Abstract

Addressing issues such as solidified social circles, insufficient interest matching precision, and low conversion rates from online interaction to offline engagement among college students, this paper designs and implements “Yiyou”, a campus interest-based social application built on OpenHarmony. The application adopts a front-end and back-end separated layered architecture and integrates a hybrid recommendation algorithm combining implicit-feedback-based tag weight quantification with collaborative filtering to enable personalized event recommendations. Utilizing OpenHarmony's distributed data management capabilities, the system achieves preliminary data synchronization across multiple devices. Its functional modules comprise four modules including interest discovery, friend interaction, event organization, and personal management, forming a complete social chain from online matching to offline participation. Preliminary on-campus testing confirms stable operation of all functional modules, accumulating practical experience for campus social application development based on domestic operating systems.
