Principal Component Analysis was performed to identify semantic structure of Kansei Words. The analyses were based on the average of evaluation results obtained from subjects. Results of PC Loadings were analyzed to see differences of determinants by size of data population. It is evident from the study that population size does not affect determinants of affective web interface design. The study makes decent contribution in determining appropriate population size in designing research instruments for future studies involving website affective evaluations.
