•Semantic Interoperability is enabled through:
 –Establishing base
 semantic representation via ontologies (class level) and their
 knowledge bases (instance level)
 –Defining semantic
 mappings & transformations among ontologies (and treating these mappings as
 individual theories just like ontologies)
 –Defining algorithms
 that can determine semantic similarity and employing their output in a
 semantic mapping facility that uses ontologies
 •The use of ontologies
 & semantic mapping software can reduce the loss of semantics (meaning) in
 information exchange among heterogeneous applications, such as:
 –Web Services
 –E-Commerce,
 E-Business
 –Enterprise
 architectures, infrastructures, and applications
 –Complex C4ISR
 systems-of-systems 
 –Integrated
 Intelligence analysis
