Abstract

A number of studies have analyzed SPARQL log data to draw conclusions about how SPARQL is being used. To complement this work, a survey of SPARQL users has been undertaken. Whilst confirming some of the conclusions of the previous studies, the current work is able to provide additional insight into how users create SPARQL queries, the difficulties they encounter, and the features they would like to see included in the language. Based on this insight, a number of recommendations are presented to the community. These relate to predicting and avoiding computationally expensive queries; extensions to the language; and extending the search paradigm.

At the p < 0.5 level; note that, because of the ties, the p-values are not exact. Statistical analysis was undertaken using the R statistical package (R Core Team 2014).

This percentage was calculated out of a total of 15; one of the developers did not respond to the question about query types.

I.e., the four possibilities generated by beginning the path with either a variable or a constant (URI or literal) and terminating with a variable or constant: V*C, V*V, C*V, and C*C.

I.e. all responses were either ‘frequently’ or ‘occasionally’.
