Subtree Mining for Relation Extraction from Wikipedia - scientific work related to Wikipedia quality published in 2007, written by Dat P.T. Nguyen, Yutaka Matsuo and Mitsuru Ishizuka.

Overview

In this study, authors address the problem of extracting relations between entities from Wikipedia's English articles. Authors proposed method first anchors the appearance of entities in Wikipedia's articles using neither Named Entity Recognizer (NER) nor coreference resolution tool. It then classifies the relationships between entity pairs using SVM with features extracted from the web structure and subtrees mined from the syntactic structure of text. Authors evaluate method on manually annotated data from actual Wikipedia articles.
