    “It should be noted that there is not always a perfect match between the logically possible systems displayed above and the PoS systems actually encountered in the sample languages. As the data in the next sub-section will show, languages may display an additional PoS class from a ‘neighboring’ system (i.e. the one represented above or below it), or they may display additional closed or derived classes of rigid lexemes.”

    “Consequently, a good PoS tagger should be able to reach a degree of precision which goes beyond the superficial level of Noun/Verb/Adjective/Adverb/Grammar words.”

    “In a second step, each word is automatically attributed a certain part-of-speech category, such as noun, verb and alike, which is best illustrated by an example given in Fig. 4.1. […] A LCCRF can be used to predict a certain label sequence (the PoS tags) y* = {y₁, y₂,…,y_L} given a certain input word sequence w = {w₁, w₂,…,w_L} that maximizes the conditional probability p(y|w).”

    “The PoS tag of the word ‘live’ leads to drastic differences in its pronunciation (/liv/ when used as a verb and /lahyv/ when used as an adverb or adjective). The PoS tagger can be a simple rule-based system Brill (1992), a data-driven technique (Brants 2000) or a hybrid approach. There are also a few standard corpora that contain word-PoS pairs.”

    “In PoS tagging, the sentences in the data set collection are tokenized using the PoS tagger. During this process, a part of speech such as noun, verb, adverb, adjective, conjunctions, negations and the like are assigned to every word in the sentences.”
