• lang: eg. eng, ara
• language.dev.csv: language specific csv file containing gold and ASR transcripts for all dialects
• language.dev.txt: language specific text file containing gold data
• language.dev.dialect-ASR.txt.jsonl.gz: Language and dialect specific TyDi-QA format datafile (gold question replaced with transcript)
• metadata.csv: metadata file (example ID-user ID mapping with additional info for each dialect and language)
• wav_lang: folder containing audio files
• asr_output_with_metadata_lang.csv: single language specific csv file containing all metadata, transcripts with word error rate for each example instance

Baseline-TydiQA

We train a tydiqa baseline model for the primary task evaluation. Instead of using the original training data, we use the discard_dev version (SDQA development questions are discarded from the training data).

Available model and training data for download:

• Trained checkpoint: Downolad to the folder trained_models/
• Original training/development dataset: Download to the folder tydiqa_data/
• discard_dev training dataset: Download to the folder tydiqa_data/
• language specific dev dataset replaced with asr output: Can be constructed using construct-tydiqa-datafile.ipynb
• language specific test dataset replaced with asr output: Can be constructed using construct-tydiqa-datafile.ipynb

Experimenting with a primary task baseline

Detailed steps to train a tydiqa primary task baseline model is here

prepare the training samples:

python3 baselines/tydiqa/baseline/prepare_tydi_data.py \
  --input_jsonl=tydiqa_data/tydiqa-v1.0-train-discard-dev.jsonl.gz \
  --output_tfrecord=tydiqa_data/train_tf/train_samples.tfrecord \
  --vocab_file=baselines/tydiqa/baseline/mbert_modified_vocab.txt \
  --record_count_file=tydiqa_data/train_tf/train_samples_record_count.txt \
  --include_unknowns=0.1 \
  --is_training=true

prepare dev samples from all language-dialect specific asr outputs

./experiments/test_prep.sh tydiqa_data/dev tydiqa_data/dev_tf

prepare test samples from all language-dialect specific asr outputs

./experiments/test_prep.sh tydiqa_data/test tydiqa_data/test_tf

train

python3 baselines/tydiqa/baseline/run_tydi.py \
  --bert_config_file=mbert_dir/bert_config.json \
  --vocab_file=baselines/tydiqa/baseline/mbert_modified_vocab.txt \
  --init_checkpoint=mbert_dir/bert_model.ckpt \
  --train_records_file=tydiqa_data/train_tf/train_samples.tfrecord \
  --record_count_file=tydiqa_data/train_tf/train_samples_record_count.txt \
  --do_train \
  --output_dir=trained_models/

Predict

Once the model is trained, we run inference on the dev/test set:

dev:

./experiments/test_predict.sh \
tydiqa_data/dev tydiqa_data/dev_predict tydiqa_data/dev_tf \
trained_models/model.ckpt discard_dev mbert_dir

test:

./experiments/test_predict.sh \
tydiqa_data/test tydiqa_data/test_predict tydiqa_data/test_tf \
trained_models/model.ckpt discard_dev mbert_dir

• to point the trained checkpoint at --init_checkpoint, write correct location inplace of trained_models/model.ckpt
• write downloaded mbert location inplace of mbert_dir

Evaluate

• see tydiqa_evaluation.ipynb
