Word segmentation is particularly critical for Chinese, Japanese, and Thai NLP because these languages lack explicit space-delimited word boundaries, unlike English where space-delimited tokenization serves as a first approximation.
Summary
Systems working with Chinese, Japanese, or Thai face an extra foundational hurdle that English tools mostly skip: they must first figure out where individual words begin and end, since these languages don't use spaces to separate them. That means word segmentation is not a trivial first step but a genuinely harder problem that sits at the base of the entire processing pipeline for those languages.
