AgreementMakerLight is an automated and efficient ontology matching system derived from AgreementMaker that has been in development since the beginning of 2013. It is open source and freely available through GitHub both as an Eclipse project and as an executable jar.

Like its namesake, AgreementMakerLight has a flexible and extensible framework, but places more emphasis on efficiency so as to tackle large ontology matching problems. It is primarily based on the use of element-level matching techniques supported by background knowledge.
