Attribution & Licences

Everything on this site is built from open data. The vocabulary, the reading texts and the questions derived from them are published under CC BY-SA 4.0, inherited from Wiktionary and the wikis the reading texts come from. One of those, Hurraki, is CC BY-SA 3.0 DE, so each reading text records its own licence alongside its source. If you reuse any of it, keep this attribution reachable.

OpenSubtitles asks that work using the corpus link to opensubtitles.org and cite Lison & Tiedemann (2016), OpenSubtitles2016: Extracting Large Parallel Corpora from Movie and TV Subtitles (LREC). OPUS states that it does not own the underlying text and redistributes only what it believes it may.

Machine-generated content

Three things on this site were written by a language model rather than a person:

They are derivative of the wiki passages and the vocabulary examples they were built from, so they inherit CC BY-SA 4.0. Each reading text records the wiki it came from and that wiki's own licence.

The A1 reading texts are the exception. They are written for this site out of the A1 word list, and so are their translations, glossaries, grammar notes and comprehension questions. No wiki is behind them, and no model either.

They are machine-written and machine-checked, not reviewed by a teacher. The checks were real ones: comprehension items must quote the passage verbatim; gap-fill items must restore a word that genuinely occurs in the source; every word in a stem or option is checked against the vocabulary list up to that level; and a second model pass answered each item blind with the options already shuffled, with disagreements dropped rather than kept. But automated checks are not the same as review. Sample before putting any of it in front of learners, and treat anything that looks wrong as possibly wrong.
