%0 Journal Article %T State-of-the-Art: Ontology Matching Techniques and Ontology Mapping Systems %A Mohammad Mustafa Taye %J International Journal of ACM Jordan %D 2010 %I ACM Jordan ISWSA Professional Chapter %X The objective of a system of information integration is to provide a uniform view of sets ofinformation sources on the same scope, but created independently of each other, which can bedifferentiated by formats, structures, modes of access or the terms represented. More specific,ontology alignment plays an important role in solving interoperability in heterogeneous systems andin many application domains. The aim of this paper is to describe the mismatching that could appearwhen trying to integrate, map, align or match two ontologies. It also describes many matchingstrategies and operations. Finally, a comprehensive review of existing ontology alignment tools.Several existing ontology mapping methods were analysed and compared, since before creating a newapproach it is essential to fully understand related work. Here, this means both theoretical work andexisting approaches to the alignment of ontologies or other well-defined structures, including theirweaknesses, which must be understood if they are to be improved. %K Ontology %K Semantic Web %K Ontology Matching %K Ontology Alignment %U http://iswsa2010.acm.org/volumes/volume1/no3/ijjvol1no3p8.pdf
