Description

[0002] With the continuous development of e-commerce technology, e-commerce platforms strive to recommend commodity information that meets user needs to users to provide a better online shopping experience. When users shop online, they search for the commodity they want to buy through search terms, and the e-commerce system inputs the search terms provided by the user into a search link. The search link includes multiple stages, such as intent recognition, commodity recall, relevance analysis, commodity filtering, rough sorting, fine sorting, and rearrangement, each stage having an out-parameter (out-parameter and in-parameter).

[0047] With reference to the drawings, the technical solutions in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts are within the scope of the present application.

[0048] The scheme of the present application can be implemented based on a terminal with data processing capability, which can be a computer, a server, a cloud, etc.

[0049] Next, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings. Figure 1 The parameter comparison method for the search link of the commodity of the present application can include the following steps:

[0050] Step S110, in response to a link comparison request of a target commodity based on a new function search link, calling an id of an old function search link for comparison with the new function search link.

[0051] Specifically, the id of each search link is unique, and the new function search link also has its search link id, so the id of the new function search link is different from the id of the old function search link.

[0052] Step S120, determining the input and output parameters of the target commodity at each stage in the new function search link according to the id of the new function search link.

[0053] Specifically, the new function search link can include an intent recognition stage, a recall detail stage, a filter detail stage, a coarse ranking algorithm stage, a fine ranking stage and a rearrangement strategy stage in the upstream and downstream order.

[0054] Step S130, determining the input and output parameters of the target commodity at each stage in the old function search link according to the id of the old function search link.

[0055] Specifically, the stages contained in the old function search link are the same as the stages contained in the new function search link, and the upstream and downstream order of each stage of the old function search link is also the same as the upstream and downstream order of each stage contained in the new function search link.

[0056] Step S140, for the input and output parameters of each stage in the new function search link, performing deserialization processing on the input and output parameters of the stage from the data sequence of the PB protocol to obtain a deserialization result of the input and output parameters of the stage.

[0057] The PB protocol is the Protocol Buffers protocol.

[0058] It can be understood that the Protocol Buffers protocol uses a binary format for data serialization, which has higher efficiency and smaller data volume compared with text-based formats such as XML and JSON. The data structure generated by the PB protocol can be converted between different programming languages and different platforms, making data exchange and communication more flexible and convenient. The PB protocol supports adding new fields to existing message types without breaking compatibility with old version data, making it easier to evolve and upgrade data structures. The PB protocol uses simple IDL (Interface Definition Language) to describe data structures, and can generate corresponding data structure classes through a specific compiler, so that developers do not need to manually write tedious serialization and deserialization code. The PB protocol uses a binary format for data serialization, so Protocol Buffers has high efficiency and performance in network transmission and storage.

[0059] Since the PB protocol of each service is customized, special deserialization processing is required to convert the input and output parameter data sequence into a more intuitive input and output parameter deserialization result.

[0060] Step S150, for the input and output parameters of each stage in the old function search link, the input and output parameters of the stage are deserialized from the data sequence of the PB protocol to obtain the input and output parameter deserialization result of the stage.

[0061] Step S160, compare the input and output parameter deserialization result of each stage of the new function search link with the input and output parameter deserialization result of the stage of the old function search link to obtain the new and old function parameter difference result of the stage.

[0062] It can be understood that the input and output parameter deserialization result is an intuitive result, so the input and output parameter deserialization result of each stage of the new function search link can be directly compared with the input and output parameter deserialization result of the stage of the old function search link to obtain the difference between the new and old function input and output parameters in each stage, so as to ensure whether the calling condition of the entire search link meets the expectation.

[0063] The commodity based on a search link parameter comparison method provided by the embodiment compares the parameters of a target commodity based on a new function search link. A link comparison request is responded to, an id of an old function search link compared with the new function search link is called, the id of the new function search link is used to determine the in-out parameters of each stage of the target commodity in the new function search link, the id of the old function search link is used to determine the in-out parameters of each stage of the target commodity in the old function search link, the in-out parameters of each stage of the new function search link are deserialized from a data sequence of a Protocol Buffers protocol to obtain in-out parameter deserialization results of the stage, the in-out parameters of each stage of the old function search link are deserialized from a data sequence of a Protocol Buffers protocol to obtain in-out parameter deserialization results of the stage, the in-out parameter deserialization results of each stage of the new function search link are compared with the in-out parameter deserialization results of the stage of the old function search link to obtain new-old function parameter difference results of the stage. As can be seen, the in-out parameters of each stage of the search link can be deserialized from the data sequence of the Protocol Buffers protocol to be converted into more intuitive in-out parameter deserialization results, so that it is more convenient and easier to troubleshoot or compare the problems existing in the new function of the search link.

[0064] When analyzing the in-out parameter differences between the new and old function search links, it is possible to analyze not only a single stage but also a module composed of upstream and downstream stages to more efficiently and intuitively analyze the differences between the new and old function search links. Based on this, the commodity based on a search link parameter comparison method provided by the application can further include the following processes. Figure 2

[0065] Step S210, the in-out parameters of the target module of the target commodity in the new function search link and the in-out parameters of the target module in the old function search link are determined.

[0066] The target module can include multiple stages with upstream and downstream relationships.

[0067] Step S220, the in-out parameters of each stage of the target module in the new function search link are deserialized from a data sequence of a PB protocol to obtain in-out parameter deserialization results.

[0068] Step S230, the in-out parameters of each stage of the target module in the old function search link are deserialized from a data sequence of a PB protocol to obtain in-out parameter deserialization results.

[0069] ​Step S240, compare the deserialization results of all the in-out parameters of the target module of the new function search link with the deserialization results of all the in-out parameters of the target module of the old function search link, to obtain the difference result of the new and old function parameters of the target module.

[0070] The merchandise parameter comparison method based on search links provided by the embodiment compares the in-out parameters of the target module in the new function search link with the in-out parameters of the target module in the old function search link, deserializes the in-out parameters of the target module in the new and old function search links from the data sequence of the Protocol Buffers protocol, to obtain the deserialization results of the in-out parameters, and finally compares the deserialization results of all the in-out parameters of the target module in the new and old function search links, so that the difference between the new and old function search links can be analyzed more efficiently and more intuitively.

[0071] In some embodiments of the application, the in-out parameter deserialization result storage process mentioned in the foregoing embodiments is introduced. Specifically, the in-out parameter deserialization results of each stage in the old function search link and the in-out parameter deserialization results of the stage in the new function search link can be stored in Redis.
