After the great success of the first Leipziger Semantic Web Tag (LSWT) in 2009 AKSW is organizing another installment of this event on 6th May. In addition to demonstrating the benefits of semantic technologies to enterprises, this year’s LSWT focuses on Open Data in science and E-government. A particular highlight will be the festive announcement of the German chapter of the Open Knowledge Foundation. More information on the LSWT can be found (in German) at: http://aksw.org/Events/2010/LeipzigerSemanticWebDay.
