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.

For more information on AgreementMakerLight, please check the Publications section.


AgreementMakerLight's alignment repair algorithm has been used to create the reference alignments for the Large Biomedical Ontologies track. Following a preliminary study, we are planning to use it to annotate BioPortal mappings with information about their logical conflicts.

AgreementMakerLight has been used by the Janssen Pharmaceutical Companies of Johnson & Johnson, in a project from Purdue University, and in the Global Agricultural Concept Scheme (GACS) from the Food and Agriculture Organization of the United Nations.


AgreementMakerLight was very successful in the OAEI 2014 competition, ranking first in F-measure in the following tracks: Anatomy, Conference, Multifarm, Library, Interactive Matching Evaluation, and Large Biomedical Ontologies.

The alignments produced by AgreementMakerLight are available here as well as in the OAEI results pages.
