This paper proposes a model for formalizing concept characteristics in a manner consistent with the Terminology theoretical framework. We will focus on the identification of the elements that take part in characteristic formalization and their role, as well as on the double nature of characteristic. Finally, we provide a preliminary outline of characteristics description formalization using an ...

Protégé is one of the most widely used development platforms for ontology-based systems. We report on our experiences with the development of OWL support for Protégé, and on the experiences of our user community with OWL. While the overall feedback from the community has been positive, our experience suggests that there are considerable gaps between the user requirements, the expressivity of OW...

Ontologies have been widely used in advanced information systems. However, it has been a challenging issue in ontology engineering to efficiently revise ontologies as new information becomes available. A novel method of revising ontologies has been proposed recently by Wang et al. However, related algorithms have not been implemented yet. In this article we describe an implementation of these a...

We present Protégé-OWL extensions designed to help scientists define domain-specific ontologies for describing observational data. The extensions provide high-level forms that users can fill out from within Protégé to specify classes used to describe scientific measurements. As a user fills out a form, underlying OWL-DL axioms are automatically asserted, thus allowing users to specify relativel...

The mentorship best practices discussed in this document have been compiled from meetings and discussions with senior mentors, faculty and students throughout the College of Medicine, the Center for Clinical and Translational Science, and the Department of Internal Medicine. In addition, literature suggesting best practices for mentors has also been considered in the formulation of the practice...

For analysing the connection between computer vision and ontology, we put ourselves in a classification context. Given a pattern x to classify (a fish image), we consider two classes chromis margaritifer and zebrasoma flavescent. The ontology helps in a sense that it can specify the two fishes in terms (following the Protégé sintax) of classes, subclasses, object properties, individuals, data p...

In this paper we describe a plug-in (OntoLT) for the widely used Protégé ontology development tool that supports the interactive extraction and/or extension of ontologies from text. The OntoLT approach provides an environment for the integration of linguistic analysis in ontology engineering through the definition of mapping rules that map linguistic entities in annotated text collections to co...

In this talk we will explore the use of visualization as a cognitive aid for managing ontologies and knowledge representations. We discuss how we have integrated two interactive visualization tools (Jambalaya and PROMPTViz) with the Protégé system. First, we present Jambalaya, a plug-in developed to help users visualize, navigate, and ultimately understand an ontology. Secondly, we present the ...

A general-purpose text annotation tool called Knowtator is introduced. Knowtator facilitates the manual creation of annotated corpora that can be used for evaluating or training a variety of natural language processing systems. Building on the strengths of the widely used Protégé knowledge representation system, Knowtator has been developed as a Protégé plug-in that leverages Protégé’s knowledg...

We present an new Protégé plugin for constructing a minimal satisfiability model of an OWL ontology and visualizing it in the original music score notation.
