Has anyone heard about a replacement for the Concept Expansion service? <p>I have been learning about the IBM Watson services and Bluemix over the last few months. I had previously looked at the Concept Expansion service but when I returned to the <a href="http://www.ibm.com/smarterplanet/us/en/ibmwatson/developercloud/concept-expansion.html" rel="nofollow noreferrer">page</a> where this service is described, I found the message from IBM that this service was being withdrawn: <a href="https://i.stack.imgur.com/7XOFe.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/7XOFe.png" alt="Announcement that the Concept Expansion Service is being withdrawn"></a> Has anyone seen or heard of an alternative or replacement being suggested or offered by IBM?</p>
