In ongoing efforts to investigate the effectiveness of the ScaSpa type system and SPARQL query validation approaches, we take a look at query logs. In particular we aim to apply the ScaSpa approach to queries that were executed against the public DBpedia and Wikidata SPARQL endpoints. This talk presents some of the challenges related to, and shortcomings of, available data sets for this purpose. In addition to intermediate results, we investigate routes to improve the applicability of our approaches, ranging from the introduction of disjointness to leveraging mappings between DBpedia and Wikidata.
