How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Background The increasing adoption of ontologies in biomedical research and the growing number of ontologies available have made it necessary to assure the quality of these resources. Most of the well-established ontologies, such as the Gene Ontology or SNOMED CT, have their own quality assurance processes. These have demonstrated their usefulness...

Quantitative metrics are generally applied by scientists to measure and assess the properties of data and knowledge resources. In ontology engineering, a number of metrics have been developed to analyse different features of ontologies in the last few years. However, this community has not generated any standard framework for studying the propertie...
Article
The development and application of biological ontologies have increased significantly in recent years. These ontologies can be retrieved from different repositories, which do not provide much information about quality aspects of the ontologies. In the past years, some ontology structural metrics have been proposed, but their validity as measurement...
Conference Paper
The interoperability of Electronic Health Records (EHR) and Clinical Decision Support (CDS) systems is a major challenge in the medical informatics field. International initiatives propose the use of ontologies for bridging both types of systems. The next-generation of EHR and CDS systems are supposed to use ontologies, or at least ontologies shoul...
Article
The biomedical community has now developed a significant number of ontologies. The curation of biomedical ontologies is a complex task as they evolve rapidly, being new versions regularly published. Therefore, methods to support ontology developers in analysing and tracking the evolution of their ontologies are needed. OQuaRE is an ontology evaluat...

Background The biomedical community has now developed a significant number of ontologies. The curation of biomedical ontologies is a complex task and biomedical ontologies evolve rapidly, so new versions are regularly and frequently published in ontology repositories. This has the implication of there being a high number of ontology versions over a...
Article

Objective: To (1) evaluate the GoodOD guideline for ontology development by applying the OQuaRE evaluation method and metrics to the ontology artefacts that were produced by students in a randomized controlled trial, and (2) informally compare the OQuaRE evaluation method with gold standard and competency questions based evaluation methods, respec...
Article
Full-text available
The increasing importance of ontologies has resulted in the development of a large number of ontologies in both coordinated and non-coordinated efforts. The number and complexity of such ontologies make hard to ontology and tool developers to select which ontologies to use and reuse. So far, there are no mechanism for making such decisions in an in...

The development of the Semantic Web has provoked an increasing interest in the development of ontologies. There are, however, few mechanisms for guiding users in making informed decisions on which ontology to use under given circumstances. In this paper, we propose a framework for evaluating the quality of ontologies based on the SQuaRE standard fo...

Existen modelos para estimación del esfuerzo requerido en proyectos software que presentan limitaciones cuando se utilizan en etapas tempranas del ciclo de vida de desarrollo. En este artículo se presenta una revisión de los modelos existentes y se describe un nuevo modelo capaz de estimar esfuerzo en las primeras etapas del desarrollo, cuyas entra...
Article
Existen modelos para estimación temprana del esfuerzo requerido en el desarrollo de proyectos software que retornan valores muy precisos si se utilizan en fases avanzadas del desarrollo, pero que presentanlimitaciones si se usan en las fases iniciales. En este artículo se presenta un modelo que permite estimar durante las primeras fases del desarro...
