Mo­bile, Twit­ter data can be used to es­ti­mate crowd size: Study

Asian Journal - - World -

Lon­don: In an era of mo­bile in­ter­net, data is a key el­e­ment in many fields. Now re­searchers say they can even use ge­o­graph­i­cal data from mo­bile phones and Twit­ter to es­ti­mate the size of a large crowd. Over a two-month long study in Mi­lan, re­searchers from Bri­tain’s War­wick Uni­ver­sity an­a­lysed geo­tagged tweets and mo­bile phone use, based on the mo­bile data pro­vided by lo­cal car­rier. They fo­cused their study on two lo­ca­tions in the city, a foot­ball sta­dium and an air­port. Through flight sched­ules and foot­ball ticket sales, they ac­quired the num­ber of vis­i­tors and then com­pared th­ese fig­ures with mo­bile phone ac­tiv­i­ties, such as phone calls and text mes­sages, in­ter­net use, and tweets. Re­searchers said th­ese ac­tiv­i­ties fol­lowed a sim­i­lar pat­tern with the flow of vis­i­tors, which en­ables them to es­ti­mate the crowd size of an event, Xin­hua re­ported. For ex­am­ple, a to­tal of 10 foot­ball matches took place in the sta­dium dur­ing the study pe­riod, and re­searchers can use mo­bile in­ter­net data from any nine of those matches to pre­dict the num­ber of vis­i­tors at the tenth one.
