Dataset Card for Kelly

Keywords for Language Learning for Young and adults alike

Dataset Summary

The Swedish Kelly list is a freely available frequency-based vocabulary list that comprises general-purpose language of modern Swedish. The list was generated from a large web-acquired corpus (SweWaC) of 114 million words dating from the 2010s. It is adapted to the needs of language learners and contains 8,425 most frequent lemmas that cover 80% of SweWaC.

Dataset Structure

Data Instances

Here is a sample of the data:

{
    'id': 190,
    'raw_frequency': 117835.0,
    'relative_frequency': 1033.61,
    'cefr_level': 'A1',
    'source': 'SweWaC',
    'marker': 'en',
    'lemma': 'dag',
    'pos': 'noun-en',
    'examples': 'e.g. god dag'
}

This can be understood as:

The common noun "dag" ("day") has a rank of 190 in the list. It was used 117,835 times in SweWaC, meaning it occured 1033.61 times per million words. This word is among the most important vocabulary words for Swedish language learners and should be learned at the A1 CEFR level. An example usage of this word is the phrase "god dag" ("good day").

Data Fields

• id: The row number for the data entry, starting at 1. Generally corresponds to the rank of the word.
• raw_frequency: The raw frequency of the word.
• relative_frequency: The relative frequency of the word measured in number of occurences per million words.
• cefr_level: The CEFR level (A1, A2, B1, B2, C1, C2) of the word.
• source: Whether the word came from SweWaC, translation lists (T2), or was manually added (manual).
• marker: The grammatical marker of the word, if any, such as an article or infinitive marker.
• lemma: The lemma of the word, sometimes provided with its spelling or stylistic variants.
• pos: The word's part-of-speech.
• examples: Usage examples and comments. Only available for some of the words.

Manual entries were prepended to the list, giving them a higher rank than they might otherwise have had. For example, the manual entry "Göteborg ("Gothenberg") has a rank of 20, while the first non-manual entry "och" ("and") has a rank of 87. However, a conjunction and common stopword is far more likely to occur than the name of a city.

Data Splits

There is a single split, train.

Dataset Creation

Please refer to the article Corpus-based approaches for the creation of a frequency based vocabulary list in the EU project KELLY – issues on reliability, validity and coverage for information about how the original dataset was created and considerations for using the data.

The following changes have been made to the original dataset:

• Changed header names.
• Normalized the large web-acquired corpus name to "SweWac" in the source field.
• Set the relative frequency of manual entries to null rather than 1000000.
