type CHILDESCorpusReader

Parameters:

• root - A path pointer identifying the root directory for this corpus. If a string is specified, then it will be converted to a PathPointer automatically.
• fileids - A list of the files that make up this corpus. This list can either be specified explicitly, as a list of strings; or implicitly, as a regular expression over file paths. The absolute path for each file will be constructed by joining the reader's root to each file name.
• encoding - The default unicode encoding for the files that make up the corpus. encoding's value can be any of the following:
  • A string: encoding is the encoding name for all files.
  • A dictionary: encoding[file_id] is the encoding name for the file whose identifier is file_id. If file_id is not in encoding, then the file contents will be processed using non-unicode byte strings.
  • A list: encoding should be a list of (regexp, encoding) tuples. The encoding for a file whose identifier is file_id will be the encoding value for the first tuple whose regexp matches the file_id. If no tuple's regexp matches the file_id, the file contents will be processed using non-unicode byte strings.
  • None: the file contents of all files will be processed using non-unicode byte strings.
• tag_mapping_function - A function for normalizing or simplifying the POS tags returned by the tagged_words() or tagged_sents() methods.

Overrides: api.CorpusReader.__init__

(inherited documentation)

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.

Parameters:

• speaker - If specified, select specitic speakers defined in the corpus. Default is 'ALL'. Common choices are 'CHI' (all children) and 'MOT' (mothers)
• stem - If true, then use word stems instead of word strings.
• relation - If true, then return tuples of (stem, index, dependent_index)
• pos - If true, then return tuples of (stem, part_of_speech)
• strip_space - If true, then strip trailing spaces from word tokens. Otherwise, leave the spaces on the tokens.
• replace - If true, then use the replaced word instead of the original word (e.g., 'wat' will be replaced with 'watch')

Returns: list of str

the given file(s) as a list of words

Overrides: xmldocs.XMLCorpusReader.words

Parameters:

• speaker - If specified, select specitic speakers defined in the corpus. Default is 'ALL'. Common choices are 'CHI' (all children) and 'MOT' (mothers)
• stem - If true, then use word stems instead of word strings.
• relation - If true, then return tuples of (str,pos,relation_list). If there is manually-annotated relation info, it will return tuples of tuples of (str,pos,test_relation_list,str,pos,gold_relation_list)
• pos - If true, then return tuples of (stem, part_of_speech)
• strip_space - If true, then strip trailing spaces from word tokens. Otherwise, leave the spaces on the tokens.
• replace - If true, then use the replaced word instead of the original word (e.g., 'wat' will be replaced with 'watch')

Returns: list of (list of str)

the given file(s) as a list of sentences

Returns: list of dict

the given file(s) as a dict of (corpus_property_key, value)

Returns: list of dict

the given file(s) as a dict of (participant_propperty_key, value)

Parameters:

• month - If true, return months instead of year-month-date

Returns: list or int

the given file(s) as string or int

Returns: list of float

the given file(s) as a floating number
