class SimpleLanguageModelingDatasetReader(DatasetReader):
 | def __init__(
 |     self,
 |     tokenizer: Tokenizer = None,

Reads sentences, one per line, for language modeling. This does not handle arbitrarily formatted text with sentences spanning multiple lines.

Parameters

  • tokenizer : Tokenizer, optional
    Tokenizer to use to split the input sentences into words or other kinds of tokens. Defaults to SpacyTokenizer().
  • token_indexers : Dict[str, TokenIndexer], optional
    Indexers used to define input token representations. Defaults to {"tokens": SingleIdTokenIndexer()}.
  • max_sequence_length : int, optional
    If specified, sentences with more than this number of tokens will be dropped.
  • start_tokens : List[str], optional (default = None)
    These are prepended to the tokens provided to the TextField.
  • end_tokens : List[str], optional (default = None)
    These are appended to the tokens provided to the TextField.
