Dual-Tower Architecture for Enhanced Detection
AdDetector utilizes a novel dual-tower deep neural model to effectively identify advertorials. One tower focuses on extracting hierarchical textual features through a Sentence Encoder (SE) and Sentence Contextualization Encoder (SCE), allowing for fine-grained understanding of semantic relationships between sentences. The second tower integrates social information, including author profiles, non-textual attributes (e.g., follower counts), and interaction patterns from comments, processed via a Graph Convolutional Network (GCN). This combined approach captures both the subtle linguistic cues and the social dynamics that characterize disguised advertisements.
ZHIHU-16K: A Rich, Multi-Topic Chinese Dataset
To address the scarcity of comprehensive data, the researchers curated ZHIHU-16K, the largest publicly available multi-topic Chinese advertorial dataset enriched with extensive social information. Collected from the Zhihu question-answering platform, it includes articles, author details, and comment data across 13 distinct topics. This dataset provides 2,526 advertorials and 13,855 normal articles, enabling robust training and evaluation of AI models in diverse advertising scenarios and user interactions. A rigorous annotation process with Fleiss'k score of 0.815 ensures high data quality and credibility.
Superior Performance and Robustness
AdDetector demonstrates state-of-the-art performance, achieving a 1.29% F1 score improvement in intra-domain detection and a 1.52% improvement in topic transfer settings compared to leading baselines. Its joint training approach, which combines article and sentence classification tasks, significantly enhances transferability to unseen topics. While robust to topic shifts and brand removal, robustness tests indicated that semantic-preserving paraphrasing can still pose a challenge, highlighting areas for future model refinement.
Safeguarding Platform Integrity and User Trust
The practical implications of AdDetector are far-reaching for enterprise AI. For social media platforms, it provides a scalable, automated tool to identify undisclosed advertorials, supporting content moderation and regulatory compliance. Regulatory bodies and consumer protection agencies can leverage its framework to develop evidence-based policies, promoting advertising transparency. For content creators, it underscores the ethical and practical benefits of transparent advertising, as audiences are increasingly adept at detecting concealed promotions. The model fosters a healthier, more trustworthy online environment.

Cross-Platform Adaptability
AdDetector's modular dual-tower architecture facilitates adaptation to diverse social media platforms like Xiaohongshu, WeChat, Bilibili, and TikTok. By separating textual and social feature towers, it can incorporate platform-specific attributes (e.g., image features for Xiaohongshu, video content for TikTok) and abstract universal social dynamics. This modularity, combined with transfer learning, ensures future scalability and relevance.
