In this paper, we provide an overview of the NTCIR-12 IMine-2 task, which is a core task of NTCIR-12 and also a succeeding work of IMine@NTCIR-11, INTENT-2@NTCIR-10, and INTENT@NTCIR-9 tasks. IMine-2 comprises the Query Understanding subtask and the Vertical Incorporating subtask. 23 groups from diverse countries including China, France, India, Portugal, Ireland, and Japan registered to the task. Finally, IMine- 2 attracted 9 participating teams; we received 42 runs for the Query Understanding subtask and 15 runs for the Vertical Incorporating subtask. We describe the subtasks, data, evaluation methods, and report the official results for each subtask.
