AI-Powered Music Comment Moderation and Ranking: Models, Challenges, and Business Impact
This article presents a comprehensive overview of AI-driven music comment moderation and ranking systems, detailing business scenarios, model architectures, data processing techniques, performance improvements, and future directions for both QQ Music and K‑Song platforms.
The presentation introduces the background of music comment moderation, comparing QQ Music and K‑Song comment characteristics, and outlines the need for AI to reduce manual review costs.
It describes a multi‑stage quality model that classifies comments into four quality levels (high, good, normal, low) using BERT encodings, sentence‑pair inputs, and data augmentation, and explains how the model suggests actions for automated or assisted moderation.
Two versions of the quality model are detailed: V1 uses a simple BERT classifier, while V2 adds MinHash + LSH for plagiarism detection, a separate sentiment analysis module, and custom embeddings to handle complex sentence structures and domain‑specific vocabulary.
The ranking system combines textual semantic tags (quality, topic, emotion) with posterior factors (likes, replies, surge) and employs a DPP algorithm with LSA‑based topic modeling to diversify top comments, improving user experience.
Business impact results show significant reductions in manual review workload, a 20% efficiency boost for reviewers, and enhanced comment exposure metrics, with future plans to further automate moderation, expand label services, and refine ranking models.
