WNUT-2020-Task-2

Code for team datamafia's submission at WNUT 2020 Task 2: Identification of informative COVID-19 English Tweets.

Dataset

The dataset contains tweets labelled with INFORMATIVE or, NONINFORMATIVE in the context of Covid-19. Datasets can be found at https://github.com/VinAIResearch/COVID19Tweet

Requirements

Python 3.6 is needed to run the code. Install the dependencies using

$ pip install -r requirements.txt

How to run the experiments

All the experiments are stored inside ./experiments/ folder. Use --help to get the command line arguments expected by the code.

$ python exp3.py --help

execute RoBERTa baseline by running

$python exp3.py \
 --train_data ../data/raw/COVID19Tweet/train.tsv \
 --val_data ../data/raw/COVID19Tweet/valid.tsv \
 --transformer_model_name roberta-base \
 --model_save_path ../models/model_roberta/ \
 --max_text_len 100 \
 --dropout .2 \
 --epochs 10 \
 --lr .00002 \
 --train_batch_size 32 \
 --wandb_logging True \
 --seed 42
