    abstract = "FLORES+ is a collection of parallel datasets obtained by translation from originally English source texts. FLORES+ contains Norwegian translations for the two official written variants of Norwegian: Norwegian Bokm{\r{a}}l and Norwegian Nynorsk. However, the earliest Bokm{\r{a}}l version contained non-native-like mistakes, and even after a later revision, the dataset contained grammatical and lexical errors. This paper aims at correcting unambiguous mistakes, and thus creating a new version of the Bokm{\r{a}}l dataset. At the same time, we provide a translation into Radical Bokm{\r{a}}l, a sub-variety of Norwegian which is closer to Nynorsk in some aspects, while still being within the official norms for Bokm{\r{a}}l. We discuss existing errors and differences in the various translations and the corrections that we provide."

Language codes

• ISO 639-3: nob
• ISO 15924: Latn
• Glottocode: norw1259
• variant tag: radical (we had to introduce this field to disambiguate between the two Bokmål standards that share the same ISO codes and Glottocode).

Additional language information

The radical version is based on the official Bokmål dictionary: https://ordbokene.no/nob/ And guided by the Association of Radical Bokmål: https://bokmal.no/

Workflow

The data was corrected based on the most recent FLORES+ Bokmål translations. The corrections were done by two native Norwegian Bokmål writers with high proficiency in English, and with earlier experience in translation.
