Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Fig. 1 is a device 100 for previewing a second advertisement according to an embodiment of the present invention, and as shown in fig. 1, the device 100 for previewing a second advertisement includes an advertisement playing unit 101 and a second advertisement previewing unit 102.
The advertisement playing unit 101 is configured to determine, according to the received user behavior information, a plurality of advertisements matching the user behavior information, generate a killing-by-second information retrieval request based on the plurality of advertisements, and send the killing-by-second information retrieval request to the killing-by-second forecasting unit 102.
In this embodiment, the advertisement playing unit 101 is used for receiving the traffic of the external system requesting the advertisement, so as to obtain the advertisement matching with the request information. Analyzing the received advertisement request can obtain user behavior information, user pin (user personal identification number), device type and id information, location, ip, time and the like, wherein the user behavior information comprises browsing information, purchasing information and the like of the user. The user behavior information is a basic trigger type information, and in the embodiment, the advertisement matched with the user behavior information can be determined by means of an article-based collaborative filtering algorithm, and the main process of the algorithm comprises the following steps: and calculating the similarity between the commodities, calculating the scores of the commodities browsed or purchased by the user, and recommending the commodities similar to the commodities with higher scores to the user.
The purpose of the advertisement playing unit 101 sending the killing-by-second information retrieval request to the killing-by-second forecasting unit 102 is to determine whether the obtained plurality of advertisements matching the user behavior information are killing-by-second advertisements.
In an alternative embodiment, the advertisement playing unit 101 is also used for playing online advertisements.
The second killing forecasting unit 102 is configured to receive the second killing information retrieval request, determine whether the plurality of advertisements are second killing advertisements according to the second killing information stored in the local cache, and feed back the determined second killing advertisements to the advertisement playing unit, where the second killing information is stored in the local cache in a double-cache manner.
The second killing information can comprise sku information of second killing commodities such as second killing field, second killing starting time and ending time, second killing amount and the like. The sku (stock keeping unit) is a short name for a unified product number, and each product corresponds to a unique sku number. A commodity is called a single commodity when any one of its attributes, such as brand, model, configuration, grade, flower color, packaging capacity, unit, production date, expiration date, usage, price, and place of production, is different from that of other commodities.
In this step, the double caching of the killing information in the local cache by the killing-by-second predicting unit 102 may include:
and storing the acquired killing-by-second information into two data in the local cache, recording the two data as a first data and a second data, wherein the second data is used for data updating under the condition that the killing-by-second prediction unit determines whether the advertisements are killing-by-second advertisements or not based on the first data, and after the second data is updated, the first data is synchronized based on the updated second data.
More specifically, the killing-by-second information in the local cache is stored in the form of a key-value pair (key-value). The key may be a unique identifier (e.g., sku-id) of the second-killing item, and the value may be a hash value of the unique identifier of the item, where the hash value is used to calculate a storage location of second-killing information of the second-killing item. That is, the second killing prediction unit 102 according to the embodiment of the present invention implements a double-cache unordered _ map, implements efficient retrieval by using hash table characteristics, and uses a double-cache update mechanism to ensure lock-free update data. Where unordered _ map is an associative container storing < key, value > key-value pairs, which allows quick indexing by key to its corresponding value. The implementation of efficient retrieval based on hash table characteristics is based on hash buckets. The whole idea is to use space to exchange time and maintain the retrieval efficiency of O (1). For each element a hash value is calculated, from which the storage location of the element is directly calculated.
The second killer forecasting unit 102 may determine whether the plurality of advertisements matching the user behavior information are second killer advertisements based on the second killer information in the local cache, including:
inquiring the killing-per-second information in the local cache, and determining whether the commodities in the advertisements matched with the user behavior information are killing-per-second commodities;
if yes, the advertisement is determined to be a second killing advertisement.
The device for forecasting the second killing advertisement of the embodiment of the invention determines whether the advertisement matched with the user behavior information is the means of second killing advertisement or not by using the second killing information stored in the local cache of the second killing forecasting unit, can add the second killing advertisement to the advertisement queue of the advertisement playing unit in real time and high efficiently, and stores the second killing information in the local cache of the second killing forecasting unit by using a double-cache mechanism, thereby realizing data lock-free updating under the condition of multithreading and improving the operating efficiency.
In an optional embodiment, the advertisement playing unit 101 is further configured to:
and scoring the determined second killing advertisements, sequencing the second killing advertisements according to the sequence of scores from large to small, and playing the second killing advertisements sequenced in the front.
As a specific example, pGmv (Click-Through-Rate, estimated Click Rate), pCtr (Gross merchandisc Volume, estimated turn Rate), and pCvr (Conversion Rate) of a product in the second advertisement are obtained, and the score of the second advertisement is calculated by the parameters, more specifically, the parameters are multiplied by different weights and then added, and the sum obtained by adding is the score of the second advertisement.
In an alternative embodiment, the second advertisement before playing the sequence may be N second advertisements before playing (N is an integer greater than or equal to 1), or M% second advertisements before playing (M is an integer greater than or equal to 1).
Fig. 2 is a device 200 for forecasting second-minute advertisement in accordance with another embodiment of the present invention, and as shown in fig. 2, the device 200 for forecasting second-minute advertisement includes an advertisement playing unit 201, a second-minute advertisement forecasting unit 202, and a second-minute advertisement information base 203.
The advertisement playing unit 201 is mainly responsible for playing online advertisements, receives an advertisement request sent by a front end, analyzes the advertisement request to obtain user behavior information, and requests an advertisement library to recall advertisements according to the user behavior information.
The second killer forecast unit 202 is provided as a high-performance service to the advertisement playing unit, and can provide a real-time second killer information inquiry service.
The killing-by-second information base is used for storing the current killing-by-second information and updating in real time. The killing-by-second information may include: the sku information of various second-killing commodities such as second-killing field, second-killing starting time, second-killing ending time, second-killing amount and the like.
The advertisement playing unit 201 is further configured to determine whether the recalled advertisement is a second killing advertisement according to the real-time second killing information query service provided by the second killing advance notice unit, then score and sort the determined second killing advertisements, and finally return the advertisement sorted in the front to a series of advertisement units at the front end.
As shown in fig. 2, the second killer unit 202 includes a data communication module 2021, a second killer information synchronization module 2022, and an information retrieval module 2023.
The data communication module 2021 is configured to provide the advertisement playing unit 201 with a second-killing real-time query interface. As an example, the data communication module 2021 may be implemented using RPC (Remote Procedure Call).
The killing-by-second information synchronization module 2022 is configured to access the killing-by-second information base at regular time, acquire killing-by-second information of the killing-by-second commodity, and perform double caching on the acquired killing-by-second information in a local cache.
The information retrieval module 2023: the method comprises the steps of storing information acquired from a killing-by-second information base, realizing a double-cache unordered _ map inside, realizing efficient retrieval by utilizing the characteristics of a hash table, and ensuring lock-free updating data by using a double-cache updating mechanism. The double-cache mechanism is to store two data in the system at the same time, and store a currently used data index to represent which data is currently used. When data writing operation exists, modification operation is carried out on the data of the version which is not currently used, and after the modification is finished, the index is switched to use the modified data and the data of the original version is synchronized to be the latest. By the method, data updating without lock under the condition of multithreading is realized, and the operation efficiency is improved.
The internal implementation of the information retrieval module mainly comprises two members: 1. two hash maps (the contents stored by the maps, i.e. the key value pairs above) are provided with a garbage collection function (the garbage collection function is delayed collection) for hot updating system information. 2. An index value (the index value is an atomic variable, hereinafter referred to as index _ no) indicating which data the contents of the exposed data of the current service are. For the outside world, the external service caller does not know which piece of data to use. For the pair, only the information retrieval module can update the value of index _ no.
The second-killing information synchronization module 2022 of this embodiment is configured to pull the second-killing information in the second-killing information base at a thread timing (e.g., 2 hours).
For example, assuming that the current index _ no is 0, the data used by the current information retrieval module is the 0 th data. At this time, the advertisement playing unit has 3 threads to access the second killing forenotice unit, and the data read by the three threads is the 0 th data. If the data update happens to be caught up at the moment, the killing-by-second information synchronization module accesses the killing-by-second information base and writes the new killing-by-second information into the 1 st data. After all the killing-by-seconds information is synchronized, the index _ no is updated to 1, and the subsequent information retrieval module uses the 1 st data for retrieval. In the data updating process, the information retrieval module utilizes the 0 th data to retrieve. Since the 0 th data is not cleared, the apparatus 200 for advertising in advance of the second advertisement can operate normally. After the retrieval is finished, the 0 th data is synchronized by the 1 st data.
Notably, the use of a double cache update mechanism is not suitable for systems that update quickly and frequently. When the time for using the data exceeds the interval of data update, the system hangs up. As an example, the maximum time-consuming threshold of the request for accessing the second-killing noticing unit is 10ms, and the time interval of the second-killing information updating is 2h, so the device 200 for noticing the second-killing advertisement according to the embodiment of the present invention does not have the problem of rewriting after the data updating.
Fig. 3 is a schematic flow chart of updating data by the second killer forecast unit according to the embodiment of the present invention, and as shown in fig. 3, the flow chart includes:
step S301: determining the current time, accessing a killing-by-second information base at the current time, and acquiring killing-by-second information of the killing-by-second commodities;
step S302: updating the acquired killing-by-second information to a local cache, and performing double caching on the acquired killing-by-second information in the local cache;
step S303: calculating the time for next updating of the killing-second information according to the current time and a preset updating period;
step S304: and starting a data updating thread, and accessing the killing-by-second information base according to the time for updating the killing-by-second information next time obtained by calculation.
The data updating process configures the time interval of the killing-by-second information synchronization through a configuration file, and the updating is performed once in two hours by default. And reading the current time and calculating the next updating time when the program is initialized, and accessing the one-time second killing information base to obtain the current second killing commodity information. And traversing to obtain the current second killing commodity information, and adding the second killing commodity information into a local cache of a second killing forecasting system for an advertisement playing end to inquire in real time. And after the program initialization is finished, starting a data updating thread, accessing the killing-by-second information base at regular time according to the previously calculated time interval, and updating the obtained result into a local cache. The local cache updating uses a double-cache updating mechanism to realize multithreading safe lock-free updating.
In the device for forecasting second-killing advertisements in the embodiment of the invention, after the advertisement playing unit acquires the advertisement request sent by the front end, the advertisement playing unit accesses the advertisement library and recalls the advertisements matched with the user behavior information according to the user behavior information (such as browsing and purchasing information) in the advertisement request to generate the advertisement set. Then, the advertisement playing unit accesses the second killing forenotice unit and judges whether the commodities in the advertisement set are second killing commodities, namely whether the advertisements in the advertisement set are second killing advertisements. If yes, the advertisement is marked as a second killing advertisement, and corresponding second killing information is added. And then, scoring and sequencing the second killing advertisements, and finally returning the second killing advertisements which are sequenced in the front to the front end.
