In view of the increasing popularity of online reviews and their significant impact on individual buying behavior as well as on the supply side, this study reviewed and analyzed articles related to online reviews in tourism and hospitality published in academic journals between 2004 and 2013. Based on a keyword-driven search and a content analysis, 50 articles were identified as relevant and classified into five topics. The findings revealed that (a) more than half of the analyzed articles focus on hotels and apply empirical methods based on secondary data, (b) more attention has been paid to the relationship between online reviews and online buying as well as satisfaction and online management, and (c) opinion mining of online reviews, motivation to post reviews, and the role of reviews are evenly distributed. This paper also discussed significant topical and methodological trends, contributes to an overall understanding of existing research and its limitation.

Mountain regions and peripheral communities, which often depend on few economic sectors, are among the most exposed and sensitive to climate change. Governance of such socio-economic-ecological networks plays a strong role in determining their resilience. Social processes of governance, such as collaboration between communities, can be systematically assessed through the existence and strength of connections between actors and their embeddedness in the broader socio-economic network by social network analysis (SNA). This paper examines how network governance of the tourism industry-dependent Swiss Gotthard region relates to resilience to climate change by SNA. The paper argues that economic diversification and a network structure supporting stability, flexibility, and innovation increase regional resilience to climate change. The Gotthard network has a high diversification capability due to high cohesion and close collaboration, limited innovative capacity by the existence of only two subgroups, and considerable flexibility through the centralized structure. Main weaknesses are a low density, uneven distribution of power, and a lack of integration of some supply chain sectors into the overall network.
