The LNCS magazine Transactions on Large-Scale information- and Knowledge-Centered platforms makes a speciality of facts administration, wisdom discovery and data processing, that are center and scorching themes in computing device technology. because the Nineties, the net has turn into the most driver in the back of software improvement in all domain names. a rise within the call for for source sharing throughout diverse websites hooked up via networks has ended in an evolution of information- and knowledge-management platforms from centralized structures to decentralized platforms permitting large-scale disbursed purposes delivering excessive scalability. present decentralized structures nonetheless specialize in facts and information as their major source. Feasibility of those structures is based primarily on P2P (peer-to-peer) ideas and the help of agent platforms with scaling and decentralized keep watch over. Synergy among grids, P2P platforms and agent applied sciences is the major to info- and knowledge-centered structures in large-scale environments. This, the seventeenth factor of Transactions on Large-Scale facts- and Knowledge-Centered platforms, comprises prolonged and revised types of 5 papers, chosen from the 24 complete and eight brief papers provided on the fifteenth foreign convention on information Warehousing and data Discovery, DaWaK 2013, held in Prague, The Czech Republic, in August 2013. Of the 5 papers, conceal facts warehousing facets regarding question processing optimization in complex structures, particularly Map decrease and parallel databases, and 3 conceal wisdom discovery, in particular the causal community inference challenge, dimensionality relief, and the quality-of-pattern-mining task.
