My name is Ting Wang. I'm master student researcher of WCU Webometrics Institute, Yeungnam University South Korea.
I used NodeXL to tested Korean twitter search.
Our member and I detected that NodeXL only search the twitter English version (http://twitter.com/).
But in the twitter Korean version (http://twitterkr.com/) has more data for our research.
We research the politiciant's name-박근혜
You can see the difference search result of two version.
Best wishes~~ ^^*
NodeXL gets its Twitter data from a Web service. which is documented here:
I have been unable to find a Korean version of this Web service. If there is no such service, it is not possible for NodeXL to use Korean data.
