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 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. Current decentralized systems still focus on data and knowledge as their main resource. Feasibility of these systems relies basically on P2P (peer-to-peer) techniques and the support of agent systems with scaling and decentralized control. Synergy between grids, P2P systems, and agent technologies is the key to data- and knowledge-centered systems in large-scale environments. This, the 42nd issue of Transactions on Large-Scale Data- and Knowledge-Centered Systems, consists of five revised selected regular papers, presenting the following topics: Privacy-Preserving Top-k Query Processing in Distributed Systems; Trust Factors and Insider Threats in Permissioned Distributed Ledgers: An Analytical Study and Evaluation of Popular DLT Frameworks; Polystore and Tensor Data Model for Logical Data Independence and Impedance Mismatch in Big Data Analytics; A General Framework for Multiple Choice Question Answering Based on Mutual Information and Reinforced Co-occurrence; Rejig: A Scalable Online Algorithm for Cache Server Configuration Changes.Transactions on Large-Scale Data- and Knowledge-Centered Systems,1869-1994 ;11860Computer communication systemsComputer system failuresComputer securityOperating systems (Computers)Logic designComputersComputer Communication Networkshttps://scigraph.springernature.com/ontologies/product-market-codes/I13022System Performance and Evaluationhttps://scigraph.springernature.com/ontologies/product-market-codes/I13049Systems and Data Securityhttps://scigraph.springernature.com/ontologies/product-market-codes/I28060Operating Systemshttps://scigraph.springernature.com/ontologies/product-market-codes/I14045Logic Designhttps://scigraph.springernature.com/ontologies/product-market-codes/I12050Information Systems and Communication Servicehttps://scigraph.springernature.com/ontologies/product-market-codes/I18008Computer communication systems.Computer system failures.Computer security.Operating systems (Computers).Logic design.Computers.Computer Communication Networks.System Performance and Evaluation.Systems and Data Security.Operating Systems.Logic Design.Information Systems and Communication Service.006.312Hameurlain Abdelkaderedthttp://id.loc.gov/vocabulary/relators/edtWagner Rolandedthttp://id.loc.gov/vocabulary/relators/edtMiAaPQMiAaPQMiAaPQBOOK996466297903316Transactions on Large-Scale Data- and Knowledge-Centered Systems XLII2537332UNISA
