Recently, there has been a growing need for integrating legacy relational databases with semantic web ontologies, however, experience in building such applications has revealed a gap between semantic web languages and relational data model. We present a formal mapping system to bridge the gap and study the problem of reasoning and query answering using view underlying the mapping system. Partic...

BACKGROUND There is great concern within health surveillance, on how to grapple with environmental degradation, rapid urbanization, population mobility and growth. The Internet has emerged as an efficient way to share health information, enabling users to access and understand data at their fingertips. Increasingly complex problems in the health field require increasingly sophisticated computer...

The Murray-Darling Basin Authority (MDBA) is a Commonwealth agency responsible for the sustainable management of water resources in the Murray-Darling Basin. The Authority has identified the need for web mapping infrastructure to provide online access to the Authority’s spatial information via discovery, access and publishing tools. In line with the requirement to harmonise the Authority’s onli...

There has been a lot of discussion in the community concerning the relationship between Web and Grid Services. This document presents an analysis of the Grid architecture and its relationship to the Web Services Architecture. It presents our views on the current version of the OGSI specification and then goes on to propose a different mapping of the Grid infrastructure requirements to Web Servi...

Interpreting Semantic Web Data by different human experts can end up in scenarios, where each expert comes up with different and conflicting ideas what a concept can mean and how they relate to other concepts. Software agents that operate on the Semantic Web have to deal with similar scenarios where the interpretation of Semantic Web data that describes the heterogeneous sources becomes contrad...

This contribution presents the "mapping service environmental noise Schleswig-Holstein": The main component of this web platform consists of a WebGIS with strategic noise maps ("Noise Atlas"). The system was developed in order to support the demands for the first period of the EC Environmental Noise Directive in 2007. The Noise Atlas was since then enhanced continuously, the additions include a...

Software professionals often face trouble when developing software products as it is a highly dynamic, knowledge-intensive complex process. The success of the software process heavily depends on the people involved, among other factors, making their education and training an interesting topic for research. The purpose of this study is to structure and characterize the state of the practice on s...

In this paper, we discuss the musical potential of COMPath an online map based music-making tool as a novel and unique interface for interactive music composition and performance. COMPath provides an intuitive environment for creative music making by sonification of georeferenced data. Users can generate musical events with simple and familiar actions on an online map interface; a set of local ...

We focus on Θ-rich and almost Θ-rich words over a finite alphabet A, where Θ is an involutive antimorphism over A∗. We show that any recurrent almost Θ-rich word u is an image of a recurrent Θ′-rich word under a suitable morphism, where Θ′ is also an involutive antimorphism. Moreover, if the word u is uniformly recurrent, we show that Θ′ can be set to the reversal mapping. We also treat one spe...
