Polynomial-Time Reasoning Support for Design and Maintenance of Large-Scale Biomedical Ontologies
… empirical evaluation on several large-scale biomedical ontologies.

GoPubMed: Ontology-based literature search for the life sciences
Background: Most of our biomedical knowledge is only accessible through texts. The biomedical literature grows exponentially and PubMed comprises over 18.000.000 literature abstracts. Recently much effort has been put into the creation of biomedical ontologies which capture biomedical facts. The …

Designing novel abstraction networks for ontology summarization and quality assurance
Biomedical ontologies are complex knowledge representation systems. Biomedical ontologies support interdisciplinary research, interoperability of medical systems, and Electronic Healthcare Record (EHR) encoding. Ontologies represent knowledge using concepts (entities) linked by relationships. …

Using structural and semantic methodologies to enhance biomedical terminologies
Biomedical terminologies and ontologies underlie various Health Information Systems (HISs), Electronic Health Record (EHR) Systems, Health Information Exchanges (HIEs) and health administrative systems. Moreover, the proliferation of interdisciplinary research efforts in the biomedical field is …

A medical ultrasound reporting system based on domain ontology
… from the sample reports were mapped to existing biomedical ontologies. It is anticipated that a standardised report based on domain ontology will improve the quality of ultrasound reports and encourage its implementation.

Development of an ontology of animals in context within the OBO Foundry framework from a SNOMED-CT extension and subset
… and role in production systems such as farms. Ontologies are created and used for defining, organizing and classifying information in a domain to enable learning and sharing of information. This work develops an ontology of animal classes that form the basis for communication of animal …

Extensions of SNOMED taxonomy abstraction networks supporting auditing and complexity analysis
… widely used as a standard terminology in various biomedical domains. The enhancement of the quality of SNOMED contributes to the improvement of the medical systems that it supports. In previous work, the Structural Analysis of Biomedical Ontologies Center (SABOC) team has defined the partial-area …

Semantic Frameworks for Document and Ontology Clustering
… in many fields, is one way to facilitate this. Ontologies can also help in addressing the problem of finding related entities, including research publications. However, the development of new methods of clustering has focused mainly on the algorithm per se, with relatively less emphasis on …

Ontology-based document representation for biomedical information retrieval
… a considerable part of their time searching the biomedical literature. This avoids expensive experiment duplications in wet labs, and provides inspiration for new hypotheses. Unfortunately, the fast growth of biological information, in the form of free-text, has led to a lack of standard in the …

Cloud-based solutions supporting data and knowledge integration in bioinformatics
… members, adequately supported by easy access to biomedical ontologies, define and enrich network nodes with annotations derived from available ontologies. The study presents a cloud-based application called Collaborative Workspaces in Biomedicine (COWB) which deals with supporting users in the …
