Bases: MultiCorpus

__init__(languages='luo', version='v2', base_path=None, in_memory=True, **corpusargs)View on GitHub#

Initialize the Masakhane corpus available on masakhane-io/masakhane-ner.

It consists of ten African languages. Pass a language code or a list of language codes to initialize the corpus with the languages you require. If you pass “all”, all languages will be initialized. :version: Specifies version of the dataset. Currently, only “v1” and “v2” are supported, using “v2” as default. :type base_path: Union[str, Path, None] :param base_path: Default is None, meaning that corpus gets auto-downloaded and loaded. You can override this to point to a different folder but typically this should not be necessary. POS tags instead :type in_memory: bool :param in_memory: If True, keeps dataset in memory giving speedups in training.

Methods

__init__([languages, version, base_path, ...])

Initialize the Masakhane corpus available on masakhane-io/masakhane-ner.

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.
