需要说明的是，在不冲突的情况下，本公开中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本公开。
图1示出了可以应用本公开的实施例的信息推送方法或信息推送 装置的示例性系统架构100。
如图1所示，系统架构100可以包括终端设备101、102、103，网络104和服务器105。网络104用以在终端设备101、102、103和服务器105之间提供通信链路的介质。网络104可以包括各种连接类型，例如有线、无线通信链路或者光纤电缆等等。
用户可以使用终端设备101、102、103通过网络104与服务器105交互，以接收或发送消息等。终端设备101、102、103上可以安装有各种客户端应用，例如新闻类应用、购物类应用、视频类应用等等。
终端设备101、102、103可以是硬件，也可以是软件。当终端设备101、102、103为硬件时，可以是具有显示屏并且支持显示信息的各种电子设备，包括但不限于智能手机、平板电脑、电子书阅读器、膝上型便携计算机和台式计算机等等。当终端设备101、102、103为软件时，可以安装在上述所列举的电子设备中。其可以实现成多个软件或软件模块(例如用来提供分布式服务)，也可以实现成单个软件或软件模块。在此不做具体限定。
服务器105可以是提供各种服务的服务器，例如对终端设备101、102、103上的应用提供支持的后台服务器。后台处理服务器可以基于至少一个属性信息和待处理信息集合，通过集合运算，向终端推送信息。
需要说明的是，本公开的实施例所提供的信息推送方法一般由服务器105执行，相应地，信息推送装置一般设置于服务器105中。
需要说明的是，服务器可以是硬件，也可以是软件。当服务器为硬件时，可以实现成多个服务器组成的分布式服务器集群，也可以实现成单个服务器。当服务器为软件时，可以实现成多个软件或软件模块(例如用来提供分布式服务)，也可以实现成单个软件或软件模块。在此不做具体限定。
应该理解，图1中的终端设备、网络和服务器的数目仅仅是示意性的。根据实现需要，可以具有任意数目的终端设备、网络和服务器。
继续参考图2，示出了根据本公开的信息推送方法的一个实施例的流程200。该信息推送方法，包括以下步骤：
步骤201，获取待处理信息集合。
在本实施例中，信息推送方法的执行主体(例如图1所示服务器105)可以首先从本地或通信连接的存储设备中获取待处理信息集合。其中，待处理信息集合中的信息可以是各种各样的信息。待处理信息集合可以是任意的信息集合。待处理信息集合的确定可以由技术人员指定，也可以根据一定的条件进行筛选。例如，可以将某个历史时间段内形成的多个信息组成的集合确定为待处理信息集合。又如，可以将属于预设类别的信息组成的集合确定为待处理信息集合。
步骤202，获取目标用户的至少一个属性信息。
在本实施例中，上述执行主体可以获取目标用户的至少一个属性信息。其中，目标用户可以是任意的用户。目标用户的确定可以由技术人员指定，也可以根据一定的条件筛选得到。例如，执行主体为服务器时，可以将当前发起请求的客户端对应的用户确定为目标用户。根据实际需要，用户的属性包括但不限于：性别、年龄、居住地信息、用户的搜索词、用户的兴趣词等等。属性信息可以是属性的具体取值等相关信息。例如，年龄这个属性对应的属性信息可以是具体的数字(例如25)。又如，性别这个属性对应的属性信息可以是男或女。此外，用户的搜索词、用户的兴趣词可以通过统计得到。作为示例，可以将用户输入或点击的次数超过一定的阈值的词语确定为用户的搜索词或兴趣词。可以理解，具体获取用户的哪些属性信息可以根据需要进行确定。
在本实施例中，作为示例，至少一个属性信息可以预先存储于本地或终端的数据库中，上述执行主体可以通过查询获得至少一个属性信息。此外，上述执行主体可以通过各种方式确定至少一个属性信息。例如，根据实际需要，居住地信息也可以是预先获取的用户输入的居住地信息，也可以是根据用户的登录IP(Internet Protocol，互联网协议)地址等信息确定的居住地信息。
步骤203，基于至少一个属性信息和待处理信息集合，确定目标可推送信息集合和目标不可推送信息集合。
在本实施例中，上述执行主体可以基于至少一个属性信息和待处理信息集合，确定目标可推送信息集合和目标不可推送信息集合。其中，可推送信息集合中的信息可以是可能可以向用户推送的信息。不可推送 信息集合中的信息可以是不可以向用户推送的信息。在此基础上，目标可推送信息集合可以是任意的可推送信息集合。目标可推送信息集合的确定可以由技术人员指定，也可以根据一定的条件筛选得到。类似的，目标不可推送信息集合的确定也可以通过由技术人员指定或者根据条件筛选的方式得到。
在本实施例中，对于至少一个属性信息中的某个属性信息，上述执行主体可以将待处理信息集合中的每个信息在预先建立的对应关系表中进行查询，得到该信息对应的查询结果信息。上述对应关系表中可以预先存储有用户的多个常用的属性信息，以及海量的信息的关键词对应于每个属性信息的查询结果信息。查询结果信息可以用于表征该信息是否为可推送信息或不可推送信息。通过遍历至少一个属性信息中的每个属性信息，可以得到目标可推送信息集合和目标不可推送信息集合。
步骤204，确定目标可推送信息集合和目标不可推送信息集合的差集，以及将差集中的信息推送至目标用户对应的终端。
在本实施例中，上述执行主体可以确定目标可推送信息集合与目标不可推送信息集合的差集。在此基础上，可以将差集中的信息推送至目标用户对应的终端(例如，图1所示的终端设备101、102、103)。实践中，终端可以是硬件，也可以是软件。当终端是硬件是，操作该硬件的用户可以看作与该硬件相对应。当终端是软件时，用户可以通过账号、密码等信息登录该软件。此时，该软件可以看作与用户相对应。
继续参见图3，图3是根据本实施例的信息推送方法的应用场景的一个示意图。在图3的应用场景中，执行主体可以是服务器301。服务器301可以首先获取待处理信息集合302。如图所示，待处理信息集合302包括五个信息。为便于说明，5个信息编号为1-5。目标用户为当前通过笔记本电脑309向服务器301发送信息获取请求的用户308。在此基础上，服务器301可以获取用户308的至少一个属性信息303。在本应用场景下，以获取两个属性信息为例。假设用户308的性别为男，年龄为35岁。两个属性303信息为男、35岁。之后，服务器301可以基于两个属性信息303，将待处理信息集合302中的每个信息的关键字在预设的对应关系表304中进行查询。为便于展示，图中示出的仅为对应关系 表304的部分数据。以性别这个属性为例，可以确定编号为2和4的信息均为可推送信息，而编号为3的信息为不可推送信息。类似的，可以对年龄这个属性，进行确定。在年龄这个属性下，确定的可推送信息为编号为1和编号为3的信息。而确定不可推送的信息为编号为5的信息。通过汇总，可以得到目标可推送信息集合305中包括编号为1、2、3、4的信息。目标不可推送信息集合306中包括编号为3、5的信息。之后，服务器301可以确定目标可推送信息集合305和目标不可推送信息集合306的差集307。本应用场景下，差集307中包括编号为1、2、4的信息。在此基础上，可以将将差集307中的三个信息推送至用户308对应的笔记本电脑309。
本公开的实施例提供的方法，可以首先获取待处理信息集合。之后，可以获取目标用户的至少一个属性信息。在此基础上，基于至少一个属性信息和待处理信息集合，确定目标可推送信息集合和目标不可推送信息集合。最后，确定目标可推送信息集合和目标不可推送信息集合的差集，以及将差集中的信息推送至目标用户对应的终端。由此，可以根据目标用户的属性进行有针对性的信息推送。在此过程中，通过确定目标可推送信息集合与目标不可推送信息集合的差集的方式，确定向目标用户推送的信息。与直接在待处理信息集合中对于至少一个属性信息逐一筛选的方式相比，可以避免对每个属性进行筛选时，将不对该属性进行限定的信息也筛选掉。从而增加向目标用户推送的信息的丰富性和多样性。
进一步参考图4，其示出了信息推送方法的又一个实施例的流程400。该信息推送方法400，包括以下步骤：
步骤401，获取待处理信息集合。
在本实施例中，待处理信息集合中的信息对应至少一个推送条件，推送条件用于对接收信息的终端所对应的用户的属性进行限定。例如，对于一条球赛相关信息。该信息可以设置一个推送条件为：向男性用户推送。
步骤402，获取目标用户的至少一个属性信息。
本实施例中，除步骤401中写明的内容外，步骤401-402的具体实现 及其所带来的技术效果可以参考图2对应的实施例中的步骤201-202，在此不再赘述。
步骤403，基于至少一个属性信息和待处理信息集合，确定目标可推送信息集合和目标不可推送信息集合，包括以下步骤：
步骤4031，从至少一个属性信息中选取属性信息，将当前可推送信息集合和当前不可推送信息集合确定为空集，以及执行以下确定步骤：
步骤4032，从待处理信息集合中确定该属性信息对应的可推送信息集合和不可推送信息集合。
在本实施例中，以至少一个属性信息所指示的属性中包括性别为例。对于待处理信息集合中的某个信息，可以对应推送条件：向男性用户推送。也可以对应推送条件：向女性用户推送。也可以不在性别这个属性下设置推送条件。此时，可以理解为，不对用户的性别进行限定，不论男性用户或女性用户均可以向其推送该信息。可以理解，待处理信息集合中各个信息在同一属性(例如性别)下所对应的推送条件可以不同。
在此基础上，上述执行主体可以确定该属性信息对应的可推送信息集合和不可推送信息集合。其中，可推送信息集合中包括推送条件与该属性信息相符的信息和推送条件不对该属性信息所指示的属性进行限定的信息。例如，男性这个属性信息对应的可推送信息集合中的信息可以为设置了推送条件为：向男性用户推送，这样的信息。此外，还可以是推送条件不对用户的性别进行限定的信息。不可推送信息集合中包括推送条件与该属性信息不相符的信息。例如，男性这个属性信息对应的不可推送信息集合中的信息可以是设置了推送条件为：向女性用户推送，这样的信息。
步骤4033，确定至少一个属性信息中是否存在未被选取过的属性信息，若不存在，将当前可推送信息集合与可推送信息集合的并集确定为目标可推送信息集合，将当前不可推送信息集合与不可推送信息集合的并集确定为目标不可推送信息集合。
步骤4034，若存在，将当前可推送信息集合与可推送信息集合的并集确定为当前可推送信息集合，以及将当前不可推送信息集合与不可推送信息集合的并集确定为当前不可推送信息集合，从至少一个属性信息 集合中选取未被选取过的属性信息，继续执行确定步骤4032-4034。
步骤404，确定目标可推送信息集合和目标不可推送信息集合的差集，以及将差集中的信息推送至目标用户对应的终端。
在本实施例中，确定目标可推送信息集合和目标不可推送信息集合的差集，包括：利用位图索引的方法，确定目标可推送信息集合和目标不可推送信息集合的差集。其中，位图索引(bitmap index)技术利用位(bit)进行运算，可以提高计算速度。具体来说，可以首先将目标可推送信息集合和目标不可推送信息集合中的各个信息进行编码。例如，假设目标可推送信息集合中包括100个信息，那么可以将这100个信息编码为1-100。之后，可以利用至少一个64位的二进制数来表示目标可推送信息集合中的各个信息。例如，对于编码为3的信息，可以将二进制数的第三位设置为1。类似的，可以将100个信息用2个64位的二进制数字表示。在此基础上，可以根据需要，将这两个二进制数字通过一定的方式进行拼接，得到目标可推送信息对应的二进制数字。通过类似的方法，也可以得到目标不可推送信息集合对应的二进制数字。从而可以对目标可推送信息集合和目标不可推送信息集合分别对应的二进制数字按位进行逻辑运算，以得到差集。
在本实施例的一些可选的实现方式中，将当前可推送信息集合与可推送信息集合的并集确定为当前可推送信息集合，包括：利用位图索引的方法，将当前可推送信息集合与可推送信息集合的并集确定为当前可推送信息集合，以及将当前不可推送信息集合与不可推送信息集合的并集确定为当前不可推送信息集合，包括：利用位图索引的方法，将当前不可推送信息集合与不可推送信息集合的并集确定为当前不可推送信息集合。
从图4中可以看出，与图2对应的实施例相比，本实施例的信息推送方法的流程中，通过设置推送条件以及循环执行确定步骤，得到目标可推送信息集合和目标不可推送信息集合。从而使向终端推送的信息更具针对性。此外，通过位图运算进行集合运算，提高了运算速度。
进一步参考图5，作为对上述各图所示方法的实现，本公开提供了一种信息推送装置，该装置与图2所示的方法实施例相对应，该装 置具体可以应用于各种电子设备中。
如图5所示，本实施例的信息推送装置500包括：待处理信息集合获取单元501、属性信息获取单元502、确定单元503和推送单元504。其中，待处理信息集合获取单元501被配置成获取待处理信息集合。属性信息获取单元502被配置成获取目标用户的至少一个属性信息。确定单元503被配置成基于至少一个属性信息和待处理信息集合，确定目标可推送信息集合和目标不可推送信息集合。推送单元504被配置成确定目标可推送信息集合和目标不可推送信息集合的差集，以及将差集中的信息推送至目标用户对应的终端。
在本实施例中，信息推送装置500包括的待处理信息集合获取单元501、属性信息获取单元502、确定单元503和推送单元504的具体实现及其所带来的技术效果可以参考图2对应的实施例的步骤201-204，在此不再赘述。
在本实施例的一些可选的实现方式中，待处理信息集合中的信息对应至少一个推送条件，推送条件用于对接收信息的终端所对应的用户的属性进行限定。
在本实施例的一些可选的实现方式中，确定单元503可以进一步被配置成：从至少一个属性信息中选取属性信息，将当前可推送信息集合和当前不可推送信息集合确定为空集，以及执行以下确定步骤：从待处理信息集合中确定该属性信息对应的可推送信息集合和不可推送信息集合，可推送信息集合中包括推送条件与该属性信息相符的信息和推送条件不对该属性信息所指示的属性进行限定的信息，不可推送信息集合中包括推送条件与该属性信息不相符的信息；确定至少一个属性信息中是否存在未被选取过的属性信息，若不存在，将当前可推送信息集合与可推送信息集合的并集确定为目标可推送信息集合，将当前不可推送信息集合与不可推送信息集合的并集确定为目标不可推送信息集合；若存在，将当前可推送信息集合与可推送信息集合的并集确定为当前可推送信息集合，以及将当前不可推送信息集合与不可推送信息集合的并集确定为当前不可推送信息集合，从至少一个属性信息集合中选取未被选取过的属性信息，继续执行确定步骤。
在本实施例的一些可选的实现方式中，确定单元503可以进一步被配置成：利用位图索引的方法，将当前可推送信息集合与可推送信息集合的并集确定为当前可推送信息集合，以及利用位图索引的方法，将当前不可推送信息集合与不可推送信息集合的并集确定为当前不可推送信息集合。
在本实施例的一些可选的实现方式中，推送单元504可以进一步被配置成：利用位图索引的方法，确定目标可推送信息集合和目标不可推送信息集合的差集。
在本实施例中，可以首先获取待处理信息集合。之后，可以获取目标用户的至少一个属性信息。在此基础上，基于至少一个属性信息和待处理信息集合，确定目标可推送信息集合和目标不可推送信息集合。最后，确定目标可推送信息集合和目标不可推送信息集合的差集，以及将差集中的信息推送至目标用户对应的终端。由此，可以根据目标用户的属性进行有针对性的信息推送。在此过程中，通过确定目标可推送信息集合与目标不可推送信息集合的差集的方式，确定向目标用户推送的信息。与直接在待处理信息集合中对于至少一个属性信息逐一筛选的方式相比，可以避免对每个属性进行筛选时，将不对该属性进行限定的信息也筛选掉。从而增加向目标用户推送的信息的丰富性和多样性。
