@李开复 老师答案的(社会动力学)理论解释版本:FGS能够挖掘出的信息的“巨大价值”是什么?
提示:以下内容包含非常巨大的信息量,恕不做详细解释:
- 受MEP (Maximum Entropy Production)支配的社会系统演化过程具有方向性[1,2,3],社会运作效率的提升与社会网结构的自组织、复杂化是一致过程[4,5,6]。
- 微观层面上的个体互动机制(及演化)形成了宏观层面上的社会网结构演化[7,8],这过程等价于热力学过程[9,10,11]。
以上,是为什么“通过社会网传播的信息”的局域价值可能会与信息的全局价值显著不同——因为影响局部的群体互动乃至整体的社会运作效率的,首先是这种局域信息或者说“局域温度”,而不是全局价值、全局温度。
Google排序算法的主体部分(也就是不考虑根据+1调整的部分)是信息价值的绝对排名(全局信息熵、全局温度)。绝对排名的好处是具有客观性(普世价值),坏处是失去主观性(局域温度、个体行为动机)。Google当然也想弥合这两者形成一个最优结果(对Google来说,算法上并不困难),但是(邪恶的)Facebook、Twitter、...不开放自己的社交关系数据。所以。。。
结论:往大里说,FGS有机会重新定义信息的价值、并有机会找到新的组织这些信息的方式,去完成Google的未竟事业。往小里说,Facebook有机会改进现在被人诟病的“原生广告”,做出真正的“原生广告”。
