We present a novel context pattern in- duction method for information extrac- tion, specifically named entity extraction. Using this method, we extended several classes of seed entity lists into much larger high-precision lists. Using token member- ship in these extended lists as additional features, we improved the accuracy of a conditional random field-based named en- tity tagger. In contrast, features derived from the seed lists decreased extractor ac- curacy.
