Abstract： [Purpose/significance] The behavior of academic literature downloading is an essential step in the process of academic retrieval. Predicting download behavior of academic literature is conducive to the in-depth understanding of the retrieval behavior of researchers, and provides a basis for optimizing retrieval results of academic resource retrieval platforms and restructuring ranking, to improve the retrieval function and service quality of retrieval system.[Method/process] This paper constructed a multi-dimensional feature system of researchers' academic literature download behavior, and proposed two sub-classifiers based on query relevance and user behavior respectively relying on machine learning algorithms. A weighted strategy was adopted to construct a hybrid model of download behavior prediction of academic literature.[Result/conclusion] The experiment results show that the Random Forest algorithm achieves the best performance in both classifiers. Compared to the model trained with only query relevance features, the accuracy of the hybrid model is increased by 2.3%, and the F1 value is increased by 1.3%. The sub-classifiers based on user behavior have higher weights in the hybrid model. "downloads" "whether professional/advanced search is used"and "published time" make a significant contribution to the academic literature download prediction task.
