[0001] The present disclosure relates to the field of computer technology, and in particular to a data acquisition method, device, electronic device and storage medium. Background Art

[0002] With the advent of the big data era, numerous scenarios enabled by intelligent data have emerged. The advertising field, as an important landing scenario, has spawned dynamic product advertisements (DPA, Dynamic Product Ads) to meet advertisers' demands for batch creative production and efficient marketing conversion.

[0003] Among them, dynamic product advertisements require updates to the products in the product library. In related technologies, the method of uploading product information online is only applicable to a small number of product information entry scenarios, and the update of product information requires manual triggering; the method of manually uploading XML files requires redevelopment of XML file uploads when updating; the method of automatically pulling files regularly has a fixed update frequency and cannot update product information in a timely and accurate manner, and has poor timeliness. During big sales or events, sensitive data such as inventory, prices, promotional information, etc. may only be updated during a certain period of time, and remain unchanged during other periods, which will cause message delays during periods of frequent information changes, and pull the same information during periods of stable information.

[0048] It should be understood that Figure 1 The number of terminal devices, message centers and servers in the example is only for illustration, and any number of terminal devices, message centers and servers may be provided according to actual needs.

[0049] It should be noted that the above application scenarios are only shown to facilitate understanding of the spirit and principle of the present disclosure, and the embodiments of the present disclosure are not limited in this respect. On the contrary, the embodiments of the present disclosure can be applied to any applicable scenario.

[0050] Below, each step of the data acquisition method in the exemplary embodiment of the present disclosure will be described in more detail with reference to the accompanying drawings and embodiments.

[0051] Figure 3 is a flow chart of a data acquisition method according to an exemplary embodiment. The method provided by the embodiment of the present disclosure can be performed as follows Figure 1 The process is executed in the message center shown in the figure, but the present disclosure is not limited thereto.

[0052] like Figure 3 As shown, the data acquisition method provided by the embodiment of the present disclosure may include the following steps.

[0053] In step S302, a target attribute update message of a target item among the items is obtained from the client, and the target attribute update message includes an updated target attribute.

[0054] In the embodiments of the present disclosure, the article may be a commodity, and the article may include daily necessities, electronic products, books, food, etc., and the present disclosure does not impose any limitation on this.

[0055] The attributes of an item may be, for example, the item name, item ID, store name, item price, etc.

[0056] The target item may be an item whose attribute is changed, and the target attribute may be an attribute whose attribute is changed.

[0057] Let's take the target item as laundry detergent and the target attribute as price as an example.

[0058] If the price of the washing powder changes, the client can send a price update message of the washing powder to the message center, where the price update message includes the updated price, and the message center obtains the price update message of the washing powder from the client.

[0059] In step S304, a fixed time interval for actively pulling the item file of the item is obtained from the server, and the item file of the item is stored in the target storage device.

[0060] In the embodiment of the present disclosure, the server can set a fixed time interval for the server to actively pull the item files of the item from the target storage device, where the target storage device can be a cloud storage device, and the fixed time interval can be set according to actual conditions, for example, 1 hour, 1 day, 1 week, etc.

[0061] The server may send the set fixed time interval for actively pulling item files to the message center, and the message center may obtain the fixed time interval from the server.

[0062] In step S306, a notification message is generated according to the target attribute update message of the target object and the fixed time interval, and the notification message is used to notify the server to pull the target object file of the target object from the target storage device.

[0063] In the disclosed embodiment, the notification message may be generated by a weighted average method, a multi-priority queue method, or a fixed number of commodities method.

[0064] In the disclosed embodiment, the message center can determine the current information entropy based on the updated target attributes in the target attribute update message of the target item and the fixed time interval; if the current information entropy is greater than or equal to the information entropy threshold, a notification message is generated to pull the target item file corresponding to the target item; if the current information entropy is less than the information entropy threshold, and the current time is greater than or equal to the time when the server pulls the file, no notification message is generated; if the current information entropy is a preset value, a notification message is generated not to pull the target item file corresponding to the target item.

[0065] In the disclosed embodiment, the message center can generate a queue corresponding to the attributes of the item based on the attributes of the item, and add the target item to the queue corresponding to the target attribute; determine the total priority based on the priority of each queue and the number of items in each queue; if the total priority is greater than or equal to the priority threshold, generate a notification message to pull the target item file corresponding to the target item; if the total priority is less than the priority threshold, and the current time is greater than or equal to the time when the server pulls the file, no notification message is generated; if the total priority is a preset value, generate a notification message that does not pull the target item file corresponding to the target item.

[0066] In the disclosed embodiment, the message center may compare the update quantity of the target item with a quantity threshold; if the update quantity is greater than or equal to the quantity threshold, a notification message is generated to pull the target item file corresponding to the target item; if the update quantity is less than the quantity threshold, and the current time is greater than or equal to the time when the server pulls the file, no notification message is generated, and the time when the server pulls the file is determined according to a fixed time interval; if the update quantity is a preset value, a notification message is generated not to pull the target item file corresponding to the target item.

[0067] After the message center generates the notification message, it can send the notification message to the server. After receiving the notification message, the server can pull the target object file of the target object from the target storage device.

[0068] The data acquisition method provided by the embodiment of the present disclosure can be used by a message center to update a target attribute message of a target item and obtain a fixed time interval for actively pulling the item file of the item on the server side, intelligently determine the timing for the server side to pull the target item file of the target item, generate a notification message, and notify the server side to pull the target item file of the target item from the target storage device; the method can determine the timing for the server to pull the updated file according to the change of the item information, and can improve the efficiency of the server side in updating the item file, so that the server side can pull the updated item file in a timely and accurate manner.

[0069] Figure 4is a flow chart showing another data acquisition method according to an exemplary embodiment.

[0070] In the embodiment of the present disclosure, Figure 3 Based on the data acquisition method shown, Figure 4 The data acquisition method shown further provides how to generate a notification message according to the target attribute update message and the fixed time interval of the target object, that is, provides an embodiment of the above step S306.

[0071] like Figure 4 As shown, step S306 may include the following steps.

[0072] In step S402, the current time window is determined according to the updated target attributes and their corresponding weights.

[0073] In the disclosed embodiments, different weights may be set for different attributes of an item. For example, the price of an item has a greater impact on the item, so the weight corresponding to the price may be set higher; the category of an item has a smaller impact on the item, so the weight corresponding to the category may be set lower.

[0074] In the embodiment of the present disclosure, the time window may be initialized first, and the initial value of the time window may be set to T0, where T0 may be 0.

[0075] In the embodiment of the present disclosure, the current time window can be determined according to the following formula:

[0076]

[0077] Among them, TIME(range) represents the current time window, K represents the updated target attribute, and V represents the weight corresponding to the target attribute.

[0078] In step S404, the current information entropy is determined according to the current time window and the fixed time interval.

[0079] In the embodiment of the present disclosure, the current information entropy can be determined according to the following formula:

[0080] R=TIME(range) / T1

[0081] Among them, R represents the current information entropy, and T1 represents a fixed time interval.

[0082] In step S406, if the current information entropy is greater than or equal to the information entropy threshold, a notification message is generated to pull the target item file corresponding to the target item.

[0083] The information entropy threshold can be set according to actual conditions, and the information entropy threshold can be represented by R0.

[0084] In the disclosed embodiment, if the current information entropy R is greater than or equal to R0, a notification message for pulling the target item file corresponding to the target item is generated to notify the server to immediately pull the target item file.

[0085] In the disclosed embodiment, after generating a notification message for pulling a target item file corresponding to a target item, the message center may reset the current time window and the current information entropy.

[0086] In step S408, if the current information entropy is less than the information entropy threshold, and the current time is greater than or equal to the time when the server pulls the file, no notification message is generated, and the time when the server pulls the file is determined according to a fixed time interval.

[0087] In the embodiment of the present disclosure, the time when the server pulls the file can be set according to a fixed time interval. For example, if the fixed time interval is 1 hour, the time when the server pulls the file can be 1:00, 2:00, 3:00, etc.

[0088] If the current information entropy R is less than the information entropy threshold R0, and the current time is greater than or equal to the time when the server pulls the file, no notification message is generated.

[0089] Among them, the server can pull the target item file from the target storage device at a fixed time interval. When the current time is greater than or equal to the time when the server pulls the file, the server has pulled the target item file from the target storage device at the time when the server pulls the file, and the current information entropy is less than the information entropy threshold, that is, the server does not need to pull the target item file from the target storage device at this time, and the message center does not generate a notification message.

[0090] In step S410, if the current information entropy is a preset value, a notification message is generated not to pull the target item file corresponding to the target item.

[0091] The preset value can be set to 0 or can be set according to actual conditions.

[0092] In the disclosed embodiment, if the current information entropy is 0, that is, no item is updated, the message center generates a notification message not to pull the target item file corresponding to the target item, and sends the notification message to the server. After receiving the notification message, the server does not pull the target item file.

[0093] The data acquisition method provided by the embodiment of the present disclosure intelligently determines the timing of triggering file pulling by setting a time window, intelligently determines the weights corresponding to the attributes of different items by configuring rule strategies, and determines the timing of pulling files, thereby improving the updating efficiency of item files and solving the problem of items not being able to be updated in time and low updating efficiency.

[0094] Figure 5is a flow chart showing another data acquisition method according to an exemplary embodiment.

[0095] In the embodiment of the present disclosure, Figure 3 Based on the data acquisition method shown, Figure 5 The data acquisition method shown further provides how to generate a notification message according to the target attribute update message and the fixed time interval of the target object, that is, provides an embodiment of the above step S306.

[0096] like Figure 5 As shown, step S306 may include the following steps.

[0097] In step S502, based on the attributes of the items, a queue corresponding to the attributes of the items is generated.

[0098] In the disclosed embodiment, a queue corresponding to the attribute of each item may be set for the attribute of each item, and each queue includes items whose attributes have changed.

[0099] For example, the items that have changed are item A, item B, and item C. The price attribute and category attribute of item A have changed, the price attribute and store name attribute of item B have changed, and the store name attribute of item C has changed. Then the queue corresponding to the price attribute includes item A and item B, the queue corresponding to the category attribute includes item A, and the queue corresponding to the store name attribute includes item B and item C.

[0100] In step S504, the target item is added to a queue corresponding to the target attribute.

[0101] For example, the target item is item D, and the target attribute is price, that is, if the price attribute of the target item changes, item D can be added to the queue corresponding to the price attribute.

[0102] In step S506, the overall priority is determined according to the priority of each queue and the number of items in each queue.

[0103] In the disclosed embodiment, the priority of each queue corresponding to each attribute can be set according to the importance of the attribute. For example, the price attribute is more important to the item, and the priority of the queue corresponding to the price attribute can be set higher; the store name attribute is not important to the item, and the priority of the queue corresponding to the store name attribute can be set lower.

[0104] In the disclosed embodiment, the message center may determine the overall priority based on the priority of each queue and the number of items in each queue.

[0105] For example, the priority of each queue can be multiplied by the number of items in each queue and then summed to obtain the total priority.

[0106] In step S508, if the total priority is greater than or equal to the priority threshold, a notification message is generated to pull the target item file corresponding to the target item.

[0107] The priority threshold can be set according to actual conditions.

[0108] In the disclosed embodiment, if the total priority is greater than or equal to the priority threshold, a notification message for pulling the target item file corresponding to the target item is generated to notify the server to immediately pull the target item file.

[0109] In step S510, if the total priority is less than the priority threshold, and the current time is greater than or equal to the time when the server pulls the file, no notification message is generated, and the time when the server pulls the file is determined according to a fixed time interval.

[0110] In the embodiment of the present disclosure, the time when the server pulls the file can be set according to a fixed time interval. For example, if the fixed time interval is 1 hour, the time when the server pulls the file can be 1:00, 2:00, 3:00, etc.

[0111] If the total priority is less than the priority threshold, and the current time is greater than or equal to the time when the server pulls the file, no notification message is generated.

[0112] Among them, the server can pull the target item file from the target storage device at a fixed time interval. When the current time is greater than or equal to the time when the server pulls the file, the server has pulled the target item file from the target storage device at the time when the server pulls the file, and the current information entropy is less than the information entropy threshold, that is, the server does not need to pull the target item file from the target storage device at this time, and the message center does not generate a notification message.

[0113] In step S512, if the total priority is a preset value, a notification message is generated not to pull the target item file corresponding to the target item.

[0114] The preset value can be set to 0 or can be set according to actual conditions.

[0115] In the disclosed embodiment, if the total priority is 0, that is, no item is updated, the message center generates a notification message not to pull the target item file corresponding to the target item, and sends the notification message to the server. After receiving the notification message, the server does not pull the target item file.

[0116] Figure 6 is a flow chart showing another data acquisition method according to an exemplary embodiment.

[0117] In the embodiment of the present disclosure, Figure 3 Based on the data acquisition method shown, Figure 6 The data acquisition method shown further provides how to generate a notification message according to the target attribute update message and the fixed time interval of the target object, that is, provides an embodiment of the above step S306.

[0118] like Figure 6 As shown, step S306 may include the following steps.

[0119] In step S602, the update quantity of the target item is determined.

[0120] In the disclosed embodiment, a globally unified update quantity update of the target items may be set, and the initial value of the update quantity update may be set to 0.

[0121] In step S604, if the update quantity is greater than or equal to the quantity threshold, a notification message is generated to pull the target item file corresponding to the target item.

[0122] The quantity threshold can be set according to actual conditions.

[0123] In the disclosed embodiment, if the update quantity is greater than or equal to the quantity threshold, a notification message for pulling the target item file corresponding to the target item is generated to notify the server to immediately pull the target item file.

[0124] In step S606, if the update quantity is less than the quantity threshold, and the current time is greater than or equal to the time when the server pulls the file, no notification message is generated, and the time when the server pulls the file is determined according to a fixed time interval.

[0125] In the embodiment of the present disclosure, the time when the server pulls the file can be set according to a fixed time interval. For example, if the fixed time interval is 1 hour, the time when the server pulls the file can be 1:00, 2:00, 3:00, etc.

[0126] If the number of updates is less than the number threshold, and the current time is greater than or equal to the time when the server pulls the file, no notification message is generated.

[0127] Among them, the server can pull the target item file from the target storage device at a fixed time interval. When the current time is greater than or equal to the time when the server pulls the file, the server has pulled the target item file from the target storage device at the time when the server pulls the file, and the current information entropy is less than the information entropy threshold, that is, the server does not need to pull the target item file from the target storage device at this time, and the message center does not generate a notification message.

[0128] In step S608, if the update quantity is a preset value, a notification message is generated not to pull the target item file corresponding to the target item.

[0129] The preset value can be set to 0 or can be set according to actual conditions.

[0130] In the disclosed embodiment, if the update quantity is 0, that is, no item is updated, the message center generates a notification message not to pull the target item file corresponding to the target item, and sends the notification message to the server. After receiving the notification message, the server does not pull the target item file.

[0131] Figure 7 FIG. 1 is a flow chart of another data acquisition method according to an exemplary embodiment. The method provided in the embodiment of the present disclosure may be performed as follows: Figure 1 The process is executed in the client shown in the figure, but the present disclosure is not limited to this.

[0132] like Figure 7 As shown, the data acquisition method provided by the embodiment of the present disclosure may include the following steps.

[0133] In step S702, source data of the item is obtained.

[0134] In the disclosed embodiment, the user can upload the source data of the item through the client, and the user can also select the file format of the source data, for example, XML (Extensible Markup Language) file format, SQL (Structured Query Language) file format, CVS (Concurrent Version System) file format, etc.

[0135] In the disclosed embodiment, users can upload files in various formats, and the usage threshold of the client is relatively low.

[0136] The item may be a commodity, and the source data of the commodity may include information details of the commodity, such as price, number, brand, etc.

[0137] In the disclosed embodiment, the source data of the item may be verified first, for example, whether the data source of the source data of the item is valid, whether the path exists, whether the file format is supported, etc.

[0138] In step S704, the format of the source data of the item is converted to obtain an item file in a preset format.

[0139] In the embodiment of the present disclosure, the preset format may be a Map file format, a List file format, an XML file format, an SQL file format, a CSV file format, and the like.

[0140] In the disclosed embodiment, the user can select a preset format through the client. The client can parse the source data through SDK (Software Development Kit) according to the preset format selected by the user, and convert the source data of the item into an item file in the preset format.

[0141] In the embodiment of the present disclosure, files of multiple formats can be supported as the transmission medium for item information. Compared with the related art that only supports XML files, the embodiment of the present disclosure can support heterogeneous data sources such as JSON and SQL, and can have higher processing efficiency and experience diversity.

[0142] In addition, by supporting multiple heterogeneous data source modes, different systems can avoid redevelopment based on their own existing technical solutions, thereby improving development flexibility and efficiency; secondly, it reduces the granularity of concurrent competition in a distributed environment and increases the concurrency of product information updates.

[0143] In the disclosed embodiment, a target generation file entity class may be selected according to a preset format; and an item file of a preset format may be generated through the target generation file entity class.

[0144] Among them, SDK can provide development components for the product library for source data parsing, target item file generation and target item file verification.

[0145] In step S706, the item file in the preset format is stored in the target storage device.

[0146] In the embodiment of the present disclosure, the target storage device may be a cloud storage device.

[0147] In the disclosed embodiment, the item file in a preset format may be first checked to determine whether it satisfies preset rules, for example, a structure check and a data validity check may be performed on the item file.

[0148] In step S708, an item index file of the item file is obtained, and the item index file is configured on the server.

[0149] In the disclosed embodiment, the client can encapsulate the item file, obtain the Sitemap item index file, and configure the Sitemap index file on the server. The server can obtain the item index file, obtain the item file generated by the client through the item index file, and build a product library.

[0150] In step S710, the target item to be updated and its target attribute are obtained.

[0151] In the disclosed embodiment, when a target attribute of a target item is updated, the client may be notified via a message such as MQ (MessageQueue). After receiving the message, the client may obtain the target item to be updated and its target attribute.

[0152] In step S712, the item file and the item index file in a preset format are updated according to the target item to be updated and its target attribute.

[0153] In the disclosed embodiment, the client may update the item file and the item index file in a full coverage mode or an update mode.

[0154] The full coverage mode can, for example, allow the client to obtain the item file corresponding to the target item to be updated, and obtain all items corresponding to the item file; perform new logic on all items to generate a new item file; upload the new item file to the cloud storage device, overwrite the original item file, and update the item index file.

[0155] When the number of items in a single item file is small, it is efficient to generate the item file in full coverage mode, avoiding file downloading, indexing, and updating operations.

[0156] In an exemplary embodiment, according to the target item to be updated in the items and its target attributes, the item file and the item index file in a preset format are updated, including: obtaining the target item file corresponding to the target item to be updated from the target storage medium; updating the target attributes in the target item file to obtain an updated target item file; and storing the updated target item file in the target storage device.

[0157] The update mode may be, for example, that the client obtains the item file containing the target item to be updated from the cloud storage medium, downloads the item file to the local computer, updates the information corresponding to the target item to be updated in the item file through the identifier of the target item to be updated, uploads the updated item file to the cloud storage device, and updates the item index file.

[0158] The update mode can reduce the granularity of concurrent contention in a distributed environment and increase the concurrency of item information updates.

[0159] In step S714, the updated item file in the preset format is stored in the target storage device, and the updated item index file is configured on the server.

[0160] In the embodiment of the present disclosure, the client can store the updated item file in a preset format in a target storage device, so that the server can subsequently obtain the updated item file from the target storage device; the client can configure the updated item index file on the server, so that the server can obtain the updated item file according to the updated item index file.

[0161] In step S716, a target attribute update message of the target item is sent to the message center, where the target attribute update message includes the updated target attribute.

[0162] In the disclosed embodiment, the client may send a target attribute update message of the target item to the message center, so that the message center can notify the server to pull the updated item file through a time window-based message notification mechanism.

[0163] Figure 8 FIG. 1 is a flow chart of another data acquisition method according to an exemplary embodiment. The method provided in the embodiment of the present disclosure may be performed as follows: Figure 1 The process is executed in the server shown, but the present disclosure is not limited to this.

[0164] like Figure 8 As shown, the data acquisition method provided by the embodiment of the present disclosure may include the following steps.

[0165] In step S802, an item index file of an item is obtained from a client, the item file of the item is stored in a target storage device, and the item index file includes a storage index of the item file in the target storage device.

[0166] In the disclosed embodiment, the server may obtain an item index file of an item from the client, and based on the item index file, the server may obtain an item file corresponding to the item index file from a cloud storage device.

[0167] In step S804, a fixed time interval for actively pulling item files from the target storage device according to the item index file is set.

[0168] In the embodiment of the present disclosure, the server can pre-set a fixed time interval for actively pulling item files from the cloud storage device based on the item index file, and determine the time to actively pull item files based on the fixed time interval. At every fixed time interval, the server can actively pull item files from the cloud storage device for update.

[0169] In step S806, when the target attribute of the target item in the items is updated, the updated item index file is obtained from the client.

[0170] In the disclosed embodiment, when the target attribute of a target item in the items is updated, the server can obtain the updated item index file from the client, so that the server can subsequently pull the updated item file from the cloud storage device.

[0171] In step S808, a notification message is received from the message center, where the notification message is generated based on the update information of the target attribute of the target item and a fixed time interval.

[0172] In the embodiment of the present disclosure, the server can receive a notification message from the message center. If the notification message received is for pulling the target item file, the server immediately pulls the target item file from the cloud storage device; if the notification message received is for not pulling the target item file, it means that the item file has not been updated at present, and the server may not pull the target item file even if the time for pulling the file arrives.

[0173] In step S810, in response to the notification message, a target item file of a target item corresponding to the updated item index file is pulled from a target storage device.

[0174] In the disclosed embodiment, the server may pull the target item file of the target item corresponding to the updated item index file from the cloud storage device.

[0175] Fig. 9 The figure is a schematic diagram showing a server-side parsing file according to an exemplary embodiment.

[0176] In the present disclosure, Fig. 9 As shown, after pulling the target item file (target data file), the server can determine the file parsing rules according to the file format of the target item file. For example, if the file format of the target item file is Map, select a parsing mode that can parse Map; if the file format of the target item file is List, select a parsing mode that can parse List.

[0177] The server can parse the target item file content into the unified data specification of the commodity library and store it, realizing the standardization and normalization of heterogeneous data. The server can also perform legality verification on the parsed target item file.

[0178] In step S812, a directional display link including the target object file is pushed to the target media playback platform.

[0179] The target media playback platform may be, for example, a shopping application, a ticket purchasing platform, etc., and the directional display link may be, for example, an advertisement.

[0180] For example, the server may push an advertisement including a target item file to a shopping application.

[0181] The data acquisition method provided by the embodiment of the present disclosure can display advertisements to users in a timely and effective manner based on updated item information, thereby avoiding the problem of false advertising caused by untimely information updates in advertisements.
