Ask HN: What programming language is Watson written in?
I am very curious about what programming language was used to write the Watson software that IBM used to play Jeopardy. There is a screen of code at 1:49 in this, http://www-943.ibm.com/innovation/us/watson/what-is-watson/a-system-designed-for-answers.html video, but I couldn't make out the language and it could just be a filler. Has anybody seen anywhere it was mentioned?

- Skywing 16y agoThe screen where the guy is coding on his laptop looks like Java, to me.

- staunch 16y agoI can read "Java application" and a "/home/wind(?)/workspace/watson/" path, so it's probably real code and it's written in Java.
- rst 16y agoI'm not sure it's all Java, but there's a lot of Java in there; looking at the systems team pages[1], there's mention of two Apache Java projects, UIMA and Hadoop... [1] http://www.research.ibm.com/deepqa/systems_team.shtml http://www.research.ibm.com/deepqa/systems_team.shtml

- solipsist 16y agoFunny, that particular code from the same video inspired this own post of mine: http://news.ycombinator.com/item?id=2219801 http://news.ycombinator.com/item?id=2219801
- landon 16y agoWatson was written in mostly Java but also significant chunks of code are written C++ and Prolog, all components are deployed and integrated using UIMA. http://blog.reddit.com/2011/02/ibm-watson-research-team-answers-your.html http://blog.reddit.com/2011/02/ibm-watson-research-team-answ...
