Abstract

The application discloses a business object search system, method and device, as well as related methods, devices, systems and equipment. Wherein, the business object search method includes: receiving a similar business object search request for the target business object; obtaining the first attribute decoupling representation vector of the target business object and the candidate business object; decoupling the representation vector and attribute value difference information according to the first attribute , determine from the candidate business objects the business objects that have attribute value difference information on the target attribute and are the same or similar to the target attribute on the non-target attribute; and return the similar business object to the requester. Using this processing method, on the one hand, can effectively increase the search dimension of single-factor control search, achieve the search effect based on the user's mind, thereby improving user experience; on the other hand, it can effectively improve the recall and accuracy of search results.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular to a business object search method, device and system, a business object recommendation method, device and system, and electronic equipment. Background technique [0002] When shopping on e-commerce websites, users usually quickly locate the target products through search engines or filters. Traditional search engines provide the following search ranking methods: [0003] (1) Keyword-based query: perform matching search according to the keyword input by the user or prompted by the system, or the product attribute Q, and perform single-attribute or multi-attribute sorting based on the explicit attributes in the entity. The system first builds the index of the entity, such as establishing an inverted index for the title, description text, category attribute, etc., and then expands and rewrites the attribute Q, and then searches the index. [0004] (2) Similarity qu...
