**(Apr. 11) Topics for Task 2 are now available.**- The corpus for both tasks is available online.
- Formulas provided in LaTeX, Presentation MathML, and Content MathML
- Manual and automatic runs will be collected.

- Top-k formulas from participants + additional manual runs by organizers will be pooled.
*Assessors can use formula hits + pools from Task 1 to identify similar formulas.* - Most topics will be assessed once, some doubly-assessed to check agreement. Assessors include volunteers from teams along with hired assessors.
**(Mar 23) Update:**we will be using nDCG' (i.e., nDCG after ignoring hits missing from the evaluation pool) to promote fair comparison with systems that do not participate in the task.
