203、获取待质检数据,待质检数据为文本数据;
服务器获取为文本数据的待质检数据。需要强调的是,为进一步保证上述待质检数据的私密和安全性,上述待质检数据还可以存储于一区块链的节点中。
待质检数据为查询销售行为、查询重要信息和确认问题责任的重要依据,待质检数据可以为证券场景下的待质检数据,也可以为保险场景下的待质检数据等,本实施例主要以保险场景下的待质检数据进行说明,待质检数据具体可以为“在您攒钱享受18%收益的同时,就可以直接享有了,您放心,这个不需要您额外花费一分钱,您可以放心地享有。”和“行,那这边给您最后说一下,因为您是积累高端年金合作客户,今后的话,我们第一次会有一个年金客户身份的一个经济审核。”等文本数据。
204、将待质检数据输入第一阶段的违规数据识别模型中,生成二分类数据,第一阶段的违规数据识别模型为二分类模型;
服务器将待质检数据输入为二分类模型的第一阶段的违规数据识别模型中进行违规数据识别,生成二分类数据。
在对待质检数据进行质检时,主要通过两个阶段对待质检数据进行质检,在第一阶段进行质检时,采用违规数据识别模型进行质检,服务器先将待质检数据输入违规数据识别模型中,进行违规数据与无违规数据的识别,从而生成二分类数据,其中,二分类数据为标签数据,用于指示待质检数据是否违规。
在一实施例中,假设待质检数据为“在您攒钱享受18%收益的同时,就可以直接享有了,您放心,这个不需要您额外花费一分钱,您可以放心地享有。”,在第一阶段,服务器将该待质检数据输入违规数据识别模型中进行违规数据识别,生成为“违规数据”的二分类数据;在另一实施例中,假设待质检数据为“行,那这边给您最后说一下,因为您是积累高端年金合作客户,今后的话,我们第一次会有一个年金客户身份的一个经济审核。”,服务器将该待质检数据输入违规数据识别模型中,生成为“无违规数据”的二分类数据。
具体的,服务器将待质检数据输入为二分类模型的第一阶段的违规数据识别模型,首先在循环神经网络中对待质检数据进行特征提取,生成第一文本特征向量;然后服务器将第一文本特征向量输入该模型的全连接层中,并结合激活函数进行数据处理,生成二分类数据。
例如,待质检数据为“在您攒钱享受18%收益的同时,就可以直接享有了,您放心,这个不需要您额外花费一分钱,您可以放心地享有。”,服务器首先将该待质检数据输入循环神经网络中进行特征提取,生成第一文本特征向量为[y 1 y 2 y 3 ... y m],然后服务器将该第一文本特征向量输入该模型中的全连接层中结合激活函数,生成二分类数据“违规数据”。
服务器将待质检数据输入为二分类模型的第一阶段的违规数据识别模型,首先在循环 神经网络中对待质检数据进行特征提取,生成第一文本特征向量包括:
服务器将待质检数据输入为二分类模型的第一阶段的违规数据识别模型中,结合预置的向量空间模型生成文本向量矩阵;然后服务器将文本向量矩阵输入循环神经网络中结合激活函数进行特征提取,生成第一文本特征向量。
假设待质检数据为“在您攒钱享受18%收益的同时,就可以直接享有了,您放心,这个不需要您额外花费一分钱,您可以放心地享有。”,服务器将该待质检数据输入第一阶段的违规数据识别模型中,生成文本向量矩阵为:
Figure PCTCN2021109696-appb-000001
服务器将该文本向量矩阵输入循环神经网络中结合激活函数生成第一文本特征向量[y 1 y 2 y 3 ... y m]。需要说明的是,在采用循环神经网络结合激活函数将文本向量矩阵处理为文本特征向量的过程中,会删除冗余的文本特征,因此第一文本特征向量中的m小于文本向量矩阵中的k。
然后服务器将第一文本特征向量输入该模型的全连接层中,并结合激活函数进行数据处理,生成二分类数据包括:
服务器将第一文本特征向量输入全连接层中进行特征加权,生成文本分类得分;然后服务器结合激活函数对文本分类得分进行计算,生成目标分类概率,并基于目标分类概率确定二分类数据。
在本实施例中,假设第一文本特征向量为[y 1 y 2 y 3 ... y m],服务器将该第一文本特征向量输入全连接层中,按照预置加权公式进行加权,加权公式为:
S i=w i·y+b i
其中,i=0或者i=1,w i为全连接层中的预置的权重,b i为全连接层中的预置的偏置,服务器经过该计算,生成文本分类得分,然后采用激活函数对文本分类得分进行计算,在本实施例中,激活函数为softmax函数,具体的为:
Figure PCTCN2021109696-appb-000002
经过该激活函数,生成目标分类概率,由于softmax函数的概率和为1,因此在二分类中,只需要计算出其中一个分类概率,即可得到另一个分类概率,即1-P i,服务器最后基于目标分类概率确定二分类数据。
205、根据二分类数据对待质检数据添加头部标识符和尾部标识符,并输入第二阶段的违规数据分类模型中,结合注意力机制进行违规数据分类,生成违规类型数据,第二阶段的违规数据分类模型为BERT模型;
服务器根据二分类数据在待质检数据的基础上添加头部标识符和尾部标识符,并将添加头部标识符和尾部标识符后的待质检数据输入为BERT模型的第二阶段的违规数据分类模型,结合注意力机制进行违规标签的分类,生成违规类型数据。
其中,BERT模型的全称为Bidirectional encoder representations from transformers,当二分类数据符合第二阶段的质检标准时,服务器在待质检数据的基础上添加用于分类的头部标识符,即头部token,以及用于语句分类的尾部标识符,即尾部token,然后将添加头部标识符和尾部标识符的待质检数据输入第二阶段的违规数据分类模 型中,结合注意力机制、头部标识符和尾部标识符进行违规数据分类,生成违规类型数据。
具体的,服务器首先判断二分类数据是否为违规数据;若服务器判定二分类数据为违规数据,服务器则对待质检数据进行添加头部标识符和尾部标识符的处理,并将处理后的待质检数据输入为BERT模型第二阶段的违规数据分类模型,结合注意力机制、头部标识符和尾部标识符进行违规数据分类,生成违规类型数据。
若服务器判定二分类数据为违规数据,服务器则对待质检数据进行添加头部标识符和尾部标识符的处理,并将处理后的待质检数据输入为BERT模型第二阶段的违规数据分类模型,结合注意力机制、头部标识符和尾部标识符进行违规数据分类,生成违规类型数据包括:
若二分类数据为违规数据,服务器则为待质检数据添加头部标识符和尾部标识符,生成处理后的待质检数据;服务器将处理后的待质检数据输入第二阶段的违规数据分类模型,生成第二文本特征向量,第二文本特征向量包括多个单词特征向量;服务器分别读取每两个相邻单词特征向量的向量距离,得到多个向量距离;服务器结合注意力机制将多个向量距离转换为1,并结合头部标识符和尾部标识符对第二文本特征向量进行违规数据分类,生成违规类型数据。
假设基于“在您攒钱享受18%收益的同时,就可以直接享有了,您放心,这个不需要您额外花费一分钱,您可以放心地享有。”的待质检数据得到的二分类数据为违规数据,服务器则在该待质检数据的头部添加头部标识符,在待质检数据的尾部添加尾部标识符,从而生成处理后的待质检数据为“[CLS]在您攒钱享受18%收益的同时,就可以直接享有了,您放心,这个不需要您额外花费一分钱,您可以放心地享有。[SEP]”。其中头部标识符[CLS]为for classification,该头部标识符用于分类的临时标记,尾部标识符[SEP]为for segmentation,该尾部标识符用于分割不同语句的临时标记。服务器将该处理后的待质检数据输入违规数据分类模型中,生成第二文本特征向量,服务器分别读取每两个相邻单词特征向量的向量距离,得到多个向量距离,服务器再结合注意力机制将每个向量距离转换为1,从而能够结合该模型所有层中的左右两侧语境进行分类。结合[CLS]算法的待质检数据生成的第二文本特征向量包括权重,其中权重越大,结合注意力机制对应的注意力越多,例如,“这个”单词文本特征向量对应的权重较小,因此对应的注意力较少,在后面进行分类识别时可以忽略不计该特征向量。最后服务器结合注意力机制对第二文本特征向量进行分类识别,生成违规类型数据“误导不花钱”。在其他实施例中,违规类型数据还可以为误导钱可以随取随用、混淆返还年限等。
206、将违规类型数据传输至目标终端,目标终端为发出待质检数据的终端。
服务器在得到违规类型数据之后,将该违规类型数据传输至发出待质检数据的目标终端。
服务器将违规类型数据传输至目标终端,终端为不同客户的终端,目标终端为发出待质检数据的客户终端,这种质检方式能够打破时间和地域的限制,从而达成与客户交流、查询销售人员行为的目的。
本申请实施例中,利用第一阶段的质检模型生成二分类数据,当二分类数据为违规数据时,再通过第二阶段的质检模型进行违规分类,生成违规类型数据;通过使用两个阶段的质检模型,先识别违规数据,再识别违规数据对应的违规类型数据,使得第二阶段的质检模型能够专注于违规数据的分类,解决了质检数据不均衡的问题,从而提高了质检的准确率。
