Ontology segmentation in ontology matching

open access: yes2017 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.

Semantic

open access: yesJournal of King Saud University: Computer and Information Sciences, 2014
Hierarchical ontologies play a key role in organizing documents in a repository. While matching the ontologies, the relationships among the concepts are considered to be a major aspect.

On the succinctness of query rewriting over shallow ontologies [PDF]

open access: yes, 2014
We investigate the succinctness problem for conjunctive query rewritings over OWL2QL ontologies of depth 1 and 2 by means of hypergraph programs computing Boolean functions. Both positive and negative results are obtained.

Formal Ontologies and Uncertainty. In Geographical Knowledge

open access: yesTeMA: Journal of Land Use, Mobility and Environment, 2014
Formal ontologies have proved to be a very useful tool to manage interoperability among data, systems and knowledge. In this paper we will show how formal ontologies can evolve from a crisp, deterministic framework (ontologies of hard knowledge) to new ...

EPPO ontology: a semantic-driven approach for plant and pest codes representation

open access: yesFrontiers in Artificial Intelligence, 2023
The agricultural industry and regulatory organizations define strategies and build tools and products for plant protection against pests. To identify different plants and their related pests and avoid inconsistencies between such organizations, an agreed

Ontology, Ontologies, and Science [PDF]

open access: yesTopoi, 2011
Philosophers frequently struggle with the relation of metaphysics to the everyday world, with its practical value, and with its relation to empirical science. This paper distinguishes several different models of the relation between philosophical ontology and applied (scientific) ontology that have been advanced in the history of philosophy.

Ontological positions

open access: yes, 2023
The aim of this foundational chapter is to explore some of the main ways that ontology – that is, the study of being – is relevant to translation. It begins by considering the importance of the broad questions of being and the peculiar difficulty of reflecting on them directly.

Representation Phase: Ontology Usage Ontology (U Ontology)

open access: yes, 2018
The huge increase in the use of ontologies and Semantic Web data has increased the need for usage-related information to assist stakeholders (or users) to make effective use of currently available semantic information. As noted in earlier chapters, stakeholders can be different groups of users such as ontology developers, domain experts, application ...

Function‐driven design of a surrogate interleukin‐2 receptor ligand

open access: yesFEBS Letters, EarlyView.
Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in

Inhibiting stearoyl‐CoA desaturase suppresses bone metastatic prostate cancer by modulating cellular stress, mTOR signaling, and DNA damage response

open access: yesFEBS Letters, EarlyView.
Bone metastasis in prostate cancer (PCa) patients is a clinical hurdle due to the poor understanding of the supportive bone microenvironment. Here, we identify stearoyl‐CoA desaturase (SCD) as a tumor‐promoting enzyme and potential therapeutic target in bone metastatic PCa.
