QuerioCity: Accessing the Information of a City (DEMO)

Other approaches in this domain have several limitations: content portals (e.g. twc open gov data portal, data.gov.uk, IOGDC (Ding et al. 2011)) lack sufficient capabilities to explore, navigate and query across collections of multi-domain data; enterprise data integration platforms require significant technical expertise and effort from the user; technical tools for data cleaning and integration (e.g. in (Gonzalez et al. 2010), (Huynh and Mazzocchi )) require some technical skills and lack semantic depth to be able to answer complicated queries. QuerioCity uses and augments technologies from the fields of Linked Data and Semantics-based Integration. We are tapping on research output from the fields of Pay-asyou-go data integration (based on non-expert input) (Bizer et al. 2009), (Madhavan et al. 2007), RDF stores, Information provenance and Anonymization.
