- Evaluating the impact of instagram engagement metrics on corporate revenue growth: introducing the loyalty ratePublication . Sanches, Eva; Ramos, CeliaThis research explores the impact of social media metrics on revenue growth, specifically focusing on Instagram, a leading platform for businesses to engage consumers and promote offerings. It examines key metrics such as reach, impressions, interaction rate, and virality rate, which gauge user engagement with brand content. A novel metric, the loyalty rate, is introduced, combining interaction and virality rates to measure follower loyalty-those who not only engage but also share content, enhancing organic reach. The methodology involved comprehensive statistical analyses, including descriptive statistics, Pearson's correlations, and regression models, to investigate the relationship between social media metrics and monthly turnover. The findings reveal a moderate positive correlation between the loyalty rate and turnover, although the statistical significance was insufficient to establish a direct relationship. In contrast, metrics like follower count exhibited a stronger influence on financial performance, indicating that follower growth may be more critical for revenue generation. This study concludes that while engagement and loyalty matter, their effect on turnover is part of a broader digital strategy encompassing various factors beyond direct interactions. Practical recommendations are made for enhancing the loyalty rate and expanding research to include other platforms, like Facebook and LinkedIn, for a more comprehensive understanding of social media's impact on financial outcomes.
- Building company resilience: Determinants in the tourism industryPublication . Jesus, Carina; Serra Coelho, Luís Miguel; Ramos, CeliaWhat characteristics enable a company in the tourism industry to withstand and recover from disruptive events such as a global pandemic or a war? How can these firms enhance their resilience? This paper presents a systematic literature review of peer-reviewed publications on company resilience within the tourism industry to address these critical questions. Despite the current significance of these topics, existing research is fragmented and unconsolidated. Our findings reveal a range of perspectives and factors that influence company resilience, with clear evidence that human capital plays a pivotal role in the tourism industry’s ability to remain resilient. We also identify theoretical and practical implications, along with directions for future research.
- User-generated content and its impact on purchase intent for tourism products: a comparative analysis of millennials and centennials on tiktokPublication . Ramos, Eva Correia; Ramos, CeliaIn an increasingly technological society, online social networks are essential to support consumer purchasing decisions, primarily through User Generated Content (UGC). In this research, we look at the influence of UGC on purchase intent applied to the tourism product on the TikTok social network. In this sense, a survey was applied to TikTok users aged between 18 and 42 to compare their behaviour with that of the two generations: Millennials and Centennials. The results indicate a relationship of influence between credibility and the usefulness of information and between usefulness and social influence on the intention to buy tourism products and services. In addition, a comparison was made between the results of the sample of individuals belonging to the Millennial Generation and the sample of individuals belonging to the Centennial Generation, with the main discrepancy in the results being the relationship between the need for information and the usefulness of information. These insights pave the way for further research aimed at establishing more robust conclusions in this area.

- Large language models powered aspect-based sentiment analysis for enhanced customer insightsPublication . Água, Mariana; António, Nuno; Carrasco, Paulo; RASSAL, CARIMOIn the age of social networks, user-generated content has become vital for organizations in tourism and hospitality. Traditional sentiment analysis methods often struggle to process large volumes of data and capture implicit sentiments. This study examines the potential of Aspect-Based Sentiment Analysis (ABSA) using Large Language Models (LLMs) to enhance sentiment analysis. By employing GPT-4o via ChatGPT, we benchmark three approaches: a fuzzy logic-based method, manual human analysis, and a new ChatGPT-based analysis. We analyze a dataset of 500 all-inclusive hotel reviews, comparing these methods to assess ChatGPT's effectiveness in identifying nuanced language and handling subjectivity. The findings reveal a high similarity between ChatGPT and human analysis, showcasing ChatGPT's ability to interpret complex sentiments and automate sentiment classification tasks. This study highlights the potential of LLMs in transforming customer feedback analysis, providing deeper insights, and improving responsiveness in the hospitality industry. These results contribute to academia by presenting a framework for using LLMs in ABSA and guiding future applications and development.
- Banking reputation and its impact on stock markets: a big data analysis through online commentsPublication . Casado-Molina, Ana-María; Rojas-de-Gracia, María-Mercedes; Alarcón-Urbistondo, Pilar; Ramos, CeliaPurpose Given the substantial number of social conversations on the Internet, companies must remain vigilant about protecting their reputations and businesses. The purpose of this research is to measure the impact on share prices of reputational variables, measured through online comments, at the banking sector level as well as patterns of behavior between these variables and fluctuations in share rices. Design/methodology/approach Using big data and business intelligence techniques, bank reputation was analyzed through online social comments. The sample includes seven Spanish banks. To measure the impact of reputational variables on share prices, an Online Reputation Index was created. These variables were then correlated and filtered with the share price variation rate of each bank on a daily basis under two scenarios: using all share price data and also focusing on times of sharp fluctuations. Finally, multiple linear regression analysis was used to identify patterns in these relationships. Findings The findings reveal that negative comments focusing on attitude, emotions and governance experiences - particularly regarding ethical performance - are the only reputational variables with a clear impact on share price fluctuations in the banking sector. Strong correlations between reputation variables and share prices were observed only when online comments were extremely negative. These behaviors were more frequent during periods of significant price fluctuations. Originality/value This is the first study to analyze the impact of the reputation of the banking sector measured in the online environment on share price, taking into account its multidimensional construct.
- Multicriteria decision for selecting tourist destinations and increase its competitivenessPublication . Vanti, Adolfo; Solana-González, Pedro; Ramos, CeliaThe competitiveness of a tourist destination is related to its capacity to present products and services better than others, providing tourist experiences that meet the preferences of those who demand them. However, how tourists decide which destination to visit is a question that needs to be answered to support all destination stakeholders, and this is the aim of this research. This paper uses the Multi-Criteria Decision-Making approach to prioritise the types of tourism. The method applied is the Analytic Hierarchy Process, and the results showed the greater importance of the criteria of rest/simplicity and cultural difference. As for the tourist destinations, the most relevant in order of priority were Cruise tourism followed by Art/culture tourism, showing that these two types of tourism must be combined in a co-competition
- Strengthening cross-border ties: A participatory vision for EuroGuadiana TourismPublication . Panagopoulos, Thomas; Sedarati, Pooyan; Pinto Contreiras, JoaquimThis article delves into the intricacies of Eurocity of Guadiana (EuroGuadiana) cross-border initiative that seeks to bolster economic value through innovative tourism products. It delineates a comprehensive plan aimed at turning EuroGuadiana into a center of cultural and economic vibrancy within Andalusia/Algarve, thus overturning its current peripheral status, using a rich body of literature on regional development and tourism strategies. The key to this strategy is a meticulous tourism diagnosis, facilitated by a value chain tool that identifies existing resources and their potential for complementarity and cooperation, aligning strategic decisions with the factors that increase potential tourists’ perceptions. Participatory methods and transborder community development are key components of the strategy. The former encourages inclusivity and collaboration, integrating diverse stakeholder insights into the decision-making process, thereby fostering a strategy that is both grounded and adaptive to the evolving preferences of tourists. The latter leverages the region’s unique cross-border position to build cultural cohesion and economic synergy, promoting collaborative efforts in conservation and sustainable practices. Envisioned as a beacon of sustainable and inclusive development, EuroGuadiana aspires to emerge as a destination characterized by diversity, prosperity, and vibrancy. Furthermore, it aims to establish a collaborative platform that bridges cities within the region, fostering a network that is conducive to shared growth and innovation. With this multi-faceted approach, EuroGuadiana is being repositioned as a dynamic and harmonious hub of regional development.
- The Influence of firm characteristics and macroeconomic factors on financial performance: evidence from the portuguese hotel industryPublication . Matias, Fernanda; Rebelo, Sandra; Andraz, Georgette; Guerreiro, JoséThis study examines the determinants of the financial performance of the Portuguese hotel industry. Despite the economic relevance of the hotel industry and financial performance as an indicator of business survival, academic research on the factors that influence it in the context of this industry, particularly in Portugal, is not extensive. This study encompassed a sample of 738 hotel companies from 2016 to 2021, using data from the Orbis database. This research was based on the assumption that a company's size, liquidity, the tangibility of its assets, and debt level influence financial performance in the hotel industry, as well as the assumption that gross domestic product and consumer sentiment also affect the business success of hotel companies. By applying a panel data methodology, the findings indicate that all variables showed significant influence on financial performance, except liquidity. The analysis also reveals that smaller companies were more negatively affected by the demand decline induced by the COVID-19 pandemic. To improve the financial performance of the Portuguese hotel industry, the findings suggest that policymakers must work towards ensuring diversified sources of financing for the hotel business, such as investment subsidies, so that companies can minimize debt, especially during periods of slow economic growth. Additionally, companies must promote management strategies that enhance self-financing. Both measures could help companies increase their size, taking advantage of good business opportunities to explore economies of scale.
- How gastronomic image shapes tourism competitiveness: an approach with sentiment analysisPublication . Ramos, Celia; Pinto, KarinaThe competitiveness of tourist destinations is influenced by their relative attractiveness, which will play an essential role in their global success; gastronomy is one of the main motivations that lead tourists to visit a given destination. This research aims to investigate gastronomy's role in the destination's competitiveness and image through the analysis of online reputation, both in terms of ratings and sentiments provided by the experience, through the creation of an index of the online reputation of gastronomic image. Online restaurant reviews retrieved from TripAdvisor, from restaurants belonging to eight tourism destination regions, considered the competitive set to the Algarve, are analysed by applying sentiment analysis algorithms. With regard to the Algarve region, it was concluded that the Costa del Sol and the Tropical coast were the most competitive regions in terms of gastronomic image, where the inclusion of seafood products in meals was one of the strategic aspects used to increase the competitiveness of this region. These results can help restaurant managers and destination management organisations to better understand the different customer needs and how to increase their competitiveness.
