Problems with Browsing Semantics Digital Enterprise Research Institute www.deri.ie 4

Problems with Browsing Semantics Digital Enterprise Research Institute www.deri.ie  Interconnected metadata  Keyword search is not enough.  Still not everyone knows how to use it. 4

Problems with Browsing Semantics Digital Enterprise Research Institute www.deri.ie  Interconnected metadata  Keyword search is not enough.  Still not everyone knows how to use it.  Unstructured metadata  Faceted navigation is hard to construct.  Concept of the graph is still hard to understand by most people. 4

Problems with Browsing Semantics Digital Enterprise Research Institute www.deri.ie  Interconnected metadata  Keyword search is not enough.  Still not everyone knows how to use it.  Unstructured metadata  Faceted navigation is hard to construct.  Concept of the graph is still hard to understand by most people.  Why the Semantic Web is the Web 3.0 ?  Semantics are hard.  Tags are easy. 4
