Spell Checking Oriented Word Lists (SCOWL) Sun Feb 15 15:02:29 2015 -0500  by Kevin Atkinson (firstname.lastname@example.org) The SCOWL is a collection of word lists split up in various sizes, and other categories, intended to be suitable for use in spell checkers. However, I am sure it will have numerous other uses as well. The latest version can be found at http://wordlist.aspell.net/. The directory final/ contains the actual word lists broken up into various sizes and categories. The r/ directory contains Readmes from the various sources used to create this package. The misc/ contains a small list of taboo words, see the README file for more info. The speller/ directory contains scripts for creating spelling dictionaries for Aspell and Hunspell. The other directories contain the necessary information to recreate the word lists from the raw data. Unless you are interested in improving the words lists you should not need to worry about what's here. See the section on recreating the words lists for more information on what's there. Except for the special word lists the files follow the following naming convention: <spelling category>-<sub-category>.<size> Where the spelling category is one of english, american, british, british_z, canadian, variant_1, variant_2, variant_3, british_variant_1, british_variant_2, canadian_variant_1, canadian_variant_2, Sub-category is one of abbreviations, contractions, proper-names, upper, words And size is one of 10, 20, 35 (small), 40, 50 (medium), 55, 60, 70 (large), 80 (huge), 95 (insane) The special word lists follow are in the following format: special-<description>.<size> Where description is one of: roman-numerals, hacker The perl script "mk-list" can be used to create a word list of the desired size, its usage is: ./mk-list [-f] [-v#] <spelling categories> <size> where <spelling categories> is one of the above spelling categories (the english and special categories are automatically included as well as all sub-categories) and <size> is the desired size. The "-v" option can be used to also include the appropriate variants file up to level '#'. The normal output will be a sorted word list. If you rather see what files will be included, use the "-f" option. When manually combining the words lists the "english" spelling category should be used as well as one of "american", "british", "british_z" (british with ize spelling), or "canadian". Great care has been taken so that only one spelling for any particular word is included in the main list (with some minor exceptions). When two variants were considered equal I randomly picked one for inclusion in the main word list. Unfortunately this means that my choice in how to spell a word may not match your choice. If this is the case you can try including one of the "variant_1" spelling categories which includes most variants which are considered almost equal. The "variant_1" spelling category corresponds mostly to American variants, while the "british_variant_1" and "canadian_variant_1" are for British and Canadian variants, respectively. The "variant_2" spelling categories include variants which are also generally considered acceptable, and "variant_3" contains variants which are seldom used and may not even be considered correct. There is no "british_variant_3" or "canadian_variant_3" spelling category since the distinction would be almost meaningless. The "abbreviation" category includes abbreviations and acronyms which are not also normal words. The "contractions" category should be self explanatory. The "upper" category includes upper case words and proper names which are common enough to appear in a typical dictionary. The "proper-names" category includes all the additional uppercase words. Finally the "words" category contains all the normal English words. To give you an idea of what the words in the various sizes look like here is a sample of 25 random words found only in that size: 10: accidental accord claiming clears delete feeling former images inviting joins knock park patient pleasing presumably punctuation reaches realized rough sake signing square strong subject wasted 20: abusing acknowledging acorn ashcan characteristic consensus dawn dons evil fender intrinsic jury lighted mangle oar pinched poverty prefixing recipe resides scattered thirst voted vouch wet 35: antiquities bloodhound cherish compost czar deface deplored disgruntle franchising imperfections indecision invulnerable missive mosquitoes oxidizing powwowed pueblo readied retching slate sleigh smuggest stooped thuds toothpastes 40: anesthetizing bounciest cheapskate deathtrap disclaimers disheveled edifying expectantly galosh individualistic nerdiest pisses promoters reprized sorbets splashier splayed stoplight subordination technologist tiebreaker unplugging upliftings watchmakers website 50: automaton casuist chicle confabbing congaed demurring dermatologists gaiter lampblack misapprehend octogenarian overstock polity pompadour puffins reappointing reapportioned refracted retrenching rosewood scimitars semiprivate solemnizing ungracious unsnarling 55: bedsit chivy deadheaded demystifies denationalized factorizes fessed jailbirds lavs layabout marque numinous nutter ooh oversubscribe sackings spiderweb spiffing spousal sunbed toyboy toyboys vergers weedkiller wienie 60: assayers barbarianism casabas charterers commodiously corbels cretinism deist economizers foggily gimping heavers jadedness kindheartedly moldboard monopolizer mullein nonperishable nonphysically phylogeny recrossed reformulations senor senors wagerer 70: cancelate clary clavus cleistogamy colicroot crus digitizers discants effectivities fusser ganjas inhume irresoluble lehr moorworts nauseation orthoclase reoccurrence slimmish stupe summerwood tamis turdine unnavigable verist 80: acyloin amidines astare aventailes backloads bathybiuses birliemen crowbill gawkinesses glyptographers induvial intermeddling jouking lah lathyrism lavras miracidial pandation pseudoephedrine standoffishly teschenite tirrivees truckline uncake vanitories 95: adion autostoper avives bacteriocidal cespititous changedale copperwing eglestonite electrocoating ganglioneuron hapiton leukocythemia mechoacan paedometer preinitializes reflationism straighthead subpackage undiscardable unitiveness unpeddled unvoraciously ventrosity viveur wallowishly And here is a count on the number of words in each spelling category (american + english spelling category): Size Words Names Running Total % 10 4,427 13 4,440 0.7 20 8,122 0 12,562 1.9 35 37,256 222 50,040 7.6 40 6,846 491 57,377 8.7 50 25,122 18,215 100,714 15.3 55 6,509 0 107,223 16.3 60 13,754 704 121,681 18.5 70 35,696 7,940 165,317 25.1 80 144,402 33,371 343,090 52.2 95 227,745 86,667 657,502 100.0 (The "Words" column does not include the name count.) Size 35 is the recommended small size, 50 the medium and 70 the large. For spell checking I recommend using 60. Sizes 70 and below contain words found in most dictionaries while the 80 size contains all the strange and unusual words people like to use in word games such as Scrabble (TM). While a lot of the words in the 80 size are not used very often, they are all generally considered valid words in the English language. The 95 contains just about every English word in existence and then some. Many of the words at the 95 level will probably not be considered valid English words by most people. I use the 60 size for the English dictionary for Aspell, and I don't recommend anyone use levels above 70 for spell checking. Levels above 70 contain rarely used words which can hide misspellings of similar more commonly used words. For example the word "ort" can hide a common typo of "or". No one should need to use a size larger than 80, the 95 size is labeled insane for a reason. Accents are present on certain words such as café in iso8859-1 format. CHANGES: From Version 2015.01.28 to 2015.02.15 (February 15, 2015) Added a large number of neologisms (newly invented words) such as "selfie" and "smartwatch" thanks to Alan Beale. Various other new words. Clean up the special-hacker category by removing some words that didn't exist is the Google Book's Corpus (1980 - 2008) and originated from the "Unofficial Jargon File Word Lists". From Version 2014.11.17 to 2015.01.28 (January 28, 2015) Various new words, many from analyzing the Google Book's Corpus (1980 - 2008). See http://app.aspell.net/lookup-freq. Moved some uncommon words that can easily hide a misspelling of a more common word to level 70. (calender, adrenalin and Joesph) Removed several -er and -est forms from adjectives that were so uncommon that they were not found anywhere is the Google Book's Corpus (1980 - 2008). From Version 2014.08.11.1 to 2014.11.17 (November 17, 2014) Various new words. Fix typo in Hunspell readme. From Version 2014.08.11 to 2014.08.11.1 (August 13, 2014) Forgot to mention this important change from 7.1 to 2014.08.11: Shifted the variant levels up by one: variant_0 is now variant_1, variant_1 is now variant_2, and variant_2 is now variant_3. Other minor fixes in this README. No changes to the contents of the lists. From Revision 7.1 to Version 2014.08.11 (August 11, 2014) Added some missing possessive forms. Added some new words and proper names. Clean up the categories (words, upper, proper-names etc) so that they are more accurate. Convert documentation to UTF-8. For now, the wordlist are still in ISO-8859-1 to prevent compatibility problems. Add schema and scripts for creating a SQLite database from SCOWL. Add some utility and library functions using them. This database is used by the new web app's (http://app.aspel.net/lookup & create). Enhance speller/make-hunspell-dict. The biggest improvement is that it that it now generates several more dictionaries in addition to the official ones. These additional dictionaries are ones for British English and larger dictionaries that include up to SCOWL size 70. From Revision 7 to 7.1 (January 6, 2011) Updated to revision 5.1 of Varcon which corrected several errors. Fixed various problems with the variant processing which corrected a few more errors. Added several now common proper names and some other words now in common use. Include misc/ and speller/ directory which were in SVN but left out of the release tarball. Other minor fixes, including some fixes to the taboo word lists. From Revision 6 to 7 (December 27, 2010) Updated to revision 5.0 of Varcon which corrected many errors, especially in the British and Canadian spelling categories. Also added new spelling categories for the British and Canadian spelling variants and separated them out from the main variant_* categories. Moved Moby names lists (3897male.nam 4946fema.len 21986na.mes) to 95 level since they contain too many errors and rare names. Moved frequently class 0 from Brian Kelk's Wordlist from level 60 to 70, and also filter it with level 80 due to, too many misspellings. Many other minor fixes. From Revision 5 to 6 (August 10, 2004) Updated to version 4.0 of the 12dicts package. Included the 3esl, 2of4brif, and 5desk list from the new 12dicts package. The 3esl was included in the 40 size, the 2of4brif in the 55 size and the 5desk in the 70 size. Removed the Ispell word list as it was a source of too many errors. This eliminated the 65 size. Removed clause 4 from the Ispell copyright with permission of Geoff Kuenning. Updated to version 4.1 of VarCon. Added the "british_z" spelling category which is British using the "ize" spelling. From Revision 4a to 5 (January 3, 2002) Added variants that were not really spelling variants (such as forwards) back into the main list. Fixed a bug which caused variants of words to incorrectly appear in the non-variant lists. Moved rarely used inflections of a word into higher number lists. From 7.1 Shifted the variant levels so that level 0 is now 1, level 1 now 2, and level 2 now 3. Added other inflections of a words based on the following criteria If the word is in the base form: only include that word. If the word is in a plural form: include the base word and the plural If the word is a verb form (other than plural): include all verb forms If the word is an ad* form: include all ad* forms If the word is in a possessive form: also include the non-possessive Updated to the latest version of many of the source dictionaries. Removed the DEC Word List due to the questionable licence and because removing it will not seriously decrease the quality of SCOWL (there are a few less proper names). From Revision 4 to 4a (April 4, 2001) Reran the scripts on a never version of AGID (3a) which fixes a bug which caused some common words to be improperly marked as variants. From Revision 3 to 4 (January 28, 2001) Split the variant "spelling category" up into 3 different levels. Added words in the Ispell word list at the 65 level. Other changes due to using more recent versions of various sources included a more accurate version of AGID thanks to the work of Alan Beale From Revision 2 to 3 (August 18, 2000) Renamed special-unix-terms to special-hacker and added a large number of commonly used words within the hacker (not cracker) community. Added a couple more signature words including "newbie". Minor changes due to changes in the inflection database. From Revision 1 to 2 (August 5, 2000) Moved the male and female name lists from the mwords package and the DEC name lists form the 50 level to the 60 level and moved Alan's name list from the 60 level to the 50 level. Also added the top 1000 male, female, and last names from the 1990 Census report to the 50 level. This reduced the number of names in the 50 level from 17,000 to 7,000. Added a large number of Uppercase words to the 50 level. Properly accented the possessive form of some words. Minor other changes due to changes in my raw data files which have not been released yet.

There were many many sources in total, but any text marked "copyright" was avoided. Locally-written documentation was one source. An earlier version of the list resided in a filespace called PUBLIC on the University mainframe, because it was considered public domain. Date: Tue, 11 Jul 2000 19:31:34 +0100 > So are you saying your word list is also in the public domain? That is the intention. The 20 level includes frequency classes 7-15 from Brian's word list. The 35 level includes frequency classes 2-6 and words appearing in at least 11 of 12 dictionaries as indicated in the 12Dicts package. All words from the 12Dicts package have had likely inflections added via my inflection database. The 12Dicts package and Supplement is in the Public Domain.

The 40 level includes words from Alan's 3esl list found in version 4.0 of his 12dicts package. Like his other stuff the 3esl list is also in the public domain. The 50 level includes Brian's frequency class 1, words appearing in at least 5 of 12 of the dictionaries as indicated in the 12Dicts package, and uppercase words in at least 4 of the previous 12 dictionaries. A decent number of proper names is also included: The top 1000 male, female, and Last names from the 1990 Census report; a list of names sent to me by Alan Beale; and a few names that I added myself. Finally a small list of abbreviations not commonly found in other word lists is included. The name files form the Census report is a government document which I don't think can be copyrighted. The file special-jargon.50 uses common.lst and word.lst from the "Unofficial Jargon File Word Lists" which is derived from "The Jargon File". All of which is in the Public Domain. This file also contain a few extra UNIX terms which are found in the file "unix-terms" in the special/ directory. The 55 level includes words from Alan's 2of4brif list found in version 4.0 of his 12dicts package. Like his other stuff the 2of4brif is also in the public domain. The 60 level includes all words appearing in at least 2 of the 12 dictionaries as indicated by the 12Dicts package. The 70 level includes Brian's frequency class 0 and the 74,550 common dictionary words from the MWords package. The common dictionary words, like those from the 12Dicts package, have had all likely inflections added. The 70 level also included the 5desk list from version 4.0 of the 12Dics package which is in the public domain. The 80 level includes the ENABLE word list, all the lists in the ENABLE supplement package (except for ABLE), the "UK Advanced Cryptics Dictionary" (UKACD), the list of signature words from the YAWL package, and the 10,196 places list from the MWords package. The ENABLE package, mainted by M\Cooper <firstname.lastname@example.org>, is in the Public Domain: The ENABLE master word list, WORD.LST, is herewith formally released into the Public Domain. Anyone is free to use it or distribute it in any manner they see fit. No fee or registration is required for its use nor are "contributions" solicited (if you feel you absolutely must contribute something for your own peace of mind, the authors of the ENABLE list ask that you make a donation on their behalf to your favorite charity).

The variant word lists were created from a list of variants found in the 12dicts supplement package as well as a list of variants I created myself. The Readmes for the various packages used can be found in the appropriate directory under the r/ directory. FUTURE PLANS: The process of "sort"s, "comm"s, and Perl scripts to combine the many word lists and separate out the variant information is inexact and error prone. The whole things needs to be rewritten to deal with words in terms of lemmas. When the exact lemma is not known a best guess should be made. I'm not sure what form this should be in. I originally thought this should be some sort of database, but maybe I should just slurp all that data into memory and process it in one giant perl script. With the amount of memory available these days (at least 2 GB, often 4 GB or more) this should not really be a problem. In addition, there is a very nice frequency analyze of the BNC corpus done by Adam Kilgarriff. Unlike Brain's word lists the BNC lists include part of speech information. I plan on somehow using these lists as Adam Kilgarriff has given me the OK to use it in SCOWL. These lists will greatly reduce the problem of inflected forms of a word appearing at different levels due to the part-of-speech information. There is frequency information for some other corpus such as COCA (Corpus of Contemporary American English) and ANS (American National Corpus) which I might also be able to use. The former will require permission, and the latter is of questionable quality. RECREATING THE WORD LISTS: In order to recreate the word lists you need a modern version of Perl, bash, the traditional set of shell utilities, a system that supports symbolic links, and quite possibly GNU Make. The easiest way to recreate the word lists is to checkout the corresponding Git version (see the version string at the start of the file) and simply type "make" (see http://wordlist.aspell.net). You can try to download all the pieces manually, but this method is not no longer tested nor supported. The src/ directory contains the numerous scripts used in the creation of the final product. The r/ directory contains the raw data used to create the final product. If you checkout from Git this directory should be populated automatically for you. If you insist on doing it the hard way see the README file in the r/ directory for more information. The l/ directory contains symbolic links used by the actual scripts. Finally, the working/ directory is where all the intermittent files go that are not specific to one source.
