Cannot proritize the parts of speech of a word on a particular mood

[rExQone]

Hi, I have seen the vocabulary sets of RiTa.js with pronunciation and categories of parts of speech against words. But any word that is shared in different categories cannot returns the specific category on the basis of context rather it returns the first category (I hope it makes sense). For example:
the word Ram is a verb as well as a proper noun but whatever the context is, it always returns only the first category.

This should not be the case, assuming you pass the entire sentence for pos-tagging. Do you have the full sentence, and/or any other examples? Thanks
