In this paper, we applied automated methods to detect errors in Vietnammese Treebank based on the concept of equivalence classes proposed by Dickinson. On this basis, we propose an improved method of error detection by transforming syntax trees based on vertical markovization. Our experimental results on Vietnamese Treebank showed that the scope of error detection was extended more than 2 times and the precision was improved more than 18.07% in comparison with the base line methods. date: 2015-01 type: Conference or Workshop Item type: PeerReviewed identifier: Nguyen, Hong Quan and Nguyen, Phuong Thai and Dang, Thanh Quyen and Nguyen, Van Hiep (2015) Automatic detection of problematic rules in Vietnamese Treebank.
