In this thesis, we introduce a trust framework which captures both human trust level and its uncertainty, and also present advantages of using the trust framework to intensify the dependability of HSNS, namely filtering information, increasing the efficiency of pharmacy marketing, and modeling how to monitor reliability of health information. Several experiments which were conducted on real health social networks validate the applicability of the trust framework in the real scenarios.en-USOnline social networks -- AnalysisMedical informatics -- Research -- MethodologyConsumer educationMedicine -- Computer network resources -- ResearchComputer software -- Human factors -- ResearchPharmacy -- PracticeDrugs -- MarketingTrust -- Research -- MethodologyConsumer protectionInternet in medicine -- Marketing
