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 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 volume, the 23rd issue of
Transactions on Large-Scale Data- and Knowledge-Centered Systems,focuses on information and security
engineering. It contains five revised and extended papers selected from the
proceedings of the First International Conference on Future Data and Security
Engineering, FDSE 2014, held in Ho Chi Minh City, Vietnam, November 19-21,
2014. The titles of the five papers are as follows: A Natural Language
Processing Tool for White Collar Crime Investigation; Data Leakage Analysis of
the Hibernate Query Language on a Propositional Formulae Domain; An Adaptive
Similarity Search in Massive Datasets; Semantic Attack on anonymized Transactions;
and Private Indexes for Mixed Encrypted Databases.
