• 54 abstract "In order to reduce the cost of publishing queryable Linked Data, Triple Pattern Fragments (TPF) were introduced as a~simple interface to RDF triples. It allows for SPARQL query execution at low server cost, by partially shifting the load from the server to the client. The previously proposed client algorithm uses more HTTP requests than strictly necessary, and only makes partial use of the available metadata. In this paper, we propose a new query execution algorithm for a client communicating with a TPF server. Instead of using a greedy solution, we maintain an overview of the entire query to find the steps that are optimal for solving a given query. We show multiple cases in which our implementation produces a solution containing far fewer server calls, while not significantly increasing the cost in other cases. This improves the efficiency of common SPARQL queries against TPF interfaces, augmenting their viability compared to the more powerful, but more costly, SPARQL interface.".
