Locally Constrained Ontologies

Karlis Podnieks
2016 Baltic Journal of Modern Computing  
In the paper, properties of locally constrained ontologies ("locality phenomena") are explored, and Generalized Granularity Theorem is proved, showing that in the Granularity Theorem, all restrictions  ...  It appears that the principal cause of the "tree phenomenon" is the local character of ontology constraints expressed by graphical means of UML class diagrams (roughly, each of such constraints involves  ...  (First Locality Phenomenon) Assume O is a locally constrained ontology.  ...

Local Safety of an Ontology

Lukás Homola, Julius Stuller
2009 Conference on Theory and Practice of Information Technologies  
In this paper, we propose the notion of local safety of an ontology and we identify scenarios in which this notion may be useful in guiding the development of an ontology that is to import other ontologies  ...  The ability to import ontologies safely, that is, without changing the original meaning of their terms, has been identified as crucial for the collaborative development and the reuse of (OWL) ontologies  ...  In [23] , a syntactic characterization of localness for SHOIQ ontologies is given, which allows one to check localness of an SHOIQ ontology in polynomial time.  ...

Local Change in Ontologies with Atomic Decomposition

Ricardo Guimarães, Renata Wassermann
2017 Joint Ontology Workshops  
point of the theory of Local Change.  ...  Thus, in this work, we aim to devise a relevance metric using atomic decomposition, originated in the field of Ontology Modularisation, and embed it into the framework of Local Change.  ...  Moreover, we formulate a relevance metric over axioms using the atomic decomposition and derive from it localized operators of change for description logic ontologies.  ...

A Query Driven Method of Mapping from Global Ontology to Local Ontology in Ontology-based Data Integration

Haifei Zhang
2014 Journal of Software  
The key of this method is building of mapping from the global ontology in mediator to the local ontology in wrapper.  ...  decomposition and makes the ontology-based integration system has very good extensibility.  ...  GAV Mapping In GAV, term G T in the global ontology is regarded as a view of the local ontology, such as query L Q of the local ontology.  ...

An Ontology of Nature with Local Causality, Parallel Lives, and Many Relative Worlds [article]

Mordecai Waegell
2017 arXiv   pre-print
Parallel Lives (PL) is an ontological model of nature in which quantum mechanics and special relativity are unified in a single universe with a single space-time.  ...  Each life carries an internal memory containing a local relative wavefunction, which is a local piece of a pure universal wavefunction, but only the relative wavefunctions are physically real in PL, and  ...  The fact that PL is an ontology of fundamental point-like objects in space-time -which obey all of the constraints of special relativity and local causality, instead of a theory of a fundamental universal  ...

Ontology from Local Hierarchical Structure in Text [article]

F. Murtagh, J. Mothe, K. Englmeier
2007 arXiv   pre-print
While detailing a generic framework, a distinguishing feature of our work is that we focus on locality of hierarchic structure in order to extract semantic information.  ...  Ontologies are likely to be of immediate help in supporting querying. For example, the query model may be based on the ontology (or ontologies) used.  ...  We have locality of the relationship in any given triplet, from successive terms. The relationship is strictly local to the given triplet.  ...

Local ontology for a dual-rail qubit

Pawel Blasiak
2016 Journal of Physics, Conference Series  
In the presented model 'non-locality' appears only on the epistemic level of description.  ...  We show that quantum predictions for the dual-rail realisation of a qubit can be faithfully simulated with classical stochastic gates and particles which interact entirely in a local manner.  ...  We emphasise that the model is local on the ontological level, and alleged 'non-locality' is only an epistemic effect caused by restrictions on gaining knowledge.  ...

The locality of quantum subsystems II: A 'local sum-over-paths' ontology for quantum subsystems [article]

Adam Brownstein
2017 arXiv   pre-print
Subsystems of entangled quantum systems are not traditionally described in a local way.  ...  This paper begins to address the issue by constructing an explicit local hidden variable theory for quantum subsystems.  ...  There are several reasons why the local ontology is preferable.  ...

A Separable, Dynamically Local Ontological Model of Quantum Mechanics

Jacques Pienaar
2015 Foundations of physics  
However, since dynamical locality is strictly weaker than local causality, this leaves open the question of whether an ontological model for quantum mechanics can be both separable and dynamically local  ...  We find that the resulting model violates local causality, but satisfies both separability and dynamical locality, making it a candidate for the 'most local' ontological model of quantum mechanics.  ...  It turns out that (given the basic assumptions of the framework of ontological models) dynamical locality and factorisation alone are sufficient for local causality.  ...

A New Expert Questioning Approach to More Efficient Fault Localization in Ontologies [article]

Patrick Rodler, Michael Eichholzer
2022 arXiv   pre-print
Addressing this issue, several techniques for semi-automatic fault localization in ontologies have been proposed.  ...  When ontologies reach a certain size and complexity, faults such as inconsistencies, unsatisfiable classes or wrong entailments are hardly avoidable.  ...  Query-Based Fault Localization in Ontologies We briefly recap basics of query-based ontology fault localization, based on [19, 34] . As a running example we reuse the example presented in [26] .  ...

Interactive ontology debugging: Two query strategies for efficient fault localization

Kostyantyn Shchekotykhin, Gerhard Friedrich, Philipp Fleiss, Patrick Rodler
2012 Journal of Web Semantics  
However in many cases users have different local views of the domain, i.e. of the context in which a given term is used.  ...  In most debugging scenarios these methods return many alternative diagnoses, thus placing the burden of fault localization on the user.  ...  ontology is ineffective.  ...
