Framework for Matching and Linking Large Ontologies

The Linked Open Data (LOD) initiative is the first large-scale attempt at realizing the Semantic Web vision of Tim Berners-Lee. As of September 2011, there are almost 300 knowledge bases linked together and available for public access through both web browsers as well as semantic applications. However, the task of building the links between knowledge basesis still a laborious manual task and as the LOD cloud continues to grow rapidly,the task becomes more daunting. This paper looks at the AGROVOC thesaurus developed and maintained by the United Nations Food and Agriculture Organization (UN FAO), and how a framework can be developed to semiautomatically discover links between AGROVOC and other knowledge bases on the LOD.
