MUStARD: Multimodal Sarcasm Detection Dataset

This repository contains the dataset and code for our ACL 2019 paper:

Towards Multimodal Sarcasm Detection (An Obviously Perfect Paper)

We release the MUStARD dataset which is a multimodal video corpus for research in automated sarcasm discovery. The dataset is compiled from popular TV shows including Friends, The Golden Girls, The Big Bang Theory, and Sarcasmaholics Anonymous. MUStARD consists of audiovisual utterances annotated with sarcasm labels. Each utterance is accompanied by its context, which provides additional information on the scenario where the utterance occurs.

Example Instance

Example sarcastic utterance from the dataset along with its context and transcript.

Raw Videos

We provide a Google Drive folder with the raw video clips, including both the utterances and their respective context

Data Format

The annotations and transcripts of the audiovisual clips are available at data/sarcasm_data.json. Each instance in the JSON file is allotted one identifier (e.g. "1_60") which is a dictionary of the following items:

Key	Value
`utterance`	The text of the target utterance to classify.
`speaker`	Speaker of the target utterance.
`context`	List of utterances (in chronological order) preceding the target utterance.
`context_speakers`	Respective speakers of the context utterances.
`sarcasm`	Binary label for sarcasm tag.

Example format in JSON:

{
  "1_60": {
    "utterance": "It's just a privilege to watch your mind at work.",
    "speaker": "SHELDON",
    "context": [
      "I never would have identified the fingerprints of string theory in the aftermath of the Big Bang.",
      "My apologies. What's your plan?"
    ],
    "context_speakers": [
      "LEONARD",
      "SHELDON"
    ],
    "sarcasm": true
  }
}

Run the code

Setup an environment with Conda:

conda env create -f environment.yml
conda activate mustard
python -c "import nltk; nltk.download('punkt')"

Download Common Crawl pretrained GloVe word vectors of size 300d, 840B tokens somewhere.
Download the pre-extracted visual features to the data/ folder (so data/features/ contains the folders context_final/ and utterances_final/ with the features) or extract the visual features yourself.

Download the pre-extracted BERT features and place the two files directly under the folder data/ (so they are data/bert-output.jsonl and data/bert-output-context.jsonl), or [extract the BERT features in another environment with Python 2 and TensorFlow 1.11.0 following "Using BERT to extract fixed feature vectors (like ELMo)" from BERT's repo and running:

# Download BERT-base uncased in some dir:
wget https://storage.googleapis.com/bert_models/2018_10_18/uncased_L-12_H-768_A-12.zip
# Then put the location in this var:
BERT_BASE_DIR=...

python extract_features.py \
  --input_file=data/bert-input.txt \
  --output_file=data/bert-output.jsonl \
  --vocab_file=${BERT_BASE_DIR}/vocab.txt \
  --bert_config_file=${BERT_BASE_DIR}/bert_config.json \
  --init_checkpoint=${BERT_BASE_DIR}/bert_model.ckpt \
  --layers=-1,-2,-3,-4 \
  --max_seq_length=128 \
  --batch_size=8

Check the options in python train_svm.py -h to select a run configuration (or modify config.py) and then run it:
```
python train_svm.py  # add the flags you want
```
Evaluation: We evaluate using weighted F-score metric in a 5-fold cross validation scheme. The fold indices are available at data/split_incides.p . Refer to our baseline scripts for more details.
