Augmenting Wikipedia-Extraction with Results from the Web - scientific work about Wikipedia quality published in 2008, written by Feifei Wu, Raphael Hoffmann and Daniel S. Weld.
Overview
Not only is Wikipedia a comprehensive source of quality information, it has several kinds of internal structure (e.g., relational summaries known as infoboxes), which enable self-supervised information extraction. While previous efforts at extraction from Wikipedia achieve high precision and recall on well-populated classes of articles, they fail in a larger number of cases, largely because incomplete articles and infrequent use of infoboxes lead to insufficient training data. This paper explains and evaluates a method for improving recall by extracting from the broader Web. There are two key advances necessary to make Web supplementation effective: 1) a method to filter promising sentences from Web pages, and 2) a novel retraining technique to broaden extractor recall. Experiments show that, used in concert with shrinkage, their techniques increase recall by a factor of up to 8 while maintaining or increasing precision.
