Out of the Imperial Anthologies of Waka-shū compiled from the Heian period through the Kamakura period, here we publically release under the title "Corpus of Historical Japanese Waka-shū Series" the data of Short Unit Word and Long Unit Word for waka-shū in the anthologies known as the Hachidai-shū (the first eight anthologies).
This corpus has the following characteristics:
Furthermore, please note that the language in the corpus is the original language of the classical texts, and modern translations are not provided.
The texts are based on the Nijūichidai-shū Shōho Era-print books that are items in the collection of the National Institute of Japanese Literature.
In principle the entirety of each text (kana preface, introductions to poems, poems, left-side notes) are taken as the objects of annotation. However, the following textual elements are excluded from the coverage in the corpus:
Please read the following abstract for this corpus before use:
Links from example sentences in the search results of the search tool "Chūnagon" over the data in the "Corpus of Historical Japanese Waka-shū Series" lead to pages with images of the original text containing the example sentences.
The first image link leads to facsimile images of the Nijūichidai-shū Shōho Era-print books that are items in the collection of the National Institute of Japanese Literature ("Pre-Modern Japanese Text Reader (International Image Interoperability Framework (IIIF) Curation Viewer)"). These images have been developed jointly by the National Institute for Japanese Literature and the Center for Open Data in the Humanities for online public release, and are available for reference free of charge.
As a second option, we provide an image link to page in question in the Maruzen eBook Library, a distribution service for digitized texts designed for institutions. This gives access to the text, its modern language translation, and notes. There is a charge for this service.
