Objectives

The Web has developed into a global information space consisting not just of linked documents, but also of linked data. In 2010, we have seen significant growth in the size of the Web of Data, as well as in the number of communities contributing to its creation. In addition, there is intensive work on applications that consume Linked Data from the Web.

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. We also expect to see a number of submissions related to current areas of high Linked Data activity, such as government transparency, life sciences and the media industry. 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, we expect the event to further shape the ongoing Linked Data research agenda.

Important Dates

• Submission deadline: 8th February, 2011, 23:59 CET
• Notification of acceptance: 25th February, 2011
• Camera-ready versions of accepted papers: 10th March, 2011
• Workshop date: 29th March, 2011

Topics of Interest

Topics of interest for the workshop include, but are not limited to, the following:

Foundations of Linked Data

• Web architecture and dataspace theory
• dataset dynamics and synchronisation

Submissions

We seek three kinds of submissions:

1. Full technical papers: up to 10 pages in ACM format
2. Short technical and position papers: up to 5 pages in ACM format
3. Demo descriptions: up to 2 pages in ACM format

Submissions must be formatted using the WWW2011 templates. Please note that the author list does not need to be anonymized, as we do not operate a double-blind review process.

Submissions will be peer reviewed by at least three independent reviewers. Accepted papers will be presented at the workshop and included in the workshop proceedings.
