This study used sentiment analysis to analyze 232,496 Siri-related comments posted on the Weibo website. The results indicate that most of the posts have positive sentiments. Further analyses conducted using keyword extraction indicate that ‘come on to’ is among the most frequently used words in the posts that have highly positive or highly negative sentiments. This finding about ‘come on to’ is unusual and unexpected as there has been no discussion about this aspect of user experience in the literature. The results provide motivation for future research to explore and validate the significance of ‘come on to’ when users interact with chatbots. The results also indicate that developers should build chatbots that can handle challenging inputs that involve ‘come on to’ from users as this would elicit positive sentiments about their user experience.
