OBJECTIVES This study evaluates the accuracy and portability of a natural language processing (NLP) tool for extracting clinical findings of influenza from clinical notes across two large healthcare systems. Effectiveness is evaluated on how well NLP supports downstream influenza case-detection for disease surveillance. METHODS We independently developed two NLP parsers, one at Intermountain Healthcare (IH) in Utah and the other at University of Pittsburgh Medical Center (UPMC) using local…

Detecting Social and Behavioral Determinants of Health with Structured and Free-Text Clinical Data
It is suggested that combining clinical free-text notes and structured data provide the best approach in classifying patient SBDH status, which is most challenging among S BDH with low prevalence and high lexical diversity.
Transferability of neural network clinical deidentification systems
This article investigates the transferability of a state-of-the-art neural clinical deidentification system, NeuroNER, across a variety of datasets, when it is modified architecturally for domain generalization andWhen it is trained strategically for domain transfer.

Transferability of Neural Network-based De-identification Systems
The investigated transferability of neural network-based de-identification sys-tems with and without domain generalization found transferability from a single external source gave inconsistent re-sults, and external sources were useful even in cases where in-domain training data were available.


Evaluating Natural Language Processing Applications Applied to Outbreak and Disease Surveillance
Much of the pre-existing electronic data that could be harnessed for early outbreak detection is in free-text format. Natural language processing (NLP) techniques may be useful to biosurveillance by
Research and applications: Influenza detection from emergency department reports using natural language processing and Bayesian network classifiers
Using a three-component evaluation method, this study demonstrated how one could elucidate the relative contributions of components under an integrated framework and encourages researchers to improve NLP accuracy, use a machine-parameterized classifier, and apply feature selection methods.
Natural Language Processing : Can it Help Detect Cases and Characterize Outbreaks ?
An error analysis of an NL Pbased ILI case detection application previously applied to the VA textual clinical records is described, which found that free-text processing of clinical no tes brings information about disease symptoms that complements and enhances detection.
Comparison of Natural Language Processing Biosurveillance Methods for Identifying Influenza From Encounter Notes
Because case-defining signs and symptoms of influenza are commonly available in health records, the investigators believe that the national strategy for biosurveillance should be changed to incorporate data from the whole health record.
Overcoming barriers to NLP for clinical text: the role of shared tasks and the need for additional creative solutions
This issue of JAMIA focuses on natural language processing (NLP) techniques for clinical-text information extraction and shared tasks like the i2b2/VA Challenge, a shared-task challenge co-sponsored by the Veteran's Administration for the last 2 years.
Natural Language Processing for Biosurveillance
A modest but solid foundation has been laid for natural Language processing of clinical text for the purpose of biosurveillance, with the main focus being on chief complaints.
