class documentation

class BracketParseCorpusReader(SyntaxCorpusReader): (source)

Known subclasses: nltk.corpus.reader.AlpinoCorpusReader, nltk.corpus.reader.CategorizedBracketParseCorpusReader

Constructor: BracketParseCorpusReader(root, fileids, comment_char, detect_blocks, ...)

Reader for corpora that consist of parenthesis-delineated parse trees, like those found in the "combined" section of the Penn Treebank, e.g. "(S (NP (DT the) (JJ little) (NN dog)) (VP (VBD barked)))".

Inherited from CorpusReader (via SyntaxCorpusReader):

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.

Parameters
root	The root directory for this corpus.
fileids	A list or regexp specifying the fileids in this corpus.
comment_char	The character which can appear at the start of a line to indicate that the rest of the line is a comment.
detect_blocks	The method that is used to find blocks in the corpus; can be 'unindented_paren' (every unindented parenthesis starts a new parse) or 'sexpr' (brackets are matched).
encoding	Undocumented
tagset	The name of the tagset used by this corpus, to be used for normalizing or converting the POS tags returned by the tagged_...() methods.
