Abstract* The Swedish Word-in-Context dataset provides a benchmark for evaluating distributional models of word meaning, in particular context-sensitive/dynamic models. Constructed following the principles of the (English) Word-in-Context dataset, SweWiC consists of 1000 sentence pairs, where each sentence in a pair contains an occurence of a potentially ambiguous focus word specific to that pair. The question posed to the tested system is whether these two occurrences represent instances of the same word sense. There are 500 same-sense pairs and 500 different-sense pairs.

Primary data* Text
Language* Swedish
Dataset in numbers* 1000 test items, 500 positive, 500 negative. Constructed from 560 focus word types: 263 types occurring in one test item, 156 in two , and 142 in three. The focus words are of the following parts of speech according to SALDO: 462 nouns, 351 verbs, 143 adjectives, 31 adverbs, 9 prepositions, 3 pronouns, and 1 interjection.
Nature of the content* Pairs of sentences with one highlighted word form in each sentence, such that these highlighted forms are linked to the same base form (but not necessarily in the same paradigm!). These pairs are accompanied with an indication of whether these forms in these contexts have the same sense (meaning) or not. The lexical resource SALDO is used to supply the senses and sense distinctions.
Format* JSON Lines, with 1 test item per line. Each item is given as a pair first word in context-second word in context, and a boolean saying whether the same sense is used. A word in context is given as a string for the context, and a combination of a string and string indices to locate the focus word. Indices start at 0, and refer to the NFKC-normalized unicode string. Metadata included for each item is intended for analysis, and not for use by the sense disambiguation system.
Data source(s)* SALDO v2.3 (CC BY 4.0, https://spraakbanken.gu.se/en/resources/saldo, see also [1]) is used to provide the sense inventory.
SALDO’s morphology (CC BY 4.0, https://spraakbanken.gu.se/en/resources/saldom) to ensure that the word forms in the sentences are possible word forms for the sense(s) involved in the test item.
SALDO examples (CC BY 4.0, https://spraakbanken.gu.se/en/resources/saldoe) and Eukalyptus v0.2.0 (mixed CC licenses, inclusion of sentences in SweWiC under CC BY 4.0 with permission, https://spraakbanken.gu.se/en/resources/eukalyptus; see [2] for the sense annotation in this corpus) are used as sources of sense annotated words in context.
Data collection method(s)* (See selection and filtering.)
Data selection and filtering* In the spirit of the design principles given in [3], the test items adhere to the following restrictions:
- all focus words are potentially ambiguous, even in the same-sense test items
- a focus word type occurs at most in three items in the test set, no combination of a focus word and a context is repeated
- the instances in both contexts in a test item are of the same part of speech (SALDO in principle allows for semantic base forms that cross part of speech), and SALDO’s morphology lists the word forms used in the contexts as possible realizations of the involved senses.
Data preprocessing* None.
Data labeling* Judgements about word senses are taken from resources with manual annotation of word senses, and therefore constitute gold-standard data.
Annotator characteristics(No additional annotation, that is, beyond the annotation done in the projects creating the data sources, was done in the compilation of SweWiC.)
Ethical considerations None to report.
