Snapquery EKAW 2024 paper
Key Points
- Query rot versus link rot
- Transparency vs. complexity of SPARQL queries
- Use cases for named queries
- Ambiguity of names
- Persistent identifiers
- Query hashes and short_urls
- How to deal with aspects that do not (usually) influence the execution of a SPARQL query, like whitespace, comments, capitalization and variable names?
- Parameterized queries
- technical debt and accidential complexity
- Wikidata example queries
- Scholia and Wikidata graph split
- Other knowledge graphs, e.g., DBLP, OpenStreetMap
- Perhaps also some NFDI examples or some custom knowledge graphs like FAIRJupyter
- An Ngo Lam's ESWC 2023 paper as a pointer to the style of comparison
- Quality criteria https://github.com/WolfgangFahl/snapquery/issues/26
- List of standard refactoring activities and the support by this approach
- SPARQL standard changes
- Getting your own copy of Wikidata; the infrastructure effort needs to be mentioned
- W3C test set - why did we not use that as an example
- Useability evaluation https://www.nngroup.com/articles/why-you-only-need-to-test-with-5-users/
- https://github.com/ad-freiburg/qlever/wiki/QLever-performance-evaluation-and-comparison-to-other-SPARQL-engines
- Automatic syntax repairs - automatic conversion of SQL input, SPARQL output.
- A closed issue should have at least one example that runs
- Hypothesis by Stefan Decker: Query rot is more prominent in KG environments than with relational databases.
