The LDOW2011 workshop in Hyderabad follows the LDOW2008 workshop in Beijing, the LDOW2009 workshop in Madrid, and the LDOW2010 workshop in Raleigh. As with the previous workshops, LDOW2011 is open to covering all topics related to Linked Data publication and consumption, including principled research in the areas of user interfaces for the Web of Data as well as on issues of quality, trust and provenance in Linked Data. The goal of this workshop is to provide a forum for exposing high quality, novel research and applications in these (and related) areas. In addition, by bringing together researchers in this field, it is expected the event to further shape the ongoing Linked Data research agenda.
