================================================================================
1. Training data attribution
================================================================================

The trained model files distributed with Kiwi (`models/`, and the model
archives published on the release page or through the language bindings) are
released under the Apache License, Version 2.0, together with the source code.

These models were trained on the following corpora, provided by the National
Institute of Korean Language (국립국어원):

  * 21세기 세종계획 말뭉치 (Sejong Corpus)
  * 모두의 말뭉치 (NIKL Corpora) — https://corpus.korean.go.kr

The models consist of morpheme dictionaries and n-gram statistics.
They do not contain, and cannot be used to reconstruct, the text of the source
corpora.

The source corpora themselves are NOT redistributed with Kiwi and remain
subject to the terms of their respective providers. If you need the corpora,
please obtain them directly from the National Institute of Korean Language.

The morpheme tag set used by Kiwi is based on the Sejong POS tag set, with some
tags added or modified by this project.
