This paper studies an abductive reasoning framework on natural language representations. We show how to incorporate Natural Logic (McCartney et al. 2009) into Interpretation as Abduction (Hobbs et al. 1993). The resulting framework avoids the difficulty of natural language-formal representation conversion, while handling important linguistic expressions such as negations and quantifiers. For proof-of-concept, we demonstrate that missing, implicit premises of arguments can be recovered by the proposed framework by a manual example walkthrough.
