    Dataset information                                                            
    Slashdot is a technology-related news website know for its specific user       
    community. The website features user-submitted and editor-evaluated current    
    primarily technology oriented news. In 2002 Slashdot introduced the Slashdot   
    Zoo feature which allows users to tag each other as friends or foes. The       
    network cotains friend/foe links between the users of Slashdot. The network was
    obtained in February 2009.
