Interlinked instances with disjoint schemas00:33

Problem: Disconnected Ontologies00:57

Solution: Generate Alignments using Linked Data – Extensional Approach01:10

Aligning Restriction Classes Using Extensional Approach01:43

But there is a pattern to be explored in the subset relations02:16

1) Schools in GeoNames are Educational Institutions in DBpedia02:20

2) Colleges in GeoNames are Educational Institutions in DBpedia02:28

3) Universities in GeoNames are Educational Institutions in DBpedia02:33

Taken by themselves, the subset relations are not useful02:38

Using featureCode property as a hint, we form a Union of concepts02:42
