Welcome to the NTCIR-12 IMine-2 Task. Our goal is to explore and evaluate the technologies of understanding user intents behind the query and satisfying different user intents. IMine-2 is a core task of NTCIR-12 and also a succeeding work of IMine@NTCIR-10, INTENT2@NTCIR-10, and INTENT@NTCIR-9. If you are new to the IMine/INTENT tasks, you may want to start by reading overview papers of IMine, INTENT2, and INTENT.
Really thank you for participating the NTCIR-12 IMine-2 Task! The overview paper of IMine-2 can be found at here.

IMine-2 is a second round of IMine task (IMine-1): please refer to the overview of IMine-1. The scope of IMine is highly related to the search result diversification in IR. Taking over the basic task designs in 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, which correspond to the Subtopic Mining subtask and the Document Ranking subtask in IMine-1, respectively.
In QU subtask, in addition to identifying the subtopics of a query, participants are required to predict which vertical resources (e.g., images, news, shopping, encyclopedia) should be presented for the subtopic. In VI subtask, in addition to diversifying the conventional organic results, participants are required to identify which position in the organic result lists should be presented as vertical results.
