===OVERVIEW===

The objective of NTCIR IMine is to explore and evaluate the technologies of satisfying different user intents behind a Web search query. The scope of IMine is highly related to the search result diversification in IR. In IMine-1, we received 73 runs from 10 teams in diverse countries such as Canada, China, France, Japan, Korea, US. Taking over the basic task designs in the previous IMine-1, IMine-2 will more focus on vertical intents behind a query. IMine-2 comprises of two subtasks: Query Understanding (QU) and Vertical Incorporating (VI) subtasks.

===TASKS====

IMine-2 at NTCIR-12 offers two subtasks as follows. Interested researchers and research groups can participate in either or both of the subtasks in any combination of languages.

– Query Understanding (QU) Subtask
(for English, Chinese, Japanese)

This subtask corresponds to the Subtopic Mining subtask (SM) in IMine, where participants are required to identify the subtopics of a given query. For example, given a query “harry potter,” the systems are expected to output its subtopics like “harry potter movie,” and “harry potter book.” The difference from the previous SM is that participants are also required to identify the vertical intents for each subtopic. That is, for a given query, the participants have to identify its subtopics and which vertical resources should be presented for the subtopic. The options of vertical resources could cover: news, image, Wikipedia, Q&A portal, video, application downloads, shopping etc.

– Vertical Incorporating (VI) Subtask
(for English, Chinese)

This subtask corresponds to the Document Ranking subtask (DR) in IMine, where participants are required to return the search results diversified with the subtopics. The difference from the previous DR is that the participants should decide whether the result list should contain vertical results. They should decide which position(s) in the organic result list should be presented with vertical results. Both the organic result list and the vertical result lists should be diversified with the intent mined from QU subtask.
Please note:

Task participants must submit a paper to the NTCIR-12 Conference (unrefereed) and at least one member of participated groups must attend the conference at NII, Tokyo in June 2016, to present your work.
