Exploiting Wikipedia as External Knowledge for Named Entity Recognition - scientific work related to Wikipedia quality published in 2007, written by Jun’ichi Kazama and Kentaro Torisawa.
Overview
Authors explore the use of Wikipedia as external knowledge to improve named entity recognition (NER). Authors method retrieves the corresponding Wikipedia entry for each candidate word sequence and extracts a category label from the first sentence of the entry, which can be thought of as a definition part. These category labels are used as features in a CRF-based NE tagger. Authors demonstrate using the CoNLL 2003 dataset that the Wikipedia category labels extracted by such a simple method actually improve the accuracy of NER.
