class documentation

class UdhrCorpusReader(PlaintextCorpusReader): (source)

Constructor: UdhrCorpusReader(root)

Undocumented

Method	`__init__`	Construct a new plaintext corpus reader for a set of documents located at the given root directory. Example usage:
Constant	`ENCODINGS`	Undocumented
Constant	`SKIP`	Undocumented

Inherited from PlaintextCorpusReader:

Method	`paras`	No summary
Method	`raw`	No summary
Method	`sents`	No summary
Method	`words`	No summary
Method	`_read_para_block`	Undocumented
Method	`_read_sent_block`	Undocumented
Method	`_read_word_block`	Undocumented
Instance Variable	`_para_block_reader`	Undocumented
Instance Variable	`_sent_tokenizer`	Undocumented
Instance Variable	`_word_tokenizer`	Undocumented

Inherited from CorpusReader (via PlaintextCorpusReader):

Method	`__repr__`	Undocumented
Method	`abspath`	Return the absolute path for the given file.
Method	`abspaths`	Return a list of the absolute paths for all fileids in this corpus; or for the given list of fileids, if specified.
Method	`citation`	Return the contents of the corpus citation.bib file, if it exists.
Method	`encoding`	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.
Method	`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).
Method	`fileids`	Return a list of file identifiers for the fileids that make up this corpus.
Method	`license`	Return the contents of the corpus LICENSE file, if it exists.
Method	`open`	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.
Method	`readme`	Return the contents of the corpus README file, if it exists.
Class Variable	`root`	Undocumented
Method	`_get_root`	Undocumented
Instance Variable	`_encoding`	The default unicode encoding for the fileids that make up this corpus. If `encoding` is None, then the file contents are processed using byte strings.
Instance Variable	`_fileids`	A list of the relative paths for the fileids that make up this corpus.
Instance Variable	`_root`	The root directory for this corpus.
Instance Variable	`_tagset`	Undocumented
