Welcome to the reboot of CounQER - a question answering system for COUNting Quantifiers and Entity-valued pRedicates. Demo available at https://counqer.mpi-inf.mpg.de/spo Details on demo is available at https://arxiv.org/pdf/2005.03529.pdf and the methodology at https://arxiv.org/pdf/2003.03155.pdf

Installation

1. Local machine

   To run the system in your local machine, start a simple HTTPS server and run it on port 9000. This is where the app will access data files. Type the command python -m SimpleHTTPServer 9000 on the command line to get it running. On another terminal start the flask app using the following lines of code.

cd ~/counqer_v1
python counqerv1.py

The app runs on port 5000 which can be changed by editing the port number in the file counqer.py.

2. Server setup

   You can also run this app on a web server. Install apache and configure the server. CounQER is already configured with the mod WSGI file. Make necessary changes in the server edits sections of the code to replace the paths with your server paths. The app is enables by the command apache2 a2ensite <your-server>
