Anyone performed or knows some resources describing the main differneces between wit.ai, api.ai, and LUIS ? Any papers, datasets, or articles would be appreciated. Thank you
We cannot differentiate all the four on a single factor. The only different thing from all these 4 is the IBM Watson. IBM Watson is like a package which has a set of APIs and products like Virtual Agent, Explorer, Analytics and Knowledge Studio. Watson is also offered as a service (SaaS). Watson has a great impact in Digital Transformation of any business on a large scale.
Whereas all other three (API.ai, Luis.ai, Wit.ai) deal with tools for building Virtual Bots, Natural Language Processing, Adding Language Understanding to Applications using their APIs.
So, All these 3 offer services which are a part of IBM Watson. But the three services may have different set of features when compared to the IBM Watson. However, That fundamental difference may be found in a developer’s perspective who worked with all of these 4 platforms.
