Natural language processing (NLP) systems require commonsense knowledge to perform better inference and understanding on the contexts (e.g., dialogs and narratives) being processed. However, most NLP systems link facts from commonsense knowledge graphs based on simple heuristics, which fail to achieve promising performances and therefore leave current commonsense fact linking under-explored. Our goal is to conduct more rigorous study on the commonsense fact linking to enable stronger NLP systems. In this proposal, we first introduce three papers that are related to our research topic. The first paper provides background on commonsense knowledge graphs, while the second and third paper further illustrate how commonsense facts from knowledge graphs are applied to current NLP applications. Then we present our proposed commonsense fact linking benchmark facing current challenges in this technique, and finally point out potential directions for future work.
