nltk.corpus.reader.tagged.TaggedCorpusView

Class TaggedCorpusView

object --+ | util.AbstractLazySequence --+ | util.StreamBackedCorpusView --+ | TaggedCorpusView

A specialized corpus view for tagged documents. It can be customized via flags to divide the tagged corpus documents up by sentence or paragraph, and to include or omit part of speech tags. TaggedCorpusView objects are typically created by TaggedCorpusReader (not directly by nltk users).

source code

Create a new corpus view, based on the file filename, and read with block_reader. See the class documentation for more information.

Parameters:

filename - The path to the file that is read by this corpus view. filename can either be a string or a PathPointer.
startpos - The file position at which the view will start reading. This can be used to skip over preface sections.
encoding - The unicode encoding that should be used to read the file's contents. If no encoding is specified, then the file's contents will be read as a non-unicode string (i.e., a str).

Overrides: util.StreamBackedCorpusView.__init__

read_block(self, stream)

source code

Reads one paragraph at a time.

Parameters:

stream - an input stream

Returns: list of any

a block of tokens from the input stream
