Data & licences

Semantide combines independent open-language projects into a searchable learning experience. Those projects are not affiliated with, and do not endorse, Semantide or lyricalearn.

EDRDG dictionary files

Word, name, kanji, and radical records are adapted from JMdict, JMnedict, KANJIDIC2, KRADFILE, and RADKFILE. Copyright belongs to James William Breen and the Electronic Dictionary Research and Development Group (EDRDG); RADKFILE2 and KRADFILE2 are copyright Jim Rose. These files are used under the EDRDG licence and applicable CC BY-SA 4.0 terms. Semantide consumes JSON conversions published by jmdict-simplified, indexes and normalizes the records, and makes the adapted dictionary data available through search and the JSON endpoint. Those adaptations remain subject to the source terms.

Tatoeba examples

Example sentence text is sourced from Tatoeba. Tatoeba's downloadable sentence data is generally available under CC BY 2.0 FR, with CC0 and public-domain subsets identified by Tatoeba. Individual examples link back to their source where an identifier is available. Semantide does not redistribute Tatoeba audio.

KanjiVG diagrams

Stroke-order diagrams are derived from KanjiVG, copyright Ulrich Apel and contributors, under CC BY-SA 3.0.

JLPT reference data

Word-level classifications use Bluskyo's JSON conversion of Jonathan Waller's JLPT Resources. Waller's lists are offered under Creative Commons Attribution; the conversion code and formatting are MIT-licensed. Kanji-level classifications also use David Luzgouveia's MIT-licensed kanji-data, which identifies Waller's lists as its JLPT source. These classifications are unofficial study aids—the JLPT does not publish an official post-2010 vocabulary or kanji list.

WaniKani level metadata

Optional level numbers are derived from WaniKani subject metadata through David Luzgouveia's kanji-data and fasiha's ebieki. WaniKani is a trademark of Tofugu LLC. Semantide and lyricalearn are not affiliated with or endorsed by Tofugu. Semantide does not reproduce WaniKani mnemonics or lesson text.
