NTCIR-11 Math-2

The NTCIR-11 Math-2 Task aims to develop an evaluation test collection for mathematical formulae search, in order to facilitate and encourage research in mathematical information retrieval and its related fields.

The NTCIR-10 Math Pilot Task was our initial attempt to develop a common workbench for mathematical formulae search. The task was completed successfully as an initial pilot task with 15 registrations and 6 submissions, showing a clear interest in the task. In the NTCIR-11 Math-2 Task, we will continue to pursue our initial goal to create an active and emerging community in Math IR.


What is Math Retrieval?

Search for a particular mathematical concept, often expressed using mathematical formulae.

Math Retrieval


Why is it difficult?

Mathematical formulae, in their machine readable forms, are expressed as complex trees.

Example of math tree structure

How can we find semantically similar math formulae? In order to answer the question, a search system should tackle at least (either of the) two challenges: (1) tree structure search, and (2) utilization of textual context information.


How to obtain sample topics?
