Colourful Language: Measuring Word–Colour Associations
Table 2: Percentage of terms in different majority classes.
['[BOLD] majority class size one', '[BOLD] majority class size two', '[BOLD] majority class size three', '[BOLD] majority class size four', '[BOLD] majority class size five', '[BOLD] majority class size ≥ two', '[BOLD] majority class size ≥ three']
Since the annotators were given eleven colour options to choose from, if we assume independence, then the chance that none of the five annotators agrees with each other (majority class size of one) is 1×10/11×9/11×8/11×7/11=0.344. Thus, if there was no correlation among any of the terms and colours, then 34.4% of the time none of the annotators would have agreed. However, this happens only 15.1% of the time. A large number of terms have a majority class size ≥ 2 (84.9%), and thus more than chance association with a colour. One can argue that terms with a majority class size ≥ 3 (32%) have strong colour associations.
