Description copied from interface: Tagger

Returns a list of AnalyzedTokens that assigns each term in the sentence some kind of part-of-speech information (not necessarily just one tag).

Specified by:

tag in interface Tagger

Overrides:

tag in class BaseTagger

Parameters:

sentenceTokens - the text as returned by a WordTokenizer

Throws:

IOException
