Neural Temporal Relation Extraction

no code implementations EACL 2017 Dmitriy Dligach, Timothy Miller, Chen Lin, Steven Bethard, Guergana Savova

We experiment with neural architectures for temporal relation extraction and establish a new state-of-the-art for several scenarios.

SemEval-2017 Task 12: Clinical TempEval

no code implementations SEMEVAL 2017 Steven Bethard, Guergana Savova, Martha Palmer, James Pustejovsky

Clinical TempEval 2017 aimed to answer the question: how well do systems trained on annotated timelines for one medical condition (colon cancer) perform in predicting timelines on another medical condition (brain cancer)?

Spotting Spurious Data with Neural Networks

no code implementations NAACL 2018 Hadi Amiri, Timothy Miller, Guergana Savova

Automatic identification of spurious instances (those with potentially wrong labels in datasets) can improve the quality of existing language resources, especially when annotations are obtained through crowdsourcing or automatically generated based on coded rankings.

Cross-document coreference: An approach to capturing coreference without context

no code implementations WS 2019 Kristin Wright-Bettner, Martha Palmer, Guergana Savova, Piet de Groen, Timothy Miller

This paper discusses a cross-document coreference annotation schema that was developed to further automatic extraction of timelines in the clinical domain.

Diagnosis Prevalence vs. Efficacy in Machine-learning Based Diagnostic Decision Support

no code implementations24 Jun 2020 Gil Alon, Elizabeth Chen, Guergana Savova, Carsten Eickhoff

Scores fell from 0. 28 for the 50 most prevalent ICD-9-CM codes to 0. 03 for the 1000 most prevalent ICD-9-CM codes.

Mining Misdiagnosis Patterns from Biomedical Literature

1 code implementation24 Jun 2020 Cindy Li, Elizabeth Chen, Guergana Savova, Hamish Fraser, Carsten Eickhoff

Diagnostic errors can pose a serious threat to patient safety, leading to serious harm and even death.

Measuring Pointwise $\mathcal{V}$-Usable Information In-Context-ly

1 code implementation18 Oct 2023 Sheng Lu, Shan Chen, Yingya Li, Danielle Bitterman, Guergana Savova, Iryna Gurevych

In-context learning (ICL) is a new learning paradigm that has gained popularity along with the development of large language models.

EntityBERT: Entity-centric Masking Strategy for Model Pretraining for the Clinical Domain

no code implementations NAACL (BioNLP) 2021 Chen Lin, Timothy Miller, Dmitriy Dligach, Steven Bethard, Guergana Savova

We propose a methodology to produce a model focused on the clinical domain: continued pretraining of a model with a broad representation of biomedical terminology (PubMedBERT) on a clinical corpus along with a novel entity-centric masking strategy to infuse domain knowledge in the learning process.

Exploring Text Representations for Generative Temporal Relation Extraction

no code implementations NAACL (ClinicalNLP) 2022 Dmitriy Dligach, Steven Bethard, Timothy Miller, Guergana Savova

Sequence-to-sequence models are appealing because they allow both encoder and decoder to be shared across many tasks by formulating those tasks as text-to-text problems.

Ensemble-based Fine-Tuning Strategy for Temporal Relation Extraction from the Clinical Narrative

no code implementations NAACL (ClinicalNLP) 2022 Lijing Wang, Timothy Miller, Steven Bethard, Guergana Savova

In this paper, we investigate ensemble methods for fine-tuning transformer-based pretrained models for clinical natural language processing tasks, specifically temporal relation extraction from the clinical narrative.
