Automatic Type Extaction
I need to extract various tags based on which we can partition an object,for eg., we can partition "car" object based on "company", "cost", "year of mfg", "Location of manufacturing unit"..etc. But i need to do it automatically (by means of some website or directory). I can use online directory like dmoz and yahoo , but they don't have many parttition types available( eg. a car would be partitioned only by company type....and not cost, location etc).
So, is there any website or directory by which i can find different ways to classify any object. Any help would be greatly appreciated.
