A transformation-based method for auditing the IS-A hierarchy of biomedical terminologies in the Unified Medical Language System.
Journal of the American Medical Informatics Association : JAMIA
Oct 1, 2020
OBJECTIVE: The Unified Medical Language System (UMLS) integrates various source terminologies to support interoperability between biomedical information systems. In this article, we introduce a novel transformation-based auditing method that leverage...
Unified Medical Language System resources improve sieve-based generation and Bidirectional Encoder Representations from Transformers (BERT)-based ranking for concept normalization.
Journal of the American Medical Informatics Association : JAMIA
Oct 1, 2020
OBJECTIVE: Concept normalization, the task of linking phrases in text to concepts in an ontology, is useful for many downstream tasks including relation extraction, information retrieval, etc. We present a generate-and-rank concept normalization syst...
Can Unified Medical Language System-based semantic representation improve automated identification of patient safety incident reports by type and severity?
Journal of the American Medical Informatics Association : JAMIA
Oct 1, 2020
OBJECTIVE: The study sought to evaluate the feasibility of using Unified Medical Language System (UMLS) semantic features for automated identification of reports about patient safety incidents by type and severity.
The Impact of Specialized Corpora for Word Embeddings in Natural Langage Understanding.
Studies in health technology and informatics
Jun 16, 2020
Recent studies in the biomedical domain suggest that learning statistical word representations (static or contextualized word embeddings) on large corpora of specialized data improve the results on downstream natural language processing (NLP) tasks. ...
Parallel Sentence Alignment from Biomedical Comparable Corpora.
Studies in health technology and informatics
Jun 16, 2020
Parallel sentences provide semantically similar information which can vary on a given dimension, such as language or register. Parallel sentences with register variation (like expert and non-expert documents) can be exploited for the automatic text s...
A Semi-Automated Approach for Multilingual Terminology Matching: Mapping the French Version of the ICD-10 to the ICD-10 CM.
Studies in health technology and informatics
Jun 16, 2020
The aim of this study was to develop a simple method to map the French International Statistical Classification of Diseases and Related Health Problems, 10th revision (ICD-10) with the International Classification of Diseases, 10th Revision, Clinical...
iDISK: the integrated DIetary Supplements Knowledge base.
Journal of the American Medical Informatics Association : JAMIA
Apr 1, 2020
OBJECTIVE: To build a knowledge base of dietary supplement (DS) information, called the integrated DIetary Supplement Knowledge base (iDISK), which integrates and standardizes DS-related information from 4 existing resources.
Consumer health information and question answering: helping consumers find answers to their health-related information needs.
Journal of the American Medical Informatics Association : JAMIA
Feb 1, 2020
OBJECTIVE: Consumers increasingly turn to the internet in search of health-related information; and they want their questions answered with short and precise passages, rather than needing to analyze lists of relevant documents returned by search engi...
Extracting medications and associated adverse drug events using a natural language processing system combining knowledge base and deep learning.
Journal of the American Medical Informatics Association : JAMIA
Jan 1, 2020
OBJECTIVE: Detecting adverse drug events (ADEs) and medications related information in clinical notes is important for both hospital medical care and medical research. We describe our clinical natural language processing (NLP) system to automatically...
High-throughput multimodal automated phenotyping (MAP) with application to PheWAS.
Journal of the American Medical Informatics Association : JAMIA
Nov 1, 2019
OBJECTIVE: Electronic health records linked with biorepositories are a powerful platform for translational studies. A major bottleneck exists in the ability to phenotype patients accurately and efficiently. The objective of this study was to develop ...
