| III. DATA | |
| Primary data* | Words (text) |
| Language* | Swedish |
| Dataset in numbers* | 14983 entries |
| Nature of the content* | Each entry in the resource contains a word, its part-of-speech tag (SUC-style), and a number of frequencies over different readability levels. Multi-word expressions are denoted by multiple words linked by underscores. |
| Format* | Comma-separated values (CSV) with the following columns: |
| word: a word in its lemma form | |
| POS: a part-of-speech tag in the SUC-format | |
| level1_freq - level6_freq (six headers): the dispersed frequency of the word in the given reading proficiency level | |
| total_freq: the adjusted frequency for the word across all reading proficiency levels | |
| n_level1 - n_level6 (six headers): raw frequency of the word in the given reading proficiency level | |
| n_total: raw frequency for the word across all reading proficiency levels | |
| Data source(s)* | The words are collected from 247 easy language books published by NyponVilja förlag. The books were OCR-scanned from PDF-format and preprocessed by the authors. Unfortunately, the book dataset is not publicly available due to copyright reasons. |

| IV. ETHICS AND CAVEATS | |
| Ethical considerations | The books contain words that when taken out of context can be seen as offensive. The authors have manually removed such entries, but can not guarantee that the resource is completely devoid of offensive words. |

| V. ABOUT DOCUMENTATION | |
| Data last updated* | 20220909 |
| Which changes have been made, compared to the previous version* | This version contain more entries than described in the original paper. This is due to two reasons: 1) An increased number of books available for the source material (from 247 to 280). 2) An updated method to filter out bad entries due to erraneous OCR-readings from the soruce PDFs. In practice, this means that the number of entries (unique words) of the resource is signifcantly larger (more than double the number of entries) in this version, since entries that only appear once in the source material are no longer discarded. However, for the total frequency counts for all entries, the difference between this updated version and the paper version is only around 2%. |
