class documentation

class RTECorpusReader(XMLCorpusReader): (source)

Constructor: RTECorpusReader(root, fileids, wrap_etree)

Corpus reader for corpora in RTE challenges.

This is just a wrapper around the XMLCorpusReader. See module docstring above for the expected structure of input documents.

Method	`pairs`	Build a list of RTEPairs from a RTE corpus.
Method	`_read_etree`	Map the XML input into an RTEPair.

Inherited from XMLCorpusReader:

Method	`__init__`	No summary
Method	`raw`	Undocumented
Method	`words`	Returns all of the words and punctuation symbols in the specified file that were in text nodes -- ie, tags are ignored. Like the xml() method, fileid can only specify one file.
Method	`xml`	Undocumented
Instance Variable	`_wrap_etree`	Undocumented

Inherited from CorpusReader (via XMLCorpusReader):

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

def pairs(self, fileids): (source) ¶

Build a list of RTEPairs from a RTE corpus.

Parameters
fileids	a list of RTE corpus fileids
Returns
list(RTEPair)	Undocumented

def _read_etree(self, doc): (source) ¶

Map the XML input into an RTEPair.

This uses the getiterator() method from the ElementTree package to find all the <pair> elements.

Parameters
doc	a parsed XML document
Returns
list(RTEPair)	Undocumented
