English Speller Database (ESDB)

Source: github.com/en-wl/wordlist

NYNR's ESDB-derived assets are generated from ESDB v2. The complete upstream copyright notice used by NYNR is reproduced below.

Copyright 2000-2026 by Kevin Atkinson

Permission to use, copy, modify, distribute, and sell any part of the English
Speller Database (ESDB, previously known as SCOWLv2), or word lists
created from it, is hereby granted without fee, provided that the above
copyright notice appears in all copies and that both the above copyright
notice and this notice appear in supporting documentation.  Kevin Atkinson
makes no representations about the suitability of this database for any
purpose.  It is provided "as is" without express or implied warranty.

ESDB is derived from many sources, most of which are in the Public Domain.
Data from the Corpus of Contemporary American English (COCA) was also used.

All data from COCA comes from 3-gram data that is not freely available;
however, the usage is within the rights given by the NDA that was signed when
purchasing the data.  More information on COCA is available at
https://www.english-corpora.org/coca/.

The primary source of words for ESDB comes from 12dicts and ENABLE2K.  Both
are in the Public Domain, but Alan Beale <[email protected]> deserves special
credit as he is the author of 12dicts and a major contributor to ENABLE2K.  In
addition, he gave me an incredible amount of feedback and created a number of
special lists in order to help improve the overall quality of ESDB.

===

If you are using an official speller dictionary created by ESDB that is not
Australian English, then no additional copyright applies and including the
notice before the === is sufficient.

If you are using the Australian English dictionary or a wordlist that uses the 'D'
SPELLING code and/or the 'AU' REGION code, the copyright after '=== AU' applies.

If you are using a generated word list larger than 80, the copyright
after '=== UKACD' applies.

If you are distributing the database or results from the
database that is not a speller dictionary or generated word list, then both
copyrights may apply depending on the parts you use.  In addition, the WordNet
copyright MIGHT apply as WordNet was one of many sources used for the initial
POS assignment.

=== AU

The initial information for Australian English comes from Benjamin Titze:

  representations about the suitability of this array for any
  purpose. It is provided "as is" without express or implied warranty.

  There are no other restrictions: I would like to see the list
  distributed as widely as possible.

O conjunto lexical em português do NYNR é derivado do arquivo WORDmaster.txt na revisão fixada 315e063da1f89c89e2097c6e72428ebefb9ab1d1.

O PortiLexicon-UD é de Lucelene Lopes, Magali Duran, Paulo Fernandes e Thiago Pardo. A referência do projeto é:

FrequencyWords - Português Brasileiro

Fonte: github.com/hermitdave/FrequencyWords

O NYNR usa a lista de frequência pt_br_full.txt de 2018 na revisão fixada 525f9b560de45753a5ea01069454e72e9aa541c6. O FrequencyWords declara seu conteúdo gerado sob a Creative Commons Attribution-ShareAlike 4.0 International (CC BY-SA 4.0). As listas de 2018 são derivadas do OpenSubtitles 2018.

Os dados de frequência são associados à grafia original do PortiLexicon antes da remoção de diacríticos pelo NYNR. A frequência determina a grafia representativa usada nas chaves de jogo quando várias grafias portuguesas se tornam iguais depois da remoção dos acentos. Evidência positiva no FrequencyWords também forma a base do vocabulário comum em português.

O dicionário em português resultante, a análise de candidatos, o conjunto final da Palavra do Dia, o calendário determinístico e os dados de execução derivados relacionados são distribuídos sob CC BY-SA 4.0.

Esta declaração de compartilhamento pela mesma licença se aplica aos dados derivados identificados, não ao código do aplicativo NYNR nem a recursos não relacionados.

wordfreq - classificação secundária

Fonte: github.com/rspeer/wordfreq

O NYNR usa wordfreq 3.1.1 como evidência secundária apenas para palavras portuguesas aceitas pelo PortiLexicon que não aparecem no FrequencyWords. Entradas com frequência Zipf em português de pelo menos 3,00 são resgatadas para o vocabulário comum antes que o restante seja classificado como Palavras Proibidas.

O software wordfreq é redistribuível sob a licença Apache. Os dados de frequência incluídos podem ser redistribuídos sob a Creative Commons Attribution-ShareAlike 4.0.

A classificação derivada se aplica aos dados identificados, não ao código do aplicativo NYNR nem a recursos não relacionados.
