Using Expert-Derived Aesthetic Attributes to Help Users in Browsing Image Databases
(2011)Image repositories often contain a large amount of metadata about their content. However many resources, such as photographs, have inherent aesthetic qualities that can be difficult to describe in a semantically consistent ... -
Facilitating Casual Users in Interacting with Linked Data through Domain Expertise
(2011)Linked Data use has expanded rapidly in recent years; however there is still a lack of support for casual users to create complex queries over this Web of Data. Until this occurs, the real benefits of having such rich ... -
Genericity and Metaphoricity Both Involve Sense Modulation
(Springer, 2011)An approach to sense extension tailored for polysemy associated with non-literal language is expanded to include belief revision generally. The relationship between metaphor and genericity as rhetorical devices is discussed, ... -
A Semantic Model for Integrated Content Management, Localisation and Language Technology Processing
(2011)Providers of products and services are faced with the dual challenge of supporting the languages and individual needs of the global customer while also accommodating the increasing relevance of user-generated content. ... -
RESULTS OF THE ENUMERATION OF COSTAS ARRAYS OF ORDER 29
(2011)The results of the enumeration of Costas arrays of order 29 are presented: except for 16 arrays out of a total 164, all other arrays found are accounted for by the Golomb and Welch construction methods. These 16 arrays, ... -
Using Pseudo Feedback to Improve Cross-Lingual Ontology Mapping
(Springer, 2011)Translation techniques are often employed by cross-lingual ontology mapping (CLOM) approaches to turn a cross-lingual mapping problem into a monolingual mapping problem which can then be solved by state of the art monolingual ... -
Integrated Language Technology as part of Next Generation Localisation
(2009)This paper describes one component of a large research project involving industry-academia collaboration between four Irish universities and nine Irish and multinational industry partners, all collaborating to develop 'Next ... -
Mean-Shift Tracking for Surveillance: Evaluations and Enhancements
(University of Dublin, University of Dublin, Trinity College, 2011)Mean-shift tracking is a technique for following an object of interest as it moves through a video sequence. It is a gradient ascent approach that models the image region to be tracked by its colour histogram. In this ... -
Report on an Arctic summer DTN trial
(Springer, 2011)Delay- and disruption-tolerant networking (DTN) is an emerging area of networking research that will benefit from real-world trials and testbeds. We describe a week long DTN trial carried out during the summer of 2009 in ... -
Towards Understanding the Effects of Neutrality on the Sudoku Problem
(ACM Press, 2007)Over the last years, researchers have added neutrality in the evolutionary search in the hope that it can aid evolution. In this paper, we study the presence of neutrality that is already and to do so, we analised the ... -
How and Why a Bit-Wise Neutrality with and without Locality Affects Evolutionary Search
(ACM Press, 2007)Despite the vast work on neutrality, there are not general conclusions on its effects. In this paper we make an effort to understand how neutrality in uences evolution. For this purpose we will use a type of neutrality ... -
Towards Understanding the Effects of Locality in GP
(IEEE Press, 2009)Locality - how well neighbouring genotypes correspond to neighbouring phenotypes - has been defined as a key element in Evolutionary Computation systems to explore and exploit the search space. Locality has been studied ... -
Investigating Mapping Order in ðGE
(IEEE Press, 2010)We present an investigation into the genotypephenotype map in Position Independent Grammatical Evolution (?GE). Previous studies have shown ?GE to exhibit a performance increase over standard Grammatical Evolution ... -
Implementing an Intuitive Mutation Operator for Interactive Evolutionary 3D Design
(IEEE Press, 2010)Locality - how well neighbouring genotypes correspond to neighbouring phenotypes - has been described as a key element in Evolutionary Computation. Grammatical Evolution (GE) is a generative system as it uses grammar ... -
Tree-Adjunct Grammatical Evolution
(IEEE Press, 2010)In this paper we investigate the application of tree-adjunct grammars to grammatical evolution. The standard type of grammar used by grammatical evolution, context-free grammars, produce a subset of the languages that ... -
Comparing the Performance of the Evolvable PiGrammatical Evolution Genotype Phenotype Map to Grammatical Evolution in the Dynamic Ms. Pac-Man Environment
(IEEE Press, 2010)In this work, we examine the capabilities of two forms of mappings by means of Grammatical Evolution (GE) to successfully generate controllers by combining high-level functions in a dynamic environment. In this work we ... -
Defining Locality in Genetic Programming to Predict Performance
(IEEE Press, 2010)A key indicator of problem difficulty in evolutionary computation problems is the landscape?s locality, that is whether the genotype-phenotype mapping preserves neighbourhood. In genetic programming the genotype ... -
The Effects of Constant and Bit-Wise Neutrality on Problem Hardness, Fitness Distance Correlation and Phenotypic Mutation Rates.
(2011)Kimura?s neutral theory of evolution has inspired researchers from the evolutionary computation community to incorporate neutrality into Evolutionary Algorithms (EAs) in the hope that it can aid evolution. The effects of ... -
Choosing between Axioms, Rules and Queries: Experiments in Semantic Integration Techniques
(2011)When using semantic technologies developers are frequently confused about which specific inferencing technique is best to use for a given problem. As an initial step towards identifying "best practices" for users ... -
A Semantic Monitoring and Management Framework for End-to-end Services
(IEEE, 2011)Modern distributed applications and communication services have become increasingly complex, composed of diverse heterogeneous sub-systems, and it is progressively more unrealistic that the users of these systems will ...
