Application of Ontology Technology in Health Statistic Data Analysis.
Studies in health technology and informatics
Jan 1, 2017
UNLABELLED: Research Purpose: establish health management ontology for analysis of health statistic data. Proposed Methods: this paper established health management ontology based on the analysis of the concepts in China Health Statistics Yearbook, a...
Semantic Relations in Compound Nouns: Perspectives from Inter-Annotator Agreement.
Studies in health technology and informatics
Jan 1, 2017
Semantic relations have been studied for decades without yet reaching consensus on the set of these relations. However, biomedical language processing and ontologies rely on these relations, so it is important to be able to evaluate their suitability...
Aligned-Layer Text Search in Clinical Notes.
Studies in health technology and informatics
Jan 1, 2017
Search techniques in clinical text need to make fine-grained semantic distinctions, since medical terms may be negated, about someone other than the patient, or at some time other than the present. While natural language processing (NLP) approaches a...
Unsupervised Abbreviation Expansion in Clinical Narratives.
Studies in health technology and informatics
Jan 1, 2017
Clinical narratives are typically produced under time pressure, which incites the use of abbreviations and acronyms. To expand such short forms in a correct way eases text comprehension and further semantic processing. We propose a completely unsuper...
Enhanced LexSynonym Acquisition for Effective UMLS Concept Mapping.
Studies in health technology and informatics
Jan 1, 2017
Concept mapping is important in natural language processing (NLP) for bioinformatics. The UMLS Metathesaurus provides a rich synonym thesaurus and is a popular resource for concept mapping. Query expansion using synonyms for subterm substitutions is ...
Automatically Identifying Topics of Consumer Health Questions in Chinese.
Studies in health technology and informatics
Jan 1, 2017
In health question answering (QA) system development, question topic identification is crucial to understand users' information needs and further facilitate answer extraction. This paper presented a machine-learning method to automatically identify t...
Semi-Automatic Mark-Up and UMLS Annotation of Clinical Guidelines.
Studies in health technology and informatics
Jan 1, 2017
Clinical guidelines and clinical pathways are accepted and proven instruments for quality assurance and process optimization in the healthcare domain. To derive clinical pathways from clinical guidelines, the imprecise, non-formalized abstract guidel...
Light-Weighted Automatic Import of Standardized Ontologies into the Content Management System Drupal.
Studies in health technology and informatics
Jan 1, 2017
The amount of ontologies, which are utilizable for widespread domains, is growing steadily. BioPortal alone, embraces over 500 published ontologies with nearly 8 million classes. In contrast, the vast informative content of these ontologies is only d...
Expert2OWL: A Methodology for Pattern-Based Ontology Development.
Studies in health technology and informatics
Jan 1, 2017
The formalization of expert knowledge enables a broad spectrum of applications employing ontologies as underlying technology. These include eLearning, Semantic Web and expert systems. However, the manual construction of such ontologies is time-consum...
Non-Visually Performing Analytical Tasks on Statistical Charts.
Studies in health technology and informatics
Jan 1, 2017
This article proposes a natural language-based approach to accessibility of charts. Formal underpinnings are used to semantically annotate the constituent elements of a vector graphic to support accessing and modifying the content by natural language...
