I've got a my own POS Tagger list for Italian language. The structure of the file is very simple: one column for the word and one column for the tag. e.g.
WORD TAG
Alfredo,NNP
è,VP
un,DT
utente,NN
Knime,NN (NN by default)
I wish I know whether it is possible to use it in Knime (like the Stanford Tagger Node)
the Dictionary tagger can assign only one tag value per dictionary. This means you can not set differnt tag values e.g. nouns and verbs using one dictionary / tagger node. You need to create a dictonary for each tag value e.g. one for nouns one for verbs. The tag vaklue to assign can be set in the dialog of the node.
