Systems must aim to return important pieces of information and to minimise the amount of text the user has to read. These requirements are particularly important in mobile environments. 1CLICK-1 at NTCIR-9 only considered a Japanese task, but for this second round (1CLICK-2), we are expanding our scope to English. Moreover, while 1CLICK-1 considered only four query types (CELEBRITY, LOCAL, DEFINITION and QA), 1CLICK-2 will use a more fine-grained taxonomy comprising eight query types. Evaluation will be based on "information units" (iUnits), also often referred to as "nuggets". As in 1CLICK-1, we will use S-measure from Sakai/Kato/Song CIKM'11 http://research.microsoft.com/en-us/people/tesakai/cikmfp0040-sakai.pdf and will also consider developing new evaluation methods based on Pavlu et al. WSDM'12 http://dx.doi.org/10.1145/2124295.2124343 ### TASKS ### Japanese Main Task Given a Japanese query, return an X-character string that contain important information (X=500,140). This is basically the same as the 1CLICK-1 task. English Main Task Similar to the Japanese Main Task except that query and the output are in English. Query Classification Subtask (for Japanese and English) Given a query, classify it into one of the eight known query types. In addition to queries, the organisers will provide query suggestion data and baseline web search results to enhance repeatability and fairness, and to encourage newcomers to participate. ### IMPORTANT DATES ### Aug 31, 2012 test queries released Oct 31, 2012 run submissions due Nov 2012-Jan 2013 nugget match evaluation Feb 01, 2013 very early draft overview released Feb 28, 2013 evaluation results released Mar 01, 2013 draft participant papers due May 01, 2013 all camera ready papers due Jun 18-21, 2013 NTCIR-10 ### HOW TO PARTICIPATE ### Task registration page http://ntcir.nii.ac.jp/NTCIR10Regist/ We encourage new participants to have a look at the 1CLICK-1 overview paper to familiarise themselves with the task: http://research.nii.ac.jp/ntcir/workshop/OnlineProceedings9/NTCIR/01-NTCIR9-...
