Description

In Lucene 8.x, the Analysis.UIMA component has been replaced with Analysis.OpenNLP.

This is good news for us, because there are at least a couple OpenNLP options in .NET, a native port, and one using IKVM. Unfortunately, Lucene 8.x uses version 1.9.1 of OpenNLP, for which there is no equivalent so compatibility must be checked. Perhaps the best option would be to upgrade the first one (pull request) so we have native C# support, although the fastest option would certainly to use the IKVM version (which has no .NET Standard support).

https://www.nuget.org/packages/OpenNLP.NET/

This could make a great learning experience for how to port Java code to .NET, since the OpenNLP package is quite small in size.
