Efficient SPARQL Queries Generator for Question Answering Systems
IEEE Access, 2022 Much like traditional database querying, the question answering process in a Question Answering (QA) system involves converting a user’s question input into query grammar, querying the knowledge base through the query grammar, and finally returning the ...

Efficient SPARQL Autocompletion via SPARQL
, 2021 We show how to achieve fast autocompletion for SPARQL queries on very large knowledge bases. At any position in the body of a SPARQL query, the autocompletion suggests matching subjects, predicates, or objects. The suggestions are context-sensitive in the sense that they lead to a non-empty result and are ranked by their relevance to the part of the ...

LSQ 2.0: A linked dataset of SPARQL query logs
Semantic Web, 2022 We present the Linked SPARQL Queries (LSQ) dataset, which currently describes 43.95 million executions of 11.56 million unique SPARQL queries extracted from the logs of 27 different endpoints. The LSQ dataset provides RDF descriptions of each such query,

Modeling of colored Petri nets using semantic Web technologies
Известия высших учебных заведений. Поволжский регион:Технические науки, 2022 Background. In connection with the widespread use of the Semantic Web concept, the issues of using formal models in the design of parallel, distributed and multi-agent systems based on the Semantic Web are of interest.

An analytical study of large SPARQL query logs [PDF]
The VLDB journal, 2017 With the adoption of RDF as the data model for Linked Data and the Semantic Web, query specification from end users has become more and more common in SPARQL endpoints.

Semantics and canonicalisation of SPARQL 1.1
Semantic Web, 2022 We define a procedure for canonicalising SPARQL 1.1 queries. Specifically, given two input queries that return the same solutions modulo variable names over any RDF graph (which we call congruent queries), the canonicalisation procedure aims to rewrite ...

FAIR Jupyter: A Knowledge Graph Approach to Semantic Sharing and Granular Exploration of a Computational Notebook Reproducibility Dataset [PDF]
Transactions on Graph Data and KnowledgeThe way in which data are shared can affect their utility and reusability. Here, we demonstrate how data that we had previously shared in bulk can be mobilized further through a knowledge graph that allows for much more granular exploration and ...
