D DA Department of Economics and Management University of Pisa A This paper focuses on the language used by con- sumers in a sample of TripAdvisor online reviews. We investigate, by means of automated text analy- sis, how the language infl uences the reviews’ useful- ness perception, i. e. the number of times the review has been marked as helpful by others. Our overall dataset consists of over million Tr- ipAdvisor hotel reviews from the top six European destinations (GDCI, ), Amsterdam, Barcelona, Istanbul, Paris, London, Rome and covering the – period. In this paper we focus on a sam- ple of reviews about Amsterdam. Results suggest that word count and some lin- guistic features of reviews have an infl uence on re- views’ usefulness perception. Implications for man- agers are provided.
