We conducted questionnaire surveys and experiments on odor quality evaluation in order to determine the criteria for selecting expressions that properly represent various kinds of odors and allow evaluation with high reproducibility. First, we chose 303 words and conducted questionnaire surveys on their suitability for the evaluation. Then, we performed experiments on odor quality evaluation with 80 odor samples. The result suggested that the difficulty in understanding odor quality representation, general frequency of use, variation in evaluation score, and correlation among evaluation expressions should be considered.
