MIMDE: Exploring the Use of Synthetic vs Human Data for Evaluating Multi-Insight Multi-Document Extraction Tasks

no code implementations29 Nov 2024 John Francis, Saba Esnaashari, Anton Poletaev, Sukankana Chakraborty, Youmna Hashem, Jonathan Bright

We develop an evaluation framework for MIMDE and introduce a novel set of complementary human and synthetic datasets to examine the potential of synthetic data for LLM evaluation.

Evidence of a log scaling law for political persuasion with large language models

1 code implementation20 Jun 2024 Kobi Hackenburg, Ben M. Tappin, Paul Röttger, Scott Hale, Jonathan Bright, Helen Margetts

Large language models can now generate political messages as persuasive as those written by humans, raising concerns about how far this persuasiveness may continue to increase with model size.

AI for bureaucratic productivity: Measuring the potential of AI to help automate 143 million UK government transactions

no code implementations18 Mar 2024 Vincent J. Straub, Youmna Hashem, Jonathan Bright, Satyam Bhagwanani, Deborah Morgan, John Francis, Saba Esnaashari, Helen Margetts

We estimate that UK central government conducts approximately one billion citizen-facing transactions per year in the provision of around 400 services, of which approximately 143 million are complex repetitive transactions.

Cheap Learning: Maximising Performance of Language Models for Social Data Science Using Minimal Data

1 code implementation22 Jan 2024 Leonardo Castro-Gonzalez, Yi-Ling Chung, Hannak Rose Kirk, John Francis, Angus R. Williams, Pica Johansson, Jonathan Bright

These `cheaper' learning techniques hold significant potential for the social sciences, where development of large labelled training datasets is often a significant practical impediment to the use of machine learning for analytical tasks.

DoDo Learning: DOmain-DemOgraphic Transfer in Language Models for Detecting Abuse Targeted at Public Figures

1 code implementation31 Jul 2023 Angus R. Williams, Hannah Rose Kirk, Liam Burke, Yi-Ling Chung, Ivan Debono, Pica Johansson, Francesca Stevens, Jonathan Bright, Scott A. Hale

We find that (i) small amounts of diverse data are hugely beneficial to generalisation and model adaptation; (ii) models transfer more easily across demographics but models trained on cross-domain data are more generalisable; (iii) some groups contribute more to generalisability than others; and (iv) dataset similarity is a signal of transferability.

Understanding Counterspeech for Online Harm Mitigation

no code implementations1 Jul 2023 Yi-Ling Chung, Gavin Abercrombie, Florence Enock, Jonathan Bright, Verena Rieser

Counterspeech offers direct rebuttals to hateful speech by challenging perpetrators of hate and showing support to targets of abuse.

'Team-in-the-loop': Ostrom's IAD framework 'rules in use' to map and measure contextual impacts of AI

no code implementations24 Mar 2023 Deborah Morgan, Youmna Hashem, John Francis, Saba Esnaashari, Vincent J. Straub, Jonathan Bright

This article explores how the 'rules in use' from Ostrom's Institutional Analysis and Development Framework (IAD) can be developed as a context analysis approach for AI.

A multidomain relational framework to guide institutional AI research and adoption

no code implementations17 Mar 2023 Vincent J. Straub, Deborah Morgan, Youmna Hashem, John Francis, Saba Esnaashari, Jonathan Bright

Calls for new metrics, technical standards and governance mechanisms to guide the adoption of Artificial Intelligence (AI) in institutions and public administration are now commonplace.

Artificial intelligence in government: Concepts, standards, and a unified framework

1 code implementation31 Oct 2022 Vincent J. Straub, Deborah Morgan, Jonathan Bright, Helen Margetts

Recent advances in artificial intelligence (AI), especially in generative language modelling, hold the promise of transforming government.
