Abstract
In this paper we study the identification and verification of simple claims about statistical properties, e.g. claims about the population or the inflation rate of a coun- try. We show that this problem is similar to extracting numerical information from text and following recent work, instead of annotating data for each property of inter- est in order to learn supervised models, we develop a distantly supervised base- line approach using a knowledge base and raw text. In experiments on 16 statistical properties about countries from Freebase we show that our approach identifies sim- ple statistical claims about properties with 60% precision, while it is able to verify these claims without requiring any explicit supervision for either tasks. Furthermore, we evaluate our approach as a statistical property extractor and we show it achieves 0.11 mean absolute percentage error.
