Is there any Treebank for free? [closed]
Domanda
Is any place I can download Treebank of English phrases for free or less than $100? I need training data containing bunch of syntactic parsed sentences (>1000) in English in any format. Basically all I need is just words in this sentences being recognized by part of speech.
Soluzione
NLTK (for Python) offers several treebanks for free.
