Idea
Multimodal user interest modeling platform enhancing short video recommendations for content platforms and advertisers.
Research Paper
Core Innovation
This paper introduces a multimodal foundation model that fuses video, text, and music into a unified semantic space to generate detailed user interest vectors. It uniquely integrates behavior-driven embeddings from user interactions like viewing, liking, and commenting to capture dynamic interest evolution. This approach improves recommendation accuracy and timeliness, especially for cold-start users, while providing interpretability for transparency.

Research Paper Overview
Multimodal Foundation Model-Driven User Interest Modeling and Behavior Analysis on Short Video Platforms
Summary
This paper presents a multimodal foundation model framework that integrates video frames, text, and music into a unified semantic space to create fine-grained user interest vectors. It incorporates behavior-driven feature embeddings from viewing, liking, and commenting sequences to model dynamic interest evolution, improving recommendation accuracy and timeliness. The approach outperforms mainstream algorithms on public and proprietary datasets, especially for cold-start users, and includes interpretability mechanisms for transparency.
