20.500.12556/RUP-22481 Type-based computation of knowledge graph statistics We propose a formal model of a knowledge graph (abbr. KG) that classifies the ground triples into sets that correspond to the triple types. The triple types are partially ordered by the sub-type relation. Consequently, the sets of ground triples that are the interpretations of triple types are partially ordered by the subsumption relation. The types of triple patterns restrict the sets of ground triples, which need to be addressed in the evaluation of triple patterns, to the interpretation of the types of triple patterns. Therefore, a schema graph of a KG should include all triple types that are likely to be determined as the types of triple patterns. The stored schema graph consists of the selected triple types that are stored in a KG and the complete schema graph includes all valid triple types of KG. We propose choosing the schema graph, which consists of the triple types from a strip around the stored schema graph, i.e., the triple types from the stored schema graph and some adjacent levels of triple types with respect to the sub-type relation. Given a selected schema graph, the statistics are updated for each ground triple t from a KG. First, we determine the set of triple types stt from the schema graph that are affected by adding a triple t to an RDF store. Finally, the statistics of triple types from the set stt are updated. knowledge graphs RDF stores graph database systems grafi znanja RDF zbirke podatkov grafovske podatkovne baze true false false Angleški jezik Slovenski jezik Članek v reviji 2026-01-16 09:58:28 2026-01-16 09:58:30 2026-01-17 03:05:30 0000-00-00 00:00:00 2025 0 0 str. 787-815 iss. 5 Vol. 93 Oct. 2025 0000-00-00 Zaloznikova NiDoloceno NiDoloceno 0000-00-00 0000-00-00 2025-01-17 004.65 1012-2443 10.1007/s10472-024-09965-3 223651843 RAZ_Savnik_Iztok_2025.pdf RAZ_Savnik_Iztok_2025.pdf 1 E3A36A91418B795906097D84E331D88A d89285a17d0d2b5af13794d53bf77da92bd19aa05af2707ef7942f456c250453 b0ca504e-f2b9-11f0-8639-005056ac49c0 https://repozitorij.upr.si/Dokument.php?lang=slv&id=32696 https://link.springer.com/article/10.1007/s10472-024-09965-3 1 8cc608b0-f2b9-11f0-8639-005056ac49c0 https://repozitorij.upr.si/Dokument.php?lang=slv&id=32695 Fakulteta za matematiko, naravoslovje in informacijske tehnologije 0 0 0
