- Exploring consumer experiences in Wine Tourism through sentiment analysis: An assessment of Tripadvisor reviews about Wineries in France, Portugal, and ItalyPublication . Siegl, Laura; Baptista, Ema; Ruvo, Daniele; Ramos, CeliaThis study examines TripAdvisor reviews from three wineries in Europe to analyze customer perceptions and preferences in wine tourism. The investigation aims to understand the impact of online reviews on winery reputations and customer satisfaction in the context of wine tourism experiences. The study utilizes an advanced data analytics tool, namely Power BI, to analyze the development and demographics of the reviews and Orange Data Mining to conduct sentiment analysis and text mining. By examining reviews from wineries in France, Portugal, and Italy, this work identifies key themes, sentiments, and preferences expressed by customers, providing actionable insights for wineries to enhance visitor experiences and strategic decision-making in the wine tourism industry using an artificial intelligence approach.
- Understanding air passengers' motivations and constraints for supporting sustainable air travelPublication . Siegl, Laura; Almeida, Cláudia Margarida Brito Ribeiro deThis work addresses the problem of achieving sustainable development in the aviation sector within the context of tourism. It combines a systematic literature review and a quantitative empirical study to provide a comprehensive analysis of the field. The review follows PRISMA 2020 guidelines and includes 48 peer-reviewed publications from 2011 to 2024, selected from Scopus, Web of Science, B-On, and Google Scholar. Eligible sources met strict quality, relevance, and methodological criteria and were assessed using a CASP-based checklist. The results allow for a characterisation of current research trends, highlighting a post-2020 shift toward optimisation models, value-based communication, and climate equity, alongside earlier work focused on behavioural factors. Despite growing academic attention, a gap remains between scholarly insight and practical application. Building on these findings, the empirical investigation analysed 432 air passenger survey responses using descriptive statistics, inferential analysis, Structural Equation Modelling (SEM), and cluster analysis. The study examined motivations and constraints influencing support for and willingness to pay for sustainable flights. Environmental concerns such as carbon reduction and intergenerational responsibility emerged as strong motivators, while cost, lack of awareness, and booking complexity posed significant barriers. SEM results show that sustainability awareness mediates the relationship between motivation, constraint, travel regularity, and willingness to pay. Frequent flyers, although more aware, showed lower spending inclination, suggesting cognitive dissonance. Demographic factors such as age and income had some influence, gender differences were not significant. Evidence from the study shows that the problems surrounding sustainable aviation require both behavioural and systemic solutions. The insights gained led to the presentation of interdisciplinary recommendations, emphasising targeted policy strategies, better communication, and non-price incentives to align consumer behaviour with climate goals.
