Semi-supervised learning of the electronic health record for phenotype stratification.

Journal of biomedical informatics Oct 12, 2016
Patient interactions with health care providers result in entries to electronic health records (EHRs). EHRs were built for clinical and billing purposes but contain many data points about an individual. Mining these records provides opportunities to ...

Tumor reference resolution and characteristic extraction in radiology reports for liver cancer stage prediction.

Journal of biomedical informatics Oct 8, 2016
BACKGROUND: Anaphoric references occur ubiquitously in clinical narrative text. However, the problem, still very much an open challenge, is typically less aggressively focused on in clinical text domain applications. Furthermore, existing research on...

How can machine-learning methods assist in virtual screening for hyperuricemia? A healthcare machine-learning approach.

Journal of biomedical informatics Sep 19, 2016
OBJECT: Our purpose was to develop a new machine-learning approach (a virtual health check-up) toward identification of those at high risk of hyperuricemia. Applying the system to general health check-ups is expected to reduce medical costs compared ...

Automated learning of domain taxonomies from text using background knowledge.

Journal of biomedical informatics Sep 3, 2016
In this paper, we present an automated method for taxonomy learning, focusing on concept formation and hierarchical relation learning. To infer such relations, we partition the extracted concepts and group them into closely-related clusters using Hie...

Boosting backpropagation algorithm by stimulus-sampling: Application in computer-aided medical diagnosis.

Journal of biomedical informatics Aug 4, 2016
Neural networks (NNs), in general, and multi-layer perceptron (MLP), in particular, represent one of the most efficient classifiers among the machine learning (ML) algorithms. Inspired by the stimulus-sampling paradigm, it is plausible to assume that...

A pilot study of a heuristic algorithm for novel template identification from VA electronic medical record text.

Journal of biomedical informatics Aug 3, 2016
RATIONALE: Templates in text notes pose challenges for automated information extraction algorithms. We propose a method that identifies novel templates in plain text medical notes. The identification can then be used to either include or exclude temp...
