description: Denna datamängd samlar den svenska testdatan för SemEval 2020 Task 1: Unsupervised Lexical Semantic Change Detection:

- Ett svenskt korpuspar (`corpus1/`, `corpus2/`)
- 31 lemmas som har blivit annoterad med lexikosemantisk förändring mellan de två korpusarna (`targets.txt`)
Vi samplar ur Kubhist2, en samling med dagstidningar digitaliserade av KB, och tillgängliga via Språkbankens infrastruktur Korp (Borin et al., 2012). Korpusen är tillgänglig genom en CC BY (attribution licens. 
Korpusen är lemmatiserad med hjälp av Korp. Varje ord har ersatts med ett lemma har ersatts om detta varit möjligt, annars har ordet behållts som det är (icke-lemmatiserat och utan att versaler har ändrade till gemener).
Kubhist-texterna innehåller en stor mängd OCR fel, speciellt den tidigare delkorpusen. Mer information om Kubhist och dess kvalité finns att finna i (Adesam et al., 2019).

description: This data collection contains the Swedish test data for SemEval 2020 Task 1: Unsupervised Lexical Semantic Change Detection:

- a Swedish text corpus pair (`corpus1/`, `corpus2/`)
- 31 lemmas which have been annotated for their lexical semantic change between the two corpora (`targets.txt`)
We sample from the KubHist2 corpus, digitized by the National Library of Sweden, and available through the Språkbanken corpus infrastructure Korp (Borin et al., 2012). The full corpus is available through a CC BY (attribution) license.
Each word for which the lemmatizer in the Korp pipeline has found a lemma is replaced with the lemma. In cases where the lemmatizer cannot find a lemma, we leave the word as is (i.e., unlemmatized, no lower-casing). KubHist contains very frequent OCR errors, especially for the older data.More detail about the properties and quality of the Kubhist corpus can be found in (Adesam et al., 2019).
