Study On The Influence Of The Stability Of Wisdom Of Crowds In The Valuation Task Scenario

A measure that aggregates the central tendency of different individuals will be more accurate than the results of single individuals,which is called wisdom of crowds.With the development of network technology and the convenience of data acquisition,the study of wisdom of crowds is becoming more and more in-depth and has become a hot spot of current research.Among the researches on the influential factors of wisdom of crowds,most of them focus on the external factors such as the surrounding environment and social influence,while the researches on the internal factors of wisdom of crowds only focus on the single factor of the group size,and there are few studies on the comprehensive internal factors of wisdom of crowds.In order to explore the valuation task groups in the scene of intrinsic factor’s influence on the wisdom of crowds,in this paper,based on the review of literatures at home and abroad,from the individual’s quality and quantity of the two factors of internal,explore the smart individuals and group size on the influence of wisdom of crowds,on the basis of identify smart individual of model building,smart individuals for the stability of the further analysis,so as to improve the robustness of wisdom of crowds.For the choice of wisdom measure,widely used in the past research literature polymerization methods of the mean,median,on the basis of the proposed two new correction mean and median,two influence factors according to the scale of smart individuals and groups to build four polymerization methods on the research of the effect and efficiency of the wisdom of crowds model.By means of experimental research,three valuation task scenarios were designed,individuals were gathered for experiments and experimental data were collected,and the relationship between various influencing factors was analyzed.The results show that(1)smart individuals can improve the efficiency of wisdom of crowd in multiple task scenarios;(2)in each task scene there are always smart individuals to provide positive support to the group,smart individuals have better stability;(3)the relationship between group size and wisdom of crowds is not a simple linear growth,when the group increases to a certain size,the wisdom of the group will tend to flat;(4)the aggregation method of the revised wisdom of the group can effectively reduce the deviation of the results of the group,but the effect on the effectiveness of the wisdom of crowd is very small.In this paper,the influencing factors of wisdom of crowd are studied in the valuation task scenario.Considering the two main factors of individual quality and number,a modified aggregation method is proposed to compare and study the influence of smart individuals and group size on wisdom of crowd,and to find out the internal connection between them,so as to improve the validity of wisdom of crowd.
