Towards Collecting Commonsense Knowledge with Hint Questions

Accumulating commonsense knowledge (CK) has proven very useful for many natural language processing tasks. So far the most reliable way of acquisition is still relying on knowledge contributors to offer CK. Unfortunately, knowledge contributors often fail to think of much CK because this knowledge is usually taken for granted by people. In this paper, we explore the issue of reminding knowledge contributors by means of hint questions. Specifically, we investigate what kinds of CK are easily ignored, analyze its reason and suggest possible solution. We hope to sketch sources of the research problem and suggest possible ways forward.
