Event and map content personalisation in a mobile and context-aware environment. (2008)
Thesis
BIERIG, R., 2008. Event and map content personalisation in a mobile and context-aware environment. Robert Gordon University, PhD thesis.

Effective methods for information access are of the greatest importance for our modern lives “ particularly with respect to handheld devices. Personalisation is one such method which models a users characteristics to deliver content more focused to t...

The asymptotic behavior of a limited dependencies language model. (2008)
Conference Proceeding
HOENKAMP, E., BRUZA, P., HUANG, Q. and SONG, D. 2008. The asymptotic behavior of a limited dependencies language model. In Hoenkamp, E., De Cock, M. and Hoste, V. (eds.) Proceedings of 8th Dutch-Belgian information retrieval workshop 2008 (DIR 2008), 14-15 April 2008, Maastricht, Netherlands. Enschede: Neslia Paniculata, pages 59-64.

Intuitively, any ‘bag of words’ approach in IR should benefit from taking term dependencies into account. Unfortunately, for years the results of exploiting such dependencies have been mixed or inconclusive. To improve the situation, this paper shows...

An inductive logic programming approach to learning which uORFs regulate gene expression. (2008)
Thesis
SELPI 2008. An inductive logic programming approach to learning which uORFs regulate gene expression. Robert Gordon University, PhD thesis.

Some upstream open reading frames (uORFs) regulate gene expression (i.e. they are functional) and can play key roles in keeping organisms healthy. However, how uORFs are involved in gene regulation is not het fully understood. In order to get a compl...

Towards a belief-revision-based adaptive and context-sensitive information retrieval system. (2008)
Journal Article
LAU, R.Y.K., BRUZA, P. and SONG, D. 2008. Towards a belief-revision-based adaptive and context-sensitive information retrieval system. ACM transactions on information systems [online], 26(2), article number 8. Available from: https://doi.org/10.1145/1344411.1344414

In an adaptive information retrieval (IR) setting, the information seekers' beliefs about which terms are relevant, or non-relevant, will naturally fluctuate. This article investigates how the theory of belief revision can be used to model adaptive I...

Escaping local optima: constraint weights vs value penalties. (2007)
Conference Proceeding
BASHARU, M., ARANA, I. and AHRIZ, H. 2008. Escaping local optima: constraint weights vs. value penalties. In Bramer, M., Coenen, F. and Petridis, M. (eds.) Research and development in intelligent systems XXIV: technical proceedings of the 27th Annual international conference of the British Computer Society's Specialist Group on Artificial Intelligence (SGAI) (AI-2007): innovative techniques and applications of artificial intelligence, 10-12 December 2007, Cambridge, UK. London: Springer [online], pages 51-64. Available from: https://doi.org/10.1007/978-1-84800-094-0_5

Constraint Satisfaction Problems can be solved using either iterative improvement or constructive search approaches. Iterative improvement techniques converge quicker than the constructive search techniques on large problems, but they have a propensi...
