Existing tools such as Label Studio, Doccano, LightTag and Prodigy each have drawbacks: some depend on external hosting, some offer little layout flexibility for complex designs, and some cost too much for small teams.

Zero-shot sociodemographic prompting of LLMs is known to work poorly. This paper asks whether fine-tuning can turn LLMs into accurate demographic models of annotators. ## All works 4 works of theirs in our library, the most cited first; 2 with a page here, the others link their original until we summarise them. 1. **[When “A Helpful Assistant” Is Not Really Helpful: Personas in System Prompts Do Not Improve Performances of Large Language Models ↗](https://aclanthology.org/2024.findings-emnlp.888/) Findings of the Association for Computational Linguistics: EMNLP 2024 · no summary yet**Mingqian Zheng et al.*2024 · 114 citations* 2. **[POTATO: The Portable Text Annotation Tool](https://md.research.elamur.ai/free/en/papers/pei-2022-potato-portable-text-annotation-tool/) [Conference on Empirical Methods in Natural Language Processing (EMNLP)](https://md.research.elamur.ai/free/en/venues/emnlp/)**Jiaxin Pei, Aparna Ananthasubramaniam, Xingyao Wang, et al.*2022 · 90 citations* 3. **[Beyond Demographics: Fine-tuning Large Language Models to Predict Individuals' Subjective Text Perceptions](https://md.research.elamur.ai/free/en/papers/orlikowski-2025-beyond-demographics-fine-tuning-large/) [Annual Meeting of the Association for Computational Linguistics (ACL)](https://md.research.elamur.ai/free/en/venues/acl/)**Matthias Orlikowski, Jiaxin Pei, Paul Röttger, et al.*2025 · 22 citations* 4. **[Modeling Information Change in Science Communication with Semantically Matched Paraphrases ↗](https://aclanthology.org/2022.emnlp-main.117/) Proceedings of the 2022 Conference on Empirical Methods in Natural Language Processing · no summary yet**Dustin Wright et al.*2022 · 17 citations* ## Co-authors here 6 co-authors with a page, the most papers together first. - [David Jurgens](https://md.research.elamur.ai/free/en/authors/david-jurgens/) ×2 - [Dirk Hovy](https://md.research.elamur.ai/free/en/authors/dirk-hovy/) - [Naitian Zhou](https://md.research.elamur.ai/free/en/authors/naitian-zhou/) - [Paul Röttger](https://md.research.elamur.ai/free/en/authors/paul-rottger/) - [Philipp Cimiano](https://md.research.elamur.ai/free/en/authors/philipp-cimiano/) - [Xingyao Wang](https://md.research.elamur.ai/free/en/authors/xingyao-wang/) ## Venues Where their works here were published, the most works first, with the editions of those that have a page. - [Conference on Empirical Methods in Natural Language Processing (EMNLP)](https://md.research.elamur.ai/free/en/venues/emnlp/) ×2: [EMNLP 2022](https://md.research.elamur.ai/free/en/venues/emnlp/2022/) - [Annual Meeting of the Association for Computational Linguistics (ACL)](https://md.research.elamur.ai/free/en/venues/acl/): [ACL 2025](https://md.research.elamur.ai/free/en/venues/acl/2025/) - Findings of the Association for Computational Linguistics: EMNLP 2024 ## Cited by Papers of our library cite their works 137 times (of the 149,439 papers whose bibliographies we read); [29 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/jiaxin-pei/cited-by/).
