Identifying Unclear Questions in Community Question Answering Websites

Understand

Thousands of complex natural language questions are submitted to community question answering websites on a daily basis, rendering them as one of the most important information sources these days.

• However, oftentimes submitted questions are unclear and cannot be answered without further clarification questions by expert community members.
• This study is the first to investigate the complex task of classifying a question as clear or unclear, i.e., if it requires further clarification.
• We construct a novel dataset and propose a classification approach that is based on the notion of similar questions.
