6.2　Method

The corpus used in this study is the same move-annotated corpus constructed in Study 2(see Table 17 for the move model).As mentioned above,the corpus is designed purposefully to enable the investigation of factors underlying individual variation.Based on the quantitative study of each sub-corpus,boxplots and line charts were drawn to visualize the individual differences in each local community.The significance of differences associated with research traditions,changes over time,and former community influences were calculated separately using Kruskal-Wallis tests,Multivariate Analysis of Variance(MANOVA)and a discriminant test.
