Build Status

Stanford.NLP for .NET

Stanford.NLP for .NET is a port of Stanford NLP distributions to .NET.

This project contains build scripts that recompile Stanford NLP .jar packages to .NET assemblies using IKVM.NET, tests that help to be sure that recompiled packages are workable and Stanford.NLP for .NET documentation site that hosts samples for all packages. All recompiled packages are available on NuGet.

Master package

  • NuGet Badge - Stanford.NLP.CoreNLP

Other packages

  • NuGet Badge - Stanford.NLP.NER
  • NuGet Badge - Stanford.NLP.Parser
  • NuGet Badge - Stanford.NLP.POSTagger
  • NuGet Badge - Stanford.NLP.Segmenter


Versioning model used for NuGet packages is aligned to versioning used by Stanford NLP Group. For example, if you get Stanford CoreNLP distribution from Stanford NLP site with version 3.3.1, then the NuGet version of this package has a version 3.3.1.x, where x is the greatest that is available on NuGet. Last number is used for internal versioning of .NET assemblies.
