SPARQLing Database Queries from Intermediate Question Decompositions [article]

Our pipeline consists of two parts: a neural semantic parser that converts natural language questions into the intermediate representations and a non-trainable transpiler to the SPARQL query language (  ...  We observe that the execution accuracy of queries constructed by our model on the challenging Spider dataset is comparable with the state-of-the-art text-to-SQL methods trained with annotated SQL queries  ...  Acknowledgements This research was supported in part through computational resources of HPC facilities at HSE University (Kostenetskiy et al., 2021).  ...

Querying semantic web data with SPARQL

Marcelo Arenas, Jorge Pérez

Thus, one usually obtains partial answers when querying RDF with SPARQL, and the possibility of adding optional information if present is a crucial feature of SPARQL.  ...  Some of the distinctive features of RDF have made the study and implementation of SPARQL challenging.  ...  This paper is a compendium of the material to be presented in a tutorial about RDF and SPARQL, targeted to database researchers that are new to Semantic Web data management.  ...

Towards Reconciling SPARQL and Certain Answers

However, the semantics of query answering under SPARQL entailment regimes is defined in a more naive and much less expressive way than the certain answer semantics usually adopted in DLs.  ...  SPARQL entailment regimes are strongly influenced by the big body of works on ontology-based query answering, notably in the area of Description Logics (DLs).  ...  Acknowledgements This work was supported by the Vienna Science and Technology Fund (WWTF), project ICT12-15 and by the Austrian Science Fund (FWF): P25207-N23 and P25518-N23.  ...

Our tutorial introduces the RDF ontological schema language for enhancing the RDF graphs' semantics, formalizes the query answering problem relying on reasoning, and provides a principled classification  ...  A great deal of effort has been invested, especially in the database community, into algorithms and tools for efficient RDF query evaluation.  ...  In the tutorial, we classify existing algorithms from the viewpoint of both the expressive power of the RDF fragment and of the query language.  ...
