Knowledge graphs (KGs) such as Freebase (Bollacker et al. 2008), DBpedia (Auer et al. 2007), and YAGO (Mahdisoltani, Biega, and Suchanek 2014) play a critical role in various NLP tasks, including question answering (Hao et al. 2017), information retrieval (Xiong and Callan 2015), and personalized recommendation (Zhang et al. 2016).
