Gensim for .Net

[Samuel Leeman-Munk]

Hi, I'm Sam.

I'm looking to use LSA in my C# project and I'm wondering what work has been done to make Gensim usable in .net?

I've tried pyrolite, but the network connection part of it takes five seconds for a task (converting of a given document into a conceptual feature vector) that should take more around a millisecond, making it unusable.

Has anyone had any more luck that could help point me in a right direction? Right now I'm considering trying IronPython to make the whole Gensim Library into a .Net IronPython library, but I'm not exactly sure how feasible that really is.

Let me know!

Hello Sam!

I never tried, but using gensim itself should be straightforward -- it's pure Python.

Trouble may come from the dependent libraries: NumPy and especially SciPy (+ BLAS linking for best performance). If you get these two running in .net, you're set :)

Say I find NumPy and SciPy IronPython libraries, then I go to the Gensim python source and just copy/paste it all into a new C# project with IronPython.

There's nothing else to Gensim that I might be missing?

And seeing as you are the illustrious Řehůřek himself, to what extent could I keep the greater project I use my work here in proprietary if I agreed to release "Gensim.Net" itself as open source?

To be clear:
"Gensim.Net" <- I don't mind releasing code

My project which uses Gensim.Net <- My employers prohibit the release of source

Thanks so much!

Sam

depends what "Gensim.Net" is?

Gensim is licensed under LPGL:

http://en.wikipedia.org/wiki/GNU_Lesser_General_Public_License

People use gensim in proprietary solutions, that's no problem.

If you make worthwhile modifications to gensim itself, it's best to submit them back so I can merge them into the "official" repository on github.

HTH,

Let's say "Gensim.Net" is a full or partial port of the Gensim Python code into C#. I would be all too happy to give it to the open source community once I've made it. If I then use this port in my proprietary project without further modification, does that meet the terms of the license? I'm having trouble with the license's legalese.

You mean recoding everything in C#? That is an interesting proposition :)

Much of gensim's API and features are tailored to Python, but if a C# port makes more sense, why not. I don't even see much point calling it "gensim" -- it will be your project, with maintenance and support done by you, because I couldn't really support a C# port.

my proprietary project without further modification, does that meet the terms of the license? I'm having trouble with the license's legalese.

The wiki link I posted above summarizes the LGPL license nicely I believe, without much legalese. Using gensim in proprietary projects is fine.

My overall position is: I care more about people contributing back and crediting gensim properly. I don't mind people monetizing their own projects that use gensim internally or whatever. For me, gensim is about generating leads to my ML & IR consulting business.

Best,

Radim

Hi Samuel

Have you succeeded in installing Gensim to IronPython? If so, please share.

Thanks,

Steph

[Samuel Leeman-Munk]

I will let you know if I do. For the moment I have determined that it is not important enough to my project to be worth spending the time.

I've loaded iPython 64 and SciPy/Numpy. Just having a spot of trouble with the gensim setup.

If anyone could help with that it would be great. Currently using ZeroMQ to communicate from .NET to Python worker tasks in Winsows Services. Would be preferable to be all .NET...

I'm interested in LSA in C#, yes, although my work in particular has moved away from it so I wouldn't have much free time to devote to the conversion.

Hi Sam

Are you still interested in LDA in C#?

Give me a ping.
