Video recommendation method and system

The invention provides a video recommendation method and system. The method comprises the steps of obtaining long and short video features and user features of a user; inputting the user features andthe long and short video features into a preset recommendation model for click rate prediction to obtain a predicted click rate of each to-be-recommended long video and a predicted click rate of eachto-be-recommended short video; and sorting all theto-be-recommended long videos to be recommended and all the to-be-recommended short videos to be recommended according to the predicted click rate ofeach to-be-recommended long video to be recommended and the predicted click rate of each to-be-recommended short video to be recommended, and feeding back a sorting result to the user. In the scheme,the user characteristics and the long and short video characteristics obtained by combining the long video characteristics and the short video characteristics are input into the pre-trained recommendation model to obtain the predicted click rates of the to-be-recommended long video and the to-be-recommended short videos. Sorting t The to-be-recommended long videos and the to-be-recommended short videos are sorted according to the predicted click rate, and feeding back a sorting result is reported to the user, thereby realizing recommendation of different types of information, and improving theuse experience of the user and the accuracy of information recommendation.
