How Do We Use ChatGPT for Word-of-Mouth?

This study aims to show how to use ChatGPT to analyze word-of-mouth about cosmetics. First, ChatGPT is used to add titles to word-of-mouth about cosmetics and rate the reviews of @COSME on a 7-point scale in this study. The titles are extracted from the main text of the reviews, and the words used are moist, comfortable, like strawberry chocolate, thick texture, and full of freshness, which are emotionally impressive words. Second, ChatGPT rates the reviews and answers the reason for the rating. The rationale for the rating depends on the amount of text in the review, but most of them are explained in detail. Many mention whether or not they describe their impressions of the product and its effectiveness. Also, attention is paid to whether negative words, praise, and the intention to continue using the product can be read. Third, this study testifies whether or not ChatGPT can categorize the titles of word-of-mouth about cosmetics. As a result, ChatGPT cannot categorize alone. It was found that communicating with ChatGPT is needed to categorize the titles of word-of-mouth.
