class flair.datasets.sequence_labeling.NER_MULTI_CONER(task='multi', base_path=None, in_memory=True, **corpusargs)View on GitHub#

Bases: MultiFileColumnCorpus

__init__(task='multi', base_path=None, in_memory=True, **corpusargs)View on GitHub#

Download and Initialize the MultiCoNer corpus.

Parameters:
  • task (str) – either ‘multi’, ‘code-switch’, or the language code for one of the mono tasks.

  • base_path (Union[str, Path, None]) – Path to the CoNLL-03 corpus (i.e. ‘conll_03’ folder) on your machine POS tags or chunks respectively

  • in_memory (bool) – If True, keeps dataset in memory giving speedups in training.

Methods

__init__([task, base_path, in_memory])

Download and Initialize the MultiCoNer corpus.

add_label_noise(label_type, labels[, ...])

Generates uniform label noise distribution in the chosen dataset split.

downsample([percentage, downsample_train, ...])

Randomly downsample the corpus to the given percentage (by removing data points).

filter_empty_sentences()

A method that filters all sentences consisting of 0 tokens.

filter_long_sentences(max_charlength)

A method that filters all sentences for which the plain text is longer than a specified number of characters.

get_all_sentences()

Returns all sentences (spanning all three splits) in the Corpus.

get_label_distribution()

Counts occurrences of each label in the corpus and returns them as a dictionary object.

make_label_dictionary(label_type[, ...])

Creates a dictionary of all labels assigned to the sentences in the corpus.

make_tag_dictionary(tag_type)

Create a tag dictionary of a given label type.

make_vocab_dictionary([max_tokens, min_freq])

Creates a Dictionary of all tokens contained in the corpus.

obtain_statistics([label_type, pretty_print])

Print statistics about the corpus, including the length of the sentences and the labels in the corpus.
