Initialize ZELDA Entity Linking corpus.

introduced in “ZELDA: A Comprehensive Benchmark for Supervised Entity Disambiguation” (Milich and Akbik, 2023). When calling the constructor for the first time, the dataset gets automatically downloaded.

Parameters:

base_path (Union[str, Path], optional) – 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 (bool) – If True, keeps dataset in memory giving speedups in training.
column_format (Dict[int, str]) – The column-format to specify which columns correspond to the text or label types.

Initialize Aquaint Entity Linking corpus.

introduced in: D. Milne and I. H. Witten. Learning to link with wikipedia https://www.cms.waikato.ac.nz/~ihw/papers/08-DNM-IHW-LearningToLinkWithWikipedia.pdf . If you call the constructor the first time the dataset gets automatically downloaded and transformed in tab-separated column format (aquaint.txt).

Parameters:

base_path (Union[str, Path], optional) – 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 (bool) – If True, keeps dataset in memory giving speedups in training.
agreement_threshold (float) – Some link annotations come with an agreement_score representing the agreement from the human annotators. The score ranges from lowest 0.2 to highest 1.0. The lower the score, the less “important” is the entity because fewer annotators thought it was worth linking. Default is 0.5 which means the majority of annotators must have annoteted the respective entity mention.
sentence_splitter (SentenceSplitter) – The sentencesplitter that is used to split the articles into sentences.

wiki_language (str) – specify the language of the names of the wikipedia pages, i.e. which language version of Wikipedia URLs to use. Since the text is in german the default language is German.

Initialize a custom corpus with any Word Sense Disambiguation (WSD) datasets in the UFSAC format.

see getalp/UFSAC.

If the constructor is called for the first time the data is automatically downloaded and transformed from xml to a tab separated column format. Since only the WordNet 3.0 version for senses is consistently available for all provided datasets we will only consider this version. Also we ignore the id annotation used in datasets that were originally created for evaluation tasks

Parameters:

filenames (Union[str, List[str]]) – Here you can pass a single datasetname or a list of datasetnames. The available names are: ‘masc’, ‘omsti’, ‘raganato_ALL’, ‘raganato_semeval2007’, ‘raganato_semeval2013’, ‘raganato_semeval2015’, ‘raganato_senseval2’, ‘raganato_senseval3’, ‘semcor’, ‘semeval2007task17’, ‘semeval2007task7’, ‘semeval2013task12’, ‘semeval2015task13’, ‘senseval2’, ‘senseval2_lexical_sample_test’, ‘senseval2_lexical_sample_train’, ‘senseval3task1’, ‘senseval3task6_test’, ‘senseval3task6_train’, ‘trainomatic’, ‘wngt’,
base_path (Union[str, Path, None]) – You can override this to point to a specific folder but typically this should not be necessary.
in_memory (bool) – If True, keeps dataset in memory giving speedups in training.
cut_multisense (bool) – Boolean that determines whether the wn30_key tag should be cut if it contains multiple possible senses. If True only the first listed sense will be used and the suffix ‘_cut’ will be added to the name of the CoNLL file. Otherwise the whole list of senses will be detected as one new sense. The default is True.
columns – Columns to consider when loading the dataset. You can add 1: “lemma” or 2: “pos” to the default dict {0: “text”, 3: “sense”} if you want to use additional pos and/or lemma for the words.
banned_sentences (Optional[List[str]]) – Optionally remove sentences from the corpus. Works only if in_memory is true
sample_missing_splits_in_multicorpus (Union[bool, str]) – Whether to sample missing splits when loading the multicorpus (this is redundant if sample_missing_splits_in_each_corpus is True)
sample_missing_splits_in_each_corpus (Union[bool, str]) – Whether to sample missing splits when loading each single corpus given in filenames.
use_raganato_ALL_as_test_data (bool) – If True, the raganato_ALL dataset (Raganato et al. “Word Sense Disambiguation: A unified evaluation framework and empirical compariso”) will be used as test data. Note that the sample_missing_splits parameters are set to ‘only_dev’ in this case if set to True.
name (str) – Name of your corpus
