(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2014)This thesis presents an investigation of whether there is evidence of gender bias in the coverage of politicians in Irish newspapers. Text-analysis techniques including natural language processing and machine learning are ... -
Measuring social capital in online communities
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2015)Online communities are a popular and useful means for people to meet, share information, and learn more about a topic of interest to them. However, communities risk disintegration if there are insufficient social connections ... -
Key challenges in the current TB & HIV information system in South Africa : a case study in Khayelitsha, Western Cape
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2015)South Africa has one of the most serious human immunodeficiency virus (HIV) / and tuberculosis (TB) epidemics in the world, with high incidence, prevalence and co-infection rates. Information is at the heart of managing ... -
Hardware support for power and area efficient construction of high-quality bounding volume hierarchies
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2014)Rendering methods basal on ray-tracing hold the promise of great realism for interactive applications. However, these algorithms still involve a considerable computational cost relative to the capabilities of today�۪s ... -
Content and context in conversations : the role of social and situational signals in conversation structure
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2016)The increasing growth of multimodal material creates, nowadays, a renewed interest in innovative approaches to information extraction from meetings and multiparty conversations; those approaches make use of various multimodal ... -
An investigation of and a hybrid recommender system for evaluating adaptive E-Learning systems
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2015)A key problem with research in the field of adaptive systems is the inconsistency of evaluation applied to such systems. A fact that is well established by expert evaluators is that adaptive systems cannot be evaluated as ... -
Generating sentiment lexica : evaluating approaches with genetic algorithms and particle swarm optimization
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2014)This thesis examines the application of sentiment analysis towards financial news. The primary goal within the field of sentiment analysis is to develop a methodology by which the sentiment or emotional view being expressed ... -
Interheap GC
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2015)Garbage collection is the automation of memory management for computer programs. It is an important feature of both the Java and .NET environments, and it is a key component of the runtime system for many high level language ... -
Space & time efficient sparse matrix transpose
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2015)Matrix operations are fundamental to linear algebra and have many important applications in areas such as sinmlation of physical systems, economic modeling, linear optimization and numerical analysis. One of the fundamental ... -
The development of a stages of growth model for information systems within government departments
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2014)This dissertation proposes a stages of growth model for the use of information and communications technology/information systems in large government departments. The stages of growth model presented maps the changes through ... -
Enforcing cooperation between nodes in mobile ad hoc networks
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2013)Traditional infrastructure-based networks are formed around an infrastructure of static, dedicated components that connect the individual end points such as desktop computers and servers. The exponential rise in the number ... -
Ontology and information retrieval : the case of the fine arts
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2012)This thesis explores methods of computational ontology for information retrieval in a knowledge rich domain. The example case we selected for our study is the domain of the fine arts. Various aspects were under examination, ... -
Learner perceptions of successful engagement in undergraduate computer science education : a grounded theory
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2013)Computer science degree programs have proliferated due to the demands of industry and the pressures placed on higher education institutions by national governments. In tandem with this, the technological familiarity presumed ... -
Effects of social structure on establishing lexical conventions in a computational model of task-oriented primeval dialogue
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2013)In the field of language evolution, the only way of obtaining empirical data for most of its parts is with the help of computational models and simulations. As a consequence, a large number of different modelling approaches ... -
Trust as a form of defeasible reasoning
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2008)Computational models of Trust have recently emerged as a way to exploit the human notion of trust in open and collaborative environments. This thesis provides a novel computational model of trust based on defeasible ... -
Authentication and accounting for network services in next-generation mobile networks
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2005)Mobile communications technologies are in a constant state of flux. They have evolved from simple one-way radio communications systems, to today’s third-generation networks that support digital signaling and multimedia ... -
Parasitic routing : using social network analysis for routing in disconnecting delay-tolerant MANETs
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2007)Message delivery in sparse Mobile Ad hoc Networks (MANETs) is difficult due to the fact that the network graph is rarely (if ever) connected. As a consequence, a full end-to-end path between nodes may not exist at any given ... -
