These slides represent the third of a five-part tutorial presentation given at the 22nd International World Wide Web Conference (WWW 2013). For the execution of Linked Data queries, it is necessary to retrieve data by looking up URIs. There exist three classes of approaches for selecting the URIs that a query execution system looks up during the execution of a query: 1) index-based approaches, 2) live exploration, and 3) hybrid approaches. This part of the tutorial introduces each of these types and discuss their respective characteristics, advantages and limitations.
