摘要
The television ratings provide an effective way to analyze the popularity of TV programs and audiences’watching habits.Most previous studies have analyzed the ratings from a single perspective.Few efforts have integrated analysis from different perspectives and explored the reasons for changes in ratings.In this paper,we design a visual analysis system called TVseer to analyze audience ratings from three perspectives:TV channels,TV programs,and audiences.The system can help users explore the factors that affect ratings,and assist them in decisions about program productions and schedules.There are six linked views in TVseer:the channel ratings view and program ratings view show ratings change information from the perspective of TV channels and programs respectively;the overlapping program competition view and the same-type program competition view indicate the competitive relationships among programs;the audience transfer view shows how audiences are moving among different channels;the audience group view displays audience groups based on their watching behavior.Besides,we also construct case studies and expert interviews to prove our system is useful and effective.
