Cohort Discovery Query Optimization via Computable Controlled Vocabulary Versioning.
Studies in health technology and informatics
Jan 1, 2015
Self-service cohort discovery tools strive to provide intuitive interfaces to large Clinical Data Warehouses that contain extensive historic information. In those tools, controlled vocabulary (e.g., ICD-9-CM, CPT) coded clinical information is often ...
Development of Markup Language for Medical Record Charting: A Charting Language.
Studies in health technology and informatics
Jan 1, 2015
Nowadays a lot of trials for collecting electronic medical records (EMRs) exist. However, structuring data format for EMR is an especially labour-intensive task for practitioners. Here we propose a new mark-up language for medical record charting (ca...
An efficient algorithm for updating regular expression indexes in RDF databases.
International journal of data mining and bioinformatics
Jan 1, 2015
The Resource Description Framework (RDF) is widely used for sharing biomedical data, such as gene ontology or the online protein database UniProt. SPARQL is a native query language for RDF, featuring regular expressions in queries for which exact val...
Managing changes in distributed biomedical ontologies using hierarchical distributed graph transformation.
International journal of data mining and bioinformatics
Jan 1, 2015
The issue of ontology evolution and change management is inadequately addressed by available tools and algorithms, mostly due to the lack of suitable knowledge representation formalisms to deal with temporal abstract notations and the overreliance on...
