I have found no good cloud “middleware” for artificial intelligence applications. My ideal would be something visual like Yahoo! Pipes. The main point is how to integrate the proliferating APIs in the cloud, in other words from the browser, and ideally language independent.
There are plug and play SaaS and iPaaS solutions for business processes, but are not adequate for most natural language applications. I’m thinking about something IFTTT simple. In particular, see my 2012 videos from Chatbots 3.2 – Philadelphia.
