The Open mic session starts on Friday 24th November 2023 at 10:30 at this link. The speaker is Miroslav Blaško who opens the topic of Debugging SPARQL Queries using algebra.

The abstract

Semantics of SPARQL queries can be expressed by SPARQL Algebra. Tools like SPARQL Validator provides translation of SPARQL queries into its algebraic representation. The talk will explore a few perplexing examples of SPARQL queries, illustrating how the translation can be used to understand/debug such queries.
