Paired Comparison Sentiment Scores
Table 4: Pearson Correlation rp of the parity scores from the paired comparison with that of direct assignment and corpus-based methods.
['[EMPTY]', '[ITALIC] choice for  [ITALIC] F  [ITALIC] normal', '[ITALIC] choice for  [ITALIC] F  [ITALIC] logistic', '[ITALIC] choice for  [ITALIC] F  [ITALIC] uniform']
A natural measure for the closeness between lists of polarity scores is Pearson’s correlation coefficient rp, which has the advantage that it is invariant both under scale and translation of the variables. rp is highest for a linear relationship and smaller for other monotonous relationships. Whatever function is used, the correlation between the scores from direct assignment and paired comparison is very strong. This was to be expected, because both values stem from the same test persons.
