Which painter was the most impactful? Is tapestry more important than mosaic? How influential a genre is portrait? Rankingdom is an analysis tool for Wikidata entities that helps answer such questions. It provides statistical indicators comparing any entity to similar entities. For frugality reasons, indicators are calculated on demand and cached. This requires the execution of many complex SPARQL queries, which are limited in complexity and frequency by Wikidata’s fair use policy. Thus, we introduce a decentralized architecture with a client-side parallelization engine (SParaQL) that decomposes and merges queries. Our approach is validated by the deployment of Rankingdom and a user study. Application: https://www.rankingdom.org Demo video: https://youtu.be/Swpj2PCU6K0

摘要

Which painter was the most impactful? Is tapestry more important than mosaic? How influential a genre is portrait? Rankingdom is an analysis tool for Wikidata entities that helps answer such questions. It provides statistical indicators comparing any entity to similar entities. For frugality reasons, indicators are calculated on demand and cached. This requires the execution of many complex SPARQL queries, which are limited in complexity and frequency by Wikidata’s fair use policy. Thus, we introduce a decentralized architecture with a client-side parallelization engine (SParaQL) that decomposes and merges queries. Our approach is validated by the deployment of Rankingdom and a user study. Application: https://www.rankingdom.org Demo video: https://youtu.be/Swpj2PCU6K0
