Help?

[venta]

Just had an email from a friend who teaches computer science at A-level, and is baffled by an exam question his students asked him about.

Can anyone offer definitions of the following:

syntactic representation of knowledge
semantic representation of knowledge
direct manipulation interface

Some quick googling offered little help on the first two, and suggested that the last one is a Can Of Worms (TM). I've found a couple of pages waffling vaguely about direct manipulation, once of which describes it as "complex, compound, important and often poorly defined construct". Which is nice.

Thanks to all for suggestions.
