Sensor Ontology Metamatching with Heterogeneity Measures

Table 1

The brief descriptions on OAEI’s testing cases and real sensor ontologies.

Ontology		Brief description
OAEI	101-104	The ontology pairs to be matched in the cases are identical or have different constraints in OWL.
	201-210	The concept language features of the ontology pairs to be matched are different, but the structure of them is the same.
	221-247	The concept structure of the ontology pairs to be matched is different, but the language features of them are the same.
	248-262	The ontology pairs to be matched in the cases have different lexical, linguistic, and structure features.
Real sensor ontologies	Original SSN	Description of sensors and observations and related concepts.
	New SSN	Addressing changes in scope and audience, shortcomings of the original SSN, and new technical developments.
	SOSA	As a lightweight core for SSN.
