Researchers have developed a method to detect Schwartz's 19 human values within single sentences, achieving a macro-F1 score of 0.332. The study compared direct multi-label classification with hierarchical approaches, finding that direct prediction was more efficient under limited computational resources. A key finding was the significant impact of decision-threshold calibration, which improved performance across different models, including RoBERTa-base and even outperforming larger LLMs like QLoRA-tuned models when constrained by budget.
