g. lexical personality is usually lost when all individual pronouns is marked . On top of that, the marking process present brand new differences and eliminates ambiguities: e.g. price marked as VB or NN . This trait of collapsing certain distinctions and presenting latest distinctions is an important function of tagging which encourages classification and forecast. Whenever we present finer distinctions in a tagset, an n-gram tagger will get more descriptive details about the left-context if it is deciding exactly what tag to assign to a specific term. But the tagger at the same time has got to perform most work to identify the current token, due to the fact there are many more labels available. However, with less distinctions (as with the simplified tagset), the tagger keeps less information regarding context, and has now an inferior array of choices in classifying the existing token.

There are that ambiguity from inside the training facts leads to an upper limitation in tagger abilities. Occasionally even more perspective will deal with the ambiguity. In other situation but as observed by (Church, Young, Bloothooft, 1996), the ambiguity can simply end up being settled with reference to syntax, or perhaps to world understanding. Despite these imperfections, part-of-speech marking enjoys played a central part when you look at the increase of statistical approaches to organic language processing.
