I want to make a NL query generator, but I don't know where to start. I do have some knowledge of CFG (with letters) and Makkov chain, but am not so sure where to begin with. Can you share me some guidance on where to start. I am trying to build this own so I need background knowledge.

I already have a template NL query, but I know that it can only take me so far. Thus I kinda want to include probablity (Markov Chain and N grams, might come here) but I don't want to rely on prob along. It should be something hybrid, which am confused with.

Thanks
