YASGUI: Feeling the Pulse of Linked Data.

Existing studies of Linked Data focus on the availability of data rather than its use in practice. The number of query logs available is very much restricted to a small number of datasets. This paper proposes to track Linked Data usage at the client side. We use YASGUI, a feature rich web-based query editor, as a measuring device for interactions with the Linked Data Cloud. It enables us to determine what part of the Linked Data Cloud is actually used, what part is open or closed, the efficiency and complexity of queries, and how these results relate to commonly used dataset statistics.
