The API.AI .NET SDK by API.AI aims to simplify API integration features of natural language processing into new applications. Resources include a programming interface to make text and voice requests to the API.AI. Additional resources could be useful to add usages to a module, add field to a class, and initialize object with Keys. See how JSON.NET helped with parsing implementation at http://www.newtonsoft.com/json
Kairos, known for its cloud-based face recognition solution, has introduced an on-premise version of its API. An on-premise option allows users to better secure their use cases, and reduces latency between apps that consume the API, and the compute-heavy cloud where Kairos built its tech.
