Enhancing Social Media Personalization: Dynamic User Profile Embeddings and Multimodal Contextual Analysis Using Transformer Models

Abstract: This study investigates the impact of dynamic user profile embedding on personalized context-aware experiences in social networks. A comparative analysis of multilingual and English transformer models was performed on a dataset of over twenty million data points. The analysis included a wide range of metrics and performance indicators to compare dynamic profile embeddings versus non-embeddings (effectively static profile embeddings). A comparative study using degradation functions was conducted. Extensive testing and research confirmed that dynamic embedding successfully tracks users' changing tastes and preferences, providing more accurate recommendations and higher user engagement. These results are important for social media platforms aiming to improve user experience through relevant features and sophisticated recommendation engines.
