The National Center for Biomedical Ontology (NCBO) is one of the National Centers for Biomedical Computing funded under the NIH Roadmap Initiative. Contributing to the national computing infrastructure, NCBO has developed BioPortal, a web portal that provides access to a library of biomedical ontologies and terminologies (http://bioportal.bioontology.org)(More)
Ontologies are becoming so large in their coverage that no single person or a small group of people can develop them effectively and ontology development becomes a community-based enterprise. In this paper, we discuss requirements for supporting collaborative ontology development and present Collaborative Protégé—a tool that supports many of these(More)
In this paper, we present Web-Protégé—a web-based lightweight ontology editor. Web-Protégé is open source, uses the Google Web Toolkit (GWT) for the user interface, and Protégé for supporting ontology services. We used components of Collaborative Protégé to augment the ontology-editing environment with facilities for discussions and annotations. In this(More)
In this paper, we present WebProtégé-a lightweight ontology editor and knowledge acquisition tool for the Web. With the wide adoption of Web 2.0 platforms and the gradual adoption of ontologies and Semantic Web technologies in the real world, we need ontology-development tools that are better suited for the novel ways of interacting, constructing and(More)
We present an extension of the existing Protégé system that supports collaborative ontology editing. The extended system—Collaborative Protégé—is currently available as a prototype. In addition to the common ontology editing operations, it enables annotation of both ontology components and ontology changes. It supports the searching and filtering of user(More)
The World Health Organization is using Semantic Web technologies in the development of the 11 revision of the International Classification of Diseases (ICD-11). Health officials use ICD in all United Nations member countries to compile basic health statistics, to monitor health-related spending, and to inform policy makers. In 2010, we published a paper in(More)
The World Health Organization is currently developing the 11th revision of the International Classification of Diseases (ICD-11). ICD is the standard diagnostic classification used in health care all over the world. In contrast to previous ICD revisions that did not have a formal representation and were mainly available as printed books, ICD-11 uses OWL for(More)
UNLABELLED WebProtégé is an open-source Web application for editing OWL 2 ontologies. It contains several features to aid collaboration, including support for the discussion of issues, change notification and revision-based change tracking. WebProtégé also features a simple user interface, which is geared towards editing the kinds of class descriptions and(More)
Ontologies are becoming so large in their coverage that no single person or a small group of people can develop them effectively and ontology development becomes a community-based enterprise. We present Collaborative Protégé—an extension of the Protégé ontology editor that we have designed specifically to support the collaboration process for a community of(More)
The World Health Organization is beginning to use Semantic Web technologies in the development of the 11th revision of the International Classification of Diseases (ICD-11). Health officials use ICD in all United Nations member countries to compile basic health statistics, to monitor health-related spending, and to inform policy makers. While previous(More)
