Quantities in OWL

چکیده
It is essential to be able to incorporate representation of quantities into models of many domains. Many ontologies attempt to axiomatize a theory of quantities in OWL so that they may incorporate quantities in their ontologies. However, OWL based axiomatizations suffer from a number of problems including the impossibility of representing (and computing) conversions in OWL 1. While there are proposed extensions to OWL that would allow for linear equations (and thus, in principle, handle a large class of conversions), we argue that OWL based axiomatizations are, nevertheless, suboptimal from several perspectives. Instead, we propose a new datatype system for handling quantities and show that it is superior from both a modeling and an implementation point of view.

Ontology of units of measure and related concepts
This paper describes the Ontology of units of Measure and related concepts (OM), an OWL ontology of the domain of quantities and units of measure. OM supports making quantitative research data more explicit, so that the data can be integrated, verified and reproduced. The various options for modeling the domain are discussed. For example, physical quantities can be modeled either as classes, in...
متن کاملAberOWL: an ontology portal with OWL EL reasoning
The field of biological and biomedical science quickly generate large quantities of data and knowledge; often, domain knowledge is formalised using ontologies expressed in the Web Ontology Language (OWL). Ontology repositories such as Bioportal and Ontobee have been an important infrastructural component for managing ontologies, specifically to search, browse and download ontologies over the We...
متن کاملConversion of Physical Quantity and its Application
In this presentation, we show the design of a vocabulary set for the conversion of physical quantities and a prototype application using it. The vocabulary consists of facts and rules and is formalized with the W3C Web Ontology Language (OWL) under a resource description framework (RDF). Here, facts are physical quantities of things such as the weight of the Statue of Liberty, and rules are con...
متن کاملAn Executive Approach Based On the Production of Fuzzy Ontology Using the Semantic Web Rule Language Method (SWRL)
Today, the need to deal with ambiguous information in semantic web languages is increasing. Ontology is an important part of the W3C standards for the semantic web, used to define a conceptual standard vocabulary for the exchange of data between systems, the provision of reusable databases, and the facilitation of collaboration across multiple systems. However, classical ontology is not enough ...
متن کاملAssessment of toxicity and potential risk of the anticoagulant rodenticide diphacinone using Eastern screech-owls (Megascops asio).
In the United States, new regulatory restrictions have been placed on the use of some second-generation anticoagulant rodenticides. This action may be offset by expanded use of first-generation compounds (e.g., diphacinone; DPN). Single-day acute oral exposure of adult Eastern screech-owls (Megascops asio) to DPN evoked overt signs of intoxication, coagulopathy, histopathological lesions (e.g.,...
