Description
Recommendation method and device for insurance products, electronic equipment and storage medium Technical Field The application relates to the technical field of artificial intelligence, in particular to a recommendation method and device of insurance products, electronic equipment and a storage medium. Background With the continuous development of insurance markets, insurance products are increasingly abundant in variety, and users face a plurality of difficulties in selecting the insurance products. The current insurance recommendation system refers to the Internet intelligent recommendation field method, and performs user personalized recommendation depending on basic information, historical browsing and purchasing behavior tracks of users. However, for insurance companies that are still mainly in an offline marketing mode, the behavior data of the user is relatively sparse, and even lacks records of online behavior data, and especially for new users, the related data is basically empty, so that the recommendation accuracy is low. Disclosure of Invention The embodiment of the application aims to provide a recommendation method and device for insurance products, electronic equipment and storage media, which are used for solving the technical problem that the existing insurance product recommendation is inaccurate.
