Proceedings of the First Workshop on Patient-Oriented Language Processing (CL4Health) @ LREC-COLING 2024

In this paper, we explore consumer health question (CHQ) reformulation, focusing on enhancing the quality of reformation of questions without considering interest shifts. Our study introduces the use of the NIH GARD website as a gold standard dataset for this specific task, emphasizing its relevance and applicability. Additionally, we developed other datasets consisting of related questions scraped from Google, Bing, and Yahoo. We augmented, evaluated and analyzed the various datasets, demonstrating that the reformulation task closely resembles the question entailment generation task. Our approach, which integrates the Focus and Type of consumer inquiries, represents a significant advancement in the field of question reformulation. We provide a comprehensive analysis of different methodologies, offering insights into the development of more effective and user-centric AI systems for consumer health support.

MNLP at FinCausal2022: Nested NER with a Generative Model
Jooyeon Lee | Luan Huy Pham | Özlem Uzuner
Proceedings of the 4th Financial Narrative Processing Workshop @LREC2022

This paper describes work performed for the FinCasual 2022 Shared Task “Financial Document Causality Detection” (FinCausal 2022). As the name implies, the task involves extraction of casual and consequential elements from financial text. Our approach focuses employing Nested NER using the Text-to-Text Transformer (T5) generative transformer models while applying different combinations of datasets and tagging methods. Our system reports accuracy of 79% in Exact Match comparison and F-measure score of 92% token level measurement.
