Implementation of legal QA system based on SentenceKoBART

• How to train SentenceKoBART
• Based on Neural Search Engine Jina
• Provide Korean legal QA data(1,830 pairs)

# install git lfs , https://github.com/git-lfs/git-lfs/wiki/Installation
curl -s https://packagecloud.io/install/repositories/github/git-lfs/script.deb.sh | sudo bash
sudo apt install git-lfs
git clone https://github.com/haven-jeon/LegalQA.git
cd LegalQA
git lfs pull
pip install -r requirements.txt

python app.py -t index

GPU-based indexing available as an option

• pods/encoder.yml - on_gpu: true

To start the Jina server for REST API:

python app.py -t query_restful

Then use a client to query:

curl --request POST -d '{"top_k": 1, "mode": "search",  "data": ["상속 관련 문의"]}' -H 'Content-Type: application/json' 'http://0.0.0.0:1234/api/search'

Or use Jinabox with endpoint http://127.0.0.1:1234/api/search

python app.py -t query

• http://ec2-3-36-123-253.ap-northeast-2.compute.amazonaws.com:7874/

Model training, data crawling, and demo system were all supported by the AWS Hero program.
