Multilingual Sentiment Analysis: An RNN-Based Framework for Limited Data
Table 5. Multiple comparison of means.
['group1', 'group2', 'meandiff', 'lower', 'upper', 'reject']
To be able to see the difference between baseline and RNN, we took each method’s results as a group (4 values: one for each language) and compared the means. When RNN is compared with lexicon-based baseline and majority baseline, the null hypothesis can be rejected meaning that each test is significant. In addition to these comparisons, we also calculated the effect sizes (using Cohen’s d) between the baselines and our method. The results are aligning with Tukey HSD results such that while our method versus baselines have very large effect sizes, lexicon-based baseline and majority baseline have negligible effect size.
