This is an overview of the NTCIR-10 1CLICK-2 task (the second One Click Access task). Given a search query, 1CLICK aims to satisfy the user with a single textual output instead of a ranked list of URLs. Systems are expected to present important pieces of information first and to minimize the amount of text the user has to read. We designed English and Japanese 1CLICK tasks, in which 10 research teams (including two organizers’ teams) participated and submitted 59 runs for Main tasks and a Query Classification subtask. We describe the tasks, test collection, and evaluation methods, and then report official results for NTCIR-10 1CLICK-2.
