An unofficial nuget binary package of UniDic-CWJ

Alissa.UniDic-CWJ.binary is a nuget package to provide binary dictionary of "UniDic-CWJ, the analysis dictionary for the morphological analizer MeCab" (解析用現代書き言葉 UniDic).

It is Alissa Sabre's unofficial packaging of UniDic analysis dictionary to help setting up the dictionary for use in your app.

Due to its large size, the files are split into four nuget packages. See below for how to use it.

UniDic is a cover-all name for

1. design principles of an electronic dictionary for Japanese language based on a set of uniform lexical units (called SUW, Short Unit Word, 短単位) and hierarchical definition of word indexes both defined by National Institute for Japanese Language and Linguistics (国立国語研究所);
2. UniDic database, a relational database that implements the principles; and
3. the analysis dictionaries for the morphological analizer MeCab, an analysis dictionary whose entries consist of SUWs exported from the UniDic database for use with MeCab.

You can learn more on UniDic on its official website: https://unidic.ninjal.ac.jp

For the moment, there are several types of UniDic analysis dictionaries published, including UniDic-CWJ (現代書き言葉 UniDic) and UniDic-CSJ (現代話し言葉 UniDic). Alissa.UniDic-CWJ.binary is the binary package for the analysis dictionary UniDic-CWJ (現代書き言葉 UniDic).

MeCab is a part-of-speech and morphological analyzer primarily for Japanese language, originally developed by Taku Kudo (工藤拓) in joint project between Graduate School of Informatics, Kyoto University (京都大学大学院情報学研究科) and NTT Communication Science Laboratories (日本電信電話株式会社コミュニケーション科学基礎研究所) in mid '00s. It is now widely used as a basis of academic researches of Japanese language and/or various Japanese language processing systems.

The original version of MeCab was written in C++.

Use your nuget/MSBuild-compatible development environment to download and install Alissa.UniDic-CWJ.binary nuget package into your app project. During the build process of your app (using MSBuild or a compatible build tool), a subfolder of name UniDic-CWJ is created in your $(OutDir) (the folder that you will get your .exe or .dll in), and the binary files of analysis dictionary are copied into it automatically.

Due to the large size of the dictionary files and the package size limitation that nuget.org insists, the dictionary files are split into four nuget packages: the main package Alissa.UniDic-CWJ.binary and three supplementary packages. You always need the four packages to use UniDic-CWJ analysis dictionary. The main package depends on the three supplementary packages, so you only need to specify the main package in your development environment; supplementary packages should be downloaded and installed automatically.

Note that this nuget package (or a set of four packages) only contains the binary dictionary files. You need to have MeCab (or compatible software) separately. (I'm primarily using NMeCab, a .NET port of MeCab analysis library, for my purposes recently.)

It contains additional files other than UniDic that I used to produce the set of nuget packages.
