I'm looking for companies that offers Natural Language Generation technology. This is what I need to do: starting from structured data (time-series, records) about some past, current and forecasted phenomena of a specific field, I'd like to see whether some narrative (500-1000 words), in English, can be automatically generated but in a way that does look linguistically rich and semantically grounded. I already tested out some rule-based systems, but they lack the afore mentioned characteristics.

Do you guys know of such companies? I would skip research institutions providing pieces of software: I'm more looking into already built products.

Thanks a lot!
