Abstract

Abstract Ecolingua is an ontology for ecological quantitative data, which has been designed through reuse of a conceptualisation of quantities and their physical dimensions provided by theEngMath family of ontologies. A hierarchy of ecological quantity classes is presented together with their definition axioms in first-order logic. An implementation-level application of the ontology is discussed, by way of which conceptual ecological models are synthesised from data annotations inEcolingua through reuse of existing model structures.

Highlights

  • Ecolingua is an evolving, domain-specific ontology which brings a contribution towards a conceptualisation of the Ecology domain by formalising properties of quantitative data that typically feed ecological simulation models

  • The definitions draw on the EngMath ontology to characterise quantity classes with respect to their physical dimension, which can be captured through the unit of measure in which instances of the quantity classes are expressed in

  • The ontology has been employed to enable a technique of synthesis of conceptual ecological models from metadata and reuse of existing models

Summary

Introduction

Domain-specific ontology which brings a contribution towards a conceptualisation of the Ecology domain by formalising properties of quantitative data that typically feed ecological simulation models. Ecolinguais conceptualised within the frame-system view of the world, which is wide-spread in the ontologies field, and is formalised in first-order logic (FOL). It has been developed as part of a research project on model synthesis based on metadata and ontology-enabled reuse of model designs [4].
