Summary

This paper introduces three techniques for increasing recall of information extraction from Wikipedia's classes with a small number of articles (the long tail of sparse classes): shrinkage over a refined ontology, retraining using open information extractors and supplementing results by extracting from the general Web.

This paper improves a self-supervised information extractor first described in Wu and Weld CIKM 2007. The shrinkage technique uses a refined ontology, the output of Kylin Ontology Generator, an autonomous system presented in Wu and Weld WWW 2008). The retraining technique uses TextRunner, an open information extractor described in Banko et al IJCAI 2007.
