Bilingual term alignment from comparable corpora in English discharge summary and Chinese discharge summary.
BMC bioinformatics
May 9, 2015
BACKGROUND: Electronic medical record (EMR) systems have become widely used throughout the world to improve the quality of healthcare and the efficiency of hospital services. A bilingual medical lexicon of Chinese and English is needed to meet the de...
A multilingual gold-standard corpus for biomedical concept recognition: the Mantra GSC.
Journal of the American Medical Informatics Association : JAMIA
May 6, 2015
OBJECTIVE: To create a multilingual gold-standard corpus for biomedical concept recognition.
Toward high-throughput phenotyping: unbiased automated feature extraction and selection from knowledge sources.
Journal of the American Medical Informatics Association : JAMIA
Apr 29, 2015
OBJECTIVE: Analysis of narrative (text) data from electronic health records (EHRs) can improve population-scale phenotyping for clinical and genetic research. Currently, selection of text features for phenotyping algorithms is slow and laborious, req...
Development of phenotype algorithms using electronic medical records and incorporating natural language processing.
BMJ (Clinical research ed.)
Apr 24, 2015
Electronic medical records are emerging as a major source of data for clinical and translational research studies, although phenotypes of interest need to be accurately defined first. This article provides an overview of how to develop a phenotype al...
Evaluating a pivot-based approach for bilingual lexicon extraction.
Computational intelligence and neuroscience
Apr 23, 2015
A pivot-based approach for bilingual lexicon extraction is based on the similarity of context vectors represented by words in a pivot language like English. In this paper, in order to show validity and usability of the pivot-based approach, we evalua...
Self-training in significance space of support vectors for imbalanced biomedical event data.
BMC bioinformatics
Apr 23, 2015
BACKGROUND: Pairwise relationships extracted from biomedical literature are insufficient in formulating biomolecular interactions. Extraction of complex relations (namely, biomedical events) has become the main focus of the text-mining community. How...
Automated methods for the summarization of electronic health records.
Journal of the American Medical Informatics Association : JAMIA
Apr 15, 2015
OBJECTIVES: This review examines work on automated summarization of electronic health record (EHR) data and in particular, individual patient record summarization. We organize the published research and highlight methodological challenges in the area...
Increasing the efficiency of trial-patient matching: automated clinical trial eligibility pre-screening for pediatric oncology patients.
BMC medical informatics and decision making
Apr 14, 2015
BACKGROUND: Manual eligibility screening (ES) for a clinical trial typically requires a labor-intensive review of patient records that utilizes many resources. Leveraging state-of-the-art natural language processing (NLP) and information extraction (...
Encoding sequential information in semantic space models: comparing holographic reduced representation and random permutation.
Computational intelligence and neuroscience
Apr 7, 2015
Circular convolution and random permutation have each been proposed as neurally plausible binding operators capable of encoding sequential information in semantic memory. We perform several controlled comparisons of circular convolution and random pe...
An Evaluation of Patient Safety Event Report Categories Using Unsupervised Topic Modeling.
Methods of information in medicine
Apr 2, 2015
OBJECTIVE: Patient safety event data repositories have the potential to dramatically improve safety if analyzed and leveraged appropriately. These safety event reports often consist of both structured data, such as general event type categories, and ...
