ParkeNYU Posted June 12, 2014 at 06:23 AM Report Share Posted June 12, 2014 at 06:23 AM PRime (ParseRime IME), or 析韻輸入法, is a diaphonemic pan-topolectal input method based on the Yunjing (韻鏡), the oldest known rime table reflecting the literary language of the Tang-Song period (Late Middle Chinese). Naturally, considering the evolution of the modern topolects, varying degrees of training and experience are required to master this input method depending upon the number of topolects with which a given user is acquainted. As Middle Chinese is the greatest common factor of most Chinese topolects and Sino-xenic lexicons (primarily in the literary register), it is the natural choice of foundation for a universal diaphonemic input method. When difficulties in syllable construction arise, the information required to construct a given character can be found in a number of Chinese and Sino-xenic resources. This input method may be seen as a diaphonemic analogy to graphical input methods like Cangjie, Wubi, and Dayi, all of which also embody a pan-topolectal approach. PRime boasts the highest degree of accuracy–with the lowest number of keystrokes–of any Chinese phonetic input method, as the diaphonemic description is so narrow that the character-candidate lists are kept remarkably short; within those lists, commonly used characters represent only a small fraction of the total number of characters available. The project began on the 30th of May, 2014. The typist compiles a string of four Middle Chinese syllabic properties to construct each desired character: initial (聲母x36), division/rounding (等呼x4), tone (聲調x4), and rime-group (韻攝x20), collectively termed 析韻根字 or 母呼聲攝 (with a nicely round figure of sixty-four symbols in total). The extended rime-group set of PRime contains four additional members outside of the classical set in order to fully distinguish divisions I (一等) and II (二等) within the 'outer' (外轉) rime-groups. As divisions III and IV have been merged in this system–with the distinction between divisions I and II already accounted for–the remaining four members of the 'division/rounding' category will henceforth be referred to as 'medials'. The keyboard itself is arranged in two layers, each containing a chart of syllabic properties. The Initial layer (母層)–as the name implies–carries the initials, whilst the Final layer (韻層) carries the medials, tones, and rime-groups (collectively comprising the finals). On the Initial layer, each column represents a classical initial-group roughly corresponding to the place of articulation (聲系), whilst each row indicates a voicing/aspiration status roughly corresponding to the manner of articulation (清濁). On the Final layer, each column represents a coda (韻尾), whilst each row represents a nucleus (韻腹); naturally, this arrangement does not apply to the medial (等呼/韻頭) and tone (聲調) keys, which are placed in the central region of the keyboard. Once a key on the Initial layer is pressed, the keyboard immediately shifts to the Final layer; once a rime-group key is pressed (following the optional selections of medial and tone), the resulting character is entered automatically, and the keyboard reverts to the Initial layer, allowing the process to begin a new cycle for the next desired character. When no medial or tone is specified, open/unrounded (開呼) and even/level/flat (平聲) serve as their respective default values, as these values are held by the greatest number of characters in the Chinese lexicon; this arrangement allows for as few as two keystrokes per character and no more than four (not including the SHIFT key, which reveals the ten 全濁 voiced initials). There is also a 'phonetic component' mode, which allows the user to output the desired character by entering the value of its phonetic component in citation form (reflecting the component's pronunciation when used independently). 2 Quote Link to comment Share on other sites More sharing options...
Takeshi Posted June 12, 2014 at 06:49 PM Report Share Posted June 12, 2014 at 06:49 PM This is a brilliant idea! If it is possible to get working on ibus for Linux (I don't see why not, you just need to set up tables to work with ibus-table or something), I would definitely try this out! I am currently a happy Cangjie user so I don't really need a new IME for productivity purposes, but I think this input method sounds like a fun pedagogical exercise—what better way to remember middle chinese rimes in your head? 2 Quote Link to comment Share on other sites More sharing options...
ParkeNYU Posted June 12, 2014 at 08:37 PM Author Report Share Posted June 12, 2014 at 08:37 PM Takeshi, thank you for the kind words. Currently, I am programming this IME using OpenVanilla, which is a Macintosh-exclusive application (and a frustratingly limited one, at that). However, once I either brush up on my programming chops or find a talented software engineer with whom I may collaborate (whichever comes first), this system can be easily tailored for cross-platform implementation. Obviously, my initial post does not offer an exhaustive tutorial for PRime, but one such document is currently in the works, and will be minted once the program itself is fully operational and ready for a proper release. Aside from the programming aspect, another crucial step in development is to locate a suitable Late Middle Chinese source of diaphonemic descriptions for each desired character within the massive Chinese lexicon–in digital form. So far, one of my friends was generous enough to provide me with such a source for an Early-Late Middle Chinese lexicon; many alterations will be required to convert the diaphonemic values into their appropriate LMC forms. I am also using a copy of the National Pronunciation Character Dictionary (校改國音字典) from 1921 as a primary reference–since it offers LMC values for each entry in the desired format (母呼聲韻)–but unfortunately my copy is a PDF file of scanned pages.

imron Posted June 13, 2014 at 12:30 AM Report Share Posted June 13, 2014 at 12:30 AM If you need an example of how to write an IME for Windows, Pinyinput (written by me in C++) is open source. I'm too busy with other projects at the moment to be able to collaborate on anything, but feel free to ask questions about the source code if you need.

Hofmann Posted June 13, 2014 at 07:17 AM Report Share Posted June 13, 2014 at 07:17 AM Awesome. I was going to say I'd like one for EMC, but then I saw this. 1 Quote Link to comment Share on other sites More sharing options...
Takeshi Posted June 13, 2014 at 05:42 PM Report Share Posted June 13, 2014 at 05:42 PM Yea, the most difficult thing to do is get a digital form of all of the phonemic descriptions in the format you want for the characters. Actually I think if you have that, then porting the input method to any other framework would be trivial. I can't really help you with the digital form description thing, but I wish you best of luck!

ParkeNYU Posted June 13, 2014 at 08:21 PM Author Report Share Posted June 13, 2014 at 08:21 PM @imron This is extremely helpful, thank you! Fortunately, I have a bit of experience in C'89 under my belt, though I had focused primarily on digital audio applications in the past. I will likely have a fair number of questions for you in the near future, so thank you for offering your assistance. --- @Hofmann Polyhedron's system seems to be the best when it comes to typing in EMC, though I am not too keen on a few aspects of his proprietary Pinyin scheme (namely assigning several of the voiced fricative initials to [zs] and its derivatives). --- It has recently come to my attention that a Japanese input method editor named 'PRIME' (predictive IME) has already been released on Ubuntu:https://apps.ubuntu.com/cat/applications/prime-dict/ I will continue to refer to my system as PRime (or as 析韻輸入法, its official Chinese name) until I figure out how to deal with this situation. Any suggestions are welcome, of course. Quote Link to comment Share on other sites More sharing options...

Hwong_DsiKiem Posted June 14, 2014 at 01:36 PM Report Share Posted June 14, 2014 at 01:36 PM My proposal for a Romanized PRime/Orthographic LMC (which I use among friends for fun) as a PRime teaching tool. The tones and initials have been discussed elsewhere. //iɛ// applies to <ia>, <iau>, <ian>, etc. <iua> is similarly //yɛ//. Screen-sized version here Edit actually "wi" seems to be 撮? I'll have to edit it to the proper column. Thinking about whether I should change it to iui... Likely not. Edit needed for "i" Quote Link to comment Share on other sites More sharing options...
Hwong_DsiKiem Posted June 15, 2014 at 12:55 AM Report Share Posted June 15, 2014 at 12:55 AM Btw, suppose you're catering to users of both simplified and traditional characters, I suggest having some sort of toggle button for full simplified or full traditional input, instead of the way the input I'm using does it: listing them as candidate characters, since you wanted something like canjie: ideally just one result with a combination of keystrokes. Unless you don't plan to cater to simplified characters here. Edit: unlike the caps lock switching between Chinese and English, it could be set with the keyboard layout or something, as in, not a key that toggles between trad and simp, but a setting. Also, since you have been saying stuff like users could use ZDic to check (or at least ZDic is one of your sources), and ZDic is more faifhful to EMC, perhaps you'll have to pay attention to the Man -uang + Canto -ong series. Weren't they -iâng in EMC and -âng in LMC? Edit: Actually, for a Romanized-PRime more suited to the input method, perhaps it'd be better to just have the four 呼 as --, i, w/u, iu and then name the shiep's by their 開 names. That way it'd save the possible inconsistencies -ei, -i and -wi, which would be reserved for ortho LMC. So, they become -iai, -i/-ii and -iui maybe, unless 撮 only marks the presence of both u and i, in which case -wi shouldn't be too much of a problem, although it'd mislead people into thinking it's from 合.

ParkeNYU Posted June 23, 2014 at 11:30 PM Author Report Share Posted June 23, 2014 at 11:30 PM I shall begin work on the official IME software (in ANSI C) shortly. In the meantime, here is a prototype that I've since withheld until developed to a satisfactory–albeit imperfect–state: (see original post) This program is far from perfect, but I feel that it provides an adequate starting point for introductory purposes. Updates are conducted on a continuing basis, and major ones shall be announced and shared in this thread. The latest versions of the PRime instruction manual and character dictionary have been appended to the first post of this thread. 1 Quote Link to comment Share on other sites More sharing options...
ParkeNYU Posted July 17, 2015 at 10:05 PM Author Report Share Posted July 17, 2015 at 10:05 PM I have finally crafted a standard Romanisation for PRime (析韻拼音). Please be advised that it is not pretty, but this is because the system is purely diaphonemic, and is not intended to represent any specific phonetic values. This Romanisation adopts all 26 letters of the English alphabet alongside the Arabic numerals 1 through 4 (for tones) to maximise compatibility (especially within programming environments). That being said, the letter assignments are not arbitrary; they are all based on broad phonetic resemblances and also represent an amalgamation of several established Chinese orthographies. Whilst the standard version of PRime defines each character with exactly four phonemic symbols, the Romanised version of PRime may define a character with as few as half the number of symbols, or with as many as twice the number of symbols.

ParkeNYU Posted April 9, 2016 at 12:51 AM Author Report Share Posted April 9, 2016 at 12:51 AM I thought it would be fun to make a 'symbol' version of PRime (with Katakana, Zhuyin, and standard characters) to use for annotation (析韻符號). Amazingly, I got it down to exactly 100 symbols (always three symbols per syllable: Initial + Final + Tone).

ParkeNYU Posted February 7, 2017 at 10:18 PM Author Report Share Posted February 7, 2017 at 10:18 PM I thought about providing the option to place the backspace/delete key in the upper-right corner rather than the lower-right corner of the mobile keyboard. This allows the grades (等第) of the finals (韻母) to line up correctly: 一三等 along the top row (外轉), 二三四等 along the middle row (外轉), and 一三等 along the bottom row (內轉). While most mobile inputs have the backspace/delete key in the lower-right corner, the mobile handwriting-recognition input method places it in the upper-right corner, so this move wouldn't be unprecedented (not to mention the fact that standard computer keyboards place it in the upper-right corner as well). What do y'all think? (please refer to original post) Quote Link to comment Share on other sites More sharing options...
ParkeNYU Posted October 19, 2017 at 09:24 PM Author Report Share Posted October 19, 2017 at 09:24 PM Only three taps (initial/final/tone) per character! Occupies the same area as normal keyboards with keys of the same size! All the initials and finals line up perfectly logically too for easy memory and location! Each of the 100 symbols are user-assignable as long as the replacements are Unicode-compatible! See the newly appended images and the 'symbols & pronunciation' file from my original post for more details! 1 Quote Link to comment Share on other sites More sharing options...
