本申请提供的产品信息推送方法,可以应用于如图1所示的应用环境中。终端102与服务器104通过网络进行通信。服务器104接收终端102发送的产品信息获取请求,从产品信息获取请求中提取产品实体名称,根据产品实体名称以及预设的词向量数据库,确定产品实体名称的词向量,根据产品实体名称的词向量,生成产品信息获取请求的目标向量,计算目标向量与预设的知识图谱库中各三元组的向量之间的向量距离,三元组包括两个实体名称以及两个实体名称之间的实体关系,当知识图谱库中存在目标三元组的向量时,将产品实体名称与目标三元组中的两个实体名称进行匹配,确定与产品实体名称匹配的实体名称,并根据与产品实体名称匹配的实体名称所在的实体关系,确定对应的产品信息,并将产品信息推送至产品信息获取请求的发送方的终端102,目标三元组的向量为与目标向量的向量距离在预设的向量距离阈值范围内的向量,当知识图谱库中不存在目标三元组的向量时,根据产品信息获取请求生成服务提示,并将服务提示发送至客服终端,将客服终端反馈的产品信息推送至产品信息获取请求的发送方的终端102。终端102可以但不限于是各种个人计算机、笔记本电脑、智能手机、平板电脑和便携式可穿戴设备,服务器104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。
在其中一个实施例中,如图2所示,提供了一种产品信息推送方法,以该方法应用于图1中的服务器为例进行说明,包括以下步骤:
S202:接收产品信息获取请求,从产品信息获取请求中提取产品实体名称。
产品信息获取请求中包括与用户想要获取的产品信息对应的产品实体名称以及产品属性,产品实体名称指的是产品名称,产品属性包括容量以及颜色等。服务器接收产品信息获取请求,确定产品信息获取请求的数据类型,数据类型包括语音数据和文字数据,当数据类型为语音数据时,将语音数据转换为文字数据,当数据类型为文字数据时,不需要进行转换,对文字数据进行句法分析,确定文字数据的句法结构,将文字数据拆分为多个词语,确定拆分后的多个词语的词性,根据句法结构以及拆分后的多个词语的词性确定产品实体名称。
S204:根据产品实体名称以及预设的词向量数据库,确定产品实体名称的词向量,根据产品实体名称的词向量,生成产品信息获取请求的目标向量。
服务器根据产品实体名称遍历预设的词向量数据库,确定产品实体名称的词向量,根据预设的产品属性词库提取产品信息获取请求中的多个词语,根据预设的词向量数据库,确定提取出的各词语的词向量,根据提取出的各词语的词向量以及产品实体名称的词向量,生成产品信息获取请求的目标向量。在词向量数据库中存储了各个词语以及与各词语对应的词向量,产品属性词库中存储了用于表示产品属性的词语,词向量数据库和产品属性词库都可按照需要自行设置。
S206:计算目标向量与预设的知识图谱库中各三元组的向量之间的向量距离,三元组包括两个实体名称以及两个实体名称之间的实体关系。
知识图谱是一种数据结构,把世界上的知识组织成实体与实体之间的关系,实体与实体之间通过实体关系联系在一起。三元组指的是知识图谱中的两个实体以及两个实体之间的实体关系的组合。在本实施例中,预设的知识图谱库中的各三元组中包括两个实体名称以及两个实体名称之间的实体关系,两个实体名称分别与产品实体名称以及产品信息对应,实体关系与产品属性相对应。服务器获取预设的知识图谱库中各三元组的向量,各三元组的向量包括实体名称向量以及实体关系向量,获取目标向量中的产品实体名称向量以及产品属性向量,计算产品实体名称向量与各三元组的向量中的实体名称向量之间的第一词向量距离,计算产品属性向量与各三元组的向量中的实体关系向量之间的第二词向量距离,根据第一词向量距离和第二词向量距离,计算目标向量与各三元组的向量之间的向量距离。
S208:当知识图谱库中存在目标三元组的向量时,将产品实体名称与目标三元组中的两个实体名称进行匹配,确定与产品实体名称匹配的实体名称,并根据与产品实体名称匹配的实体名称所在的实体关系,确定对应的产品信息,并将产品信息推送至产品信息获取请求的发送方,目标三元组的向量为与目标向量的向量距离在预设的向量距离阈值范围内的向量。
向量距离阈值可按照需要自行设置。当知识图谱库中存在目标三元组的向量时,将产品实体名称与目标三元组中的两个实体名称进行匹配,确定与产品实体名称匹配的实体名称,在目标三元组中包括两个实体名称,其中一个实体名称与产品实体名称相对应,另一个实体名称与产品信息相对应,并根据与产品实体名称匹配的实体名称所在的实体关系以及目标三元组的实体关系,确定对应的产品信息,并将产品信息推送至产品信息获取请求的发送方,目标三元组的实体关系具体可以为产品实体名称与产品信息之间的对应关系。进一步的,实体关系可以为产品属性。
S210:当知识图谱库中不存在目标三元组的向量时,根据产品信息获取请求生成服务提示,并将服务提示发送至客服终端,将客服终端反馈的产品信息推送至产品信息获取请求的发送方。
当知识图谱库中不存在目标三元组的向量时,就无法利用知识图谱库实现对产品信息获取请求的发送方的准确反馈,此时服务器可根据产品信息获取请求生成服务提示,并将服务提示发送至客服终端,将客服终端反馈的产品信息推送至产品信息获取请求的发送方,服务提示用于提示使用客服终端的客服人员反馈产品信息。
上述产品信息推送方法,通过预设知识图谱库存储三元组的向量,在接收到产品信息获取请求时,将产品信息获取请求表述为对应的目标向量,并通过目标向量与各三元组的向量之间的向量距离匹配出对应的目标三元组,当匹配结果为存在目标三元组时,可基于目标三元组确定对应的产品信息并进行推送,当匹配结果为不存在目标三元组时,通过向客服终端发送服务提示,可以从客服终端获得反馈的产品信息并进行推送。这种推送方式,通过存储三元组的向量的知识图谱,并用向量匹配的方式匹配出对应的产品信息进行推 送,无需用关键字进行全面检索,提高了产品信息推送的效率,在知识图谱中没有匹配的目标三元组的向量的情况下,还从客服终端获得反馈的产品信息并进行推送,进一步提高了产品信息推送的准确性。
