On-the-fly Table Generation

This repository contains resources developed within the following paper:

S. Zhang and K. Balog. On-the-fly Table Generation. In: Proceedings of SIGIR 2018, July 2018.

Test collection

The table corpus is WikiTables, which comprises 1.6M tables extracted from Wikipedia. We proproceeed it and make it public downloadable here.
