讲座摘要:

Friendship formation is of central importance to online social network sites and to society。 In this study, we investigate whether and how displaying things in common (TIC) between users (mutual hometown, interest, education, work, city) may encourage friendship formation。 Displaying TIC online may update an individual's belief about the shared similarity with another and reduce information friction that may be hard to overcome in offline communication。 In collaboration with a large online social network, we design and implement a randomized field experiment involving over 50 million viewer-profile pairs, which randomly varies the prominence of things in common information when a user (viewer) is browsing a non-friend's profile。 The dyad-level exogenous variation, orthogonal to any unobserved factors in viewer-profile's network, allows us to cleanly isolate the role of individuals' preference (over TIC) in driving network formation and homophily。 We find that displaying TIC to the viewers may significantly increase their probability of sending a friend request and forming a friendship, and especially effective for viewer-profile pairs who have little in common (with no mutual friends and only one or two things in common)。 Such findings suggest that information intervention is effective in encouraging the formation of weak ties, and also provide the first experimental evidence on the role of individuals' preference (versus structural factors) in network formation。 We further explore the heterogeneity in the effect and demonstrate that displaying TIC could improve friendship formation for a wide range of viewers with different characteristics。 Finally, we propose an information-theoretic model to characterize the belief update process underlying a viewer’s decision, and provide evidence that displaying TIC is more effective when the TIC information is more surprising to the viewer。 The insights and information-theoretical framework can guide the optimal design of information display in friendship formation process。Our study offersactionableinsightstosocial networksand policy makers on the design ofinformationinterventionto encouragefriendshipformationand improve the diversity of thefriendship,at bothanaggregateandanindividual level。

大发红黑大战Tianshu Sun isthe Robert R. DocksonAssistant Professorof Business Administrationat USC Marshall School of Business,withajoint appointmentinthe Department ofComputerScience. Tianshu's research conductedincollaborationwithleading privateand public sector platformsaddresses how firms can use businessanalyticsand large-scale field experimentsinconjunctionwithbig datato improve business decisions. His current research focuses on understanding 1) how digital platforms can use IT-enabled and data-driven interventions to influence social sharing among individuals, and 2) how organizations can leverage mobile and Internet of Things to integrate individuals' online and offline experience. Tianshu has worked closelywithavariety of leading technology companiesinUSand Chinaincluding Facebook, Alibaba, NetEase,Adobe, LivingSocial and Collagec.om. Many findings from these studies have been implemented by collaborating organizations. Tianshu has given over 70 talksat top universities (e.g. Wharton, MIT, Stanford, CMU, NYU)andinternational conferences,and has research papers publishedin top journalsincluding ManagementScience,Information Systems Researchand Journal of Health Economics. Tianshu's research has received nine Best PaperAwards (ICIS, WISE, CIST, INFORMS),and has been supported by grants from theAdobe, Soros Foundationand MarketingScienceInstitute. Tianshu has developed the first Big Datacourseat USC Marshall,andalso regularly spoken on topics related to Digital Experimentation, Big Dataand Platform Ecosystems to industry executives and policy makers.
