Abstract:

The goal of the LiveQA track is to automatically provide answers to questions posted by real people. Previous question answering tracks included factoid questions, list questions and complex questions3. Presented in 2015 for the first time the LiveQA track gave the participants an opportunity to answer questions posed by real people, as opposed to manually configured ones in the previous tasks. The questions for the task were harvested from Yahoo Answers1 a community question answering website. Each question was broadcasted to all registered systems. The participants had to supposed to provide an answer to every given question within a timeframe of 60 seconds. The answers were judged by human NIST assessors after the evaluation was over.
