The framework combines a DistilBERT boundary splitter, an iteratively augmented RoBERTa classifier, a Mistral 7B rewriter, a LLaMA 3.2 3B criteria rater, and a Milvus vector store, wrapped in a Streamlit interface backed by MinIO object storage. On a 163-passage benchmark labelled by GPT-4.1 and a 51-passage expert-reviewed set, the splitter scored 6.137 on a nine-metric composite, surpassing three competing methods, while the tuned RoBERTa model reached 71.4 percent accuracy with a Cohen's kappa of 0.337 on the full benchmark and 87.5 percent accuracy with a kappa of 0.742 on labelled passages, outperforming a climate-focused model and untuned language models.", "body_md": "arXiv:2609.12254v1 Announce Type: new \nAbstract: The climate literature has grown faster than review teams can read it. That gap matters most for a concept like the environmental social tipping point, the threshold at which a small change triggers rapid, self-reinforcing change in a social system. Evidence of this kind of shift is usually contained in one or two paragraphs within a longer document. As a result, existing text mining tools-which categorize entire documents by topic or highlight isolated claims-leave an expanding set of important evidence without any systematic method for discovery or organization. This paper presents an open and modular transformer-based framework that detects and structures social tipping point evidence at the passage level. The framework joins five components into a single deployable workflow: a DistilBERT boundary splitter for segmentation, an iteratively augmented RoBERTa classifier for detection, a Mistral 7B model that rewrites each detected passage for clarity, a LLaMA 3.2 3B model that rates the passage against five published social tipping point criteria, and a Milvus vector store for semantic retrieval. The system is wrapped in a Streamlit interface backed by MinIO object storage. Evaluated on a 163-passage benchmark labelled by GPT-4.1 and a 51-passage set reviewed by experts, the splitter surpassed three competing methods on a nine-metric composite score (6.137). The tuned RoBERTa model achieved 71.4 percent accuracy with a Cohen's kappa of 0.337 on the full benchmark, and 87.5 percent accuracy with a kappa of 0.742 on passages with labels, outperforming both a climate-focused model and untuned language models.", "url": "https://wpnews.pro/news/automated-detection-and-structuring-of-social-tipping-point-evidence-in-climate", "canonical_source": "https://arxiv.org/abs/2609.12254", "published_at": "2026-09-14 04:00:00+00:00", "updated_at": "2026-09-14 04:27:52.058717+00:00", "lang": "en", "topics": ["artificial-intelligence", "machine-learning", "natural-language-processing", "ai-research", "ai-tools"], "entities": ["DistilBERT", "RoBERTa", "Mistral 7B", "LLaMA 3.2 3B", "Milvus", "Streamlit", "MinIO", "GPT-4.1"], "alternates": {"html": "https://wpnews.pro/news/automated-detection-and-structuring-of-social-tipping-point-evidence-in-climate", "markdown": "https://wpnews.pro/news/automated-detection-and-structuring-of-social-tipping-point-evidence-in-climate.md", "text": "https://wpnews.pro/news/automated-detection-and-structuring-of-social-tipping-point-evidence-in-climate.txt", "jsonld": "https://wpnews.pro/news/automated-detection-and-structuring-of-social-tipping-point-evidence-in-climate.jsonld"}}
