It really depends on what you count as syntactic and semantic information. As a linguist, to me syntactic information is tree structures, syntactic categories, etc., and semantics is formulas in some (typically higher-order) logic. But for a lot of the NLP that I see, "syntax" is pretty shallow stuff like head words and POS tag contexts, and "semantics" is at best things like word vectors maybe dependency trees. These are very different. But maybe we're thinking of different things! :)
