C#でかな漢字変換を実現するライブラリです。以下の特徴を備えています。
- Mozc辞書ベース
- AhoCorasickDoubleArrayTrieを使用した高速な検索を採用
- NBest変換取得のみのシンプルな機能
このライブラリは開発中であり、別のリポジトリでさらに開発を進めていく予定です。そのため現在はパッケージでの配布予定はありません。
使用には.NET SDKが必要です。
-
リポジトリのクローン
git clone https://github.com/tkxp200/DotNetKKC_prototype.git -
新しいConsoleプロジェクトを作成
dotnet new console -o "DotNetKKCTest" cd DotNetKKCTest -
DotNetKKCを依存関係に追加
dotnet add reference ../DotNetKKC_prototype/DotNetKKC.csproj -
辞書データの配置
dicディレクトリを作成しGoogle Mozcのsrc/data/dictionary_oss配下にある
dictionary*.txtおよびconnection_single_column.txtを配置します。検証はしていませんがmozc-ut辞書も使用できると思います。
mkdir dicdicディレクトリ配下に次のファイルがあればOKです。
+---dic | connection_single_column.txt | dictionary00.txt | dictionary01.txt | dictionary02.txt | dictionary03.txt | dictionary04.txt | dictionary05.txt | dictionary06.txt | dictionary07.txt | dictionary08.txt | dictionary09.txt -
DoubleArrayの生成
Program.csを次のように編集し変換に必要なDoubleArrayファイルをdicフォルダ配下にあるtxtファイルを用いて生成します。-
Program.cs
using DotNetKKC; string dictionaryPath = @"./dic"; string doubleArrayPath = @"./dic/dictionary.doublearray"; var generator = new DoubleArrayGenerator(dictionaryPath, doubleArrayPath); generator.Build();
-
実行
dotnet build dotnet run
実行には30秒～2分ほどかかります。
dicディレクトリ配下に
dictionary.doublearrayが生成されていればOKです。$ ls dic connection_single_column.txt dictionary04.txt dictionary.doublearray dictionary05.txt dictionary00.txt dictionary06.txt dictionary01.txt dictionary07.txt dictionary02.txt dictionary08.txt dictionary03.txt dictionary09.txt

かな漢字変換
GetConversion関数を呼び出すと変換後の文字列とコストの辞書が返ってきます。
クラスのインスタンス化時に辞書を読みだすため3~5秒ほど時間がかかります。-
Program.cs
using DotNetKKC; string doubleArrayPath = @"./dic/dictionary.doublearray"; var conversion = new Conversion(doubleArrayPath); Dictionary<string, double> result = conversion.GetConversion("ここではきものをぬぐ", 20); int i = 0; foreach (KeyValuePair<string, double> item in result) { Console.WriteLine($"{i + 1:00}Best Conversion: {item.Value:000000}, {item.Key}"); i++; }
GetConversion()の第二引数で取得する変換候補の数nを設定できます。省略するとn=10の変換候補が返ってきます。 -
実行
$ dotnet run Convert: ここではきものをぬぐ 01Best Conversion: 017550, ここでは着物を脱ぐ 02Best Conversion: 018373, ここで履物を脱ぐ 03Best Conversion: 018502, ここではきものを脱ぐ 04Best Conversion: 019001, ここでは着物をぬぐ 05Best Conversion: 019017, ここで履き物を脱ぐ 06Best Conversion: 019824, ここで履物をぬぐ 07Best Conversion: 019929, 個々では着物を脱ぐ 08Best Conversion: 019953, ここではきものをぬぐ 09Best Conversion: 020069, ここで破棄者を脱ぐ 10Best Conversion: 020129, ここではキモノを脱ぐ 11Best Conversion: 020443, ここで履きものを脱ぐ 12Best Conversion: 020468, ここで履き物をぬぐ 13Best Conversion: 020552, ここではき物を脱ぐ 14Best Conversion: 020747, 此処では着物を脱ぐ 15Best Conversion: 020752, 個々で履物を脱ぐ 16Best Conversion: 020881, 個々ではきものを脱ぐ 17Best Conversion: 021021, ここでは気物を脱ぐ 18Best Conversion: 021025, ここで吐きものを脱ぐ 19Best Conversion: 021065, ココでは着物を脱ぐ 20Best Conversion: 021129, ここで破棄物を脱ぐ
