Snapquery EKAW 2024 paper

Key Points

1. Query rot versus link rot
2. Transparency vs. complexity of SPARQL queries
3. Use cases for named queries
4. Ambiguity of names
5. Persistent identifiers
   1. Query hashes and short_urls
6. How to deal with aspects that do not (usually) influence the execution of a SPARQL query, like whitespace, comments, capitalization and variable names?
7. Parameterized queries

   3. Scholia Jinja templates
8. technical debt and accidential complexity
9. Wikidata example queries
10. Scholia and Wikidata graph split
11. Other knowledge graphs, e.g., DBLP, OpenStreetMap
12. Perhaps also some NFDI examples or some custom knowledge graphs like FAIRJupyter
13. An Ngo Lam's ESWC 2023 paper as a pointer to the style of comparison
14. Quality criteria https://github.com/WolfgangFahl/snapquery/issues/26
15. List of standard refactoring activities and the support by this approach
16. SPARQL standard changes
17. Getting your own copy of Wikidata; the infrastructure effort needs to be mentioned
18. W3C test set - why did we not use that as an example
19. Useability evaluation https://www.nngroup.com/articles/why-you-only-need-to-test-with-5-users/
20. https://github.com/ad-freiburg/qlever/wiki/QLever-performance-evaluation-and-comparison-to-other-SPARQL-engines
21. Natural Language input
    1. Automatic syntax repairs
    2. automatic conversion of SQL input, SPARQL output.
22. A closed issue should have at least one example that runs
23. Hypothesis by Stefan Decker: Query rot is more prominent in KG environments than with relational databases.
