Viewer-Based Directional Querying For Mobile Applications, Keith Gardiner, James Carswell

Conference papers

With the steady and fast advancements in the integration of geographic information systems and mobile location-based services, interest in exploiting this technology for Cultural Heritage (CH) data sharing has become apparent. In this area there has been an increasing need to integrate positional information with non-positional data and add a spatial dimension to the definition of a users “context”. In this paper we describe an implementation of a viewer-based directional query processor that operates on an Oracle Spatial database. The spatial position and orientation are taken from the viewer’s perspective. Using this frame of reference a view-port is defined in …

A Framework To Utilise Urban Bus Data For Advanced Data Analysis, Markus Hofmann, Brendan Tierney, Margaret M. O'Mahony

Conference papers

Most urban bus operators collect detailed data on their respective transportation networks using electronic fare collection systems. However, contrary to the opinion of other service industries that this data is a valuable resource, many bus operators have tended not to fully utilise these resources. International experience suggests using innovative technologies and methodologies such as data warehousing, Online Analytical Processing (OLAP), and data mining, to derive the maximum benefit from this data. Still bus operators tend not to keep the full range of data in a form, which is easy to access or utilise, and therefore, are not able to apply …

Agent Chameleons: Agent Minds And Bodies, Brian Duffy, Gregory O'Hare, Alan Martin, John Bradley, Bianca Schoen-Phelan

Conference papers

Agent design has to date concerned itself with the issues pertaining to a single body embedded in a single environment, whether virtual or real. This paper discusses the notion of an agent capable of migrating between information spaces (physical worlds, virtual reality, and digital information spaces). An architecture is presented that facilitates agent migration and mutation within such environments. This will in turn support agent
