METHOD AND APPARATUS FOR TRAINING SEARCH MODEL, AND METHOD AND APPARATUS FOR SEARCHING FOR TARGET OBJECT

摘要

Embodiments of the present disclosure relate to a method for training a search model, a method for searching a target object, and an apparatus therefor, and to the field of machine learning. The method includes obtaining a first sample data set for training a search model based on sample query information. The method may further include determining additional query information associated with the sample query information based on the pre-built knowledge base. Also, the method may further include obtaining a second sample data set for training the search model based on the additional query information, the second sample data set being different from the first sample data set. Also, the method may further include training the search model based on the sample query information, the first sample data set and the second sample data set. The technical solution of the present disclosure completes training of a search model quickly, efficiently, and inexpensively, so that an object relatively related to user query information can be determined.
