参见图1,图1为本申请实施例提供的一种征信评分确定方法流程图。
如图1所示,该方法包括步骤S100至步骤S120。
步骤S100、获取用户群,用户群包括具备社交关系的多个用户,多个用户中包含目标用户。
目标用户可以为按照现有征信评分计算模型无法计算出征信评分值,或者计算出的征信评分值不准确的用户。
为了表征用户群中各个用户之间的社交关系的远近,本实施例可以引入用户间的亲密度的概念,利用用户间的亲密度值来表征用户间社交关系的远近。亲密度值的确定可以根据两个用户间的社交通信量来确定,还可以人为进行设定等。亲密度值一般小于1。
用户群中的各个用户可以按照现有征信评分计算模型计算得到初始征信评分值,当然如果按照现有模型无法计算某个用户的征信评分值,则可以直接设定其初始征信评分值为0,或者按照与该用户具备社交关系的各个用户的初始征信评分值,确定该用户的初始征信评分值,例如,将与其具备社交关系的各个用户的初始征信评分值的平均值设定为该用户的初始征信评分值。
步骤S110、对于所述用户群中各个用户,根据与用户具有社交关系的用户的上一次迭代更新后的征信评分值,确定所述用户的当前征信评分值,迭代更新直至所述用户群中各个用户的当前征信评分值满足预置收敛结果。
步骤S120、将所述目标用户的当前征信评分值确定为目标用户的征信评分值。
通过迭代更新用户群中各个用户的征信评分值,使得用户的征信评分值整体向真实值靠拢,当确定各个用户的当前征信评分值均满足预置收敛结果时,即可认定群中各个用户的当前征信评分值已经达标,此时可以将目标用户的当前征信评分值确定为最终的征信评分值。
当然,由于各个用户的当前征信评分值均满足预置收敛结果,群中各个用户的当前征信评分值已经达标,还可以将用户群中除目标用户外的其余用户中某个用户的当前征信评分值确定为该用户的调整后的征信评分值。
本申请实施例提供的征信评分确定方法,首先获取用户群,该用户群内包括具有社交关系的多个用户,多个用户中包含目标用户,目标用户可以为征信评分缺失或不准确的用户,由于用户群内各用户具备社交关系,因此各个用户的真实征信评分相对比较接近,本申请对用户群内各个用户,根据与用户具有社交关系的用户的上一次迭代更新后的征信评分值,确定所述用户的当前征信评分值,迭代更新直至所述用户群中各个用户的当前征信评分值满足预置收敛结果,确定目标用户的征信评分值。本申请方案依靠目标用户的社交圈内其它用户的征信评分值来调整或确定目标用户的最终的征信评分值,提高了用户的征信评分的准确度。
可选的,通过上述方案可以得知,用户的征信评分值受到与该用户具备社交关系的用户的征信评分值的影响,反过来用户的征信评分值也会影响与其具备社交关系的用户的征信评分值。可以理解的是,两个具备社交关系的用户,若其社交关系越远,也即亲密度值越小,则对对方的征信评分值的影响越小。
因此,为了减少计算复杂度,在获取与目标用户具备社交关系的用户时,可以设定一个关系阈值,仅获取与目标用户的亲密度值大于关系阈值的用户。
当然,如果不考虑计算复杂度的问题,可以将与目标用户具备社交关系的所有用户均添加到用户群中。这样,按照上述方案执行完毕后,用户群中各个用户更新后的征信评分值均可以作为各自最新的征信评分值进行输出。同时对多个用户的征信评分值进行更新,使得整体征信评分值更新效率更高。
进一步地,在获取了用户群之后,还可以利用所述用户群中各个用户间的社交关系建立社交关系图。社交关系图由节点和节点间的线段组成,其中节点代表用户,节点间的线段代表两个节点所代表的用户具备直接社交关系,并且在线段上赋有表征两个节点所代表的用户间的亲密度的值。
参见图2,图2为本申请实施例公开的一个社交关系图的示意图。图2示意的社交关系图中共包含4个用户,分别为用户A、B、C、D。我们将社
交关系为分直接社交关系和间接社交关系,具备间接社交关系的两个用户的亲密度值可以设置为0。
其中,与A具备直接社交关系的用户为B和C;与B具备直接社交关系的用户为A和D;与C具备直接社交关系的用户为A;与D具备直接社交关系的用户为B。剩余的用户间的社交关系为间接社交关系。
用户A与B间的亲密度值为αab,用户A与C间的亲密度值为αac,用户B与D间的亲密度值为αbd。
通过建立目标用户的社交关系图,以图例的形式更加形象的表明了用户群中各个用户之间的社交关系。在建立社交关系图之后,后续可以对社交关系图中的各个用户执行征信评分值的更新过程。
参见图3,图3为本申请实施例公开的另一种征信评分确定方法流程图。
如图3所示,该方法包括步骤S300至步骤S330。
步骤S300、获取用户群,用户群包括具备社交关系的多个用户,多个用户中包含目标用户。
目标用户可以为按照现有征信评分计算模型无法计算出征信评分值,或者计算出的征信评分值不准确的用户。
步骤S310、对所述用户群中各个用户执行征信评分更新过程。
其中,所述征信评分更新过程包括:根据与用户具有社交关系的用户的上一次迭代更新后的征信评分值,确定所述用户的当前征信评分值。
本步骤中,依次对用户群中各个用户的征信评分值进行更新,更新时参考与用户具备社交关系的用户的征信评分值。在对用户群中各个用户的征信评分值均更新一遍后,用户的征信评分值整体向真实征信评分值靠拢。
步骤S320、判断所述用户群中各个用户的当前征信评分值是否均满足预置收敛结果;若否,返回执行步骤S310,若是,执行步骤S330。
步骤S330、将所述目标用户的当前征信评分值确定为目标用户的征信评分值。
通过迭代更新用户群中各个用户的征信评分值,使得用户的征信评分值整体向真实值靠拢,当确定各个用户的当前征信评分值均满足预置收敛结果
时,即可认定群中各个用户的当前征信评分值已经达标,此时可以将目标用户的当前征信评分值确定为最终的征信评分值。
当然,还可以将用户群中除目标用户外的其余用户的当前征信评分值确定为对应用户的调整后的征信评分值。
本实施例介绍了一种对用户群内各个用户的征信评分值进行迭代更新的具体实施方式,通过迭代更新用户群中各个用户的征信评分值,使得用户的征信评分值整体向真实值靠拢。
在本申请的又一个实施例中,详细介绍上述利用与用户具有社交关系的用户的上一次迭代更新后的征信评分值,确定所述用户的当前征信评分值的过程。
本实施例提供了一种用户征信评分值更新方程,按照如下方程对各个用户的征信评分值进行更新:
其中,N为用户群中用户总个数,为第i个用户在第t次更新后的征信评分值,αij为第i个用户与第j个用户间的亲密度值,亲密度值表征了两个用户间社交关系的远近,为第j个用户在第t-1次更新后的征信评分值,为第i个用户的初始征信评分值。
对于用户的初始征信评分值,可以按照现有的计算模型进行计算。当然,如果现有计算模型无法计算出用户的初始征信评分值,则可以设定用户的初始征信评分值为0,或者为与用户具备社交关系的用户的初始征信评分值的平均值。
可选的,在设定亲密度值时,可以设定用户i与用户j的亲密度值为αij,用户j与用户i的亲密度值为αji,αij可以等于αji,当然αij也可以不等于αji,具体设定规则根据实际需要而定。
接下来研究征信评分值的收敛情况。
将上述征信评分值更新方程按照矩阵形式表示:
其中,定义:
则征信评分值更新方程表示为:
PCS(t)=β+Q*PCS(t-1)
则有如下推导:
第一次更新:PCS(1)=β+Q*PCS(0)=β+Q*β
第二次更新:PCS(2)=β+Q*PCS(1)=β+Q(β+Q*β)=(I+Q+Q2)β
第三次更新:PCS(3)=(I+Q+Q2+Q3)β
……
因此,只要保证Qn+1收敛,PCS(n)就能够收敛。
在实际应用中,一般令每个用户与其邻居用户的亲密度和小于1,用户的邻居用户为与用户具备社交关系的用户。
需要说明的是,上述公式中我们设定用户与自身之间的亲密度值为0。至于用户的邻居用户,可以分为直接邻居用户和间接邻居用户,直接邻居用户为与用户具备直接社交关系的用户;间接邻居用户为与用户具备间接社交关系的用户。用户与直接邻居用户间的亲密度值不为0,用户与间接邻居用户间的亲密度值可以设置为0。
接下来通过一个具体实例来介绍征信评分更新过程。
仍参见图2所示,假设A、B、C、D的初始征信评分为:
βa=1=A0,βb=2=B0,βc=1=C0,βd=2=D0
αab=αac=αba=αbd=αca=αdb=0.1
第一次迭代结果为:
A1=βa+αabB0+αacC0=1.3 B1=βb+αbaA0+αbdD0=2.3
C1=βc+αcaA0=1.1 D1=βd+αdbB0=2.2
第二次迭代结果为:
A2=βa+αabB1+αacC1=1.34 B2=βb+αbaA1+αbdD1=2.35
C2=βc+αcaA1=1.13 D2=βd+αdbB1=2.23
第三次迭代结果为:
A3=βa+αabB2+αacC2=1.348 B3=βb+αbaA2+αbdD2=2.357
C3=βc+αcaA2=1.134 D3=βd+αdbB2=2.235
第四次迭代结果为:
A4=βa+αabB3+αacC3=1.3491 B4=βb+αbaA3+αbdD3=2.3583
C4=βc+αcaA3=1.1348 D4=βd+αdbB3=2.2357
在迭代到第4次时,A、B、C、D的征信评分值已经收敛到一定结果,例如,A4,B4,C4,D4已经分别很接近A3,B3,C3,D3了,再迭代下去几乎就不再改变了,A4,B4,C4,D4可以作为A、B、C、D的征信评分值的最终值进行输出。A4,B4,C4,D4与最初的A0,B0,C0,D0比起来是有变化的,这就是好友的征信评分值产生的影响。
如果A是目标用户,由于各个用户(如A、B、C、D)的当前征信评分值均满足预置收敛结果,可以将此时用户B、C、D的征信评分值B4,C4,D4分别作为用户B、C、D调整后的征信评分值。当然上述征信评分方程仅仅是一种可选形式,本领域技术人员可以在此方程的基础上进行变形、改动。
在本申请的又一个实施例中,介绍了又一种征信评分值确定方法,参见图4。
如图4所示,该方法包括步骤S400至步骤S450。
步骤S400、初始化用户群仅包含目标用户,将所述目标用户确定为指定用户。
步骤S410、获取所述指定用户的社交网络中的好友列表。
步骤S420、判断获取的好友列表中是否存在新用户,所述新用户为所述用户群中不存在的用户;若是,则执行步骤S430,若否,执行步骤S440。
步骤S430、将所述新用户添加到所述用户群中,并将所述新用户确定为指定用户,返回执行步骤S410。
步骤S440、对于所述用户群中各个用户,根据与用户具有社交关系的用户的上一次迭代更新后的征信评分值,确定所述用户的当前征信评分值,迭代更新直至所述用户群中各个用户的当前征信评分值满足预置收敛结果。
步骤S450、将所述目标用户的当前征信评分值确定为目标用户的征信评分值。
本实施例中介绍了一种获取与目标用户具备社交关系的用户群的具体实施方式,利用用户的社交网络来获取用户的好友列表,并进一步获取好友列表中各个用户的好友列表,循环执行,迭代更新直至获取不到新的用户为止。
这里,用户的社交网络可以是用户的QQ、微信、微博、Email、通讯录等等各种社交网络。
在本申请的又一个实施例中,介绍了又一种征信评分值确定方法,参见图5。
如图5所示,该方法包括步骤S500至步骤S530。
步骤S500、获取用户群,用户群包括具备社交关系的多个用户,多个用户中包含目标用户。
目标用户可以为按照现有征信评分计算模型无法计算出征信评分值,或者计算出的征信评分值不准确的用户。
步骤S510、对所述用户群中各个用户执行征信评分更新过程。
其中,所述征信评分更新过程包括:根据与用户具有社交关系的用户的上一次迭代更新后的征信评分值,确定所述用户的当前征信评分值。
步骤S520、判断所述用户群中各用户的当前征信评分值与上一征信评分值的差值是否均小于阈值,若是,执行步骤S530,若否,返回执行步骤S510。
步骤S530、将所述用户群中目标用户的当前征信评分值确定为所述目标用户的征信评分值。
本实施例介绍了一种判断征信评分值是否满足收敛结果的方式,具体地通过对比更新前后征信评分值的差值与阈值的大小关系来确定征信评分值是否满足收敛结果。
可以理解的是,通过上一实施例中介绍的征信评分值更新方程,在确定各个用户间的亲密度值之后,可以预先计算出各个用户的征信评分值的收敛值,进而可以在每次更新后对比更新后的征信评分值与收敛值,根据对比结果来确定本次更新后的征信评分值是否满足收敛结果。
