The invention relates to a multi-factor weight assignment correction method and apparatus, a computer device and a storage medium. The method comprises the steps of obtaining a weight initial value ofeach feature under a target object; calculating the contribution degree of the target article relative to all articles under the target article category to obtain an article contribution value; calculating the contribution degree of each feature under the target article relative to the features corresponding to all articles under the target article category to obtain a feature contribution value;generating a weight correction value according to the object contribution value and the feature contribution value; and correcting the weight initial value according to the weight correction value toobtain a real feature weight value. Based on the method, the weight correction value of each feature of the article is calculated according to the real-time data representation of the article, and then the weight of each feature of the article is adaptively adjusted through the weight correction value, so that the feature weight does not need to be manually set according to a large number of tests, and the research and development cost is saved.
Description
technical field [0001] The present application relates to the field of computer technology, and in particular to a multi-factor weight assignment correction method, device, computer equipment and storage medium. Background technique [0002] In some common item sorting scenarios, it is usually necessary to sort according to the score (target) of the item. The score usually requires many features to participate in the calculation, and each feature (feature) will be given different weights (weight), that is, the contribution to this score is different. However, the feature weights currently involved in the calculation are basically based on the calculation model, combined with certain business experience, and based on a large number of tests to set or adjust the feature weights to ensure the scientific effect of online ranking. The calculation process is cumbersome and requires manual setting or adjustment, and the research and development costs are relatively high. Content...
