-In most cases, a tagger assigns tags representing morpho-syntactic information to single word-forms or token. But there are tagger which have been designed to identify semantic role of noun phrases or prepositional phrases ([[sense tagging]]) and sometimes identifying the structure of a text is considered as a king of tagging ([[discourse structure tagging]]).

 Conceptually, tagging can be considered as a three step process: (i). identification of the relevant units (ii). assigning all possible labels (e.g. by lexical look-up, applying heuristics, etc.) (iii). disambiguation.
-It is common practice to distinguish between rule-based and stochastic tagger, though some tagger combine rules and stochastic information.

-In general, state-of-the-art tagger achieve a precision of at least 95% for morpho-syntactic tagging.
