ELECTRONIC WORD-OF-MOUTH: APPLICATIONS IN PRODUCT RECOMMENDATION AND CRISIS INFORMATION DISSEMINATION

Electronic word-of-mouth (eWOM) plays a central role starting from product recommendations to social awareness, which is the quintessence of this thesis. It contains three essays. The first one aims to study how eWOM, in the form of user comments, is beneficial in recommendations of high-scale products like mobile applications. The other two essays investigate the role of eWOM in information diffusion in the context of online social networks. While in the second essay, the factors impacting retweetability have been examined, the third essay investigates hashtag co-occurrence in a tweet. Overall, eWOM in the field of app recommendation and information diffusion on Twitter at the time of crisis have been critically investigated, which will not only lead to deep understanding of eWOM in emerging domains, but more importantly, provides practical implications for efficient policy making in product recommendation, advertisement, and information diffusion.
