Representing SNOMED CT Concept Evolutions using Process Profiles

by Werner Ceusters , Jonathan P Bona
"... Abstract. SNOMED CT is a very large biomedical terminology supported by a concept-based ontology. In recent years it has been distributed under the new release format 'RF2'. RF2 provides a more consistent and coherent mechanism for keeping track of changes over versions, even to the exten ..."

Representation of disorders of the newborn infant by SNOMED CT

by Andrew G. James, Mbchb Mbi, Fracp Frcpca, Kent A. Spackman, Md Phdb - In Proc. 21st Int. Congress of the European Federation for Medical Informatics (MIE’08 , 2008
"... Abstract. SNOMED CT ® is the most sophisticated reference terminology currently available for the representation of healthcare. An unforeseen consequence of the opportunistic evolutionary process for SNOMED CT may be that some terms for disorders of specialised clinical domains are not represented w ..."

Mining Relation Reversals in the Evolution of SNOMED CT Using MapReduce

by Shiqiang Tao, Licong Cui, Wei Zhu, Mengmeng Sun, Olivier Bodenreider Md
"... Abstract. Relation reversals in ontological systems refer to such patterns as a path from concept A to concept B in one version becoming a path with the position of A and B switched in another version. We present a scalable approach, using cloud computing, to systematically extract all hierarchical ..."

relation reversals among 8 SNOMED CT versions from 2009 to 2014. Taking advantage of our MapReduce algorithms for computing transitive closure and large-scale set operations, 48 reversals were found through 28 pairwise comparison of the 8 versions in 18 minutes using a 30-node local cloud, to completely

Building Ontologies Collaboratively Using ContentCVS

by E. Jiménez-ruiz, B. Cuenca Grau, I. Horrocks, R. Berlanga
"... OWL Ontologies are already being used in many application domains. In particular, OWL is extensively used in the clinical sciences; prominent examples of OWL ontologies are the National Cancer Institute (NCI) Thesaurus, SNOMED CT, the Gene Ontology (GO), the Foundational Model of Anatomy (FMA), and ..."

Identifying most relevant concepts to describe clinical trial eligibility criteria

by Krystyna Milian, Anca Bucur, Frank Van Harmelen, Annette Ten Teije
"... Abstract: Since eligibility criteria of clinical trials are represented as free text, their automatic interpretation and the eval-uation of patient eligibility is challenging. Our approach to the criteria processing is based on the identification of contextual patterns and semantic concepts that tog ..."
Abstract - Add to MetaCart
obtained using different concept recognizers and ontologies from UMLS Thesaurus, we chose to use MetaMap and SNOMED CT to create the mapping set. To prioritize the identified concepts, we used the tf-idf measure and the corpus of over 38, 000 various clinical trials, to detect concepts specific for breast

Abstract This article presents an innovative proposal towards a process engineering, driven by process capability profile, for software and any other knowledge intensive human work as an evolution of the current software process improvement. The proposed process engineering is based on a critical v ..."

EMF Profiles: A Lightweight Extension Approach for EMF Models

by unknown authors
"... Abstract Domain-Specific Modeling Languages (DSMLs) are getting more and more attention as a key element of Model Driven Engineering. As any other software artifact, DSMLs should continuously evolve to adapt to the changing needs of the domain they represent. Unfortunately, right now evolution of DS ..."
Abstract - Add to MetaCart
of DSMLs is a costly process that requires changing the DSML metamodel and re-creating the complete modeling environment. In this paper we advocate for the use of EMF Profiles, an adaptation of the UML Profile concept to DSMLs. Profiles have been a key enabler for the success of UML by providing a

Interaction of expanding abdominal aortic aneurysm with surrounding tissue: Retrospective CT image studies

by Sebastian T Kwon , William Burek , Alexander C Dupay , Mehdi Farsad , Seungik Baek , Eun-Ah Park , Whal Lee , Ph.D S Baek
"... Objectives: Abdominal aortic aneurysms (AAA) that rupture have a high mortality rate. Rupture occurs when local mechanical stress exceeds the local mechanical strength of an AAA, so stress profiles such as those from finite element analysis (FEA) are useful. The role and effect of surrounding tissu ..."
