In addition to participating with innovative research, participants are cordially invited to participate with Question Answering systems. NLIWoD incorporates the 9th Question Answering over Linked Data (QALD) where users can display the capabilities of their systems using the provided online benchmarking platform GERBIL QA support by the H2020 project HOBBIT.

--------------------------------
## Important Dates
--------------------------------
- Training data available April 31st, 2018
- Integration of training data to the GERBIL QA platform by May 1st, 2018
- System submission due: September 1st, 2018
- System integration with GERBIL QA done: September 15th, 2018
- Publication of test data: October 8th, 2018
