AAA at SemEval-2026 Task 10: Psycholinguistic Conspiracy Marker Extraction and Detection
Summary
AAA's study for SemEval-2026 Task 10 addresses psycholinguistic conspiracy marker extraction and detection within social media texts. The research focuses on token-level extraction and sentence-level conspiracy classification. It proposes a novel classification method that integrates semantic encoding with large language model reasoning and generation. Specifically, semantic features are extracted using DeBERTa-v3, and explanatory reasoning text is generated by ConspEmoLLM-v2. These two outputs are then combined to enhance the model's ability to recognize implicit conspiratorial logic. The study also includes a systematic comparison of several mainstream pre-trained models for the extraction subtask, providing baseline performance analysis.
Key takeaway
For NLP Engineers developing systems to detect subtle conspiratorial content on social media, this research suggests a powerful hybrid approach. You should consider integrating semantic encoding models like DeBERTa-v3 with large language models such as ConspEmoLLM-v2 for enhanced recognition of implicit conspiratorial logic. This method offers a robust strategy beyond traditional classification.
Key insights
Combining semantic encoding with LLM reasoning enhances detection of implicit conspiratorial logic in social media texts.
Principles
