具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
本实施例提供的症状数据处理方法,可应用在如图1的应用环境中,其中,客户端与服务端进行通信。其中,客户端包括但不限于各种个人计算机、笔记本电脑、智能手机、平板电脑和便携式可穿戴设备。服务端可以用独立的服务器或者是多个服务器组成的服务器集群来实现。
在一实施例中,如图2所示,提供一种症状数据处理方法,以该方法应用在图1中的服务端为例进行说明,包括如下步骤:
S10、获取症状数据。
本实施例中,症状数据处理方法可以在症状数据处理装置上执行。症状数据可以指患者自行在症状数据处理装置输入的数据。示意性的,患者首先输入自己的一个症状。症状数据处理装置会询问该症状的属性(持续时间和发作特点),然后根据输入的症状推荐患者可能有的其他症状。若患者肯定了该症状,则同样询问该症状的相关属性,否则询问下一个症状。当患者确定已完整描述其所有的症状后,可以通过点击“确认”按钮,完成症状数据的提交。在一些情况下,症状数据也可由分诊员辅助输入。
S20、通过预设BERT编码器将所述症状数据处理为表征向量,所述表征向量基于所述症状数据中的症状特征数据而生成;所述症状特征数据包括症状名称和症状属性;所述预设BERT编码器经预训练任务训练后获得;所述预训练任务用于确定所述表征向量与所述症状特征数据之间的关联关系。
本实施例中,预设BERT(Bidirectional Encoder Representations from Transformers,双向转换编码)编码器是基于现有的BERT模型(参见谷歌公司2018年发表的论文《Pre-training of Deep Bidirectional Transformers for Language Understanding》)改进后获得。在此处,预设BERT编码器是经预训练任务训练后获得的。预训练任务为自定义任务,该预训练任务定义为根据当前的表征向量推测该表征向量包含的症状名称及症状属性。预训练任务可以确保预设BERT编码器能够学习到输出的表征向量包含的信息,也即是,通过预训练任务确定表征向量与症状特征数据之间的关联关系。需要注意的是,在此处,关联关系体现在预设BERT编码器的模型参数之中。这样,能够准确地将症状名称和症状属性转换成一个整体的向量,即表征向量。生成的表征向量的数量与症状数据中的症状数量相等。也即是,症状数据中有多少个症状,则生成相同数量且对应的表征向量。
预设BERT编码器是预先经大量病历数据(与步骤S10的类型相同)训练后获得的。因而,生成的表征向量,除了包含输入的症状数据的特征外,还包含了预设BERT编码器预测的与症状数据相关的关联特征。
S30、将所述表征向量输入预设TextCNN模型,获取所述预设TextCNN模型输出的分类结果。
本实施例中,预设TextCNN模型(文本卷积神经网络)可以基于现有的TextCNN模型改进后获得。相较于现有的TextCNN模型,预设TextCNN模型输入的是经预设BERT编码器处理后生成的表征向量,而非随机初始化的词向量。在输入阶段,症状数据生成的所有表征向量均作为预设TextCNN模型的输入数据。在模型计算阶段,使用多个卷积核对输入数据进行卷积,在池化层中池化,池化层的输出连接全连接网络单元,最后使用softmax激活函数输出每一个分类的概率。在一示例中,预设TextCNN模型可以是二分类模型,其分类结果用于判定患者是否患有危重疾病。
步骤S10-S30中,通过获取症状数据,以获得患者实时输入的原始数据。通过预设BERT编码器将所述症状数据处理为表征向量,所述表征向量基于所述症状数据中的症状特征数据而生成;所述症状特征数据包括症状名称和症状属性;所述预设BERT编码器经预训练任务训练后获得;所述预训练任务用于确定所述表征向量与所述症状特征数据之间的关联关系,在此处,通过预设BERT编码器将症状数据处理为表征向量,可以更好地提取出症状数据的特征,获得的表征向量包含的信息量更多,有利于提高分类结果的准确率。将所 述表征向量输入预设TextCNN模型,获取所述预设TextCNN模型输出的分类结果,在此处,通过TextCNN模型的处理,可以准确识别出症状数据对应的分类结果,也即是提高分类结果的准确率。
可选的,如图3所示,步骤S10,即所述获取症状数据,包括:
S101、获取第一症状数据。
第一症状数据指的是患者输入的第一个症状的症状名称和症状属性。如第一症状数据的症状名称为“咳嗽”,相应的属性数据包括“咳嗽三天”和“咳嗽带血丝”。一般情况下,一个症状名称与一个或多个属性数据关联。
S102、根据所述第一症状数据输出相关症状提示。
在获取到第一症状数据(对患者而言,则是完成第一症状数据的输入)之后,可以根据当前第一症状数据推荐患者可能存在的其他症状(可以使用常规的概率模型进行推荐),并生成相关症状提示。在一示例中,相关症状提示可以表示为:您除了“咳嗽”,是否还有“发热”的症状。
S103、基于所述相关症状提示获取第二症状数据;
在输出相关症状提示时,同时输出相应的选择框,分别为“是”和“否”。当患者选“是”时,则进行第二症状数据的收集。第二症状数据的获取方式与第一症状数据的获取方式基本相同,均为患者的输入数据。当患者选“否”时,则不收集当前相关症状提示所对应的第二症状数据。
需要注意的是,输出的相关症状提示的数量可以大于一。也就是说,收集到的第二症状数据可以大于一。在一些患者的症状数据中,可能包含的症状为3-5种。
S104、在确定症状数据收集完毕后,完成所述症状数据的获取,所述症状数据包括所述第一症状数据和所述第二症状数据。
当患者判断自己描述的症状已经是完整的,则可以点击“确认”按钮,以确定症状数据收集完毕。一般情况下,在所有症状数据中,只有一个第一症状数据,而第二症状数据的个数可以是任意非负整数,即可以是零或正整数。
步骤S101-S104中,获取第一症状数据,在此处,可以按照症状的不同逐步收集患者的症状数据,若存在多个症状数据,一般情况下,第一症状数据的重要度最高。根据所述第一症状数据输出相关症状提示,以确定患者是否存在与第一症状(即第一症状数据所对应的症状名称)相关的其他症状。基于所述相关症状提示获取第二症状数据,以进一步收集患者的症状数据(在此处,第二症状数据指的是除第一症状数据外的其他症状数据)。在确定症状数据收集完毕后,完成所述症状数据的获取,所述症状数据包括所述第一症状数据和所述第二症状数据,由此,可以获得比较详尽的症状数据,提高分类结果的准确性。
可选的,如图4所示,步骤S20,即所述通过预设BERT编码器将所述症状数据处理为表征向量,所述表征向量基于症状名称和症状属性而生成之前,还包括:
S201、建立预训练任务,使用word2vec模型将症状样本处理为若干个词向量,所述词向量包括基于症状名称生成的第一词向量,基于症状属性生成的第二词向量;
S202、将所述若干个词向量输入初始BERT网络模型,获取所述初始BERT网络模型输出的训练表征向量;
S203、根据所述训练表征向量计算所述初始BERT网络模型的损失值;
S204、若所述损失值处于预设范围之外,调整所述初始BERT网络模型的模型参数,并重新计算所述症状样本的训练表征向量;
S205、若所述损失值处于预设范围之内,则所述预训练任务训练完毕,训练完毕后的所述初始BERT网络模型即为所述预设BERT编码器。
本实施例中,预训练任务主要用于执行步骤S202-S204的循环迭代计算。在循环迭代计算之前,需要通过word2vec模型将症状样本转化为词向量。word2vec模型是一种用于 产生词向量的模型。在一示例中,症状数据为{咳嗽:三天;带血丝},经word2vec模型转换后可以得到词向量emb1(咳嗽)、emb2(三天)和emb3(带血丝)。在此处,emb1为第一词向量,emb2和emb3为第二词向量。症状样本指的是用于训练初始BERT网络模型的训练数据,一般为某个地区的历史症状数据。
在获得词向量后,可以将各个词向量作为输入数据输入初始BERT网络模型,并生成训练表征向量,并计算相应的损失值。具体的,损失值可由损失函数计算获得。该损失函数定义为:
Figure PCTCN2020124221-appb-000001
上式中,L(Vs,sym (n))为第n个症状的损失值;sym (n)表示症状列表中的第n个症状;Vs表示整体的表征向量;
Figure PCTCN2020124221-appb-000002
为第n个症状在表征向量中的损失项,
Figure PCTCN2020124221-appb-000003
为其他症状在表征向量中的损失项。通过损失函数可知,出现在表征向量里的症状,其损失值应该尽可能小,反之损失值应尽可能大。
预设范围可以根据实际需要进行调节。若损失值处于预设范围之内,则说明初始BERT网络模型已收敛,此时预训练任务训练完毕。训练完毕后的初始BERT网络模型即为预设BERT编码器。
步骤S201-S205中,建立预训练任务,使用word2vec模型将症状样本处理为若干个词向量,所述词向量包括基于症状名称生成的第一词向量,基于症状属性生成的第二词向量,以获得初始BERT网络模型的输入数据。将所述若干个词向量输入初始BERT网络模型,获取所述初始BERT网络模型输出的训练表征向量,以执行初始BERT网络模型的训练步骤。根据所述训练表征向量计算所述初始BERT网络模型的损失值,所获得的损失值可以用于调整模型参数及判断模型是否收敛。若所述损失值处于预设范围之外,调整所述初始BERT网络模型的模型参数,并重新计算所述症状样本的训练表征向量,以在模型未收敛时,进行迭代计算。若所述损失值处于预设范围之内,则所述预训练任务训练完毕,训练完毕后的所述初始BERT网络模型即为所述预设BERT编码器,在此处,获得了可用于生成表征向量的预设BERT编码器。
可选的,如图5所示,步骤S10之后,即所述获取症状数据之后,还包括:
S11、根据所述症状数据生成句向量;
S12、将所述句向量与本地病历库的病历句向量比较,计算余弦相似度;
S13、根据所述余弦相似度选取指定个数的匹配病历;
S14、获取所述匹配病历所属的就诊科室,将出现频次最高的就诊科室确定为推荐科室。
本实施例中,可以使用预设BERT编码器将症状数据处理为词向量(表征向量可以拆分为多个词向量),再结合本地病历库的TF-IDF值生成句向量。
已知症状数据的句向量和本地病历库中的病历句向量(可以是部分或全部),可以计算出相应的余弦相似度。余弦相似度高,则说明该病历与当前的症状数据相似度高。在计算完所有的余弦相似度后,可以按余弦相似度从高到低排序,选取排序在先的指定个数的匹配病历。在此处,指定个数可以根据实际需要进行设置,如可以是10个。
在选取出匹配病历后,可以获取各个匹配病历所属的就诊科室。每个匹配病历都有对应的就诊科室。示意性的,匹配病历与就诊科室的匹配关系可以表示为:
匹配病历1——就诊科室1;
匹配病历2——就诊科室3;
匹配病历3——就诊科室2;
……;
匹配病历10——就诊科室1。
可以将出现频次最高的就诊科室确定为推荐科室。推荐科室即为建议患者就诊的科室。
步骤S11-S14中,根据所述症状数据生成句向量,以结合本地数据的特点生成句向量。将所述句向量与本地病历库的病历句向量比较,计算余弦相似度,通过余弦相似度可以比较本地病历库中的病历句向量对应的病历与症状数据的相似度。根据所述余弦相似度选取指定个数的匹配病历,以获得相似度最高的匹配病历。获取所述匹配病历所属的就诊科室,将出现频次最高的就诊科室确定为推荐科室,以帮助患者选择最适合的科室。
可选的,如图6所示,步骤S12之前,即所述将所述句向量与本地病历库的病历句向量比较,计算余弦相似度之前,还包括:
S121、获取本地病历库的病历数据;
S122、使用所述预设BERT编码器处理所述病历数据,生成症状词向量查询词表,所述症状词向量查询词表包括每一症状的症状词向量;
S123、计算所述症状词向量的TF-IDF值;
S124、根据所述症状词向量和所述TF-IDF值生成每份病历的病历句向量。
本实施例中,病历数据与步骤S10中症状数据同属于同一地区的患者就诊数据。步骤S122中的预设BERT编码器与步骤S20中的预设BERT编码器训练方式相同,但输出形式略有不同。步骤S122中的预设BERT编码器输出的是症状词向量(W emb),该词向量的维度为[1,1024]。然后,计算每个症状词向量对应的TF-IDF(term frequency–inverse document frequency,基于词频的逆文本频率指数)值,并将该TF-IDF值设置为该词向量的权重。TF-IDF值用于评估症状数据中的某个症状描述(词向量)对于病历数据(句向量)的重要程度。
病历句向量可通过以下公式进行转换:
Figure PCTCN2020124221-appb-000004
其中,S emb为病历句向量,
Figure PCTCN2020124221-appb-000005
为第i个症状词向量,TF-IDF i为第i个症状词向量对应的TF-IDF值,k为病历中的症状总数量。
同样的,症状数据也可以采用步骤S122-S124生成相应的句向量。
步骤S121-S124中,获取本地病历库的病历数据,在此处,本地病历库为预先构建的用于存储本地病历数据的数据库,可以用于与步骤S10的症状数据比较。使用所述预设BERT编码器处理所述病历数据,生成症状词向量查询词表,所述症状词向量查询词表包括每一症状的症状词向量,在此处,将病历数据处理为向量形式,便于进行比较。计算所述症状词向量的TF-IDF值,在此处,TF-IDF值被设置为症状词向量在句向量中的权重。根据所述症状词向量和所述TF-IDF值生成每份病历的病历句向量,获得的病历句向量可与症状数据的句向量进行比较(通过计算余弦相似度),确定彼此的相似程度。
