There are many idols like to promote their event on Twitter. But those people who like appreciate idols`performance won`t know that without following them. So I got an idea.We can use LOD to collect data from Twitter, including when and where the event will be. Then we can show them in Map by icons.Users can get the information just by clicking the icon.
Besides, idol fans usually followed idols that thay are same type.So maybe user can find more interesting idol or groups.It also will benefit idols to be loved by more fans.
Then we can read the data and store it in a database.(I used picture to take place of words. In fact,It will be words that be stored in database.Using machine learning or something to get the data from picture.)
