Identifying Ontological Mismatches Between EcoLexicon and FunGramKB

Abstract

EcoLexicon is a frame-based terminological knowledge base on the in the process environment that is of being linked to FunGramKB, a multipurpose knowledge base designed for NLP. The approach chosen for the linking is the one known as alignment, which entails that EcoLexicon will become a satellite ontology of the FunGramKB core ontology, though each resource will continue to be independent. Most of the difficulties in any alignment stem from heterogeneity. The most important types of heterogeneity are syntactic, terminological, conceptual, and pragmatic. In order to define the best strategy for such an alignment and guarantee efficient maintenance afterwards, the dissimilarities between the ontologies need to be carefully studied. For that reason, this paper analyzes the ontological heterogeneities between EcoLexicon and the FunGramKB core ontology in order to identify possible ontological mismatches.
