  • New Content Analysis API

    Today we're pleased to announce the availability of our new Content Analysis service through YQL. Content Analysis replaces Yahoo!’s popular Term Extraction service and now provides advanced content analysis on either text or a URL, leverages Yahoo!’s state of the art MLR technology to extract key terms from the content, and, more importantly, to rank them based on their overall importance to the content.

It ranks those detected entities/concepts by their overall relevance, resolves those if possible into Wikipedia pages, and annotates tags with relevant meta-data.

    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.

    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.
