Microsoft's latest version of its search API (our Live Search API Profile), which was released last November as a public beta, seems to be gaining quite a bit of momentum. According to a recent post on the Live Search Blog, the API is serving more than 3 billion queries per month, more than 5,000 applications to use the API, and queries from third party sites account for 80% of the API's query volume.
IBM continues to push the boundaries of human-machine interaction with its Watson, machine-learning platform. A new set up APIs allow third party software and hardware to leverage the platform. Tone Analyzer, Emotion Analysis, Visual Recognition, and Expressive TTS arrive as the new Watson APIs.
