spir-8794	Kümpel, Anna Sophie; Haim, Mario	Popularity indicators in online media. A review of research on the effects of metric user information	2016.0	4	.pdf	application/pdf	1264	59	43	These  popularity  indicators  (PIs),  which  we  define  as  metric   information  about  users’  behavior  or  their  evaluations  of  entities,  serve  as  social  signals   for  users  who  are  confronted  with  them.   As  prior  research  shows,  PIs  are  thereby  able   to  influence  users’  perceptions  of  the  evaluated  object  and  might  thus  affect  their   subsequent  decisions.    	cache/spir-8794.pdf	txt/spir-8794.txt
