Label and Explanation Variation in LLM-Based Annotation: a Case Study in Natural Language Inference (2026.acl-long)
Copied to clipboard
| Challenge: | Large language models (LLMs) have shown considerable promise for annotation purposes, but questions remain about their ability to capture human label variation (HLV) label variation is genuine disagreement between annotators observed across NLP tasks. |
| Approach: | They investigate how label and explanation variation manifests within and across LLMs with respect to the Natural Language Inference task. |
| Outcome: | The proposed models generate label distributions similar to humans but exhibit distinct, idiosyncratic judgments and disagreement patterns. |

| Challenge: | Human label variation arises when multiple human annotators provide different labels for valid reasons. |
| Approach: | They propose to use crowd workers to represent human judgment distributions or expert linguists to provide detailed explanations for their chosen labels. |
| Outcome: | The proposed model can approximate human judgment distributions using a small number of expert labels and explanations. |

| Challenge: | Existing work on label variation and annotation errors has focused on them in isolation. |
| Approach: | They propose a 2-round annotation procedure to separate human label variation from annotation errors by pairing valid explanations with annotators' validations. |
| Outcome: | The proposed procedure is based on the NLI task in English and contains 7,732 valid judgements on 1,933 explanations for 500 re-annotated items. |
Beyond Demographics: Fine-tuning Large Language Models to Predict Individuals’ Subjective Text Perceptions (2025.acl-long)
Copied to clipboard
| Challenge: | Recent work has shown that LLMs perform poorly when prompted with sociodemographic attributes, suggesting limited inherent sociodemography knowledge. |
| Approach: | They propose to train large language models to be accurate sociodemographic models of annotator variation by using a curated dataset of five tasks with standardized sociodemography. |
| Outcome: | The proposed models improve in sociodemographic prompting when trained but this performance gain is largely due to models learning annotator-specific behaviour rather than sociodemography. |

| Challenge: | Natural Language Inference (NLI) datasets often exhibit label variation. |
| Approach: | They extend LiTEx taxonomy to two NLI datasets and jointly analyze label variation and label variation. |
| Outcome: | The proposed model combines explanations as a lens to analyze variation in NLI annotations and examine individual differences in reasoning. |

| Challenge: | Demographics and cultural background of annotators influence the labels they assign in text annotation. |
| Approach: | They examine the attributes of human annotators LLMs inherently mimic and compare them to demographic-conditioned prompts and placebo-conditioned ones. |
| Outcome: | The proposed model incorporates demographics and cultural background into the output of the large language models (LLMs) to evaluate which attributes of human annotators LLMs inherently mimic. |

| Challenge: | Variation in human annotation (i.e., disagreements) is common in NLP, but it is unclear whether it is possible to model this variation in LLMs. |
| Approach: | They evaluate the influence of different reasoning settings on LLM disagreement modeling . RLVR-style reasoning degrades performance in disagreement modeling, they find . |
| Outcome: | The proposed reasoning settings improve LLM disagreement modeling, while RLVR-style reasoning degrades it. |
