Automatic prediction of coronary artery disease from clinical narratives.
Journal of biomedical informatics
Jun 27, 2017
Coronary Artery Disease (CAD) is not only the most common form of heart disease, but also the leading cause of death in both men and women (Coronary Artery Disease: MedlinePlus, 2015). We present a system that is able to automatically predict whether...
An empirical analysis of ontology reuse in BioPortal.
Journal of biomedical informatics
Jun 2, 2017
Biomedical ontologies often reuse content (i.e., classes and properties) from other ontologies. Content reuse enables a consistent representation of a domain and reusing content can save an ontology author significant time and effort. Prior studies h...
Tool-supported Interactive Correction and Semantic Annotation of Narrative Clinical Reports.
Methods of information in medicine
Apr 28, 2017
OBJECTIVES: Our main objective is to design a method of, and supporting software for, interactive correction and semantic annotation of narrative clinical reports, which would allow for their easier and less erroneous processing outside their origina...
Relating Complexity and Error Rates of Ontology Concepts. More Complex NCIt Concepts Have More Errors.
Methods of information in medicine
Feb 28, 2017
OBJECTIVES: Ontologies are knowledge structures that lend support to many health-information systems. A study is carried out to assess the quality of ontological concepts based on a measure of their complexity. The results show a relation between com...
Structuring Legacy Pathology Reports by openEHR Archetypes to Enable Semantic Querying.
Methods of information in medicine
Feb 28, 2017
BACKGROUND: Clinical information is often stored as free text, e.g. in discharge summaries or pathology reports. These documents are semi-structured using section headers, numbered lists, items and classification strings. However, it is still challen...
Mapping Phenotypic Information in Heterogeneous Textual Sources to a Domain-Specific Terminological Resource.
PloS one
Sep 19, 2016
Biomedical literature articles and narrative content from Electronic Health Records (EHRs) both constitute rich sources of disease-phenotype information. Phenotype concepts may be mentioned in text in multiple ways, using phrases with a variety of st...
OntoBrowser: a collaborative tool for curation of ontologies by subject matter experts.
Bioinformatics (Oxford, England)
Sep 6, 2016
UNLABELLED: The lack of controlled terminology and ontology usage leads to incomplete search results and poor interoperability between databases. One of the major underlying challenges of data integration is curating data to adhere to controlled term...
Knowledge Discovery from Biomedical Ontologies in Cross Domains.
PloS one
Aug 22, 2016
In recent years, there is an increasing demand for sharing and integration of medical data in biomedical research. In order to improve a health care system, it is required to support the integration of data by facilitating semantic interoperability s...
MeSH-Informed Enrichment Analysis and MeSH-Guided Semantic Similarity Among Functional Terms and Gene Products in Chicken.
G3 (Bethesda, Md.)
Aug 9, 2016
Biomedical vocabularies and ontologies aid in recapitulating biological knowledge. The annotation of gene products is mainly accelerated by Gene Ontology (GO), and more recently by Medical Subject Headings (MeSH). Here, we report a suite of MeSH pack...
TopoICSim: a new semantic similarity measure based on gene ontology.
BMC bioinformatics
Jul 29, 2016
BACKGROUND: The Gene Ontology (GO) is a dynamic, controlled vocabulary that describes the cellular function of genes and proteins according to tree major categories: biological process, molecular function and cellular component. It has become widely ...
