Treebank construction
The nltk.corpus.package consists of a number of corpus readerclasses that can be used to obtain the contents of various corpora.
Treebank corpus can also be accessed from nltk.corpus. Identifiers for files can be obtained using fileids():
>>> import nltk >>> import nltk.corpus >>> print(str(nltk.corpus.treebank).replace('\\\\','/')) <BracketParseCorpusReader in 'C:/nltk_data/corpora/treebank/combined'> >>> nltk.corpus.treebank.fileids() ['wsj_0001.mrg', 'wsj_0002.mrg', 'wsj_0003.mrg', 'wsj_0004.mrg', 'wsj_0005.mrg', 'wsj_0006.mrg', 'wsj_0007.mrg', 'wsj_0008.mrg', 'wsj_0009.mrg', 'wsj_0010.mrg', 'wsj_0011.mrg', 'wsj_0012.mrg', 'wsj_0013.mrg', 'wsj_0014.mrg', 'wsj_0015.mrg', 'wsj_0016.mrg', 'wsj_0017.mrg', 'wsj_0018.mrg', 'wsj_0019.mrg', ...Become an O’Reilly member and get unlimited access to this title plus top books and audiobooks from O’Reilly and nearly 200 top publishers, thousands of courses curated by job role, 150+ live events each month,
