Example

[0138] First embodiment

[0139] Please refer to figure 1 , Which is a structural diagram of the product search system of this application. The system includes: at least one commodity search server 1, a client terminal 2, and a model building device 3.

[0140] The commodity search server 1, which can also be called a commodity search engine, is used to receive a commodity search request for a user-specified search term sent by the client terminal 2; if the search term is a few result terms, it matches the search term If the number of commodity objects is less than the threshold of commodity quantity, the central word of the search term is extracted through the central word extraction model; the commodity object matching the central word is determined; the commodity object is sent back to the client 2.

[0141] The client terminal 2 is configured to send the commodity search request to the server; receive and display the commodity object returned by the server.

[0142] The client te...

[0213] Second embodiment

[0214] Corresponding to the aforementioned commodity search system, this application also provides a commodity search method. Please refer to Image 6 , Which is a flowchart of an embodiment of a product search method provided by this application. The product search device of the main body of the method is also called a product search engine. The device is usually deployed on a server, but is not limited to a server. It may be any device capable of implementing the commodity search method.

[0215] A product search method provided by this application includes:

[0216] Step S601: Receive a product search request for a user-specified search term sent by the client.

[0217] The client terminal includes, but is not limited to, mobile communication equipment, namely: a mobile phone or a smart phone in general, and also includes terminal equipment such as personal computers, PADs, and iPads.

[0218] The users include consumers of fresh food e-commerce. The use...

[0269] The third embodiment

[0270] In the foregoing embodiment, a product search method is provided. Correspondingly, this application also provides a product search device. This device corresponds to the embodiment of the above method.

[0271] Please see Figure 7 , Which is a schematic diagram of an embodiment of the product search device of this application. Since the device embodiment is basically similar to the method embodiment, the description is relatively simple, and the relevant part can refer to the part of the description of the method embodiment. The device embodiments described below are merely illustrative.

[0272] This application additionally provides a product search device, including:

[0273] The request receiving unit 701 is configured to receive a product search request for a user-specified search term sent by the client;

[0274] The central word processing unit 703 is configured to extract the central word of the search word through the central word extrac...

Abstract

The invention discloses a commodity search system, a commodity search method and device, a head word extraction model construction method and device and electronic equipment. The method comprises thesteps that a search server in a commodity search system receives a commodity search request sent by a client for a search term specified by a user, if the search words are zero and few result words, extracting a central word of the search word through a central word extraction model, determining a commodity object matched with the central word, and returning the commodity object to the client, thecentral word extraction model being a model obtained by learning from a corresponding record set between the commodity title and the central word annotation data through a machine learning algorithm.By the adoption of the processing mode, the central words of the search words are automatically extracted through the central word extraction model, and then commodity search is conducted according to the central words; therefore, the head word extraction efficiency and accuracy can be effectively improved, the call completion rate and the call accuracy rate of the search result are improved, anduser conversion and enterprise benefit improvement are brought.

Description

technical field [0001] The present application relates to the field of search technology, in particular to a product search system, a product search method and device, a central word extraction model construction method and device, and electronic equipment. Background technique [0002] Fresh food e-commerce has developed along with the general trend of e-commerce development. In the fresh commodity search scenario, due to reasons such as the selection of search terms and the business characteristics of fresh commodities, there is often a problem that the commodity cannot be searched or only a small number of commodities can be searched, that is, the search results are zero or few. In order to avoid zero and few search results, it is necessary to carry out semantic processing on the search terms, determine their core words, and conduct commodity searches based on the core words to improve the recall rate of search results. [0003] A typical method for determining the centr...
