所述计算引擎实现程序10可以被分割为:确定模块110、生成模块140和存储模块150。可选的,所述计算引擎实现程序10还可以包括判断模块120和配置模块130。
确定模块110,用于确定组成目标算法链的每个算子。
在本实施例中,所述计算引擎中的各种计算功能通过各条算法链(也称工作流)来实现,而每一条算法链则由若干个算子(也称为插件)组合而成,其中每个算子分别对应一个特定的计算需求。例如定义算子CommonHead对应的计算需求为从页面获取输入数据并存入***通用数据结构MyTupleList,而定义算子Hanlp对应的计算需求为关键词抽取。假设一条实现分词功能的算法链有“从页面获取输入数据并存入***通用数据结构MyTupleList”的计算需求和“关键词抽取”的计算需求,则该实现分词功能的算法链即可由所述CommonHead算子和Hanlp算子组成。针对每一种算法链的算子组合规则,可以由相应的算法号来指示。
一条算法链的形式可以如下所示:
业务号#广告位号#策略号;
算子1简称:算子1名#表号#版本号#权重;
算子2简称:算子2名#表号#版本号#权重。
举例:实现分词功能的算法链如下所示:
10001#024#8024;
Com:CommonHeadV2#-1#-1#1。
其中,上述“业务号#广告位号#策略号”和“10001#024#8024”即为所述算法号。
当开发人员为计算引擎新增计算功能时,需要开发新的算法链,所述新的算法链在本实施例中即被称为目标算法链。此外,开发人员还需要设定所述目标算法链的算子组合规则。确定模块110在接收到开发人员输入的目标算法链的开发请求时,解析出所述目标算法链对应的一个或多个计算需求,并确定每个计算需求对应的算子,从而确定组成目标算法链的每个算子。
可选地,判断模块120,用于判断程序配置文件中是否包含所述组成目标算法链的每个算子,若判断结果为否,则触发所述配置模块130,若判断结果为是,则所述触发所述生成模块140。
具体而言,开发人员可预先针对一些比较普遍的计算需求开发若干通用型算子,并将所述通用型算子预先配置在程序配置文件中。在本实施例中,列举两种通用型算子:
1、算子名称:CommonHead
算子简称:Com
功能:从页面获取输入数据并存入***通用数据结构MyTupleList
格式举例:Com:CommonHead#-1#-1#1;
其中第一个1代表拉取数据的数据表号为1,而-1代表不需要从PG数据库中拉取数据;第二个1代表算法号,而-1代表不需要算法号;最后一个1代表权重。
2、算子名称:Retrieval
算子简称:Retr
功能:从PG库或Redis库拉取数据并存入***通用数据结构MyTupleList
格式举例:Retr:Retrieval#6#1#2_2;
其中6代表从PG库或Redis库中拉取数据的数据表号;1代表算法号,该算法号与该数据存入数据库时的算法号意义一致;2_2中第一个2代表取数方式,第二个2代表取数类型。
具体地,在本实施例中提供一种三层数据存储方式,分别为本地内存缓存、Redis数据存储、PG数据存储。三者的存储容量依次增加,而相应的存储速度依次递减。针对所述三层数据存储方式,对数据库的所述取数方式可以设定为以下五种之一:
1、优先从本地内存缓存中取数,若取成功,则返回该数据,若不成功,再按以下四种方式进行取数;
2、RedisOnly:仅从Redis库取数,本模式适用于数据量较小而对取数速度要求较高的取数需求,前提是数据已存在Redis库;
3、RedisPGSync:先从Redis库取数,如果没有取到,再去PG库取,取到后同步写回Redis库;
4、RedisPGAsync:先从Redis取数,如果没有取到,再去PG库取,取到后异步写回Redis库;
5、PGOnly:仅从PG库取数,本模式适用于数据量大而对取数速度要求相对不高的取数需求。
此外,本实施例还提供一种取数类型的设定,关注的是数据进入PG库的类型,如下:
1 简单类型
2 有序列表
3 无序列表
由此,上述算子Retrieval的格式举例中,对应到以上设定的取数方式和取数类型,所述“2_2”中第一个2代表取数方式为RedisOnly,第二个2代表取数类型为有序列表。
可选地,配置模块130,用于接收按照预定格式输入的目标算子,并将所接收的目标算子配置在程序配置文件中,然后触发所述生成模块140。所述目标算子为不包含在程序配置文件中的组成所述目标算法链的算子。
具体而言,程序配置文件中包含的算子可以为所述的通用型算子,即各种普通需求都有较大可能用到的算子。而所述目标算子则为针对某些计算功能的算法链,所需要的对应特殊需求的算子。当发现要配置目标算法链,仅使用程序配置文件中已有的通用型算子不够时,开发人员需要针对新的计算需求开发新的算子,这种算子可以被统称为功能性算子。所述功能性算子例如:实现分词及相似病例功能需求的切词(关键词抽取)算子Hanlp:KeywordExtraction#-1#-1#1;为实现相似病例功能需求的相似度和排序计算的Sc:BM25New#-1#-1#1和Sort:Heapsort#-1#-1#1算子。功能性算子被配置在程序配置文件中后,可供后续配置算法链时灵活取用。
生成模块140,用于依据所确定的每个算子,以及所设定的目标算法链的算子组合规则,生成相应的算法号。
存储模块150,用于将所述算法号存入数据库。当计算引擎需要执行某一计算功能时,从数据库中获取该计算功能对应的算法号,并根据该算法号从程序配置文件中调用对应的算子组成算法链,执行所述算法链对应的程序,从而实现所述计算功能。
参照图4所示,为本申请计算引擎实现方法较佳实施例的流程图。电子装置1的处理器12执行存储器11中存储的计算引擎实现程序10时实现所述计算引擎实现方法的如下步骤:
步骤S10,确定模块110确定组成目标算法链的每个算子。
步骤S20,判断模块120判断程序配置文件中是否包含所述组成目标算法链的每个算子,若判断结果为否,则执行步骤S30,若判断结果为是,则执行 步骤S40。
步骤S30,配置模块130接收按照预定格式输入的目标算子,并将所接收的目标算子配置在程序配置文件中,然后执行步骤S40。所述目标算子为不包含在程序配置文件中的组成所述目标算法链的算子。
步骤S40,生成模块140依据所确定的每个算子,以及所设定的目标算法链的算子组合规则,生成相应的算法号。
步骤S50,存储模块150将所述算法号存入数据库。所述数据库包括本地内存缓存、Redis库或Postgre SQL库。所述数据库的取数方式包括以下之一:
从本地内存缓存中取数;
仅从Redis库中取数;
先从Redis库中取数,若不成功,则从Postgre SQL库中取数,取到后同步写回Redis库;
先从Redis库中取数,若不成功,则从Postgre SQL库中取数,取到后异步写回Redis库;
仅从Postgre SQL库中取数。
本实施例所述的计算引擎实现方法,在开发和维护计算引擎时以算法链和算子作为实现框架,各个计算功能对应的算法链以算子的形式灵活实现,算子之间以松耦合方式连接,仅对算子间的信息传递格式和内容作规定,而不干涉各个算子的具体实现方法。利用本方法实现新增计算引擎中的计算功能,可以使计算引擎的开发过程更灵活,只需要根据已有的算子配置好算法链,或者在必要的时候开发新的算子,即可实现计算引擎的新功能,具有广泛的普适性和良好的可扩展性,且不需要额外的***代码及数据库开发。
此外,本申请实施例还提出一种计算机可读存储介质,所述计算机可读存储介质可以是硬盘、多媒体卡、SD卡、闪存卡、SMC、只读存储器(ROM)、可擦除可编程只读存储器(EPROM)、便携式紧致盘只读存储器(CD-ROM)、USB存储器等等中的任意一种或者几种的任意组合。所述计算机可读存储介质中包括程序配置文件、数据库、计算引擎实现程序10等,所述计算引擎实现程序10被所述处理器12执行时实现如下操作:
