Adapt Transformer-based language models to new text domains

Transformers Domain Adaptation

Documentation • Colab Guide

This toolkit improves the performance of HuggingFace transformer models on downstream NLP tasks, by domain-adapting models to the target domain of said NLP tasks (e.g. BERT -> LawBERT).

The overall Domain Adaptation framework can be broken down into three phases:

1. Data Selection

   Select a relevant subset of documents from the in-domain corpus that is likely to be beneficial for domain pre-training (see below)

2. Vocabulary Augmentation

   Extending the vocabulary of the transformer model with domain specific-terminology

3. Domain Pre-Training

   Continued pre-training of transformer model on the in-domain corpus to learn linguistic nuances of the target domain

After a model is domain-adapted, it can be fine-tuned on the downstream NLP task of choice, like any pre-trained transformer model.

Components

This toolkit provides two classes, DataSelector and VocabAugmentor, to simplify the Data Selection and Vocabulary Augmentation steps respectively.
