Is there an open-source NLP network?


I`m in the early stages of self-research on General-AI. I have created a basic model on how general-AI should work. NLP is one of the first requirements for a general-AI. I wanted to know if there is any open-source NLP network (pre-trained).

Neural-network requirements:
It should parse sentences and add meaning to them. (Understanding basic verbs)
Reserved. (Haven’t figured out yet xD)

I am looking forward to inter-linking multiple specialized neural-nets to work in tandem.

has anyone ever tried an NLP program based on objects? Or do all NLPs are based on objects?
