How essential are unstructured clinical narratives and information fusion to clinical trial recruitment?

no code implementations13 Feb 2015 Preethi Raghavan, James L. Chen, Eric Fosler-Lussier, Albert M. Lai

We perform an empirical study to validate the argument and show that structured data alone is insufficient in resolving eligibility criteria for recruiting patients onto clinical trials for chronic lymphocytic leukemia (CLL) and prostate cancer.

Annotating Electronic Medical Records for Question Answering

no code implementations17 May 2018 Preethi Raghavan, Siddharth Patwardhan, Jennifer J. Liang, Murthy V. Devarakonda

Over the course of 11 months, 11 medical students followed our annotation methodology, resulting in a question answering dataset of 5696 questions over 71 patient records, of which 1747 questions have corresponding answers generated by the medical students.

Understanding BLOOM: An empirical study on diverse NLP tasks

no code implementations27 Nov 2022 Parag Pravin Dakle, SaiKrishna Rallabandi, Preethi Raghavan

We view the landscape of large language models (LLMs) through the lens of the recently released BLOOM model to understand the performance of BLOOM and other decoder-only LLMs compared to BERT-style encoder-only models.

BlendSQL: A Scalable Dialect for Unifying Hybrid Question Answering in Relational Algebra

1 code implementation27 Feb 2024 Parker Glenn, Parag Pravin Dakle, Liang Wang, Preethi Raghavan

Many existing end-to-end systems for hybrid question answering tasks can often be boiled down to a "prompt-and-pray" paradigm, where the user has limited control and insight into the intermediate reasoning steps used to achieve the final result.
