Stanford.NLP.NET


Stanford NLP Software for .NET

The Stanford NLP Group makes parts of Natural Language Processing software available to everyone. These are statistical NLP toolkits for various major computational linguistics problems. They can be incorporated into applications with human language technology needs.

Getting started

  • Choose the package that is the most suitable for your task. If your task is complex and you need a deep analysis - select Stanford CoreNLP.
  • Install selected NuGet package.
  • Download original ZIP archive for selected package from The Stanford NLP Group site. (Direct links are mentioned on the packages pages)
  • Unzip *.jar file with models if such one exists.
  • You are ready to start, please look at examples.

Note: Do not try to reference several NuGet packages from your solution. They are incompatible with each other. If you need more than one - you should reference Stanford CoreNLP package. All features are packed inside.

If you want to speed up the conversion of some new Stanford software or you want to see new .NET samples for already existing distributions - please mention this in issues. It can really help you get it sooner.

Supported software distributions

All these software distributions are open source, licensed under the GNU General Public License (v2 or later). Note that this is the full GPL, which allows many free uses, but does not allow its incorporation into any type of distributed proprietary software, even in part or in translation. Commercial licensing is also available; please contact The Stanford Natural Language Processing Group if you are interested.
