Why does a corpus linguistics project using only automatic POS tagging often yield inaccurate syntactic analysis when applied to code-switched text?

💡 Explanation

A corpus relying only on automatic POS tagging will be inaccurate for code-switched text because the inherent grammatical structures within each sentence are not properly disambiguated, therefore contextual information is lost. Accurate analysis demands manually annotated information, rather than relying solely on automated taggers which don't handle code-switching well.
