Abstract
With the rapid development of digital media, the emergence of massive content has led users to face the problem of information overload, making it urgent to develop an efficient intelligent recommendation system to enhance user experience. This study aims to design and implement an intelligent recommendation system for digital media content based on multi-modal feature fusion, which optimizes content matching accuracy and personalized recommendation effects by integrating deep learning and collaborative filtering technologies. Firstly, a unified feature representation fr amework was constructed, encompassing multi-modal data such as text, images, and videos, with Transformer models employed to extract semantic features while introducing attention mechanisms to enhance the weight allocation of critical information. Secondly, the system integrates a user behavior analysis module that utilizes implicit feedback data to dynamically adjust recommendation strategies, thereby adapting to changes in user interests. Experimental results demonstrate that the proposed system achieves over a 15% improvement in recommendation accuracy on multiple public datasets compared to traditional methods, and effectively alleviates the cold-start problem. Additionally, the system supports real-time updates and extensions, exhibiting excellent portability and robustness. The primary innovations of this research lie in the proposal of a multi-modal feature fusion algorithm and a dynamic interest modeling mechanism, providing a novel solution for the field of digital media content recommendation with significant theoretical value and practical application potential.
