Comparing and Combining Different Expert Relations of How Land Cover Ontologies Relate

Abstract

Expressions of expert opinion are being used to relate ontologically diverse data and to identify logical inconsistency them. Relations constructed under different scenarios, from different experts and evidence combined in different ways identify different subsets of inconsistency, the reliability of which can be parameterised by field validation. It is difficult to identify one combination as being objectively “better” than other. The selection of specific experts and scenarios depends on user perspectives.
