Another problem affecting Chinese NLP is that text doesn't come pre-segmented with spaces between words and segmentation errors can produce total nonsense.
E.g. 我们很快会谈到这个的。[0] "We'll talk about this soon." Should be segmented like 我们(we)很(very)快(quick)会(will)谈(talk)到(get to)这个(this)的(emphasis)。Literally, "We will very quickly get to talk about this!" But 会谈 is also a noun meaning "negotiation", so the sentence could end up as "We are very quick negotiation gets to this!" which is still kind of comprehensible, but loses the future aspect, so it might as well be a comment about how quickly the negotiation has progressed.
This kind of error affects all downstream tasks. Try doing named-entity recognition when names keep getting partially glued to surrounding words. Very annoying.
