Index Stemming to process text in C# or ruby

Question

Given this text:

"Friends are friendlier friendlies that are friendly and classify the friendly classification class. Flowery flowers flow through following the flower flows"

I need to apply stemming to the text to achieve the following outcome:

frequency("following")                = 1
frequency("flow")                     = 2
frequency("classification")           = 1
frequency("class")                    = 1
frequency("flower")                   = 3
frequency("friend")                   = 4
frequency("friendly")                 = 4
frequency("classes")                  = 1

As we interface with the FAST search engine. FAST indexes content to provide relevant search results to a query. One aspect of indexing is stemming and we need to use either C# or ruby to solve this.

Would appreciate anyone's views on the best approach

    public StemmingProcessorResults ProcessText(string text)
    {
            return new StemmingProcessorResults(
                    new []{
                        new StemmingProcessorResultItem("following", 1),
                        new StemmingProcessorResultItem("flow", 2),
                        new StemmingProcessorResultItem("classification", 1),
                        new StemmingProcessorResultItem("class", 1),
                        new StemmingProcessorResultItem("flower", 3),
                        new StemmingProcessorResultItem("friend", 4),
                        new StemmingProcessorResultItem("friendly", 4),
                        new StemmingProcessorResultItem("classes", 1)
                    }
                );
    }

There you go, that should be perfect for your copy-paste needs
