twXray: helps to know which issues speaks any Twitter user

twXray is a new web application in beta that helps to know which issues any Twitter user speaks. It was created by researchers at the Knight Innovation Lab at Northwestern University.

You only have to enter the user name and the service will analyze some of the latest tweets of it and organized by topics such as technology, entertainment, sports, travel and more.

After assigning each tweet analyzed the relevant category, gives us a graph showing the percentage of tweets for each of these categories. It also shows some tweets from the category you select.

It’s not perfect because sometimes can confuse some tweet and assign a category mistake. But in general it offers good results that can serve us to determine which is the topic of conversation preferred of the user.
