On peer-to-peer rental platforms, profile images may be useful for hosts and guests to infer individual characteristics and expectations. We try to fill a gap in the literature by inferring guests’ posting behavior through their profile image. Using Airbnb data and deep learning techniques, our empirical analysis reveals that guests who upload profile images—especially profile images displaying happy emotions—are more involved in posting long reviews. As theoretical implications, these results add knowledge to the application of the Five Factor Model of Personality, deep learning, image recognition, and emotion recognition in hospitality. As managerial implications, the prediction of posting behavior through the mining of visual information can be a relevant tool in the age of big data.5 page(s)application/pdfenIn CopyrightSocial SciencesHospitality, Leisure, Sport & TourismSocial Sciences - Other TopicsAirbnbReviewsProfile imageDeep learningPersonalityPHOTOSPERSONALITYTRUST1504 Commercial Services1505 Marketing1506 TourismSport, Leisure & TourismArticle - Refereed2022-01-13https://doi.org/10.1016/j.ijhm.2021.10296396Nicolau Gonzalbez, Juan [0000-0003-0048-2823]1873-4693
