Ontology Matching - Managing heterogeneous data sources semantically

Hi, this is a Semantic Web in-class presentation. As a database researcher, I will focus on the topic of managing heterogeneous data sources semantically from the perspective of ontology matching. It is also named ontology mapping, ontology alignment in semantic web community. However, I will adopt ontology matching throughout the presentation. Regarding this topic, I will answer 3 questions: (i) Why we need ontology and ontology matching? (ii) What is ontology and ontology matching? (iii) How to do ontology matching, based on the latest best research project, published at SIGMOD 2007? airchendb@gmail.com
