2. English Speller Database（ESDB）
本產品使用 ESDB（前稱 SCOWLv2）建立常用英文單字候選、詞形、詞性與常用度資料，並限制於經篩選的 ESDB size 50 以下美式英文資料。例句、繁體中文、主題標籤與其餘整理內容屬於本產品內容。 來源：English Speller Database。
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 deserves special credit as he is the author of 12dicts and a major contributor to ENABLE2K. In addition, he gave Kevin Atkinson an incredible amount of feedback and created a number of special lists in order to help improve the overall quality of ESDB.
