Abstract:

The aim of the thesis is to investigate the topic of semantic under-determinacy, i.e. the failure of the semantic content of certain expressions to determine a truth-evaluable utterance content. In the first part of the thesis, I engage with the problem of setting apart semantic under-determinacy as opposed to other phenomena such as ambiguity, vagueness, indexicality. As I will argue, the feature that distinguishes semantic under-determinacy from these phenomena is its being explainable solely in terms of under-articulation. In the second part of the thesis, I discuss the topic of how communi

Abstract:

The thesis comprises three foundational studies on the topics named in its title, together with an introduction. Ch. 1 argues against a popular combination of views in the philosophy of language: Propositionality, which says that the semantic values of natural language sentences (relative to contexts) are the propositions they express (in those contexts) and Compositionality, which says that the semantic value of a complex expression of a natural language (in a context) is determined by the semantic values its immediate constituents have (in that same context) together with their syntactic mod

"Similarity is a central cognitive mechanism for humans which enables a broad range of perceptual and abstraction processes, including recognizing and categorizing objects, drawing parallelism, and predicting outcomes. It has been studied computationally through models designed to replicate human judgment.

We model both general and relational similarity using connectivity between concepts within semantic networks. Our first contribution is to model

Abstract:

The World Wide Web (WWW) is intended for humans to create and share documents. However, it does not support machine-processable data and automated processing. The Semantic Web is an extension to the WWW and can overcome its shortcomings. The Semantic Web provides the technology for creating and sharing data in machine-processable semantics. As a result, the data can be used and shared in effective ways between cross applications. In this thesis, we investigate the Semantic Web technologies for context-based hyperlink creation and personalization. Two different contributions are presented using

Abstract:

This thesis defends Semantic Pluralism, the view that sentences express sets of propositions in context. It puts forward two arguments against Contextualism, the main opposing view, on which each sentence expresses exactly one proposition in context. It spells out two versions of Pluralism: Flexible Pluralism, which takes most sentences to be context-sensitive, and Strong Pluralism, which denies that context-sensitivity is widespread. And it defends Flexible Pluralism and Strong Pluralism from a number of objections.

Abstract:

The difficulty of semantic multimedia analysis can be attributed to the extended diversity in form and appearance exhibited by the majority of semantic concepts and the difficulty to express them using a finite number of patterns. In meeting this challenge there has been a scientific debate on whether the problem should be addressed from the perspective of using overwhelming amounts of training data to capture all possible instantiations of a concept, or from the perspective of using explicit knowledge about the concepts’ relations to infer their presence.

Abstract:

Visual search requires participants to search for a pre-specified target amongst a number of distractors. According to theories of visual search, attention is directed towards the target through a combination of stimulus-driven (bottom-up) and goal-driven (top-down) means. For example, when searching for a red car, top-down attention can prepare the visual system to prioritise items with matching visual properties to the target, e.g., red objects. Theories of visual search support guidance according to visual properties, including the Guided Search model (Wolfe, 1994) and Attentional Engagemen

The correct semantic interpretation of mathematical formulae in electronic mathematical documents is an important prerequisite for advanced tasks such as search, accessibility or computational processing. Especially in advanced maths, the meaning of characters and symbols is highly domain dependent, and only limited information can be gained from considering individual formulae and their structures. Although many approaches have been proposed for semantic interpretation of mathematical formulae, most of them rely on the limited semantics from maths representation languages whereas very few use

In order to understand how semantic information is processed in a wider context, the first goal of this thesis was to determine whether Swedish pre-school children are able to comprehend semantic context and if that context is semantically built up over time. The second goal was to investigate how the brain distributes attentional resources by means of brain activation amplitude and processing type.

A working hypothesis used in the theoretical analysis is that classification of documents is a process that involves translations between statements in different languages, both natural and artificial.

By uttering a sentence that encodes p, the speaker says that p. Communication is successful only if the audience identifies the proposition that the speaker intends to communicate, which is achieved by decoding the uttered sentence in accordance with the conventions of L. A consequence of the Encoding Model has been the proliferation of underdetermination arguments, each of which concludes against some linguistic theory

Medical professionals spend more time on getting the right information at the right moment, which is already available on intranet/internet. Evaluating the literature is controversial but interesting debates on ontology and se

Abstract:

Universal Business Language (UBL) is an initiative to develop common business document schemas to provide standardization in the electronic business domain. However, businesses operate in different industry, geopolitical, and regulatory contexts and consequently they have different rules and requirements for the information they exchange. In this thesis, we provide semantic enrichment mechanisms for UBL that (i) allow automated customization of document schemas in response to contextual needs and (ii) maintain interoperability among different schema versions. For this purpose, we develop ont

Abstract:

Interoperability between Geographic Information System (GIS) of different infrastructure companies is still a problem to be handled. Infrastructure companies deal with many operations as a part of their daily routine such as a regular maintenance, or sometimes they deal with unexpected situations such as a malfunction due to natural event, like a flood or an earthquake. These situations may affect all companies and affected infrastructure companies response to these effects. Responses may result in consequences and in order to model these consequences on GIS, GISs are able to share information

Abstract:

The principal aim of this thesis is to assess the view that the formal properties of sentences of natural languages encode truth-conditions. The question I pursue is whether truth-conditional semantic theories are capable of accounting for the various ways in which contextual factors contribute to the determination of the truth-conditional content of sentences. The thesis will assess and evaluate three different approaches standard contemporary truth-conditional semanticists have set forth in response to what I shall refer to as the challenge from pervasive context sensitivity, which is essent

Abstract:

Avec le développement rapide des technologies permettant la collecte et l’échange des données géospatiales, la quantité de bases de données géospatiales disponibles est en constante augmentation. Ces bases de données géospatiales représentent souvent une même réalité géographique de façon différente, et sont, par conséquent, sémantiquement hétérogènes. Afin que les utilisateurs de différentes bases de données puissent échanger des données et collaborer dans un but commun, ils doivent avoir une compréhension commune de la signification des données échangées et résoudre ces hétérogénéités, c’est

Abstract:

L'objectif de cette thèse est d'étudier le développement des mécanismes sous-tendant l'exploration d'une scène visuelle. Les résultats montrent que les stratégies d'attention ambiante et focale émergent vers l'âge de 12 mois. La saillance détermine davantage les mouvements oculaires chez les enfants de moins de 6 ans que chez les plus âgés. En outre, les objets sémantiquement inconsistants avec le contexte visuel attirent similairement le regard des jeunes enfants et des adultes. Cependant, seuls les enfants sont plus rapidement attirés par les objets à saillance élevée que par ceux à saillanc

Com os avanços dos processos da microeletrônica temos dispositivos menores e com maior poder de computação e comunicação. Um Ambiente Pervasivo contém diferentes dispositivos, tais como sensores, atuadores, eletroeletrônicos e dispositivos móveis que interagem com a pessoa de forma natural ao conhecer o contexto. A diversidade de dispositivos e informações do Ambiente Pervasivo introduz um problema de interoperabilidade. Um Ambiente Pervasivo é dinâmico devido à mobilidade do usuário, a variedade de dispositivos. Neste trabalho, é proposto um modelo semântico de contexto para permitir interope
