I have released some NLP (natural language processing) tools with a LGPL license
BTW, I consider the LGPL to be "business friendly". You are allowed to mix my LGPL software with your own commercial products without open sourcing your products. You may also mix my LGPL software with open source with projects with Apache, BSD, MIT, or Mozilla style licenses. If you have any questions, ask me. If the LGPL license prevents you from using this material, please let me know about it.
