“…Among the types of preference-based queries that have been most extensively studied are skyline queries (Borzsonyi et al, 2001), which constitute one of the most practical and predominant types of preference-based queries (Gulzar et al, 2019). They return the most interesting objects according to the user"s criteria based on the Pareto dominance operator (Abidi et al, 2017). Skyline queries are typically used in multi-criteria decisionmaking applications to find answers that are of interest to a user .…”

The growth of RDF (Resource Description Framework) datasets and the expansion of their use in conjunction with the definition of SPARQL, a declarative query language, have made RDF data management an active area of research and development. In this regard,mechanisms have been proposed to help users find their desired answers in less time, including ranking methods and preference-based queries. Skyline queries constitute one of the most practical and predominant types of preference-based queries. The aim ofthis work was to provide a guide to specifying SPARQL skyline queries using syntax proposed in state-of-the-art works, and SPARQL versions 1.0 and 1.1. The results show the possibility of rewriting skyline queries in SPARQL to express preferences. We planto develop a tool to translate SPARQL skyline queries applying the different grammars proposed, into SPARQL 1.0 and 1.1 with the aim of providing an automatic mechanism of translation.
