Semantic knowledge representation and analysis
… speak the same language. This thesis presents a semantic knowledge representation that incorporates this fuzziness and context-dependence of concepts. In particular, this thesis provides several algorithms for learning the meaning behind text by using a dataset of experiences to build up an …

VISUAL AND SEMANTIC KNOWLEDGE TRANSFER FOR NOVEL TASKS
… can help a model effectively transfer visual and semantic knowledge learned from \emph{source} task to \emph{target} task. More specifically, first we develop a model that learns a uniform visual representation of semantic attributes, which help alleviate the domain shift problem in Zero-Shot …

Social-semantic knowledge and behavioural changes in frontotemporal dementia
Key insights into the organisation of semantic memory in the brain have been derived from semantic dementia, a subtype of frontotemporal dementia (FTD) associated with a degradation of conceptual knowledge following atrophy in the anterior temporal lobes (ATLs). Recent research in FTD has begun to …

Cognitive development and the acquisition of semantic knowledge in Northern Belize
… cognitive development and the acquisition of semantic knowledge conducted in Corozal Town, Belize. Historical and ethnographic accounts of the area precede this presentation. A research sample of children between the ages of 5 and 17 (N= 90) was selected from among Spanish and Belizean Creole …

Assessment Of The Semantic Knowledge Network In Older Adults With Familial History Of Alzheimer's Disease
… of examining the temporal gradient for long-term semantic knowledge in identification of such individuals. The assessment of the temporal gradient within varying levels of knowledge specificity, however, has received considerably less attention. In this study, we aimed to contrast accuracy and …

The role of declarative memory in the acquisition of conceptual semantic knowledge in Autism Spectrum Disorder
… The relation between familiarity and conceptual semantic knowledge was investigated whilst controlling for visuo-perceptual abilities and fluid intelligence. Findings confirmed an association between familiarity and conceptual semantic knowledge in the ASD population as well as the use of …

Semantic optimisation in datalog programs
… necessary to improve the efficiency of programs. Semantic optimisation uses meta-knowledge describing the data in the database to optimise queries and rules, aiming to reduce the resources required to answer queries. In this thesis, I analyse prior work that has been done on semantic optimisation …

Understanding Semantic Implicit Learning through distributional linguistic patterns: A computational perspective
… provides a computational perspective on Semantic Implicit Learning (SIL). It puts forward the idea that SIL does not depend on semantic knowledge as classically conceived but upon semantic-like knowledge gained through distributional analysis of massive linguistic input. Using methods …

Contributions of Signal-detection Mechanisms and Semantic Memory Representations to Famous Name Recognition
… In Chapter 3, I studied the contributions of semantic knowledge to famous name familiarity, with a focus on recognition experiences in which ‘names ring a bell’. I revealed that despite the fact that participants understand this recognition experience to reflect situations where names are …

USE OF LANGUAGE TECHNOLOGY TO IMPROVE MATCHING AND RETRIEVAL IN TRANSLATION MEMORY
Current Translation Memory (TM) tools lack semantic knowledge while matching. Most TM tools compute similarity at the string level, which does not take into account semantic aspects in matching. Therefore, semantically similar segments, which differ on the surface form, are often not retrieved. In …

The feeling of knowing for names of faces
… their familiarity with each face and to retrieve semantic knowledge, where possible, whilst making a FOK judgement and a tip-of-the-tongue (TOT) judgement. The results provide some support for both theories; however, the results suggest that neither theory can account solely for the basis of the …

Global Voices: A Student-Centered Guide to Teaching English as an International Language
… “objective” grammatical, phonological and semantic knowledge to passive students does not serve the interest or needs of the estimated 1.5 billion students learning English in today’s interconnected, dynamic world. Critical theories and approaches such as critical pedagogy, critical …

Toward ontological visual understanding
Lack of human prior knowledge is one of the main reasons that the semantic gap still remains when it comes to automatic multimedia understanding. One difference between the human cognition system and state-of-the-art machine vision algorithms is that the former possesses and uses high-level …
