The following statement has been inserted at the end of the second paragraph on the page 2:
“Studies of dependency distance distribution delivered informative results. Liu (2007) investigated six texts from a Chinese dependency treebank and found that the distributions of individual distances follow the right truncated Zeta distribution. The observed dependencies have a minimum tendency comparing to random treebanks. Based on an parallel English-Chinese Dependency treebank data, Jiang & Liu (2015) found the distribution of individual dependency distance follows similar patterns despite the differences of language features. After analyzing the distance distributions of 30 languages in HamleDT 2.0, Lu & Liu (2016) concluded that the distributions of languages all fit a mixed exponential and power-law distribution, although the patterns differ from languages. Although the late studies introduced more different language data, they did not set up random baselines as Liu (2007) did.”
