MTL Toolbox

MTL Toolbox (https://learntaiwanese.org/MTLtoolbox/about.html) is software and data to help work with written Taiwanese using the Modern Taiwanese Language (MTL) writing system and other romanizations for Taiwanese.

Features

six Taiwanese dictionaries spanning from Japanese era to present day
full-text search engine accepts written Taiwanese as well as English, and Harnji
audio from government-compiled dictionary: DFT
basic text segmentation (including "unjoining" into syllables) and "bag-of-syllables" search
Seven Tones soundboard: table of all MLT finals with examples

How to search

We describe how to use "Taiwanese–English dictionaries: segmenter & full-text search". This interface is mainly for Taiwanese words written in MLT or MTL, which we refer to as "M-style" written Taiwanese. After entering M-input, press "Zhøe" to run the segmenter and search.

Typical usage

Input: Taiwanese word (typically disyllable: two syllables joined by tone sandhi)
- Example: køefcie (copy and paste into this link [1])
Press return or tap "Zhøe" (means "search")
- your input is "unjoined" (original syllables found by database lookup)
  - in this example, the original syllables are: køea and cie
- search is done using original syllables (unordered collection of syllables, or "bag-of-syllables")
- confirm the results are the same as for input: (except for Htb which is not unjoined)

Try more examples:
- chviafmng
- tøsia
- Taioaan

Monosyllable

for a monosyllable, exact matches are displayed by default, for example (PTC):
- goar
- lie
- ee

if the syllable is a DFT monosyllable, a navigation bar displays adjacent DFT monosyllables in alphabetical order
due to high number of matches, "monosyllable mode" returns monosyllable search results. To see all matching results, click "Khahzøe"

Other fields

The "en" button is used to direct the search to the English field (en). Harnji (hj) can also be input, although we do not attempt Chinese text segmentation.

Data

Local copies of:

HTB: Hiexntai-buun Dictionary
DFT: Dictionary of Frequently-Used Taiwanese Taigi (in TL. We added MTL annotations and annotated over 5800 definitions in English for monosyllables)
MK: Maryknoll Taiwanese-English Dictionary (in POJ. We added MTL annotations)
EDUTECH: Liim Keahioong (2001-2003) EDUTECH: Taiwanese-English Dictionary Searched with Concise Atonal Spelling (in MLT with unified spellings (øe))
Embree, Bernard L. M. (1973). A Dictionary of Southern Min: based on current usage in Taiwan and checked against the earlier works of Carstairs Douglas, Thomas Barclay, and Ernest Tipson. Hong Kong: Hong Kong Language Institute. (in POJ. We added MLT annotations)
Lim08: Tai-Nichi Daijiten translated into Taiwanese. (original 1931 & 1932, in Taiwanese kana. Data in POJ. We added MLT annotations)

We also support searching other websites with conversion to POJ/TL:

Lim (2019): Tai-Nichi Daijiten
Taibuun/Hoabuun Svoarterng Sutiern

Technical notes

SQLite: FTS4 for full-text search
Token prefix queries: use the asterisk ('*') at the end. Similar to wildcard character in operating systems (normal wildcard search not currently supported by FTS)
- Example: Taioa*, 臺*
Specify a column-name followed by a colon (':')
- Example: hj:頭* (returns entries where Taiwanese written with Harnji begins with character for thaau)
Add carat ^ before token to require token to be very first token in its column
- Example: ^thaau
