Abstract

The invention discloses an object matching method, a model training method, a product matching method and a storage medium. The method comprises the steps of obtaining an object search request and description information of a target object; and performing semantic matching on the plurality of retrieval keywords and the description information by utilizing a semantic matching model to obtain a target matching result of the object search request and the target object. According to the method and the device, the anti-interference capability of the model on the redundant information of the keyword stacked text is improved by means of adversarial training in the training process of the model, and moreover, the distinguishing of the contrast learning enhancement model on positive and negative samples is fused in the adversarial training process, so that the characterization capability of the object search request and the description information of the target object is improved; therefore, the recognition capability of the semantic matching model on the fine semantics can be improved, the robustness is improved, the technical effect of improving the model recognition accuracy is further achieved, and the technical problem that in the prior art, the recognition accuracy of the semantic matching model is low is solved.

Description

technical field [0001] The present application relates to the field of semantic recognition, and in particular, to an object matching method, a model training method, a product matching method and a storage medium. Background technique [0002] As an important part of the search field, semantic matching can make each user's search result related to the search text input by the user. In order to achieve a better user search experience effect, Transformer-based (Transformer is an attention mechanism-based model) is usually used. pretrained model for semantic matching. [0003] However, Transformer-based pre-training models are usually trained on large-scale general expectations, and cannot be well adapted to scenarios that consider subtle semantic differences. For example, in an online shopping scenario, the search text entered by the user is "300ml fitness In the case of "water cups", the search results will arrange water cups of various volumes in the front and display them...
