Intent and Search Task Mining: Invitation to the NTCIR-11 IMine Task

Abstract

This paper introduces the NTCIR-11 IMine task, whose aim is to explore and evaluate technologies of mining and satisfying different user intents behind a Web search query. The NTCIR- 11 IMine task comprises three subtasks: (1) Subtopic Mining, (2) Document Ranking, and (3) Search Task Mining. We briefly introduce these subtasks and how to participate in them. Japanese researchers in information retrieval, natural language processing, interactive information access, or machine learning are highly welcome to participate in the IMine task to accelerate their research.
