsv, MEDIC_test.tsv**: Training, development, and testing files with specific file formats.
- **LICENSE_CC_BY_NC_SA_4.0.txt**: License information.
- **terms-of-use.txt**: Terms and conditions.

### Format

- **image_id**: Corresponds to the tweet ID from Twitter or ID from the respective source.
- **event_name**: Name of the event or data source.
- **image_path**: Relative path of the image.
- **damage_severity**: Damage severity class label.
- **informative**: Informativeness class label.
- **humanitarian**: Humanitarian class label.
- **disaster_types**: Disaster types class label.
