Purpose The purpose of this study is to explore the effect of two types of presentation formats (textual and imagery) involving online restaurant reviews (ORRs). The study examines ORRs on the basis of review usefulness and review enjoyment; the study investigates the effects of the two presentation formats on review usefulness and review enjoyment. Design/methodology/approach Data from 1,776 reviews were collected from Yelp.com using a Web data-harvesting technique. Hypothesized relations in th

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

Sharing economy businesses require extensive trust-based communication between users and service providers to facilitate users’ positive persuasion processes. Based on Aristotle’s rhetorical theory, this study identifies three key persuasive cues (credibility, emotional bonding, and accommodation characteristics) and validates their roles in establishing users’ trust in an Airbnb setting. The moderating role of interactivity is further analyzed. Research findings from a survey sample of 171 Airb

CouchSurfing is a free social-network-based online hospitality exchange network, aptly representing a new sharing economy phenomenon. Based on social capital theory and previous literature, this study attempts to answer why hosts help strangers without any expected economic benefit within online hospitality exchange networks. An empirical study based on a Web survey conducted with CouchSurfing hosts reveals that the most identified antecedents (enjoy helping, shared narratives, desire to make fr

Virtual worlds are relatively nascent IT platforms with the potential to radically transform business processes and generate significant payoffs. However, in striving to achieve specific outcomes, firms may incur significant risks. Although many companies claim to have attained substantial benefits from their virtual world initiatives, many others have recently scaled down or even abandoned their experimental virtual world projects. This paper assesses the value proposition of virtual world init

This study provides an applicable methodological procedure applying Artificial Intelligence (AI)-based supervised Machine Learning (ML) algorithms in detecting fake reviews of online review platforms and identifies the best ML algorithm as well as the most critical fake review determinants for a given restaurant review dataset. Our empirical findings from analyzing 16 determinants (review-related, reviewer-related, and linguistic attributes) measured from over 43,000 online restaurant reviews re

Abstract In spite of diverse measures by national governments and destination marketing organizations (DMOs), the statistics related to international tourist destinations, including those of independent travelers, show that the rankings of the most popular tourist destinations have undergone minimal changes over the past decade. The aim of this study is to understand the factors that prevent independent travelers from selecting smaller regions (i.e., relatively less popular destinations) and exa

Bike sharing has become a central theme in discussions regarding the construction of smart transportation cities. Privately-run bike sharing companies, however, have had difficulty in expanding into overseas markets, which has led them to partner with the public sector. As little research has examined the role of partnerships between private and public sectors in the bike sharing platform context, we focus on the overseas expansion of Mobike Korea, a representative privately-run bike sharing com

We delineate an integrative view of inter-organizational knowledge transfer (IOKT) in the upstream supply chain relationship from a buyer's perspective. For this purpose, we suggest that the concept of IOKT can be classified into the source and the recipient type of knowledge transfer according to the direction of knowledge flow. A three-stage model (motivation-behaviors-performance) is adopted to examine the relationships between IOKT and its antecedent factors, and, in turn, between IOKT and o
