Online persuasion of review emotional intensity: A text mining analysis of restaurant reviews

Consumer-generated restaurant reviews are important sources in consumers’ purchase decisions. The purpose of this study is to explore the impact of emotional intensity on perceived review usefulness as well as the moderating effects of review length and reviewer expertise. Data from 600,686 reviews of 300 popular restaurants in the US were obtained from Yelp. Using a text mining approach and econometric analysis, empirical results show that (1) positive emotional intensity has a negative impact on perceived review usefulness, whereas negative emotional intensity has a positive impact on perceived review usefulness; (2) among the two most prevalent discrete negative emotions in online reviews (i.e., anger and anxiety), reviews expressing anger are more useful than those expressing anxiety; and (3) review length and reviewer expertise can moderate the effect of emotional intensity on perceived review usefulness.     

Unveiling the cloak of deviance: Linguistic cues for psychological processes in fake online reviews

Although fake online reviews have been gaining more attention from both academics and practitioners, little effort has been made to explore the linguistic characteristics of the psychological processes related to fake reviews. This research proposes four linguistic cues (i.e., affective, cognitive, social, and perceptual) related to a reviewer’s psychological processes and explores their relationships with fake reviews while examining the influence of time distance and reviewer location on these reviews. The results of logistic regression analysis of 43,496 reviews from Yelp.com suggest that affective, social, and perceptual cues are significantly related to fake reviews with the presence of the significant effects of time distance and reviewer location. Further, the results of post-hoc analysis confirm that the effect of photos on fake reviews is limited. This study contributes to the body of knowledge on online reviews and interpersonal deception theory, providing valuable implications for practitioners in the hospitality and tourism industry.     

What moderates the influence of extremely negative ratings? The role of review and reviewer characteristics

Online customer reviews are increasingly used by travelers to inform their purchase decisions. However, the vast amount of reviews available nowadays may increase travellers’ effort in information processing. In order to facilitate traveller’s decisions, social commerce organizations must help travellers rapidly identify the most helpful reviews to reduce their cognitive effort. Academic literature has often documented that negative reviews are judged as helpful by consumers. However, extremely negative reviews are not always perceived as such. This study is the first that unveils what factors moderate the influence of extremely negative reviews on review helpfulness. The study has adopted a sample of 7455 online customer reviews of hotels to test hypotheses. Findings show that reviews with extremely negative ratings are more likely to be helpful when the review is long and easy to read and when the reviewer is an expert or discloses his identity (i.e. geographical origin).     

The effects of consumer experience and disconfirmation on the timing of online review: Field evidence from the restaurant business

This study investigated the effects of consumer experience and disconfirmation on the timing of online reviews. Based on a unique dataset of restaurant reservations and online reviews, the empirical results indicate that (1) there is a reverse U-shaped relationship between consumer experience and online review posting timing, i.e., consumers who have strongly dissatisfying or satisfying experiences tend to post online reviews earlier than consumers who have moderate experience; (2) the disconfirmation between a customer’s experience and the average rating of prior reviews has a negative effect on his or her online review posting speed; and (3) the effect of disconfirmation on review posting speed is substantial for consumers who have strongly dissatisfying or satisfying experiences, while it is weaker for consumers who have moderate experience.     

The Influence of Reviewer Demographic Information Provision on Trust and Purchase Intent for Users of Online Websites

E-commerce websites are increasingly interested in how to effectively utilize online reviews to positively influence consumer decisions. One potential mechanism is providing socio-demographic information about reviewers along with the reviews. This study investigates how consumer decision outcome variables (e.g., perceived usefulness, trust and purchase intent) change when reviewers’ age and gender are provided and when a consumer’s and reviewer’s age/gender are same or similar. The hotel industry was utilized as the context. The results from the experiment showed that, regardless of the compatibility of the provided demographic information (reviewers’ vs. consumers’), providing reviewers’ age and gender positively impacted consumers’ perceived online trust, and about half of the participants processed and remembered the demographic information. It was additionally noted that people who could remember reviewers’ demographic information had not only more trust in the reviewer, the specific company’s website, and the specific hotel itself, but also higher intention to recommend and book the hotel.     

Understanding the dynamics of review posting and the management intervention effects on those dynamics

The purposes of the paper are (1) to examine the dynamic properties of online reviews, focusing on whether previous review trends contribute to herding or reactant behavior in subsequent review rating generation (dynamic flow), and (2) to explore the business value of management responses in the dynamic flow of online reviews based on Social Impact Theory and Rational Action Theory as the foundation. To this end, we analyze a series of regression and logistic models with quasi-experimental cases from a large online review dataset, collected from a leading online travel website in China. We find that both types of previous trends of reviews, positive and negative, contribute to reactant behavior in subsequent review rating generation. When the review trends are considered with management responses, we find that management responses have a positive impact on subsequent review ratings in the negative review trend, but not in the positive review trend.     

Responding to negative online reviews: The effects of hotel responses on customer inferences of trust and concern

Our research examines the perceptions and evaluations of prospective customers toward an online negative review and any accompanying hotel response. The study explores two main issues: whether the presence (versus absence) of an organizational response to negative customer reviews affects the inferences potential consumers draw about the target business, and which aspects of responses affect their impressions. We test the effects of four variables associated with a response: source of response, voice of responder, speed of response, and action frame on two outcomes variables (i.e., customer concern and trust inferences). The provision of an online response (versus no response) enhanced inferences that potential consumers draw regarding the business's trustworthiness and the extent to which it cares about its customers. Using a human voice and a timely response yielded favorable customer inferences. Inferences did not vary with response source or action frame. Implications are drawn for effective management of negative online reviews.     

Exploring the comparative importance of online hotel reviews’ heuristic attributes in review helpfulness: a conjoint analysis approach

Online travel reviews have become increasingly important as a result of the intangible and heterogeneous characteristics of the tourism industry as well as the recent diffusion of social media. This exploratory case study intends to examine the comparative importance of the six heuristic attributes (reviewer location, reviewer level, reviewer helpful vote, review rating, review length, and review photo) with respect to review helpfulness in the online hotel review context. Moreover, the salience of the individual levels within each review attribute and the importance of the attributes in positive and negative review-rating groups are compared. In total, 1,158 reviews of a hotel on TripAdvisor were collected and analyzed through conjoint analyses. This study found that the review rating and reviewer helpful vote attributes are the two most important factors. Finally, three major propositions are suggested based on findings of the study, and several theoretical and managerial implications are discussed.     

Infusing new insights: How do review novelty and inconsistency shape the usefulness of online travel reviews?

Review usefulness represents a vital indicator for evaluating the quality of online reviews in the tourism industry, and various heuristic cues have been recognized as determinants of this indicator. This study constructs a comprehensive conceptual framework based on the heuristic-systematic model to observe how two systematic cues, namely, review novelty and inconsistency, shape the perceived usefulness of reviews. Through an empirical analysis based on 1,744,693 reviews of 62,543 restaurants in the United States, we unveil a positive effect of review novelty on review usefulness but a negative effect of review inconsistency. We also underscore the moderating effects of several heuristic cues in the model, including review valence, reviewer expertise, and restaurant popularity. These results indicate that systematic and heuristic cues simultaneously and interactively determine review usefulness. The findings present theoretical implications to the literature and practical implications to hospitality professionals and designers/managers of review platforms.     

Which reviewers are honest and caring? The effect of constructive and prosocial information on the perceived credibility of online reviews

Consumers often infer review credibility based on the content of online reviews. This study explores the influences of three positive review types on consumers’ perceptions of posters’ honesty and caring and subsequently review credibility. An experiment was conducted and the participants included 931 online travel community users. The results found that compared with positive reviews that contain only complimentary information, reviews that also contain constructive or prosocial information improve subjects’ perception of posters’ honesty and caring, respectively, and that this influence is particularly significant for participants with low propensity to trust. Second, compared with hotels with high reputation, consumers have significantly reduced perceptions of reviewers’ honesty if the reviewers provide only complimentary information in positive reviews for hotels with low brand reputation rather than both complimentary and constructive information. Finally, the higher the subjects’ perception of the reviewers’ honesty and caring is, the higher the consumers’ perception of review credibility.     

Roles of emotional expressions in review consumption and generation processes

This research examines how the relationship between review ratings and perceived review helpfulness varies when emotional expressions reflected in the textual content of customer reviews are considered. Moreover, we investigate how mobile devices affect emotional expressions in reviews with the same review ratings. We recruited participants from Amazon MTurk and collected online customer review data from TripAdvisor.com. Our analyses reveal that negativity bias exists in emotional expressions and applies to both the review generation and consumption processes. For positively rated reviews, negative emotional expressions are used more often and are perceived to be more helpful. For negatively rated reviews, positive emotional expressions are less used and perceived as less helpful. Our results also show that the reviews posted via mobile devices tend to be more emotional, for reviews with the same ratings. By showing the direct and indirect impacts of mobile devices, this research provides valuable theoretical and managerial information.

The impact of language style on consumers′ reactions to online reviews

The current research examines the novel impact of an online review's language style (figurative vs. literal) on consumers' attitudes towards a hotel and their reservation intention. Previous marketing research advocated for the use of figurative language to advertise hedonic consumptions. Yet, we found that, in the context of online hotel reviews, figurative language doesn't offer significant advantages in terms of persuasive power. Specifically, our findings indicate that, when a review is posted by a reviewer with low expertise level, consumers actually exhibit lower levels of attitude and reservation intention if the review is written in figurative (vs. literal) language. When the reviewer possesses high expertise level, the language style effect was attenuated. Finally, serial mediation tests show that the causal link between language typicality → perceived reviewer expertise explains the language style effect on consumers' pre-purchase evaluations.     

Booking now or later: Do online peer reviews matter?

Consumers always face a tradeoff between making a purchase decision now and continuing information searching with delayed purchase decision. This study extends extant literature by empirically investigating the effects of online peer reviews on consumers’ timing of booking a restaurant using a merged data set of online peer reviews and consumer reservation records. The results show that the rating valence, rating variation, and review content richness of online peer reviews positively motivate potential consumers to book a restaurant earlier, while the time interval between successive reviews hinders consumers’ booking decision. It is also found that the effects of rating valence on timing of restaurant booking depend on the different levels of rating variation and review content richness. The findings of this study help practitioners better understand consumers’ purchase decision process and improve marketing strategies.     

Mechanisms of consumers' trust development in reviewers' supplementary reviews: A reviewer-reader similarity perspective

The literature on online reviews tends to focus on initial consumer postings and reviews, but supplementary online reviews posted by the same reviewer remain an unexplored area in marketing in general and hospitality in particular. To address this gap in the research, this study offers a research model that examines the effects of reviewers' attributes on consumer trust and positive behavioral outcomes, using hotel attributes performance as a moderator. Using responses from 414 hospitality consumers in China, our findings reveal that reviewers whose supplementary reviews use similar identities to those of their initial review, review similar firms, and use similar websites gain consumers' trust. Hotel attributes performance has a strong positive moderating effect on the relationship between reviewers' attributes and consumers' trust, and the trust engendered in this way creates the psychological comfort that leads to positive behavioral outcomes. Implications for theory and practice are discussed along with suggestions for future research.     

Helpful or harmful? A double-edged sword of emoticons in online review helpfulness

Emoticons are graphic demonstrations of facial expressions. They have become a common and easy-to-use tool for online users to express ideas or feelings. Earlier research highlights the importance of emoticons in computer-mediated communications. However, limited attention has been given to the use of emoticons in online reviews. Using the Cognitive Tuning Theory as the backbone, we attempt to examine how emoticons in online reviews influence review helpfulness. One lab experiment with restaurants as the context and one empirical study with data of 4870 hotel reviews from Facebook business pages were conducted. The hypotheses were assessed via multilevel regression analysis using R programming language. Results indicate that positive emoticons enhance review helpfulness when the review is narrative-based and negative emoticons increase review helpfulness when the review is list-based. Processing fluency serves as the underlying mechanism. We discuss theoretical and practical implications.     

Asymmetric effects of online consumer reviews

Consumers tend to seek heuristic information cues to simplify the amount of information involved in tourist decisions. Accordingly, star ratings in online reviews are a critical heuristic element of the perceived evaluation of online consumer information. The objective of this article is to assess the effect of review ratings on usefulness and enjoyment. The empirical application is carried out on a sample of 5,090 reviews of 45 restaurants in London and New York. The results show that people perceive extreme ratings (positive or negative) as more useful and enjoyable than moderate ratings, giving rise to a U-shaped line, with asymmetric effects: the size of the effect of online reviews depends on whether they are positive or negative.     

A critical review of determinants of information search behavior and utilization of online reviews in decision making process (invited paper for ‘luminaries’ special issue of International Journal of Hospitality Management)

This conceptual paper provides a brief review of hospitality consumers’ information search behavior and the factors that are likely to influence their information search behavior and their utilization and processing of online reviews. This study focuses on the factors such as information overload, confusion, information processing, information presentation format, trust and evaluation mode that has not received much attention from hospitality scholars in addition to discussing the impacts of perceived risk and familiarity on information search and information processing approaches utilized by hospitality consumers. This study also discusses opportunities for hospitality researchers to empirically examine the extent to which each of the factors discussed might influence hospitality consumers information search, information processing and especially their utilization of online reviews in their decision making process.
