This paper presents novel methods for modeling numerical common sense: the ability to infer whether a given number (e.g., three billion) is large, small, or nor- mal for a given context (e.g., number of people facing a water shortage). We first discuss the necessity of numerical com- mon sense in solving textual entailment problems. We explore two approaches for acquiring numerical common sense. Both approaches start with extracting numeri- cal expressions and their context from the Web. One approach estimates the distribu- tion of numbers co-occurring within a con- text and examines whether a given value is large, small, or normal, based on the distri- bution. Another approach utilizes textual patterns with which speakers explicitly ex- presses their judgment about the value of a numerica...
