Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.
Fig. 1 is a schematic flow chart of a data processing method according to an embodiment of the present invention, as shown in fig. 1, the method includes:
101. and receiving a processing request sent by a request device, wherein the processing request comprises the identification of the target website.
Specifically, the website may be a microblog website, such as a green microblog, a vacation microblog, or the like, and the identification of the website may be identified by a Service Profile Identifier (spID for short).
102. According to the collected historical original data, the average number of information corresponding to each type issued in the target website by the user in a preset target time range is obtained, and the historical original data comprises the information issued in each website by each user.
In practical application, the historical raw data can be obtained by designing a data structure and storing and compressing the data structure by using a distributed architecture on the basis of large-scale social network information. Specifically, the social network information may include a posting time, a website, a type of posted information, an identification of a user, and the like. The types may include various situations, such as originality, forwarding, commenting, sharing, and the like.
Further, in the data processing process of this embodiment, in order to be able to quickly read the historical raw data, the information in the social network information may be concatenated, and a "#" separation is used between each piece of information. Specifically, the user identifier may be a user code (usercode) identifier, the type identifier may be an assetType identifier, and the release time identifier may be a date identifier. For example, the last stored historical raw data may be in the form of: the post time # website identifies the # type identifies the # user's identification, namely date # spID # assetType # usercode. For example, if the user of user a issues information of type D at website C at time B, the historical raw data corresponding to the information may be B # C # D # a.
Further, in order to save storage space and transmission bandwidth, data obtained after splicing can be compressed before storage, and specifically, a Lempel-Ziv-oberhimer (LZO) compression algorithm with a high compression ratio and a high transmission speed can be used for compression.
Specifically, in this embodiment, the average number of information may be the number of information in a unit time length, and accordingly, 102 may include:
obtaining the quantity of information corresponding to each type issued in the target website by the user within the target time range according to the historical original data;
and dividing the number of the information corresponding to each type by the duration corresponding to the target time range to obtain the average number of the information corresponding to each type published in the target website by the user in the target time range.
And the duration corresponding to the target time range is the number of unit durations in the target time range. Specifically, the unit time length may be preset. It should be noted that, for different unit durations, the average number of calculated information may also be different, and for example, assuming that the number of certain types of information published in a website by a user in the last week is 70, if a day is taken as the unit duration, the duration corresponding to the target time range is 7/1=7, and the average number of corresponding information is 70/7= 10; if the unit duration is one week directly, the duration corresponding to the target time range is 7/7=1, and the average number of the corresponding pieces of information is 70/1= 70.
More specifically, in practical applications, the specific process of obtaining the amount of the information corresponding to each type published in the target website by the user in the target time range may include:
according to a preset target time range, obtaining information corresponding to each type issued in each website by each user in the target time range, wherein the data format is as follows: spiD # assetType # usercode;
and performing dimensionality reduction processing on the data to obtain the quantity of information corresponding to each type issued in the target website by the target user in the target time range, wherein the data format is spID # assetType # user code num.
Specifically, dimension reduction processing may be performed using a format (key, value), where the value is the number of times the key value appears. Furthermore, in order to more intuitively understand the scheme of the present embodiment, the following example is used for illustration, and it should be noted that the following example is only a specific embodiment, and does not limit other embodiments of the present embodiment.
Assuming that the number of the information of type D issued by the user a in the website C in the target time range needs to be counted currently, the information corresponding to each type issued by each user in each website in the target time range may be queried by using the C # D # a as a key value. Specifically, through the above operation, the format of the output data is C # D # a [1,1, … ], where a "1" is noted in [1,1, … ] every time the key value appears. After the query is finished, counting the number of '1', namely summing up the times of occurrence of the key value, to obtain a value, namely the number of the information of the type D issued by the user A in the website C within the target time range. Further, the output result data is C # D # a num, where num is a value.
103. And calculating the product of the average number of the information corresponding to each type and a preset weight corresponding to the type, wherein the sum of the weights corresponding to the types is 1.
Specifically, there is a difference in contribution of different types of information to the user liveness, for example, in the types of originality, forwarding and comment, the information of the original type can reflect the user liveness better. Therefore, the weights corresponding to different types can be set according to the influence of different types on the activity of the user. For example, assume that the types include an original type, a forwarding type, and a comment type, the weight corresponding to the original type is 0.7, the weight corresponding to the forwarding type is 0.2, and the weight corresponding to the comment type is 0.1. Correspondingly, assuming that the average number of the information corresponding to the original, forwarded and comment types published in the target website by the user in the target time range is 30, 20 and 10, respectively, the product corresponding to the original type is 0.7 × 30=21, the product corresponding to the forwarded type is 0.2 × 20=4, and the product corresponding to the comment type is 0.1 × 10= 1.
104. And calculating the sum of products corresponding to each type to obtain the user activity of the user relative to the target website within the target time range.
Specifically, in the above example, the user activity of the user with respect to the target website in the target time range is 21+4+1= 26.
105. Sending a processing result to the requesting device, the processing result including the user activity.

Optionally, the processing result may further include an identification of an active user of the target website within the target time range; the method may further comprise:
for each type, performing descending ranking on the user according to the quantity of information corresponding to the type published in the target website by the user in the target time range;
and determining the users n before ranking as the active users of the target website in the target time range, wherein n is a preset value.
Specifically, in practical applications, a specific process for implementing the above steps may include: according to data corresponding to the spiD # assetType # usercode num, taking the spiD # assetType # INTmax-num as a key value, and performing descending ranking on the users, wherein the data format is the spiD # assetType # INTmax-num [ usercode, usercode, … ], and [ usercode, usercode, … ] is the ranked user identification; and determining users corresponding to the first n user identifications in the user identifications of [ usercode, usercode, … ] as active users of the target website within the target time range.
