PBD solution to adding semantics. Problem : no one with a diverse base of content wants to hand-annotate every page and datum Solution : annotate a few pages/data, and use programming-by-demonstration to (semi-) automatically annotate the rest

PBD solution to adding semantics • Problem: no one with a diverse base of content wants to hand-annotate every page and datum • Solution: annotate a few pages/data, and use programming-by-demonstration to (semi-) automatically annotate the rest • Hard part: how does the PBD system represent the content and transformation? Is it enough to use XPATH and XHTML? Or something more?
