Abstract

This is the final report of the OpenLiveQ-2 task at NTCIR-14. This task aimed to provide an open live test environment of Yahoo Japan Corporation’s community question-answering service (Yahoo! Chiebukuro) for question retrieval systems. The task was simply defined as follows: given a query and a set of questions with their answers, return a ranked list of questions. Submitted runs were evaluated both offline and online. In the online evaluation, we employed pairwise preference multileaving, a multileaving method that showed high efficiency over the other methods in a recent study. We describe the details of the task, data, and evaluation methods, and then report official results at NTCIR-14 OpenLiveQ-2. Furthermore, we demonstrate the effectiveness and efficiency of the proposed evaluation methodology.
