HackerBERT

This is a simple demonstration to combine BERT with elasticsearch to improve search quality.

All setups are composed using Docker. In order to replicate the project, please just follow the steps below:

• Download HackerNews public data from Google BigQuery Public Dataset, and save it locally and set the path to dataset as environment variable:

export DATA_PATH=path_to_your_csv

• Download the BERT pre-trained embeddings. There are many pre-trained embeddings available, for instance, you could use wget:

wget https://storage.googleapis.com/bert_models/2018_10_18/cased_L-12_H-768_A-12.zip

And then unzip the folder, and set the absolute path of the folder as environment variable MODEL_PATH.

export MODEL_PATH=path_to_your_pretrained_model

• Create search index for elasticsearch, to make elasticsearch work, an index is needed to find search items, so simply do

export SEARCH_INDEX=any_search_index_name

• Move into the cloned repo, build and run dockers, there is the docker-compose file which composes of several dockers:

cd HackerBERT
docker-compose build
docker-compose up

• Create search indexes:

python main.py

• Play with it on http://127.0.0.1:1111
