Book Announcement: Semantic Technologies for Distributed Information Systems
Abstract: In this book we show how semantic technologies - and in particular the use of ontologies - can be employed to address a number of typical challenging characteristics in distributed information systems: (1) the heterogeneity of nodes, i.e. discrepancies in the way the data is modeled and represented, (2) dynamics, i.e. changes in the structure of the system as well as changes in the information at the individual nodes, and (3) autonomy, i.e. the ability of nodes to take decisions independently. First, we illustrate how ontologies with their well-defined semantics allow to interpret the data consistently across nodes and to describe mappings for heterogeneous models and thus provide the means for information integration. Second, we show how ontology evolution allows us to deal with changes in the information in a consistent manner. Third, we present a model for ontology-based coordination to build semantic overlay networks for effective query routing and processing in the absence of centralized control. Throughout the work, we refer to the implementation of the Bibster system - a Peer-to-Peer system for sharing bibliographic metadata - to demonstrate the benefits of semantic technologies.
