THUIR at NTCIR-12 IMine Task

In this paper, we describe our approaches in the NTCIR12 IMine task, including Chinese Query Understanding and Chinese Vertical Incorporating. In Query Understanding subtask, we propose different strategies to mine subtopic candidates from a wide range of resources and present a twostep method to predict the vertical intent for each subtopic. In Vertical Incorporating subtask, we adopt a probabilistic algorithm to rerank the result lists of Web documents and incorporate virtual verticals into the result lists based on the intent of subtopic behind the query.
