基于beta密度函数的信任模型
A Trust Model Based on Beta Probability Density Function
【摘要】 信任是网上商务活动成功执行的基础,通过概率论原理建立了一种基于beta概率密度函数的信任模型.该模型考虑了交易系统中关于交易者的历史交易数据,通过科学和现实地处理这些交易数据来构造交易者的信任函数.同时模型考虑了推荐信息,通过有效的传递和组合来处理这些推荐信息.此外,模型引入了比较合理的时间退化因子.
【Abstract】 Trust is the base of e-business,if there is no trust between the two who are included in the activity, the commerce will not succeed.This paper establishes a trust model which based on beta probability density function.This model concerns about the history trading data,and establish a trust function by making use of these trading data scenically and operationally.What is more,the model also concern about the recommendations,treats these recommendation information by delivering and combination.Finally,this model brings in a more reasonable time degenerating factor.
【Key words】 trust; time degenerating factor; beta probability density function;
