The study applies Market Basket Analysis and Keymorph Analysis to analyze the articles related to Svalbard published in a sample of Russian mainstream federal and north-western regional media outlets produced between 2010 and 2021. The data for Market Basket Analysis is divided into six target subcorpora: Federal 2010-2013, Regional 2010-2013, Federal 2014-2017, Regional 2014-2017, Federal 2018-2021, and Regional 2018-2021. The data for Keymorph Analysis consists of six target subcorpora: Federal 2010-2013, Regional 2010-2013, Federal 2014-2017, Regional 2014-2017, Federal 2018-2021, and Regional 2018-2021. The data for Keymorph Analysis are the texts containing the keyword 'Spitsbergen' obtained from the data for Market Basket Analysis. Market Basket Analysis is used to retrieve Associative Arrays consisting of various keywords for the keyword meaning 'Spitsbergen'. Keymorph Analysis examines the prominence of the grammatical cases of nouns meaning 'Russia', 'Norway', and 'Spitsbergen'. The dataset includes: 1) the R code for keyword analysis (keywords serve as an input for Market Basket Analysis); 2) lists of keywords obtained from six target subcorpora Federal 2010-2013, Regional 2010-2013, Federal 2014-2017, Regional 2014-2017, Federal 2018-2021, and Regional 2018-2021; 3) the R code for Market Basket Analysis; 4) examples with the nouns meaning 'Russia', 'Norway', and 'Spitsbergen' extracted from six target subcorpora Federal 2010-2013, Regional 2010-2013, Federal 2014-2017, Regional 2014-2017, Federal 2018-2021, and Regional 2018-2021 and annotated according to the grammatical cases of these nouns as well as the semantic meanings of the cases; 5) the calculated difference index (DIN) values for the grammatical cases of the nouns meaning 'Russia', 'Norway', and 'Spitsbergen'. The DIN was used in Keymorph Analysis as the effect size metric; 6) the R code for creation of the bar chart with DIN* values for the grammatical cases of the nouns meaning 'Russia', 'Norway', and 'Spitsbergen'.
