A Desirable Case -- Pop Music Ontology (2) ,[object Object],[object Object],[object Object]

Key Difficulties 1 : Logic breakdown ,[object Object],Ontology [subject][predicate][object] [subject][predicate][object] [subject][predicate][object] [subject][predicate][object] ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Classes and Slots Instances Can complex ontology be broken down into group of single sentences? Or say, how to decompose complex description logic statement into very simple FOPL sentences? And inverse composition is also needed. Each single sentences is as simple as A is B , A has B

Key Difficulties 2 : Ontology Evolution ,[object Object],[object Object],[object Object],[object Object]

Key Difficulties 3 : Ontology Mining ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Comparison: In content-based retrieval of video database, automatic discovery of semantics based on image processing / pattern recognition are proven not quite successful. Semantics from expert knowledge are needed in MPEG 7 stream.
