Watson is not "built on" Hadoop. From http://www.aaai.org/ojs/index.php/aimagazine/article/view/23...: To preprocess the corpus and create fast run-time indices we used Hadoop. UIMA annotators were easily deployed as mappers in the Hadoop map-reduce framework. Hadoop distributes the content over the cluster to afford high CPU utilization and provides convenient tools for deploying, managing, and monitoring the corpus analysis process. The online parts of Watson use UIMA: http://uima.apache.org/ |
