Expansion of the Hierarchical Terminology Auditing Framework Through Usage of Levenshtein Distance-Based Criterion.
Studies in health technology and informatics
Jan 1, 2016
We continue our previous work of creating and improving a framework for detecting the differences between hierarchical terminologies and suggesting ways to connect them, which is implemented in an automated tool.
Preliminary Analysis of Difficulty of Importing Pattern-Based Concepts into the National Cancer Institute Thesaurus.
Studies in health technology and informatics
Jan 1, 2016
Maintenance of biomedical ontologies is difficult. We have developed a pattern-based method for dealing with the problem of identifying missing concepts in the National Cancer Institute thesaurus (NCIt). Specifically, we are mining patterns connectin...
Natural Language Processing Technologies in Radiology Research and Clinical Applications.
Radiographics : a review publication of the Radiological Society of North America, Inc
Jan 1, 2016
The migration of imaging reports to electronic medical record systems holds great potential in terms of advancing radiology research and practice by leveraging the large volume of data continuously being updated, integrated, and shared. However, ther...
[Big data, medical language and biomedical terminology systems].
Bundesgesundheitsblatt, Gesundheitsforschung, Gesundheitsschutz
Aug 1, 2015
A variety of rich terminology systems, such as thesauri, classifications, nomenclatures and ontologies support information and knowledge processing in health care and biomedical research. Nevertheless, human language, manifested as individually writt...
Exploiting ontology graph for predicting sparsely annotated gene function.
Bioinformatics (Oxford, England)
Jun 15, 2015
MOTIVATION: Systematically predicting gene (or protein) function based on molecular interaction networks has become an important tool in refining and enhancing the existing annotation catalogs, such as the Gene Ontology (GO) database. However, functi...
Searches for randomized controlled trials of drugs in MEDLINE and EMBASE using only generic drug names compared with searches applied in current practice in systematic reviews.
Research synthesis methods
Jun 1, 2015
BACKGROUND: It is unclear which terms should be included in bibliographic searches for randomized controlled trials (RCTs) of drugs, and identifying relevant drug terms can be extremely laborious. The aim of our analysis was to determine whether a bi...
Learning multiple distributed prototypes of semantic categories for named entity recognition.
International journal of data mining and bioinformatics
Jan 1, 2015
The scarcity of large labelled datasets comprising clinical text that can be exploited within the paradigm of supervised machine learning creates barriers for the secondary use of data from electronic health records. It is therefore important to deve...
Facilitating Full-text Access to Biomedical Literature Using Open Access Resources.
Studies in health technology and informatics
Jan 1, 2015
Open access (OA) resources and local libraries often have their own literature databases, especially in the field of biomedicine. We have developed a method of linking a local library to a biomedical OA resource facilitating researchers' full-text ar...
Representation of Biomedical Expertise in Ontologies: a Case Study about Knowledge Acquisition on HTLV viruses and their clinical manifestations.
Studies in health technology and informatics
Jan 1, 2015
In this paper, we introduce a set of methodological steps for knowledge acquisition applied to the organization of biomedical information through ontologies. Those steps are tested in a real case involving Human T Cell Lymphotropic Virus (HTLV), whic...
A Pilot Ontology for Healthcare Quality Indicators.
Studies in health technology and informatics
Jan 1, 2015
Computerisation of quality indicators for the English National Health Service currently relies primarily on queries and clinical coding, with little use of ontologies. We created a searchable ontology for a diverse set of healthcare quality indicator...
