A feasibility study of answer-agnostic question generation for education

L Dugan, E Miltsakaki, S Upadhyay, E Ginsberg… - arXiv preprint arXiv …, 2022 - arxiv.org
We conduct a feasibility study into the applicability of answer-agnostic question generation
models to textbook passages. We show that a significant portion of errors in such systems …

RoFT: A tool for evaluating human detection of machine-generated text

L Dugan, D Ippolito, A Kirubarajan… - arXiv preprint arXiv …, 2020 - arxiv.org
In recent years, large neural networks for natural language generation (NLG) have made leaps
and bounds in their ability to generate fluent text. However, the tasks of evaluating quality …

Real or fake text?: Investigating human ability to detect boundaries between human-written and machine-generated text

L Dugan, D Ippolito, A Kirubarajan, S Shi… - Proceedings of the …, 2023 - ojs.aaai.org
As text generated by large language models proliferates, it becomes vital to understand
how humans engage with such text, and whether or not they are able to detect when the text …

Mechanospray ionization MS of proteins including in the folded state and polymers

LD Dugan, ME Bier - Journal of the American Society for Mass …, 2022 - ACS Publications
Mechanospray ionization (MoSI) is a technique that produces ions directly from solution-like
electrospray ionization (ESI) but without the need of a high voltage. In MoSI, mechanical …

Exploring the curious case of code prompts

L Zhang, L Dugan, H Xu, C Callison-Burch - arXiv preprint arXiv …, 2023 - arxiv.org
Recent work has shown that prompting language models with code-like representations of
natural language leads to performance improvements on structured reasoning tasks. However…

RAID: A Shared Benchmark for Robust Evaluation of Machine-Generated Text Detectors

L Dugan, A Hwang, F Trhlik, JM Ludan, A Zhu… - arXiv preprint arXiv …, 2024 - arxiv.org
Many commercial and open-source models claim to detect machine-generated text with
very high accuracy (99\% or higher). However, very few of these detectors are evaluated on …

FanOutQA: A Multi-Hop, Multi-Document Question Answering Benchmark for Large Language Models

A Zhu, A Hwang, L Dugan… - Proceedings of the 62nd …, 2024 - aclanthology.org
One type of question that is commonly found in day-to-day scenarios is “fan-out” questions,
complex multi-hop, multi-document reasoning questions that require finding information …

Watching paint dry: organic vapor emissions from architectural coatings and their impact on secondary organic aerosol formation

R Tanzer-Gruener, PE Rajan, LD Dugan… - Environmental …, 2022 - ACS Publications
Emissions from volatile chemical products (VCPs) are emerging as a major source of
anthropogenic secondary organic aerosol (SOA) precursors. Paints and coatings are an important …

Enhancing human summaries for question-answer generation in education

H Gonzalez, L Dugan, E Miltsakaki, Z Cui… - Proceedings of the …, 2023 - aclanthology.org
We address the problem of generating high-quality question-answer pairs for educational
materials. Previous work on this problem showed that using summaries as input improves the …

Fanoutqa: Multi-hop, multi-document question answering for large language models

A Zhu, A Hwang, L Dugan, C Callison-Burch - arXiv preprint arXiv …, 2024 - arxiv.org
One type of question that is commonly found in day-to-day scenarios is ``fan-out'' questions,
complex multi-hop, multi-document reasoning questions that require finding information …
