HFST.net

A C# implementation of HFST. The code is based on HFST for Java.

Installation

You can install the NuGet package in Visual Studio or use the command-line tools

dotnet add package MikaHamalainen.hfst

After installing the package, you can import it like this:

using hfst;

Usage

You can load a transducer like this

var transducerFile = "/path/to/transducer.hfstol";
var t = new HFST(transducerFile);

HFST can be initialized with a string path, FileStream or BinaryReader.

You can run the transducer like so:

var analyses = t.Lookup("koira+N+Sg+Ine");
foreach (var analysis in analyses)
{
    Console.WriteLine($"{input}\t{analysis}\t{analysis.Weight}");
}

Output:

koira+N+Sg+Ine	koirassa	0

You can get the analysis as a string by calling analysis.ToString()
