Interfaces to data models: taking a step backwards
Presentation / Conference Contribution
Barclay, P., Crerar, A., & Davidson, K. (1994, July). Interfaces to data models: taking a step backwards. Presented at Second International Workshop on Interfaces to Database Systems, Lancaster, UK

This paper is concerned with data modelling and the question of how to improve the quality of software tools to provide more effective support for the modeller. With the increasing interest in building intelligent interfaces to databases and associat... Read More about Interfaces to data models: taking a step backwards.

TOTEM: an Interactive Tool for Creative Data Modelling
Presentation / Conference Contribution
Crerar, A., Barclay, P. J., & Watt, R. (1996, July). TOTEM: an Interactive Tool for Creative Data Modelling. Presented at 3rd International Workshop on Interfaces to Databases, Napier University, Edinburgh

Data modelling is a crucial and early step in the design of all but the most trivial database systems. Although a fundamental skill for information systems designers, data modelling is not easy to do well and novices are known to have considerable di...

Evolved Bayesian Network models of rig operations in the Gulf of Mexico
Presentation / Conference Contribution
Fournier, F. A., McCall, J., Petrovski, A., & Barclay, P. J. (2010, July). Evolved Bayesian Network models of rig operations in the Gulf of Mexico. Presented at 2010 IEEE Congress on Evolutionary Computation (CEC), Barcelona, Spain

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.

The Prometheus taxonomic database
Presentation / Conference Contribution
Raguenaud, C., Kennedy, J., & Barclay, P. (2000, November). The Prometheus taxonomic database. Presented at IEEE International Symposium on Bio-Informatics and Biomedical Engineering, Arlington, VA, USA

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.
