Coordinating Taxonomies: Key to Re-Usable Concept Representations
نویسنده
چکیده
A unified controlled medical vocabulary has been cited as one of the grand challenges facing Medical Informatics. We would restate this challenge as ‘achieving a re-usable and application-independent representation of medical concepts.’ Achieving a re-usable representation of medical concepts is a pre-requisite for meeting two key strategic goals of the next decade of the development in medical informatics: interoperability and cumulative development. A key strategy for achieving re-usability is to separate concepts into their component parts, organise those parts in nearly pure hierarchies, and then recombine into composite representations which can be classified flexibly and automatically. This paper explores the means and consequences of this strategy as implemented in the GALEN project. It discusses both the strengths — providing greater detail, greater computer support, and avoiding many arguments which are endemic in discussions of classification systems — and the limitations intrinsic in such a formal approach.

Experience building a Large, Re-usable Medical Ontology using a Description Logic with Transitivity and Concept Inclusions
The European GALEN project is developing terminology services based on a large, re-usable medical ontology. The ontology is being built using GRAIL, a description logic with transitivity and general concept inclusions.
متن کاملTopographies of Hate: Islamophobia in Cyberia
Islamophobia’s occurrence in any particular country has little do with the presence of Muslim; it is possible to be Islamophobic when there are virtually no Muslim around. This because the lack of Muslims is filled by the surplus of Islamophobic representations. This surplus of representations is now increasingly reliant on the internet. There are many studies reporting on Islamophobia on the i...
متن کاملConcept Lattice Representations of Annotated Taxonomies
We show how the concept of an annotated ordered set can be used to model large taxonomically structured ontologies such as the Gene Ontology. By constructing a formal context consistent with a given annotated ordered set, their concept lattice representations are derived. We develop the fundamental mathematical relations present in this formulation, in particular deriving a conceptual pre-order...
متن کاملEEH: AGGH-like public key cryptosystem over the eisenstein integers using polynomial representations
GGH class of public-key cryptosystems relies on computational problems based on the closest vector problem (CVP) in lattices for their security. The subject of lattice based cryptography is very active and there have recently been new ideas that revolutionized the field. We present EEH, a GGH-Like public key cryptosystem based on the Eisenstein integers Z [ζ3] where ζ3 is a primitive...
