AG Netzbasierte Informationssysteme

The DigiPolis project here at AG NBI is developing a Self-organized Semantic Storage Service (“S4″). A survey paper written by NBI staff members Hannes Mühleisen, Tilman Walther and Prof. Robert Tolksdorf was just published in the International Journal of Web Information Systems. The publication is titled “A survey on self-organized semantic storage”, here the abstract:

Purpose – The purpose of this paper is to show the potential of self-organized semantic storage services. The semantic web has provided a vision of how to build the applications of the future. A software component dedicated to the storage and retrieval of semantic information is an important but generic part of these applications. Apart from mere functionality, these storage components also have to provide good performance regarding the non-functional requirements scalability, adaptability and robustness. Distributing the task of storing and querying semantic information onto multiple computers is a way of achieving this performance. However, the distribution of a task onto a set of computers connected using a communication network is not trivial. One solution is self-organized technologies, where no central entity coordinates the system’s operation.

Design/methodology/approach – Based on the available literature on large-scale semantic storage systems, the paper analyzes the underlying
