Quantitative Method for Evaluating Apparel Product Impressions Using Review Data

Research on extracting impression information from text has increased in recent years. Many studies have evaluated impressions using impression words (adjectives). However, the influence of degree adverbs that modify impression words on the strength and degree of impressions has not been sufficiently examined. Therefore, in this study, impression words and degree adverbs related to the four impression scales are collected to construct an impression dictionary for evaluating impressions of apparel products. Furthermore, rules for calculating impression scores are formulated using the vocabulary included in the impression dictionary. Finally, based on the constructed impression dictionary and calculation rules, impression scores are calculated using actual review texts of apparel products.
