USEWOD 2014: Building a Web Observatory for research on LOD usage


The USEWOD workshop series has created and maintained a forum for researchers to investigate the synergy between the Web of Data and Web usage mining. This involves the analysis of semantic data usage but also the exploitation of Semantic Web technologies to advance usage mining approaches in general. Among other things, USEWOD hosts what has become the reference data set for research on query logs of Linked Data endpoints.

This 4th edition of USEWOD will focus on this as a special theme: building a USEWOD Web Observatory to track the distribution of research based on the USEWOD data set. Web Observatories study a global network of heterogeneous data repositories, each observing and analysing the activity on the Web across a range of topics. Of course, the USEWOD data set has been extended again and a data challenge offered.

We invite submissions on this theme (and other topics pertinent to USEWOD), and in addition to paper presentations, the workshop will host a live crowdsourcing activity to collect the provenance metadata that finally brings together the root data set and as many publications that refer to it as possible. A keynote presentation will complement the contributed presentations and the crowdsourcing activity.
