Continued Pre-training

Data

• Not all the data we used are publicly available. See data/README.md for details.
• python -m scripts.preprocess_continued_pretraining_data

Training

• Subword level: python -m scripts.continued_pretraining_subword <model_name_or_path>
  • Tested with xlm-roberta-base, facebook/xmod-base, ZurichNLP/swissbert
• Character level: python -m scripts.continued_pretraining_char <model_name_or_path>
  • Tested with google/canine-s, facebook/xmod-base, ZurichNLP/swissbert (the latter two correspond to the GLOBI approach described in Section 4.3 of the paper)

Evaluation

Data

• See data/README.md for instructions on how to download the data.

Fine-tuning and testing

• Part-of-speech tagging: python -m scripts.evaluate_pos <model_name_or_path>
• German dialect identification: python -m scripts.evaluate_gdi <model_name_or_path>
• Retrieval (no fine-tuning): python -m scripts.evaluate_retrieval <model_name_or_path>
