# ReviewBERT

BERT (post-)trained from review corpus to understand sentiment, options and various e-commence aspects.

`BERT-DK_rest` is trained from 1G (19 types) restaurants from Yelp.  

## Model Description

The original model is from `BERT-base-uncased` trained from Wikipedia+BookCorpus.  
Models are post-trained from [Amazon Dataset](http://jmcauley.ucsd.edu/data/amazon/) and [Yelp Dataset](https://www.yelp.com/dataset/challenge/).  


## Instructions
Loading the post-trained weights are as simple as, e.g., 

```python
import torch
from transformers import AutoModel, AutoTokenizer

tokenizer = AutoTokenizer.from_pretrained("activebus/BERT-DK_rest")
model = AutoModel.from_pretrained("activebus/BERT-DK_rest")

```
