Abstract

LogMap is a highly scalable ontology matching system with ‘built-in’
reasoning and diagnosis capabilities. To the best of our knowledge, LogMap is
the only matching system that can deal with semantically rich ontologies
containing tens (and even hundreds) of thousands of classes. In contrast to
most existing tools, LogMap also implements algorithms for ‘on the fly’
unsatisfiability detection and repair. Our experiments with the ontologies NCI,
FMA and SNOMED CT confirm that our system can efficiently match even the largest
existing bio-medical ontologies. Furthermore, LogMap is able to produce a
‘clean’ set of output mappings in many cases, in the sense that the
ontology obtained by integrating LogMap’s output mappings with the input
ontologies is consistent and does not contain unsatisfiable classes. LogMap has
also participated the 2011 edition of the Ontology Alignment Evaluaton
Initiative providing the second best results in terms of F-measure in the
Anatomy track (the largest test within the campaign) and being the fastest tool
(25 times faster than the best tool and more than 75 times faster than the third
best tool).
