More Information
Summary:Embodiments of the invention disclose a ranking model training method and device, electronic equipment and a storage medium. The method comprises the steps of obtaining a sample data pair; performing multi-classification prediction on the correlation between the first query content and a first query result by using a ranking model to obtain a first correlation prediction result, and performing multi-classification prediction on the correlation between the first query content and the second query result to obtain a second correlation prediction result; fitting a first loss between the first correlation prediction result and the first correlation level by using a first loss function, and fitting a second loss between the second correlation prediction result and the second correlation level; determining a correlation prediction comparison result according to the first correlation prediction result and the second correlation prediction result; fitting a third loss between the correlation prediction comparison res
