- the user can send a page request through the display page, the advertisement supporting device receives the page request of the user, and the advertisement in the order advertisement table records all the advertisements that can be broadcasted, taking tens of thousands of advertisements as an example, after the directional retrieval, the remaining number can be left Thousands of ads, and then advertised, the remaining hundreds of ads can form a list of candidate ads, and then accurately predict the click-through rate of all ads in the list of candidates, and then rearrange, for example, according to ECPM rearrangement, the most Excellent advertising, support strategies are usually implemented in the primary election, because if it is implemented in the following links, the ads that may need to be supported have been filtered by the primary election.
- the largest (English name: ToP) N advertisements for broadcasting to the user are selected from the candidate advertisement list, and the supported advertisements and the normally competitive advertisements may be included in the ToP N advertisements.
- ToP N advertisements for broadcasting to the user are selected from the candidate advertisement list, and the supported advertisements and the normally competitive advertisements may be included in the ToP N advertisements.
- a detailed process of the advertisement support provided by the embodiment of the present invention is given as an example. For instructions, see Figure 3. Next, we will introduce the ad selection process for the primary selection.
- CTR calculation is the basis of the process operation.
- the click rate prediction value of each advertisement in the candidate advertisement list of this request is calculated in real time by the model.
- the specific prediction model can use algorithms such as logistic regression and decision tree.
- Judgment of support conditions According to the business rules, it is determined whether the request is to enter the support process. There are a variety of support conditions. For example, there must be at least N advertisements of this type in this request before entering the support process. Otherwise, the normal free competition process, the number of N is determined according to the business scenario, if the type of advertisement is too small, follow-up It may be filtered out, resulting in no requests for this request. Another example is when supporting the app, it is judged that the request must be a WiFi environment, and the support is not supported. The conversion rate in the non-WiFi environment is too low to support.
- This request ranking calculation (the result obtained is represented by rank_this): Calculate the current average ranking of the advertisements of the type of support in this request.
- the ranking may not be the average of all ads of that type, but the average of top M ads, because only the top ad will be exposed in one request, such as a carousel, determining top N based on the carousel rules, non-rotating class The ad is only top1.
- Calculated rankings are also ranked by CTR ranking or ECPM based on business needs.
- the historical support average ranking (the results obtained with rank_avg):
- rank_avg use the historical data statistics to support the average ranking of the type of advertising.
- rank_this uses rank_this to update the ranking summary value and the number of support in the support list, and recalculate the historical support average ranking.
- the embodiment of the invention can calculate the historical support average ranking for each request in real time, thereby ensuring the real-time update of the support type ranking mean.
- the input conditions can be rank_this, rank_avg, total number of requests, number of supported supports, configured support ratio, and whether the request needs to be selected for support. It has the following three parts:
- rank_this is less than rank_avg, the current average ranking of this request is before the historical support average ranking, indicating that the matching of the ad type of the request and the user is higher, then the probability of support is large.
- the method for calculating the probability is not limited.
- rank_avg as the mean value

Description
本申请要求于2016年1月12日提交中国专利局、申请号为201610017753.2、发明名称为“一种信息扶持方法和装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
本发明涉及信息投放技术领域,尤其涉及一种信息投放方法、装置、***和存储介质。
在信息投放的某些时期,常有对某类信息进行扶持的需求。比如信息投放***和电商网站合作,约定信息***需保证20%流量用于投放该电商网站的卖家广告,这样对电商网站上挂售的产品可以作为一种稳定流量,有利于产品运维。又比如,在电商广告逐渐发展较为完善时,探索引入开发平台的应用程序(英文全称:application,英文简称:app)类广告,但初期app类广告主较少,没有广告投放经验,如果没有保护性措施,可能流量和效果波动很大,妨碍广告主的拓展。为创建稳定的app类广告生态,需要对app类广告扶持,在引入充足的app类广告,等到逐渐形成生态时,再完全放开与其他类型广告的自由竞争。
现有的信息投放方案缺乏对扶持需求的灵活控制,因此亟需一种新的投放方案。
发明内容
本发明实施例提供了一种信息投放方法和装置,能够在保证信息投放效果的基础上实现对属于扶持类型的信息的扶持。
第一方面,本发明实施例提供一种信息投放方法,包括:
根据用户发送的页面请求选择候选信息列表,所述候选信息列表包括多个信息;
生成所述候选信息列表中每个信息的排名;
根据所述候选信息列表中每个信息的排名获取所述候选信息列表中指定类型的信息的当前平均排名;
基于所述指定类型的信息的当前平均排名和所述指定类型的信息所对应的预存历史平均排名,确定所述指定类型的信息是否作为指定投放信息。
第二方面,本发明实施例还提供一种信息投放装置,包括:
初选模块,用于根据用户发送的页面请求选择候选信息列表,所述候选信息列表包括多个信息;
排名预测模块,用于生成所述候选信息列表中每个信息的排名;
当前请求计算模块,用于根据所述候选信息列表中每个信息的排名获取所述候选信息列表中指定类型的信息的当前平均排名;
信息投放选择模块,用于基于所述指定类型的信息的当前平均排名和所述指定类型的信息所对应的预存历史平均排名,确定所述指定类型的信息是否作为指定投放信息。
从以上技术方案可以看出,本发明实施例具有以下优点:
在本发明实施例中,首先根据用户发送的页面请求选择候选信息列表,候选信息列表包括:多个信息,然后根据页面请求和配置的预测模型对候选信息列表中每个信息的排名顺序进行预测,从而生成候选信息列表中每个信息的排名,接下来根据候选信息列表中每个信息的排名获取候选信息列表中指定类型的信息的当前平均排名,最后根据指定类型的信息的当前平均排名和指定类型对应的历史扶持平均排名,从指定类型的信息中选择出指定投放信息。本发明实施例中用户发送页面请求之后根据该页面请求对所有信息进行初选,得到和该用户匹配的候选信息列表,从而提高信息投放的用户群体针对性,通过对候选信息列表中所有信息的排序顺序预测可以得到在候选信息列表中属于扶持类型的信息的当前平均排名,最后根据属于扶持类型的信息的当前平均排名和该扶持类型对应的历史扶持平均排名,从属于扶持类型的信息中选择出被扶持信息。由于选择出的被扶持信息是根据当前平均排名和该扶持类型对应的历史扶持平均排名确定的,因此选择出的被扶持信息在候选信息列表的所有信息中是与发送页面请求的用户具有较高匹配度的信息,从而可以匹配用户的兴趣爱
好,保证信息投放效果,同时被扶持信息是从属于扶持类型的信息中选择出的,从而可满足对特定类型的信息扶持需求。
为了更清楚地说明本发明实施例中的技术方案,下面将对实施例描述中所需要使用的附图作简单地介绍,显而易见地,下面描述中的附图仅仅是本发明的一些实施例,对于本领域的技术人员来讲,还可以根据这些附图获得其他的附图。
图1为本发明实施例提供的一种信息投放方法的流程方框示意图;
图2为本发明实施例中信息投放装置的一种实现场景示意图;
图3为本发明实施例中信息投放方法的一种实现场景示意图;
图4-a为本发明实施例提供的一种信息投放装置的组成结构示意图;
图4-b为本发明实施例提供的另一种信息投放装置的组成结构示意图;
图4-c为本发明实施例提供的一种信息投放选择模块的组成结构示意图;
图4-d为本发明实施例提供的另一种信息投放装置的组成结构示意图;以及
图5为本发明实施例提供的信息投放方法应用于服务器的组成结构示意图。
为使得本发明的发明目的、特征、优点能够更加的明显和易懂,下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,下面所描述的实施例仅仅是本发明一部分实施例,而非全部实施例。基于本发明中的实施例,本领域的技术人员所获得的所有其他实施例,都属于本发明保护的范围。
本发明的说明书和权利要求书及上述附图中的术语“包括”和“具有”以及他们的任何变形,意图在于覆盖不排他的包含,以便包含一系列单元的过程、方法、***、产品或设备不必限于那些单元,而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它单元。
针对某类信息的扶持需求,现有的技术方案是配置一定比例的专属流量,该专属流量只允许投放某类受扶持的信息,控制方法通常是根据用户的页面请求按比例随机控制。这种技术方案虽然简单容易实现并且流量稳定,但是存在如下的问题:通过随机产生的流量中有些用户对受扶持的这类信息不感兴趣,但是随机控制可能刚好投放了该类信息,也有部分用户对受扶持的这类信息感兴趣,但在随机控制时可能恰好没有投放到该类信息。因此,这样的方案采用的信息扶持策略虽然能控制流量占比,但信息投放效果不佳。
本发明实施例提供了信息投放方法和装置,能够在保证信息投放效果的基础上实现对属于扶持类型的信息的扶持。
本发明信息投放方法的一个实施例,具体可以应用于对特定类型的信息扶持场景中,具体的,该信息可以为广告,另外本发明实施例中所述的信息也可以是需要扶持的资源、内容、数据等形式,具体不做限定。请参阅图1所示,本发明一个实施例提供的信息投放方法,可以包括步骤101至步骤104。
在步骤101中,根据用户发送的页面请求选择候选信息列表,候选信息列表包括多个信息。
在本发明实施例中,当用户访问页面时,用户可以发送页面请求,本发明实施例提供的信息投放装置可以接收到用户发送的页面请求,从用户发送的页面请求可以获取到该用户的相关信息,该用户的相关信息可以用于确定出该用户对哪些类型的信息感兴趣或者确定出该用户对哪方面的信息有观看意愿,例如确定用户对哪方面的广告有观看意愿。具体的,用户发送的页面请求可以携带用户操作终端的设备信息、访问上下文信息和用户属性信息,则信息投放装置可以从该页面请求中获取到上述信息内容,信息投放装置根据该页面请求可以对所有待定播出的信息进行初选,得到和该用户匹配的候选信息列表,该候选信息列表中的所有信息是信息投放装置进行过初选之后得到的信息,候选信息列表中的所有信息都是可能满足用户兴趣爱好需要的信息类型,根据页面请求进行信息初选可以提高信息投放的用户群体针对性,这与现有技术中采用随机播放而无法保证信息效果的方式是完全不同的实现方式,例如本发明实施例可以根据页面请求进行广告初选可以提高广告投放的用户群体针对性,这与现有技术中采用随机播放而无法保证广告效果的方式是完全不同的实现方式。
在本发明的一些实施例中,接收到用户发送的页面请求之后,在生成候选信息列表时还可以根据该用户的页面请求以及信息主投放信息的投放条件对信息的面向对象进行定向检索,以减少和用户不匹配的信息被播出导致的信息投放效果差的问题。举例说明如下,以信息具体为广告为例,广告主制作的广告为母婴类用品,广告主确定的投放对象为25至40岁的女性,则可以按照广告主的需求来对广告的面向对象进行定向检索,若发送页面请求的用户为男性,则可以通过该定向检索,确定母婴类用品的广告不向男性用户投放,该母婴类用品的广告不需要包括在候选广告列表中。
需要说明的是,在本发明实施例中,候选信息列表是针对发送页面请求的用户来制定的,该候选信息列表中包括有多个信息,这些信息可以属于同一个信息类型,也可以属于不同的信息类型。并且在候选信息列表中包括的所有信息中有的信息可以属于指定类型的信息,例如需要扶持类型的信息。由背景技术可知,例如,app类型广告可以是需要扶持类型的广告,其它特定类型的广告也可以是需要扶持类型的广告。本发明实施例中属于扶持类型的信息是包括在候选信息列表中,但是属于扶持类型的信息是否确定被扶持还可以结合后续实施例中描述的信息投放方法来确定。
在步骤102中,按照预定规则对候选信息列表中的多个信息进行排序,生成候选信息列表中每个信息的排名。
在本发明的一些实施例中,可以根据页面请求和配置的预测模型对候选信息列表中每个信息的排名顺序进行预测,从而生成候选信息列表中每个信息的排名。
在本发明实施例中,通过初选方式确定了候选信息列表,然后根据用户发送的页面请求和配置的预测模型预测候选信息列表中所有信息的排名顺序,以候选信息列表中包括M(M为非零自然数)个信息,那么就需要对第1个信息、第2个信息、…、第M个信息在候选信息列表中的排名顺序分别进行预测,从而生成候选信息列表中每个信息的排名。其中每个信息的排名确定了在候选信息列表中每个信息的排名先后,通过对候选信息列表中所有信息的排名预测,可以预测中候选信息列表中每个信息与发送页面请求的用户之间的匹配程度,在候选信息列表中排名越靠前的信息与发送页面请求的用户越匹配。
需要说明的是,在实际应用中,候选信息列表中每个信息的排名预测可以根据用户的页面请求和配置的预测模型来确定。例如,信息投放装置可以根据用户、上下文场景、信息三方面因素预测各个信息的排名顺序,具体使用到的预测模型可以是逻辑回归算法,也可以是决策树算法等具体的预测算法实现的模型。
在本发明的一些实施例中,步骤102根据页面请求和配置的预测模型对候选信息列表中每个信息的排名顺序进行预测,从而生成候选信息列表中每个信息的排名,具体可以包括如下步骤:
A1、根据页面请求和预置的预测模型获取候选信息列表中每个信息的点击率预测值,并根据每个信息的点击率预测值获取候选信息列表中每个信息的排名。
其中,信息投放装置可以根据页面请求和预置的预测模型对候选信息列表中所有信息的点击率(英文全称:Click Through Rate,英文简称:CTR)进行预测,CTR可以反映用户对信息(例如广告)的喜好,根据用户的页面请求和预测模型可以预测候选信息列表中每个信息的CTR,从而生成每个信息的CTR预测值,根据CTR预测值的大小可以作为候选信息列表中每个信息的排名依据,从而得到候选信息列表中每个信息的排名。需要说明的是,计算每个信息的点击率预测值可以作为信息排名的一种依据,但是本发明实施例中并不局限于使用点击率预测值这种方式,在实际应用中,还可以采用其它方式作为信息排名的依据。例如,步骤A1中的根据每个信息的点击率预测值获取候选信息列表中每个信息的排名,可以包括步骤A11至步骤A12。
在步骤A11中,根据每个信息的点击率预测值获取每个信息的收益预测值;
在步骤A12中,对候选信息列表中所有信息的收益预测值按照取值大小顺序依次排列,得到候选信息列表中每个信息的排名。
其中,步骤A11中,得到信息的点击率预测值之后,可以根据信息的每次点击收益(英文全称:Cost Per Click,英文简称:CPC)计算出期望的千次曝光收益(英文全称:Expect Cost Per Mile,英文简称:ECPM),即ECPM=CTR*CPC。计算出每个信息的收益预测值之后,可以对候选信息列表
中所有信息的收益预测值按照取值大小顺序依次排列,得到候选信息列表中每个信息的排名。
在本发明的一些实施例中,所述指定类型的信息可以是属于扶持类型的信息,也即预先确定需要受扶持类型的信息。在本发明的这些实施例中,步骤102根据页面请求和配置的预测模型对候选信息列表中每个信息的排名顺序进行预测,从而生成候选信息列表中每个信息的排名之后,本发明实施例提供的信息投放方法还可以包括:
判断候选信息列表中属于扶持类型的信息是否满足预置条件,若属于扶持类型的信息满足所述条件,触发如下步骤103执行:根据候选信息列表中每个信息的排名获取候选信息列表中指定类型的信息的当前平均排名。
也就是说,在生成候选信息列表中每个信息的排名之后,可以对候选信息列表中属于扶持类型的信息进行分析,结合预置的扶持条件确定是否需要对属于扶持类型的信息,若需要对属于扶持类型的信息进行扶持,则再触发执行后续步骤103,并在步骤103执行之后可以执行步骤104。若不需要对属于扶持类型的信息进行扶持,则无需执行后续的信息扶持流程,可以结束流程,按照候选信息列表中所有信息进行公平竞争,最后确定出向用户播出的信息。
应该理解,可以根据需要设定不同的扶持条件,并且本发明实施例在此方面不受限制。在实际应用中,扶持条件可以根据业务规则来确定,举例说明如下,若属于扶持类型的信息在候选信息列表中的排名位于整个列表的最后20%,则说明属于扶持类型的信息与用户的匹配程度较低,可以不对属于扶持类型的信息进行扶持,以避免用户对信息满意度的下降。另外扶持条件可以设置为用户发送请求处于无线局域网(英文全称:Wireless Fidelity,英文简称:WiFi)环境,则根据用户发送的页面请求确定用户不是使用WiFi时可以不进行信息扶持,以避免给用户带来的流量损耗。
在步骤103中,根据候选信息列表中每个信息的排名获取候选信息列表中属于指定类型的信息的当前平均排名。
在本发明实施例中,通过前述步骤102中对候选信息列表中所有信息的排名预测,可以生成候选信息列表中每个信息的排名,接下来根据候选信息列表中每个信息的排名可以计算出在候选信息列表中指定类型的信息的当前平均
排名。例如,以指定类型为需要扶持类型为例,以需要扶持类型为app类型为例,以信息具体为广告为例,属于扶持类型的广告可以是app类型广告,计算app类型广告在候选广告列表中的当前平均排名,若app类型广告1在候选广告列表中排名为t1,若app类型广告2在候选广告列表中排名为t2,则app类型广告的当前平均排名为(t1+t2)/2。可以理解的是,若属于扶持类型的广告为1个,则该广告在候选广告列表中的排名就是属于扶持类型的广告的当前平均排名。可以理解,虽然上面示例性地描述了计算排名的方式,但是本发明在此方面不受限制,可以根据需要选择现有或者后续开发的算法。
在步骤104中,根据指定类型的信息的当前平均排名和指定类型的信息所对应的历史平均排名,从指定类型的信息中选择出指定投放信息。
根据本发明的一些实施例,所述指定投放信息是以受扶持形式投放的信息,所述历史平均排名为历史扶持平均排名。
在本发明实施例中,获取到指定类型的信息的当前平均排名之后,通过该当前平均排名可以确定指定类型的信息与用户的匹配程度,结合该扶持类型对应的历史平均排名,可以判断指定类型的信息的当前平均排名和指定类型对应的历史平均排名,从而得到当前平均排名与历史平均排名的关系,依据这两者的关系可以从指定类型的信息中选择出指定投放信息。例如,对于指定类型的信息是确定需要扶持的信息,历史平均排名是针对需要扶持的信息类型通过历史数据累计得出的一个排名均值,该历史扶持平均排名可以用于衡量当前的指定类型的信息是否应该被扶持的参照量。在实际应用中,对于当前平均排名和历史扶持平均排名的分析可以有多种方式,从而依据两者的关系确定属于扶持类型的某个信息或者某些信息是否作为被扶持信息。举例说明如下,若当前平均排名小于历史扶持平均排名,则说明属于扶持类型的信息与用户的匹配程度高,可以将属于扶持类型的信息作为被扶持信息。不限定的是,根据属于扶持类型的信息的当前平均排名和扶持类型对应的历史扶持平均排名在选择被扶持信息时可以不局限于上述方式,还可以结合其他的参量因子用于确定被扶持信息。
在本发明的一些实施例中,步骤104根据指定类型的信息的当前平均排名和扶持类型对应的历史平均排名,从指定类型的信息中选择出指定投放信息,
具体可以包括步骤C1至步骤C4。
在步骤C1中,根据属于扶持类型的信息的当前平均排名和扶持类型对应的历史扶持平均排名计算出属于扶持类型的信息的优选概率;
在步骤C2中,根据属于扶持类型的信息的已选择扶持数、用户发送的总请求数、预置的扶持比例计算出当前扶持满足度;
在步骤C3中,根据属于扶持类型的信息的优选概率和当前扶持满足度计算属于扶持类型的信息的扶持概率;
在步骤C4中,根据属于扶持类型的信息的扶持概率确定属于扶持类型的信息是否被选中输出,将被选中输出的信息作为被扶持信息。
其中,步骤C1至步骤C4给出一种具体的选择被扶持信息的实现方式,这种实现方式中需要先计算出属于扶持类型的信息的优选概率,优选概率指的是信息被选中进行扶持的选中概率,通过属于扶持类型的信息的当前平均排名和扶持类型对应的历史扶持平均排名可以计算出该优选概率。例如,通过正态分布计算概率法可以计算出属于扶持类型的信息的优选概率,即可以计算属于扶持类型的信息的当前平均排名和扶持类型对应的历史扶持平均排名之间的标准正态分布,通过标准正态分布确定优选概率的取值。可以理解的是,上述举例只是本发明实施例中的一种可实现方式,不能作为对本发明的限定。
在步骤C2中,属于扶持类型的信息的已选择扶持数指的是在当前的请求情况下已经被扶持的信息个数,用户发送的总请求数是指信息投放装置已经接收到的页面请求的个数,扶持比例属于产品规则,是可以预先配置理决定,是信息投放装置的外部参数,信息投放装置具备该扶持功能。计算出的当前扶持满足度是指在本次请求中信息扶持的满足程度,若当前扶持满足度取值过大,则说明需要减少对属于扶持类型的信息的扶持,若当前扶持满足度取值过小,则说明需要加大对属于扶持类型的信息的扶持。在实际应用中,根据属于扶持类型的信息的已选择扶持数、用户发送的总请求数、预置的扶持比例计算出当前扶持满足度可以有多种实现。举例说明如下:先根据属于扶持类型的信息的已选择扶持数、用户发送的总请求数计算出当前已扶持百分比,再根据当前已扶持百分比和预置的扶持比例进行数值比较,得到当前扶持满足度。
在步骤C3中,得到属于扶持类型的信息的优选概率和当前扶持满足度之
后,根据属于扶持类型的信息的优选概率和当前扶持满足度可以确定属于扶持类型的信息的扶持概率,扶持概率指的是属于扶持类型的信息可以进行扶持的概率参量。举例说明,可以将属于扶持类型的信息的优选概率除以当前扶持满足度得到属于扶持类型的信息的扶持概率。需要说明的是,上述实现情况只是举例,在实际应用中,还可以采用其它的方式来计算属于扶持类型的信息的扶持概率,例如,将属于扶持类型的信息的优选概率除以当前扶持满足度,再对相除之后得到的结果按照扶持因子进行修正从而得到属于扶持类型的信息的扶持概率。扶持因子可以是一个比例校正参量,具体实现方式不做限定。在得到属于扶持类型的信息的扶持概率之后,可以根据属于扶持类型的信息的扶持概率确定属于扶持类型的信息是否被选中输出,将被选中输出的信息作为被扶持信息,即可以计算出的扶持概率来确定被扶持信息,从而保证扶持流量的稳定性。
在本发明的一些实施例中,步骤104根据指定类型的信息的当前平均排名和扶持类型对应的历史平均排名,从指定类型的信息中选择出指定投放信息之后,本发明实施例提供的信息投放方法还可以包括如下步骤:
根据属于扶持类型的信息的当前平均排名对该扶持类型对应的历史平均排名进行更新,并保存更新后的扶持类型对应的历史平均排名。
特别地,所述历史平均排名可以是历史扶持平均排名。扶持类型对应的历史扶持平均排名可以是一个动态更新的历史排名均值,在当前的请求已经确定被扶持信息之后,可以对该历史扶持平均排名进行实时更新,从而为下一个请求提供更新后的扶持类型对应的历史扶持平均排名,保证历史扶持平均排名是一个实时的最新均值,以保证扶持流量的均衡。
通过以上实施例对本发明实施例的描述可知,首先根据用户发送的页面请求选择候选信息列表,候选信息列表包括:多个信息,然后根据页面请求和配置的预测模型对候选信息列表中每个信息的排名顺序进行预测,从而生成候选信息列表中每个信息的排名,接下来根据候选信息列表中每个信息的排名获取候选信息列表中属于扶持类型的信息的当前平均排名,最后根据属于扶持类型的信息的当前平均排名和扶持类型对应的历史扶持平均排名,从属于扶持类型的信息中选择出被扶持信息。本发明实施例中用户发送页面请求之后根据该页
面请求对所有信息进行初选,得到和该用户匹配的候选信息列表,从而提高信息投放的用户群体针对性,通过对候选信息列表中所有信息的排序顺序预测可以得到在候选信息列表中属于扶持类型的信息的当前平均排名,最后根据属于扶持类型的信息的当前平均排名和该扶持类型对应的历史扶持平均排名,从属于扶持类型的信息中选择出被扶持信息。由于选择出的被扶持信息是根据当前平均排名和该扶持类型对应的历史扶持平均排名确定的,因此选择出的被扶持信息在候选信息列表的所有信息中是与发送页面请求的用户具有较高匹配度的信息,从而可以匹配用户的兴趣爱好,保证信息投放效果,同时被扶持信息是从属于扶持类型的信息中选择出的,从而可满足对特定类型的信息扶持需求。
为便于更好的理解和实施本发明实施例的上述方案,下面举例相应的应用场景来进行具体说明。接下来以指定的需要扶持的信息具体为广告为例进行说明,请参阅图2和图3所示,图2为本发明实施例中信息投放装置的一种实现场景示意图,图3为本发明实施例中信息投放方法的一种实现场景示意图。本发明实施例介绍一种实时计算的择优扶持方案,实时判定每次请求中待定广告的排名与已选扶持广告平均排名比较,候选广告排名靠前,则选入扶持概率越高,否则选入扶持概率低。该方案不仅保证扶持数量符合需求,而且保证扶持质量优质,提升广告投放效果。如图2所示,对本发明实施例提供的广告扶持装置的一种实现场景进行说明,广告扶持的流程中通常包含:定向检索、广告初选(上万个广告中选择较优的几百个广告)、广告精准预测和重排几个环节,接下来分别进行详细说明。用户可以通过展示页面下发页面请求,广告扶持装置接收到该用户的页面请求,订单广告表中记录了所有可以播出的广告,以几万条广告为例,经过定向检索之后,可以剩余几千条广告,然后进行广告初选,可以剩余几百条广告组成候选广告列表,然后对候选广告列表中所有广告的点击率进行精准预测,最后再经过重排,例如根据ECPM重排,投放最优广告,扶持策略通常会在初选就实施,因为如果在后面的环节实施的话,可能需要扶持的广告已经被初选过滤。从候选广告列表中选择出用于向用户播出的最大(英文名称:ToP)N条广告,在ToP N条广告中可以包括被扶持的广告以及正常竞争的广告。接下来对本发明实施例提供的广告扶持的详细流程进行举例
说明,请参阅如图3所示。接下来介绍初选中的广告择优流程。
1、CTR计算:CTR计算是流程运行的基础,通过模型实时计算本次请求的候选广告列表中每个广告的点击率预测值,具体预测模型可使用逻辑回归、决策树等算法。
2、扶持条件判断:根据业务规则判定该次请求是否要进入扶持流程。扶持条件可以有多种,比如,本次请求中至少要有N个该类型广告,才进入扶持流程,否则正常自由竞争流程,N的个数根据业务场景决定,如果该类型广告太少,后续可能会被过滤完,导致本次请求无广告可展示。又如对app广告扶持时,判断本次请求必须是WiFi环境,才进行扶持,非WiFi环境下的转化率太低,不能扶持。
3、本次请求排名计算(得到的结果用rank_this表示):计算本次请求中需扶持类型的广告的当前平均排名。该排名可以不是所有该类型所有广告的均值,而是top M个广告的均值,因为一次请求只有top广告会被曝光,例如轮播类广告,根据轮播页面规则确定top N,非轮播类广告只有top1。计算排名也根据业务需求按CTR排名或ECPM排名。
4、历史扶持平均排名(得到的结果用rank_avg表示):在初始化运行时,使用历史数据统计需扶持类型广告的平均排名。当新来一条符合扶持的流量时,使用rank_this更新扶持列表的排名汇总值和扶持个数,重新计算出历史扶持平均排名。本发明实施例可以对每条请求实时计算历史扶持平均排名,从而保证了扶持类型排名均值的实时更新。
5、扶持计算:其中输入条件可以是rank_this、rank_avg、总请求数、已选择扶持数、配置的扶持比例,输出本次请求是否需要被选中扶持。有如下3部分组成:
1)通过rank_this和rank_avg,计算优选概率。
如果rank_this小于rank_avg,本次请求的当前平均排名在历史扶持平均排名之前,说明本次请求的属于扶持类型的广告与用户的匹配度更高,则选择扶持概率大。具体计算概率的方法不限,接下来举例说明,一种正态分布计算概率法。以rank_avg为均值,通过扶持列表实时更新方差σ,转化成标准正态分布u=(rank_avg–rank_this)/σ,通过正态分布概率映射表,由u查询获取
覆盖面积a。选择2倍方差内数据可信,优选概率p_match计算方法如下:
p_match=a -2<z<2时;
p_match=1 z>=2;
p_match=0 z<=-2。
p_match反映了本次请求用户对扶持类型广告的喜好度。
2)通过当前扶持数、总请求数、配置的扶持比例,计算当前扶持满足度。
p_now=当前扶持数/总请求数;
p_need=扶持比例;
p_satisfy=p_now/p_need。
如果p_satisfy>1,说明扶持过多,需要减少扶持,反之说明扶持力度太小,需要加大扶持。
3)计算扶持概率p_select=p_match/p_satisfy。当前请求匹配度越高,当前满足度越低,则被选中的概率越大。可以设置p_select大于1,则被选中,小于1,则不选。也可以再设计个p_select的概率函数,通过概率计算是否被选中。满足上述扶持概率的流量,最后流入专属扶持流量。整个流程是个实时更新的闭环,每条数据都会修正当前系数,影响下一条请求被选中的概率,扶持占比实时调整,围绕着配置扶持比例波动,在数量上保证了扶持流量的稳定性。进入扶持的流量是该类广告排名靠前的用户,也就说是对该类广告点击意愿高的用户,在质量上保证了投放匹配度更高的广告。从而达到了在保证扶持比例的情况下,择优扶持的策略。
本发明实施例中,实时计算调整用户排名,扶持流量稳定。基于用户对广告的点击率预测基础上,动态选择匹配度高的流量扶持某类广告,扶持保量的基础上,可以明显提升点击率效果。
