  Typically an ontology matching technique is a combination of much different
type of matchers operating at various abstraction levels such as structure,
semantic, syntax, instance etc. An ontology matching technique which employs
matchers at all possible abstraction levels is expected to give, in general,
best results in terms of precision, recall and F-measure due to improvement in
matching opportunities and if we discount efficiency issues which may improve
with better computing resources such as parallel processing. A gold standard
ontology matching model is derived from a model classification of ontology
matching techniques. A suitable metric is also defined based on gold standard
ontology matching model. A review of various ontology matching techniques
specified in recent research papers in the area was undertaken to categorize an
ontology matching technique as per newly proposed gold standard model and a
metric value for the whole group was computed. The results of the above study
support proposed gold standard ontology matching model.
