AI总结:

本文提出SocialRec推荐系统,通过整合用户历史、参与度和个人画像评估推荐得分,采用混合方法解决新用户冷启动问题,并在NeuMF模型上取得HR 0.80和NDCG 0.6的最高成绩。

摘要:

用户活动会影响他们随后与帖子的互动,从而激发用户的兴趣。通常,用户通过评论和使用表情符号与朋友的帖子进行互动,这反映了他们在Facebook、Twitter和Reddit等社交媒体上的兴趣程度。我们的目标是分析用户随时间变化的历史记录,包括他们在各种主题上发布的帖子和参与度。此外,我们考虑了用户的个人资料,寻找他们的活动与社交媒体平台之间的联系。通过整合用户历史、参与度和个人画像,我们旨在基于命中率(HR)评估相关物品分享的推荐得分,并通过归一化折损累积增益(NDCG)评估排序系统的质量,我们在NeuMF上分别取得了0.80和0.6的最高成绩。当出现新用户时,我们的混合方法解决了冷启动问题,而对于新物品,冷启动问题永远不会发生,因为我们考虑了帖子类别的值。为了在冷启动期间提高模型性能,我们引入了协同过滤,通过寻找相似用户并根据最高相似度得分对用户进行排序。

英文摘要:

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.
