Initialize the CLEF-HIPE 2022 NER dataset.
The first time you call this constructor it will automatically download the specified dataset (by given a language). :dataset_name: Supported datasets are: ajmc, hipe2020, letemps, newseye, sonar and topres19th. :language: Language for a supported dataset. :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. :in_memory: If True, keeps dataset in memory giving speedups in training. :version: Version of CLEF-HIPE dataset. Currently only v1.0 is supported and available. :branch_name: Defines git branch name of HIPE data repository (main by default). :dev_split_name: Defines default name of development split (dev by default). Only the NewsEye dataset has currently two development splits: dev and dev2. :add_document_separator: If True, a special document seperator will be introduced. This is highly recommended when using our FLERT approach. :sample_missing_splits: If True, data is automatically sampled when certain data splits are None. :preproc_fn: Function that is used for dataset preprocessing. If None, default preprocessing will be performed.
Methods
__init__
(dataset_name, language[, ...])Initialize the CLEF-HIPE 2022 NER dataset.
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.
