About Song Types
Runosong types are scholarly classifications of poems by their content and function. The Finnish SKVR corpus assigns type labels (runotyypit) to 98.6% of its poems, and the Estonian ERAB corpus has type labels (laulutüübid) for 65.5% of its poems. Types include incantations, lullabies, epic narratives, wedding songs, and many more. English translations are generated using AI contextual translation.
How to Use
Search for types by name or English translation. Filter by language (Finnish/Estonian) and theme category. Click a type to see its geographic map, temporal distribution, co-occurring types, cross-language matches, and sample poems. Sort by frequency, alphabetically, or by geographic concentration.
Cross-Language Matching
Types are matched across Finnish and Estonian using semantic similarity of their AI-generated English translations, enhanced with keyword overlap, theme alignment, and surface-form cognate detection. Use the Cross-language pairs filter to browse unified FI–ET concept pairs with combined maps showing both corpora's geographic distribution. In the individual type view, up to 10 cross-language matches are shown with score bars.
Geographic Concentration (HHI)
The Herfindahl-Hirschman Index measures how concentrated a type is geographically. Low values (near 0) mean the type is widespread across many places; higher values mean it was collected primarily in a few areas.
Data Source
Song type labels come from SKVR metadata (Finnish) and ERAB metadata (Estonian). Types are shown in their original language; English translations are auto-generated word-by-word from the lemma glossary.
