Application of evolutionary algorithms to learning evolved Bayesian Network models of rig operations in the Gulf of Mexico (2010)
Presentation / Conference Contribution
Fournier, F. A., Wu, Y., McCall, J., Petrovski, A., & Barclay, P. J. (2010, September). Application of evolutionary algorithms to learning evolved Bayesian Network models of rig operations in the Gulf of Mexico. Presented at 2010 UK Workshop on Computational Intelligence (UKCI), Colchester, UK

The operation of drilling rigs is highly expensive. It is therefore important to be able to identify and analyse variables affecting rig operations. We investigate the use of Genetic Algorithms and Ant Colony Optimisation to induce a Bayesian Network...

The operation of drilling rigs is highly expensive. It is therefore important to be able to identify and analyse factors affecting rig operations. We investigate the use of two Genetic Algorithms, K2GA and ChainGA, to induce a Bayesian Network model... Read More about Evolved Bayesian Network models of rig operations in the Gulf of Mexico.

Interoperable Services for Federations of Database System (2002)
Presentation / Conference Contribution
Roantree, M., Kennedy, J., & Barclay, P. J. (2002). Interoperable Services for Federations of Database System. In A. Caplinskas, & J. Eder (Eds.), Advances in Databases and Information Systems: Fifth East-European Conference ADBIS' 2001

The problems associated with defining interoperable protocols for heterogenous information systems has been the subject of researchers for many years. While numerous solutions have been offered, the problem remains unsolved, mainly due to the distinc... Read More about Interoperable Services for Federations of Database System.

Integrating View Schemata Using an Extended Object Definition Language (2001)
Presentation / Conference Contribution
Roantree, M., Kennedy, J. B., & Barclay, P. J. (2001, September). Integrating View Schemata Using an Extended Object Definition Language. Presented at 9th International Conference, CoopIS 2001, Trento, Italy

View mechanisms play an important role in restructuring data for users, while maintaining the integrity and autonomy for the underlying database schema. Although far more complex than their relational counterparts, numerous object-oriented view mecha... Read More about Integrating View Schemata Using an Extended Object Definition Language.

Using a metadata software layer in information systems integration. (2001)
Presentation / Conference Contribution
Roantree, M., Kennedy, J., & Barclay, P. J. (2001, June). Using a metadata software layer in information systems integration. Presented at CAiSE'01 - Software Engineering meets Information Systems Engineering. Conference, Interlaken, Switzerland

A federated information system requires that multiple (often heterogenous) information systems are integrated to an extent that they can share data. This shared data often takes the form of a federated schema, which is a global view of data taken fro... Read More about Using a metadata software layer in information systems integration..

The Prometheus taxonomic database (2000)
Presentation / Conference Contribution
Raguenaud, C., Kennedy, J., & Barclay, P. (2000). The Prometheus taxonomic database. In Proceedings IEEE International Symposium on Bio-Informatics and Biomedical Engineering (63-70). https://doi.org/10.1109/bibe.2000.889590

M.R. Pullen et al. (2000) have designed a new model of plant taxonomy (called Prometheus); it supports multiple overlapping classifications, and distinguishes the process of naming from classifying. The concepts identified in this taxonomic model nec... Read More about The Prometheus taxonomic database.

Conceptual Modelling for Database User Interfaces (2000)
Presentation / Conference Contribution
Cooper, R., McKirdy, J., Griffiths, T., Barclay, P. J., Paton, N. W., Gray, P., Kennedy, J., & Goble, C. (2000, May). Conceptual Modelling for Database User Interfaces. Presented at Visual Database Systems - VDB5, 2000, Fukuoka, Japan

Model-based user interface development environments show promise for improving the speed of production and quality user interfaces. Such systems usually have seperate descriptions of domain, task and presentation to structure. The Teallach system app... Read More about Conceptual Modelling for Database User Interfaces.

This short paper describes the presentation model used by the Teallach model-based user-interface development environment. Teallach's presentation model provides both abstract and concrete interactors, which are first-class objects that may be freely... Read More about Teallach's presentation model ..

The Prometheus database for taxonomy (2000)
Presentation / Conference Contribution
Raguenaud, C., Kennedy, J., & Barclay, P. (2000, July). The Prometheus database for taxonomy. Presented at Proceedings. 12th International Conference on Scientific and Statistica Database Management

This paper presents the work carried out in the Prometheus project and its motivation, taxonomy. Taxonomy presents challenges to common database systems. Because of its complexity and the necessary treatments applied to its data, common database mode... Read More about The Prometheus database for taxonomy.

A dual-level presentation model for developing user-interfaces. (2000)
Presentation / Conference Contribution
Barclay, P. J., & Kennedy, J. (2000). A dual-level presentation model for developing user-interfaces. In V. Gesu, S. Levialdi, & L. Tarantino (Eds.), Proceedings of the workshop on Advanced Visual Interfaces (151-154)

The visualisation of hierarchical information sets has been a staple of Information Visualisation since the field came into being in the early 1990’s. However, at present, support for visualising the correlations between multiple, overlapping sets of... Read More about A dual-level presentation model for developing user-interfaces..
