+# BlueBert-Base, Uncased, PubMed
+
+## Model description
+
+A BERT model pre-trained on PubMed abstracts.
+
+## Intended uses & limitations
+
+#### How to use
+
+Please see https://github.com/ncbi-nlp/bluebert
+
+## Training data
+
+We provide [preprocessed PubMed texts](https://ftp.ncbi.nlm.nih.gov/pub/lu/Suppl/NCBI-BERT/pubmed_uncased_sentence_nltk.txt.tar.gz) that were used to pre-train the BlueBERT models. 
+The corpus contains ~4000M words extracted from the [PubMed ASCII code version](https://www.ncbi.nlm.nih.gov/research/bionlp/APIs/BioC-PubMed/). 
+
+Pre-trained model: https://huggingface.co/bert-large-uncased
+
+## Training procedure
+
+*  lowercasing the text
+*  removing speical chars `\x00`-`\x7F`
+*  tokenizing the text using the [NLTK Treebank tokenizer](https://www.nltk.org/_modules/nltk/tokenize/treebank.html)
+
+Below is a code snippet for more details.
+
+```python
+value = value.lower()
+value = re.sub(r'[\r\n]+', ' ', value)
+value = re.sub(r'[^\x00-\x7F]+', ' ', value)
+
+tokenized = TreebankWordTokenizer().tokenize(value)
+sentence = ' '.join(tokenized)
+sentence = re.sub(r"\s's\b", "'s", sentence)
+```
