Differential Bias: On the Perceptibility of Stance Imbalance in Argumentation (2022.findings-aacl)
Copied to clipboard
| Challenge: | a theoretical model of bias classification is not feasible because of complexity of interpreting language phenomena. |
| Approach: | They propose to analyze whether a text is biased based on an algorithmic analysis . they propose to use a model to determine whether x is more biased than y . |
| Outcome: | a crowdsourcing study shows that differences in stance bias are perceptible when (light) support is provided through training or visual aids. |
EdTec-QBuilder: A Semantic Retrieval Tool for Assembling Vocational Training Exams in German Language (2024.naacl-demo)
Copied to clipboard
| Challenge: | Existing methods to gather test items from validated item databases are under-researched, but there is little research on assembling exam items from a database of valid items. |
| Approach: | They propose to use semantic search to assist vocational educators in assembling exam forms by using eight retrieval strategies and 25 popular sentence similarity models. |
| Outcome: | The proposed tool is based on eight retrieval strategies and 25 popular pre-trained sentence similarity models. |
Mitigating Bias in Item Retrieval for Enhancing Exam Assembly in Vocational Education Services (2025.naacl-industry)
Copied to clipboard
| Challenge: | Despite the practical importance of exam assembly, few methods exist to support educators during manual item retrieval for exam assembly tasks. |
| Approach: | They propose a mixed-integer programming re-ranking approach to improve relevance while mitigating bias on an industry-grade exam assembly platform. |
| Outcome: | The proposed approach improves relevance and reduces bias by 17% when compared to other methods on a real-world exam assembly platform. |
