Today we announce the closure of our Term Extraction service on YDN, which will happen on March 31, 2012. So, you have plenty time to make changes to your applications using this service.
Term Extraction has been a part of YDN since 2006 and we are glad so many developers have found it useful over that time. As we've noted on the Term Extraction product page the closure will take place over two steps.
First, we will close access to the API in favor of access through YQL. We encourage all existing users of Term Extraction to migrate to YQL requests. If you are already using the Term Extraction API via YQL, you don't need to do anything.
We will subsequently retire Term Extraction in favor of a more advanced API, also accessed through YQL, Content Analysis API. Once you have migrated your calls to YQL, those same calls will work with Content Analysis. Content Analysis includes many features beyond Term Extraction and we hope you'll try it out today.
