The LNCS journal Transactions on Large-Scale Data- and
Knowledge-Centered Systems focuses on data management, knowledge
discovery, and knowledge processing, which are core and hot topics in
computer science. Since the 1990s, the Internet has become the main
driving force behind application development in all domains. An increase
in the demand for resource sharing (e.g., computing resources, services,
metadata, data sources) across different sites connected through
networks has led to an evolution of data- and knowledge-management
systems from centralized systems to decentralized systems enabling
large-scale distributed applications providing high scalability.
This, the 45th issue of Transactions on Large-Scale Data- and
Knowledge-Centered Systems, contains eight revised selected regular
papers. Topics covered include data analysis, information extraction,
blockchains, and big data.
