POS Tagging approaches

Rule$-$based taggers are also known as syntagmatic taggers. Which of the following correctly explains the role of these taggers?

Syntagmatic taggers first use statistical techniques to extract information from the training corpus and then use predefined rules to reduce mistakes committed by the statistical technique

Syntagmatic tagger use only probabilistic method to tag the sequence of words

Syntagmatic tagger use recurrent neural networks to tag the words in a sentence
