Evaluation of AI Ethics Tools in Language Models: A Developers' Perspective Case Stud

TL;DR

This paper evaluates four AI Ethics Tools for language models in Portuguese, highlighting their strengths and limitations from developers' perspectives through literature review and interviews.

Contribution

It introduces a methodology for assessing AIETs' effectiveness in practice, focusing on language models and developer insights.

Findings

AIETs guide general ethical considerations but miss language-specific nuances.

They do not effectively identify potential negative impacts for Portuguese language models.

Developers find AIETs useful but limited in addressing unique language model issues.

Abstract

In Artificial Intelligence (AI), language models have gained significant importance due to the widespread adoption of systems capable of simulating realistic conversations with humans through text generation. Because of their impact on society, developing and deploying these language models must be done responsibly, with attention to their negative impacts and possible harms. In this scenario, the number of AI Ethics Tools (AIETs) publications has recently increased. These AIETs are designed to help developers, companies, governments, and other stakeholders establish trust, transparency, and responsibility with their technologies by bringing accepted values to guide AI's design, development, and use stages. However, many AIETs lack good documentation, examples of use, and proof of their effectiveness in practice. This paper presents a methodology for evaluating AIETs in language models. Our approach involved an extensive literature survey on 213 AIETs, and after applying inclusion and exclusion criteria, we selected four AIETs: Model Cards, ALTAI, FactSheets, and Harms Modeling. For evaluation, we applied AIETs to language models developed for the Portuguese language, conducting 35 hours of interviews with their developers. The evaluation considered the developers' perspective on the AIETs' use and quality in helping to identify ethical considerations about their model. The results suggest that the applied AIETs serve as a guide for formulating general ethical considerations about language models. However, we note that they do not address unique aspects of these models, such as idiomatic expressions. Additionally, these AIETs did not help to identify potential negative impacts of models for the Portuguese language.
