Ontoserver: a syndicated terminology server.
Journal of biomedical semantics
Sep 17, 2018
BACKGROUND: Even though several high-quality clinical terminologies, such as SNOMED CT and LOINC, are readily available, uptake in clinical systems has been slow and many continue to capture information in plain text or using custom terminologies. Th...
Supporting biomedical ontology evolution by identifying outdated concepts and the required type of change.
Journal of biomedical informatics
Sep 8, 2018
The consistent evolution of ontologies is a major challenge for systems using semantically enriched data, for example, for annotating, indexing, or reasoning. The biomedical domain is a typical example where ontologies, expressed with different forma...
SNOMED CT standard ontology based on the ontology for general medical science.
BMC medical informatics and decision making
Aug 31, 2018
BACKGROUND: Systematized Nomenclature of Medicine-Clinical Terms (SNOMED CT, hereafter abbreviated SCT) is a comprehensive medical terminology used for standardizing the storage, retrieval, and exchange of electronic health data. Some efforts have be...
From lexical regularities to axiomatic patterns for the quality assurance of biomedical terminologies and ontologies.
Journal of biomedical informatics
Jun 14, 2018
Ontologies and terminologies have been identified as key resources for the achievement of semantic interoperability in biomedical domains. The development of ontologies is performed as a joint work by domain experts and knowledge engineers. The maint...
Complex overlapping concepts: An effective auditing methodology for families of similarly structured BioPortal ontologies.
Journal of biomedical informatics
May 28, 2018
In previous research, we have demonstrated for a number of ontologies that structurally complex concepts (for different definitions of "complex") in an ontology are more likely to exhibit errors than other concepts. Thus, such complex concepts often ...
An efficient, large-scale, non-lattice-detection algorithm for exhaustive structural auditing of biomedical ontologies.
Journal of biomedical informatics
Mar 13, 2018
One of the basic challenges in developing structural methods for systematic audition on the quality of biomedical ontologies is the computational cost usually involved in exhaustive sub-graph analysis. We introduce ANT-LCA, a new algorithm for comput...
CUILESS2016: a clinical corpus applying compositional normalization of text mentions.
Journal of biomedical semantics
Jan 10, 2018
BACKGROUND: Traditionally text mention normalization corpora have normalized concepts to single ontology identifiers ("pre-coordinated concepts"). Less frequently, normalization corpora have used concepts with multiple identifiers ("post-coordinated ...
Auditing SNOMED CT hierarchical relations based on lexical features of concepts in non-lattice subgraphs.
Journal of biomedical informatics
Dec 20, 2017
OBJECTIVE: We introduce a structural-lexical approach for auditing SNOMED CT using a combination of non-lattice subgraphs of the underlying hierarchical relations and enriched lexical attributes of fully specified concept names. Our goal is to develo...
An Extended SNOMED CT Concept Model for Observations in Molecular Genetics.
AMIA ... Annual Symposium proceedings. AMIA Symposium
Feb 10, 2017
Molecular genetics laboratory reports are multiplying and increasingly of clinical importance in diagnosis and treatment of cancer, infectious disease and managing of public health. Little of this data is structured or maintained in the EHR in format...
Evaluating semantic similarity between Chinese biomedical terms through multiple ontologies with score normalization: An initial study.
Journal of biomedical informatics
Nov 1, 2016
BACKGROUND: Semantic similarity estimation significantly promotes the understanding of natural language resources and supports medical decision making. Previous studies have investigated semantic similarity and relatedness estimation between biomedic...
