Daily mention counts for twelve European politicians in Russian–language media (2025)

<p dir="ltr">This dataset contains daily counts of Russian-language documents mentioning twelve European politicians during 2025, together with the total number of documents processed on each day. The resulting share of documents mentioning each politician (the simple proportion of mentions) is the frequency-based measure compared with the Context-Aware Media Presence Index (CMPI) in the accompanying paper. Combined with the CMPI time series (doi.org/10.6084/m9.figshare.31094134), the data are sufficient to reproduce the comparison between the two measures, including the Chatterjee correlation coefficients.</p><p dir="ltr">Each row corresponds to a single politician on a single calendar date.

The dataset covers every day of 2025 for all twelve politicians, including days outside a politician's term of office.</p><p dir="ltr">Columns:</p><ul><li><b>politician</b>: Name of the politician.</li><li><b>report_date</b>: Calendar date of the observation (YYYY-MM-DD).</li><li><b>mentions</b>: Number of Russian-language documents processed on that date in which the politician is mentioned.</li><li><b>corpus_size</b>: Total number of Russian-language documents processed on that date (the same for all politicians on a given date).</li><li><b>proportion</b>: Share of documents mentioning the politician, in percent (100 × mentions / corpus_size), not rounded.</li></ul><p><br></p>
