Ontological and Practical Issues in Using a Description Logic to Represent Medical Concept Systems: Experience from GALEN
Alan L. Rector,Jeremy Rogers +1 more
TLDR
The principles on which the CRM is based are discussed followed by a more detailed look at the actual mechanisms employed and the structure is compared with other biomedical ontologies in use or proposed.Abstract:
GALEN seeks to provide re-usable terminology resources for clinical systems. The heart of GALEN is the Common Reference Model (CRM) formulated in a specialised description logic. The CRM is based on a set of principles that have evolved over the period of the project and illustrate key issues to be addressed by any large medical ontology. The principles on which the CRM is based are discussed followed by a more detailed look at the actual mechanisms employed. Finally the structure is compared with other biomedical ontologies in use or proposed.read more

Hypertableau reasoning for description logics
TL;DR: This work presents a novel reasoning calculus for the description logic SHOIQ+--a knowledge representation formalism with applications in areas such as the SemanticWeb and shows significant performance improvements over state-of-the-art reasoners on several well-known ontologies.

An Ontology-Based System for Context-Aware and Configurable Services to Support Home-Based Continuous Care
Federica Paganelli,Dino Giuli +1 more
TL;DR: An ontology-based context model and a related context management system providing a configurable and extensible service-oriented framework to ease the development of applications for monitoring and handling patient chronic conditions is described.

Using ontologies for structuring organizational knowledge in Home Care assistance
TL;DR: The paper shows that the ontological paradigm and the expressiveness of modern ontology languages can be exploited not only to represent terminology in a non-ambiguous way, but also to formalize the interrelations and organizational structures involved in a real and distributed healthcare environment.
Journal ArticleDOI
A novel approach to ontology classification
TL;DR: It is shown that property classification can be reduced to class classification, which allows us to classify properties using the authors' optimised algorithm, and the results of the performance evaluation show significant performance improvements on several well-known ontologies.

TL;DR: The goal of the Gene Ontology Consortium is to produce a dynamic, controlled vocabulary that can be applied to all eukaryotes even as knowledge of gene and protein roles in cells is accumulating and changing.

Toward principles for the design of ontologies used for knowledge sharing
TL;DR: The role of ontology in supporting knowledge sharing activities is described, and a set of criteria to guide the development of ontologies for these purposes are presented, and it is shown how these criteria are applied in case studies from the design ofOntologies for engineering mathematics and bibliographic data.

Ontologies: principles, methods and applications
TL;DR: This paper outlines a methodology for developing and evaluating ontologies, first discussing informal techniques, concerning such issues as scoping, handling ambiguity, reaching agreement and producing definitions, and considers, a more formal approach.

Building Large Knowledge-Based Systems: Representation and Inference in the Cyc Project
TL;DR: This review has been difficult for me to write, because my thoughts about Cyc have changed a great deal since I first read the book in the spring of 1990 and I agree with his complaints about the confusing organization of the book and the lack of precise definitions.

Sweetening Ontologies with DOLCE
TL;DR: This paper introduces the DOLCE upper level ontology, the first module of a Foundational Ontologies Library being developed within the WonderWeb project, and suggests that such analysis could hopefully lead to an ?
