Ah, this brings back memories. I tried something like that about 12 years ago, with a homebrewn half-hardcoded, half-neural thing and a large set of Jules Verne books.

The giddy excitement of being on the verge of unlocking the power of language slowly turned into confusion and then decayed into disappointment as i slowly realized that the task was maybe a bucket of orders of magnitude harder than i thought. I think it produced some coherent phrases every now and then, but mostly it was a random words generator.

...I miss these amplified feelings of cluelessly diving into an impossible project...
