下面对本申请实施例进行详细介绍。
请参阅图2A，图2A是本申请实施例提供的一种问答方法的流程示意图，应用于电子设备，所述方法包括：
步骤201：基于用户输入的提问语句确定多个医疗属性信息。
其中，本申请实施例可应用于智慧城市中，具体可涉及智慧城市中的智慧医疗领域中，智慧医疗的发展有利于改善医疗服务，以推动智慧城市的建设，将城市的系统与医疗服务进行打通以及集成，有利于提高整个城市资源的效率，有利于改善用户生活质量，以增加用户的生活便利性。
其中，上述提问语句可以是用户通过文字、语音、视频等方式输入的。上述每个所述 医疗属性信息包括医疗实体名称以及特异性生理参数，实体名称包括药品名称、食物名称、症状名称、人体各器官名称等等。特异性生理参数包括患者血压值、患者血糖值、患者病程时间(如视力模糊三天)、患者病灶部位(如左脚浮肿)等等。
举例说明，例如用户的提问语句例如可以为“我的血糖13，血压150/120，体重80，二甲双胍应该用多大剂量？饮食有什么忌口？”，该提问语句中的医疗实体名称包括“二甲双胍”，特异性生理参数“血糖13”、“血压150/120”、“体重80”。
可选地，为了增强用户的隐私性，在具体处理中，可将上述医疗属性信息存储于区块链中，本申请实施例中所指区块链是分布式数据存储、点对点传输、共识机制、加密算法等计算机技术的新型应用模式。区块链(Blockchain)，本质上是一个去中心化的数据库，是一串使用密码学方法相关联产生的数据块，每一个数据块中包含了一批次网络交易的信息，用于验证其信息的有效性(防伪)和生成下一个区块。区块链可以包括区块链底层平台、平台产品服务层以及应用服务层等。
步骤202：对所述提问语句进行预处理，得到多个待确定的提问意图。
进一步地，电子设备中可包括数据库，该数据库中可包括多个预设提问意图，该预设提问意图可由用户自行设置或者系统默认，上述预处理可为用户自行设置或者系统默认，具体地，可通过识别提问语句，得到提问语句的语义，然后从多个预设提问意图中查找包括提问语句的语义的预设提问意图，最后，可将查找到的预设提问意图作为多个待确定的提问意图。
步骤203：确定所述多个待确定的提问意图与所述多个医疗属性信息的相关性。
其中，关联性可以用二元数值表示，例如1和0，1表示相关，0表示不相关，还可以用除1和0之外的其他数值表示。关联性还可以用一个数值范围表示，例如0～1，0表示不相关，1表示最相关。
步骤204：基于所述相关性从所述多个待确定的提问意图中确定目标提问意图。
其中，目标提问意图例如可以为与每个医疗属性信息的相关性均大于或等于第一预设阈值的待确定的提问意图，也可以为与至少一个医疗属性信息的相关性大于或等于第二预设阈值待确定的提问意图，第一预设阈值以及第二预设阈值可为用户自行设置或者系统默认，另外，该第一预设阈值可以与第二预设阈值相等，也可以不相等；目标提问意图可以是一个，也可以是多个，在此不做限定。
步骤205：从所述目标提问意图关联的多个待确定的回答语句中，确定所述提问语句的目标回答语句。
进一步地，从所述目标提问意图关联的多个待确定的回答语句中，确定所述提问语句的目标回答语句，可以为确定该提问语句与每个待确定的回答语句的匹配度，通过该提问语句与每个待确定的回答语句的匹配度确定目标回答语句。
可以看出，在本申请实施例中，电子设备基于用户输入的提问语句确定多个医疗属性信息，每个医疗属性信息包括医疗实体名称以及特异性生理参数；对提问语句进行预处理，得到多个待确定的提问意图；确定多个待确定的提问意图与多个医疗属性信息的相关性； 基于相关性从多个待确定的提问意图中确定目标提问意图；从目标提问意图关联的多个待确定的回答语句中，确定提问语句的目标回答语句；不需要用户在医疗问答系统中通过目录方式逐级查找自己所需问题的答案，直接给出目标回答语句，通过目标回答语句就可确定自己所需问题的答案，同时还减少了查找搜索答案的流程，不仅提高了用户准确找到自己所需答案的速度，而且还提高了答案的准确性。
在本申请的一实现方式中，所述基于用户输入的提问语句确定多个医疗属性信息，包括：
从用户输入的提问语句中提取得到多个医疗属性关键词；
将每个所述医疗属性关键词嵌入到向量空间，得到多个医疗属性词向量；
通过第一隐层将所述多个医疗属性词向量转化为一维列向量，得到第一列向量；
通过第二隐层将所述第一列向量转化为第二列向量，所述第二列向量包括的多个列矩阵元分别对应表示多个医疗属性信息。
其中，从用户输入的提问语句中提取得到多个医疗属性关键词可以采用规则引擎方式从用户输入的提问语句中提取。规则引擎是将实体抽取逻辑从代码中剥离出来的一种方法(常用的是Drools)。规则引擎使用预定义的语言将规则写成标准形式，系统运行时采用单独模块驱动解析规则，而不是从代码中读取规则。这增加了规则的可移植性、可维护性，同时由于独立于代码框架，使得代码运行的效率更高。不考虑效率及工程方面的优化，规则引擎可以简单的理解为基于规则的抽取。
进一步地，通过规则引擎方式从所述提问语句中提取医疗属性信息，包括：获取提问语句的起始坐标和结束坐标；基于所述起始坐标和所述结束坐标确定搜寻坐标范围；通过规则引擎方式在所述搜寻坐标范围内提取医疗属性信息。
例如，针对患者血糖的规则引擎定义如下：(1)关键字“血糖”+数字；(2)关键字“学糖”或“雪糖”或“血唐”等+数字；(3)关键字“血糖”+虚词“是”或“为”或“值”等+数字。其中规则(2)针对错别字情况，规则(3)针对在关键词和数字之间包含无实际意义虚词的情况。
可以看出，在本申请实施例中，从用户输入的提问语句中提取得到多个医疗属性关键词，然后将每个医疗属性关键词向量化以及通过第一隐层和第二隐层转化为列向量，列向量的形式表示多个医疗属性信息有利于后续确定多个待确定的提问意图与多个医疗属性信息的相关性。
在本申请的一实现方式中，所述对所述提问语句进行预处理，得到多个待确定的提问意图，包括：
对所述提问语句进行分词处理，得到多个提问关键词；
将每个所述提问关键词嵌入到向量空间，得到多个提问词向量；
通过第三隐层将所述多个提问词向量转化为一维列向量，得到第三列向量；
通过第四隐层将所述第三列向量转化为第四列向量；
将所述第二列向量与所述第四列向量进行拼接，得到第五列向量；
通过第五隐层将所述第五列向量转化为一维行向量，得到第一行向量，所述第一行向 量包括的多个行矩阵元分别对应表示多个待确定的提问意图。
举例说明，例如用户的提问语句例如可以为“我的血糖13，血压150/120，体重80，二甲双胍应该用多大剂量？饮食有什么忌口？”，对该提问语句进行分词处理，得到多个提问关键词“我”、“的”、“血糖13”、“血压150/120”、“体重80”、“二甲双胍”、“应该”、“用”、“多大”、“剂量”、“饮食”、“有”、“什么”、“忌口”。
进一步地，对所述提问语句进行分词处理，得到多个提问关键词，包括：基于所述提问语句的语句构成成分对所述提问语句进行划分，得到多个第一关键词；根据所述语句构成成分对所述第一关键词进行过滤，得到多个提问关键词。
其中，语句构成成分包括以下至少一种：主语、谓语、宾语、定语、状语、补足语、中心语、动语。根据所述语句构成成分对所述第一关键词进行过滤则为删除目标语句构成成分的第一关键词，例如目标语句构成成分可以为主语，“我”、“我们”等，还可以删除如停用词、语气助词，“哦”、“啊”等。
需要说明的是第一隐层和第三隐层的具体构成可以相同，第二隐层和第四隐层的具体构成可以相同。
其中，向量拼接具体实现的方式例如可以如下：第二列向量为(a 1、a 2) T，第四列向量为(b 1、b 2、b 3) T，则拼接后得到的第五列向量可以为(a 1、a 2、b 1、b 2、b 3) T。
可以看出，在本申请实施例中，从用户输入的提问语句中提取得到多个提问关键词，然后将每个提问关键词向量化以及通过第三隐层和第四隐层转化为列向量，最后对向量进行拼接和行向量转化，行向量的形式表示多个待确定的提问意图有利于后续确定多个待确定的提问意图与多个医疗属性信息的相关性。
在本申请的一实现方式中，所述确定所述多个待确定的提问意图与所述多个医疗属性信息的相关性，包括：
将所述第二列向量与所述第一行向量进行点乘运算，得到相关性矩阵，所述相关性矩阵用于表示所述多个待确定的提问意图与所述多个医疗属性信息的相关性，其中，所述相关性矩阵中的矩阵元的取值为1或0，所述1用于表示取值为所述1的矩阵元对应的待确定的提问意图与取值为所述1的矩阵元对应的医疗属性信息相关，所述0用于表示取值为所述0的矩阵元对应的待确定的提问意图与取值为所述1的矩阵元对应的医疗属性信息不相关。
进一步地，将所述第二列向量与所述第一行向量进行点乘运算，得到相关性矩阵，包括：将所述第二列向量与所述第一行向量进行点乘运算，得到第一矩阵；通过sigmoid将所述第一矩阵转化为相关性矩阵。其中，所述sigmoid用于将所述第一矩阵的矩阵元的值转化为0或1。
举例说明，如图2B所示，图2B是本申请实施例提供的一种网络架构图。将“二甲双胍”，特异性生理参数“血糖13”、“血压150/120”、“体重80”嵌入到向量空间，得到多个医疗属性词向量；然后通过如图2B所示的第一隐层将多个医疗属性词向量转化为一维列向量，得到第一列向量；再通过如图2B所示的第二隐层将第一列向量转化为第二列向量；同时， 将多个提问关键词“我”、“的”、“血糖13”、“血压150/120”、“体重80”、“二甲双胍”、“应该”、“用”、“多大”、“剂量”、“饮食”、“有”、“什么”、“忌口”嵌入到向量空间，得到多个提问词向量；通过如图2B所示的第三隐层将多个提问词向量转化为一维列向量，得到第三列向量；然后通过如图2B所示的第四隐层将第三列向量转化为第四列向量；将第二列向量与第四列向量进行拼接，得到第五列向量；通过如图2B所示的第五隐层将第五列向量转化为一维行向量，得到第一行向量；将第二列向量与第一行向量进行点乘运算和通过sigmoid层转化，得到相关性矩阵。
举例说明，提问意图有两个“如何用药”和“如何饮食”，医疗属性信息有两个“血糖13”和“体重80”，如果相关性矩阵为
Figure PCTCN2020099320-appb-000001
则表示“如何用药”与“体重80”相关，“如何饮食”与“血糖13”相关；如果相关性矩阵为
Figure PCTCN2020099320-appb-000002
则表示“如何用药”与“血糖13”相关，“如何饮食”与“体重80”相关；如果相关性矩阵为
Figure PCTCN2020099320-appb-000003
则表示“如何用药”与“血糖13”和“体重80”均相关，“如何饮食”与“体重80”和“血糖13”均相关。
可以看出，在本申请实施例中，将第二列向量与所述第一行向量进行点乘运算，得到相关性矩阵，该相关性矩阵是考虑了多个医疗实体名称和特异性生理参数后得到的，与目标回答语句强相关的医疗实体名称和特异性生理参数权重占比将会更大，比只通过提问语句确定的目标回答语句准确度更高。
在本申请的一实现方式中，所述目标提问意图与所述多个医疗属性信息中的至少一个医疗属性信息相关。
在本申请的一实现方式中，基于所述相关性从所述多个待确定的提问意图中确定目标提问意图，包括：
基于所述相关性矩阵，确定所述多个待确定的提问意图中与所述多个医疗属性信息中每一医疗属性信息相关的占比，得到多个占比；
选取所述多个占比中大于第一预设阈值的占比对应的至少一个待确定的提问意图为目标待确定的提问意图，得到至少一个目标待确定的提问意图；
基于所述至少一个目标待确定的提问意图，确定所述目标提问意图。
其中，上述医疗属性信息可包括：医疗实体名称和特异性生理参数；上述相关性矩阵表示每一待确定的提问意图与每一医疗实体名称以及特异性胜利参数之间的相关性，如此，可基于该相关性矩阵，确定多个待确定的提问意图中每一待确定的提问意图与每一医疗实体名称以及特异性胜利参数在上述相关性矩阵中取值体现为1的个数占比矩阵中所有取值(包括1和0)的占比，如此，可得到与多个医疗属性信息相关的多个占比，并选取大于第一预设阈值的占比对应的至少一个待确定的提问意图为目标待确定的提问意图，占比越大，则表示相关性越强，最后，可将上述至少一个待确定的提问意图确定为上述目标提问意图。
在本申请的一实现方式中，所述目标提问意图与所述多个医疗属性信息中的至少一个医疗属性信息相关。
在本申请的一实现方式中，所述从所述目标提问意图关联的多个待确定的回答语句中，确定所述提问语句的目标回答语句，包括：
从每个所述待确定的回答语句中提取知识侧特征，得到多个知识侧特征；
从所述目标提问意图关联的多个医疗属性信息中，提取得到数据侧特征；
确定所述数据侧特征与每个所述知识侧特征的匹配度，得到多个匹配度；
确定所述多个匹配度中大于或等于预设匹配度的目标匹配度；
确定所述目标匹配度对应的目标知识侧特征；
将所述目标知识侧特征对应的待确定的回答语句作为所述提问语句的目标回答语句。
举例说明，例如用户的提问语句例如可以为“我的血糖13，血压150/120，体重80，应该如何降压？”。从中提取得到知识侧特征(13，150，120，80)，此时判定用户的提问意图为询问服用何种降压药，该提问意图包括两条回答语句：a)年龄不超过40岁，收缩压不高于160，舒张压不高于120，服用格列奈。则该回答语句对应的知识侧特征可以表示为{格列奈：(<＝40,<＝160,<＝120)}；b)年龄超过40岁，收缩压不低于150，舒张压不低于105，服用二甲双胍。则该回答语句对应的知识侧特征可以表示为{二甲双胍：(>40,>＝150,>＝105)}。然后分别确定(13，150，120，80)与(<＝40,<＝160,<＝120)的第二匹配度，(13，150，120，80)与(>40,>＝150,>＝105)的匹配度，将匹配度大的为目标匹配度，则将b)年龄超过40岁，收缩压不低于150，舒张压不低于105，服用二甲双胍。则该回答语句对应的知识侧特征可以表示为{二甲双胍：(>40,>＝150,>＝105)}为目标回答语句。
与所述图2A所示的实施例一致的，请参阅图3，图3是本申请实施例提供的一种问答方法的流程示意图，应用于电子设备，所述方法包括：
