__init__(root, fileids='.*')

Corpus reader designed to work with National Corpus of Polish. See http://nkjp.pl/ for more details about NKJP. use example: import nltk import nkjp from nkjp import NKJPCorpusReader x = NKJPCorpusReader(root=’/home/USER/nltk_data/corpora/nkjp/’, fileids=’’) # obtain the whole corpus x.header() x.raw() x.words() x.tagged_words(tags=[‘subst’, ‘comp’]) #Link to find more tags: nkjp.pl/poliqarp/help/ense2.html x.sents() x = NKJPCorpusReader(root=’/home/USER/nltk_data/corpora/nkjp/’, fileids=’Wilk*’) # obtain particular file(s) x.header(fileids=[‘WilkDom’, ‘/home/USER/nltk_data/corpora/nkjp/WilkWilczy’]) x.tagged_words(fileids=[‘WilkDom’, ‘/home/USER/nltk_data/corpora/nkjp/WilkWilczy’], tags=[‘subst’, ‘comp’])

get_paths()

fileids()

Returns a list of file identifiers for the fileids that make up this corpus.

add_root(fileid)

Add root if necessary to specified fileid.

header(fileids=None, **kwargs)

Returns header(s) of specified fileids.

sents(fileids=None, **kwargs)

Returns sentences in specified fileids.

words(fileids=None, **kwargs)

Returns words in specified fileids.

tagged_words(fileids=None, **kwargs)

Call with specified tags as a list, e.g. tags=[‘subst’, ‘comp’]. Returns tagged words in specified fileids.

raw(fileids=None, **kwargs)

Returns words in specified fileids.

abspath(fileid)

Return the absolute path for the given file.

Parameters

fileid (str) – The file identifier for the file whose path should be returned.

Return type

PathPointer

abspaths(fileids=None, include_encoding=False, include_fileid=False)

Return a list of the absolute paths for all fileids in this corpus; or for the given list of fileids, if specified.

Parameters

• fileids (None or str or list) – Specifies the set of fileids for which paths should be returned. Can be None, for all fileids; a list of file identifiers, for a specified set of fileids; or a single file identifier, for a single file. Note that the return value is always a list of paths, even if fileids is a single file identifier.

• include_encoding – If true, then return a list of (path_pointer, encoding) tuples.

Return type

list(PathPointer)

citation()

Return the contents of the corpus citation.bib file, if it exists.

encoding(file)

Return the unicode encoding for the given corpus file, if known. If the encoding is unknown, or if the given file should be processed using byte strings (str), then return None.

ensure_loaded()

Load this corpus (if it has not already been loaded). This is used by LazyCorpusLoader as a simple method that can be used to make sure a corpus is loaded – e.g., in case a user wants to do help(some_corpus).

license()

Return the contents of the corpus LICENSE file, if it exists.

open(file)

Return an open stream that can be used to read the given file. If the file’s encoding is not None, then the stream will automatically decode the file’s contents into unicode.

Parameters

file – The file identifier of the file to read.

readme()

Return the contents of the corpus README file, if it exists.

property root

The directory where this corpus is stored.

Type

PathPointer
