Querying clinical data in HL7 RIM based relational model with morph-RDB

Journal of Biomedical Semantics, 2017
Background Semantic interoperability is essential when carrying out post-genomic clinical trials where several institutions collaborate, since researchers and developers need to have an integrated view and access to heterogeneous data sources.

Preserving conceptual model semantics in the forward engineering of relational schemas

Frontiers in Computer Science, 2022
Forward engineering relational schemas based on conceptual models (in languages such as UML and ER) is an established practice, with several automated transformation approaches discussed in the literature and implemented in production tools.

Ontology segmentation in ontology matching

2017 International Conference on Computer Science and Engineering (UBMK), 2017
Ontologies are domain-specific constructs developed for many different purposes. But, they can be different even within the same domain. Ontology matching is a method for finding the same things in between existing ontologies by looking at semantic similarities.

Contextualizing ontologies [PDF]

Journal of Web Semantics, 2004
Ontologies are shared models of a domain that encode a view which is common to a set of different parties. Contexts are local models that encode a party's subjective view of a domain. In this paper, we show how ontologies can be contextualized, thus acquiring certain useful properties that a pure shared approach cannot provide.

Ontology Knowledge Mining for Ontology Alignment [PDF]

International Journal of Computational Intelligence Systems, 2016
Comme l'alignement des ontologies facilite l'échange de connaissances entre les sources de données hétérogènes, plusieurs méthodes ont été introduites dans la littérature. Cependant, peu d'entre elles se sont intéressées à la diminution de la complexité du problème et à la réduction de l'espace de recherche des correspondances entre les ontologies d ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Ontologies and ontological methods in linguistics [PDF]

Language and Linguistics Compass, 2019
Abstract In the last decade, linguists have started to develop and make use of ontologies, encouraged by the progress made in areas such as Artificial Intelligence and the Semantic Web. This paper gives an overview of notions and dimensions of “ontology” and of ontologies for and in linguistics.

An epithelial GPR35 isoform supports tumor‐associated transcriptional and metabolic phenotypes

FEBS Letters, EarlyView.
GPR35 generates two functionally distinct isoforms with previously unresolved roles. GPR35‐short mediates immune‐cell chemotaxis, while GPR35‐long is enriched in colorectal cancer epithelium, where it supports increased metabolism, proliferation, and tumor‐associated transcriptional programs.

Entanglement—A Higher Order Symmetry

Physical Sciences Forum, 2023
Can we accurately model the spin state of a quantum particle? If so, we should be able to make identical copies of such a state and also obtain its mirror image.
