An unsupervised framework for tracing textual sources of moral change (2021.findings-emnlp)
Copied to clipboard
| Challenge: | Existing studies on moral sentiment classification and temporal inference of moral sentiment have not quantified the origins of these changes. |
| Approach: | They propose an unsupervised framework for tracing textual sources of moral change toward entities through time. |
| Outcome: | The proposed framework captures fine-grained human moral judgments and identifies coherent source topics of moral change triggered by historical events. |

Text-based inference of moral sentiment change (D19-1)
Copied to clipboard
| Challenge: | Existing work in NLP treats moral sentiment as a flat classification problem, but our framework probes moral sentiment change at multiple levels and captures moral dynamics concerning relevance, polarity, and finegrained categories informed by Moral Foundations Theory. |
| Approach: | They propose a text-based framework that exploits implicit moral biases learned from diachronic word embeddings to probe moral sentiment change over a long historical period. |
| Outcome: | The proposed framework supports inferences of historical shifts in moral sentiment toward concepts such as slavery and democracy over centuries at three incremental levels: moral relevance, moral polarity, and fine-grained moral dimensions. |

Tales of Morality: Comparing Human- and LLM-Generated Moral Stories from Visual Cues (2025.findings-emnlp)
Copied to clipboard
| Challenge: | a recent study has found that stories are central to how humans communicate moral values . |
| Approach: | They compare human- and LLM-generated moral narratives based on images annotated by humans for moral content . authors propose a framework for evaluating moral storytelling in vision-language models . |
| Outcome: | The proposed model compared human- and LLM-generated narratives on images . human stories reflect a balanced distribution of moral foundations and coherent narrative arcs, but LLMs emphasize Care foundation and lack emotional resolution. |
Moral Framing in Politics (MFiP): A new resource and models for moral framing (2025.emnlp-main)
Copied to clipboard
| Challenge: | Recent studies have focused on detecting moral values in political communication, trying to identify moral frames used by political actors or parties to convey their messages. |
| Approach: | They propose to code German parliamentary debates to identify moral framing and to detect subtle differences in politicians’ moral framming. |
| Outcome: | The proposed model distinguishes between different types of moral frames and includes narrative roles, together with the moral foundations for each frame. |
