Solving Ontology Meta-Matching Problem Through an Evolutionary Algorithm With Approximate Evaluation Indicators and Adaptive Selection Pressure

open access: yesIEEE Access, 2021
Ontology applies commonly to solve the problem of heterogeneity of data in the Semantic Web, but the heterogeneity problem between two ontologies seriously affects their communication.

Ontology Alignment Repair Through 0-1 Programming

open access: yesIEEE Access, 2019
In order to solve the problem of lack of effective methods for ontology inconsistency, a user preferences-oriented ontology alignment repair model is proposed.

Reaching agreement over ontology alignments [PDF]

open access: yes, 2006
When agents communicate, they do not necessarily use the same vocabulary or ontology. For them to interact successfully, they must find correspondences (mappings) between the terms used in their respective ontologies.

A Compact Brain Storm Algorithm for Matching Ontologies

open access: yesIEEE Access, 2020
An ontology can formally present the domain knowledge by specifying the domain concepts and their relationships, which is a kernel technique for addressing the data heterogeneity issue in the semantic web. However, since existing ontologies are developed

DAEOM: A Deep Attentional Embedding Approach for Biomedical Ontology Matching

open access: yesApplied Sciences, 2020
Ontology Matching (OM) is performed to find semantic correspondences between the entity elements of different ontologies to enable semantic integration, reuse, and interoperability.

Reasoning with a Network of Aligned Ontologies [PDF]

open access: yes, 2008
In the context of the Semantic Web or semantic P2P systems, many ontologies may exist and be developed independently. Ontology alignments help integrating, mediating or simply reasoning with a system of networked ontologies. Though different formalisms have already been defined to reason with such systems, they do not consider ontology alignments as ...

Ontology Similarity in the Alignment Space [PDF]

open access: yes, 2010
Measuring similarity between ontologies can be very useful for different purposes, e.g., finding an ontology to replace another, or finding an ontology in which queries can be translated. Classical measures compute similarities or distances in an ontology space by directly comparing the content of ontologies.

Assessing Ontology Mappings on a Level of Concepts and Instances

open access: yesIEEE Access, 2020
In recent years, the number of domain ontologies on the Internet has been steadily increasing. Many ontologies describe overlapping universes of discourse in various ways, therefore, the need for an efficient ontology alignment method is required ...

An API for Ontology Alignment [PDF]

open access: yes, 2004
Ontologies are seen as the solution to data heterogeneity on the web. However, the available ontologies are themselves source of heterogeneity. This can be overcome by aligning ontologies, or finding the correspondence between their components. These alignments deserve to be treated as objects: they can be referenced on the web as such, be completed by

Using Partial Reference Alignments to Align Ontologies [PDF]

open access: yes, 2009
In different areas ontologies have been developed and many of these ontologies contain overlapping information. Often we would therefore want to be able to use multiple ontologies. To obtain good results, we need to find the relationships between terms in the different ontologies, i.e. we need to align them.
