SocialRec: User Activity Based Post Weighted Dynamic Personalized Post Recommendation System in Social Media
This work addresses the problem of improving recommendation accuracy and handling cold-start issues for users on social media platforms like Facebook and Twitter, though it appears incremental as it builds on existing methods like NeuMF and collaborative filtering.
The paper tackles personalized post recommendation in social media by analyzing user activities, history, and profiles, achieving a Hit Rate of 0.80 and NDCG of 0.6 with NeuMF, and addresses the cold-start problem for new users through a hybrid approach.
User activities can influence their subsequent interactions with a post, generating interest in the user. Typically, users interact with posts from friends by commenting and using reaction emojis, reflecting their level of interest on social media such as Facebook, Twitter, and Reddit. Our objective is to analyze user history over time, including their posts and engagement on various topics. Additionally, we take into account the user's profile, seeking connections between their activities and social media platforms. By integrating user history, engagement, and persona, we aim to assess recommendation scores based on relevant item sharing by Hit Rate (HR) and the quality of the ranking system by Normalized Discounted Cumulative Gain (NDCG), where we achieve the highest for NeuMF 0.80 and 0.6 respectively. Our hybrid approach solves the cold-start problem when there is a new user, for new items cold-start problem will never occur, as we consider the post category values. To improve the performance of the model during cold-start we introduce collaborative filtering by looking for similar users and ranking the users based on the highest similarity scores.
