Term Frequency - Inverse Document Frequency (TF-IDF) #55
Description
It would be a nice addition for those using Accord.NET in text applications, specially now that more linear optimization algorithms are available.
Kory Becker has created a nice implementation (under a compatible license) which can be used as a basis for the implementation. The current code can be found here:

However, it seems the implementation needs a stemmer. In this case, the stemmer could be incorporated in the project by specifying a new ITextStemmer interface. Different stemmers could than be created using the Snowball project:

It would be cool to add a new text generator in Snowball for C#. It shouldn't be that difficult given that there are working Java generators available.
