Question Analysis Restrictions
You can submit up to 99 runs, but we may evaluate the first three runs only. We will select the runs to evaluate and analyze according to the "priority" specified in the Run ID.

IR4QA Restrictions
We will accept up to 1,000 documents IDs, although we would evaluate the IR-effectiveness in terms of the effectiveness of the final QA results and we do not assess the relevance of the IR results themselves. IR results relevance may be able to assess later.

End-to-End and Combination QA Restrictions
You can submit up to 99 runs, but the first three run (PRIORITY = 01,02,03, ... ) should be evaluated.You can submit up to top 30 answers for each topic. However, due to resource constraints, we may not be able to evaluate all the answers in each topic.

See RunIDFormat for more details.
