NLP | How to add a domain-specific vocabulary (new tokens) to a subword tokenizer already trained like BERT WordPiece
Summary: In some cases, it may be crucial to enrich the vocabulary of an already trained natural language model with vocabulary from a specialized domain (medicine, law, etc.) in order to perform new tasks (classification, NER, summary, translation, etc.). While the Hugging Face library allows you to easily add new tokens to the vocabulary of an existing tokenizer like BERT WordPiece, those tokens must be whole words, not subwords. This article explains why and how to obtain these new tokens from a specialized corpus.

I trained 1 Portuguese Bidirectional Language Model (PBLM) with the MultiFit configuration with 1 NVIDIA GPU v100 on GCP.
WARNING: a Bidirectional LM model using the MultiFiT configuration is a good model to perform text classification but with only 46 millions of parameters, it is far from being a LM that can compete with GPT-2 or BERT in NLP tasks like text generation. This my next step ;-)
Note: The training times shown in the tables on this page are the sum of the creation time of Fastai Databunch (forward and backward) and the training duration of the bidirectional model over 10 periods. The download time of the Wikipedia corpus and its preparation time are not counted.
MultiFiT configuration (architecture 4 QRNN with 1550 hidden parameters by layer / tokenizer SentencePiece (15 000 tokens))
- notebook lm3-portuguese.ipynb (nbviewer of the notebook): code used to train a Portuguese Bidirectional LM on a 100 millions corpus extrated from Wikipedia by using the MultiFiT configuration.

| PBLM | accuracy | perplexity | training time |
|---|---|---|---|
| forward | 39.68% | 21.76 | 8h |
| backward | 43.67% | 22.16 | 8h |
- Applications:
- notebook lm3-portuguese-classifier-TCU-jurisprudencia.ipynb (nbviewer of the notebook): code used to fine-tune a Portuguese Bidirectional LM and a Text Classifier on "(reduzido) TCU jurisprudência" dataset.
- notebook lm3-portuguese-classifier-olist.ipynb (nbviewer of the notebook): code used to fine-tune a Portuguese Bidirectional LM and a Sentiment Classifier on "Brazilian E-Commerce Public Dataset by Olist" dataset.
[ WARNING ] The code of this notebook lm3-portuguese-classifier-olist.ipynb must be updated in order to use the SentencePiece model and vocab already trained for the Portuguese Language Model in the notebook lm3-portuguese.ipynb as it was done in the notebook lm3-portuguese-classifier-TCU-jurisprudencia.ipynb (see explanations at the top of this notebook).
Here's an example of using the classifier to predict the category of a TCU legal text:
I trained 3 French Bidirectional Language Models (FBLM) with 1 NVIDIA GPU v100 on GCP but the best is the one trained with the MultiFit configuration.
| French Bidirectional Language Models (FBLM) | accuracy | perplexity | training time | |
|---|---|---|---|---|
| MultiFiT with 4 QRNN + SentencePiece (15 000 tokens) | forward | 43.77% | 16.09 | 8h40 |
| backward | 49.29% | 16.58 | 8h10 | |
| ULMFiT with 3 QRNN + SentencePiece (15 000 tokens) | forward | 40.99% | 19.96 | 5h30 |
| backward | 47.19% | 19.47 | 5h30 | |
| ULMFiT with 3 AWD-LSTM + spaCy (60 000 tokens) | forward | 36.44% | 25.62 | 11h |
| backward | 42.65% | 27.09 | 11h |
