This is a guide for developers.

Backend Setup

• Python >=3.6

• Install packages in requirements.txt

• Create Neo4j nodes ( Only the first time )

  change self.g in backend\lib\QASystemOnMedicalKG\build_buggraph.py ;answer_search.py ;decision_tree.py to your Neo4j port ,username and password.

  Uncomment these lines in build_buggraph.py

      # handler.create_graphnodes()
      # handler.create_graphrels()
  

  Then, run

  python build_buggraph.py
  

• Download Pre-trained BERT Model

• Start the BERT service

  bert-serving-start -model_dir \chinese_L-12_H-768_A-1
  

• Run

    python run.py --port=xxx --debug
  

  to check if any error occurred. "xxx" is a server port you can use, such as 5000. (Make sure this port is opened in your firewall rules)

Frontend Setup

• Change value of variable serverURL in frontend/src/api.js to

    http://your.ip.address:xxx
  

  In which "xxx" is the server port mentioned above.

• You need nodejs installed

• cd to the frontend directory, then run:

    npm install
  

• To check if you set the environment properly, try:

    npm start
  

  If everything goes fine, you should see:

    Compiled successfully!
    You can now view frontend in the browser.
        http://localhost:3000/
  

  Here, localhost means your IP address. For example, if your IP is 101.6.70.15, then open http://101.6.70.15:3000 in browser, you should see the page, that means everything is fine.
