有没有办法正确标记（PoS 标记）一起形成短语的单词？

Question

I tried various means to correctly tag a bunch of words which form a phrase (especially Noun Phrase) but could not succeed.

Example: 'the', 'first', 'early','morning', 'sunbeams'

'early' and 'morning' are wrongly being tagged as 'Noun' where expected outcome should be: ('first', 'adverb'), ('early', 'adverb'), ('morning', 'adjective'), ('sunbeams', 'noun')

Could you please suggest a procedure to tag these words correctly?

Thanks in advance.

Answer 1

POS taggers normally use Hidden Markov Models. If your data is not tagged correctly with these methods, then either your tagger (selfmade?) is not suited for your input data or your training data is not adequate (too small, false annotations etc.). Various means I assume to be taggers from NLTK, spaCy, or tools from Stanford ( https://nlp.stanford.edu/software/ ). These software packages will do the job in the quality of current research, so if it is still error-prone, you won't be able to fix it. If you have a large cluster at hand, build your own tagger using n-grams with n > 3, if you like, but I doubt this will be any better than the modules named above.
