<p>This licentiate thesis deals with automatic syntactic analysis, or parsing, of natural languages. A parser constructs the syntactic analysis, which it learns by looking at correctly analyzed sentences, known as training data. The general topic concerns manipulations of the training data in order to improve the parsing accuracy.</p><p>Several studies using constituency-based theories for natural languages in such automatic and data-driven syntactic parsing have shown that training data, annotated according to a linguistic theory, often needs to be adapted in various ways in order to achieve an adequate, automatic analysis. A linguistically sound constituent structure is not necessarily well-suited for learning and parsing using existing data-driven methods. Modifications to the constituency-based trees in the training data, and corresponding modifications to the parser output, have successfully been applied to increase the parser accuracy. The topic of this thesis is to investigate whether similar modifications in the form of tree transformations to training data, annotated with dependency-based structures, can improve accuracy for data-driven dependency parsers. In order to do this, two types of tree transformations are in focus in this thesis.</p><p>The first one concerns non-projectivity. The full potential of dependency parsing can only be realized if non-projective constructions are allowed, which pose a problem for projective dependency parsers. On the other hand, non-projective parsers tend, among other things, to be slower. In order to maintain the benefits of projective parsing, a tree transformation technique to recover non-projectivity while using a projective parser is presented here.</p><p>The second type of transformation concerns linguistic phenomena that are possible but hard for a parser to learn, given a certain choice of dependency analysis. This study has concentrated on two such phenomena, coordination and verb groups, for which tree transformations are applied in order to improve parsing accuracy, in case the original structure does not coincide with a structure that is easy to learn.</p><p>Empirical evaluations are performed using treebank data from various languages, and using more than one dependency parser. The results show that the benefit of these tree transformations used in preprocessing and postprocessing to a large extent is language, treebank and parser independent.</p>

This study briefly reviews both historical and recent conceptualizations of dependency. In particular, it focuses on this concept's applicability to patients with chronic illnesses, especially those with allergies. Type and degree of dependency were seen as an important factor in the approach to the medical and psychological treatment of clinical ecology patients. The purpose of the study was to develop an objective measure of dependency which could quickly identify patients whose dependency conflicts interfere with the treatment process. The study was divided into three phases. In the first phase test responses by 84 inpatients to the CAQ, MMPI, and the HAT as well as historical and demographic data were analyzed by a series of stepwise discriminant analysis. The 53 resulting items were examined for those which most concisely discriminated between the two identified groups (pathologically dependent and nonpathologically dependent). These 15 items were used to test 120 additional patients in phase II. Fourteen items were retained and the coefficients obtained classified the patients in phase I and II with a 98.81 percent and 94.17 percent degree of accuracy respectively. These classification coefficients were used to classify another 30 patients in phase III with a 96.67 percent rate of accuracy. These results provide exceptionally strong support for the hypothesis that group classification can be obtained through the use of an objective screening instrument. The pathologically dependent patients tend to focus on disease, frequently are unemployed, have histories of childhood illnesses, have limited emotional controls, are depressed, ambivalent, and distrustful. Additionally, they experience difficulty establishing goals or accepting personal responsibility. Those patients identified as nonpathologically dependent exemplify the more positive aspects of these traits. The pathologically dependent patients appear to be caught in a dilemma between wellness and satisfaction of dependency needs. While all patients need an organized approach to treatment, the pathologically dependent require an extremely structured repititious approach and may require long term psychological intervention in order to make positive steps toward wellness.

A photograph typically depicts an aspect of the real world, such as an outdoor landscape, a portrait, or an event. The task of creating abstract digital representations of images has received a great deal of attention in the computer vision literature because it is rarely useful to work directly with the raw pixel data. The challenge of working with raw pixel data is that small changes in lighting can result in different digital images, which is not typically useful for downstream tasks such as object detection. One approach to representing an image is automatically extracting and quantising visual features to create a bag-of-terms vector. The bag-of-terms vector helps overcome the problems with raw pixel data but this unstructured representation discards potentially useful information about the spatial and semantic relationships between the parts of the image. The central argument of this thesis is that capturing and encoding the relationships between parts of an image will improve the performance of extrinsic tasks, such as image description or search. We explore this claim in the restricted domain of images representing events, such as riding a bicycle or using a computer. The first major contribution of this thesis is the Visual Dependency Representation: a novel structured representation that captures the prominent region–region relationships in an image. The key idea is that images depicting the same events are likely to have similar spatial relationships between the regions contributing to the event. This representation is inspired by dependency syntax for natural language, which directly captures the relationships between the words in a sentence. We also contribute a data set of images annotated with multiple human-written descriptions, labelled image regions, and gold-standard Visual Dependency Representations, and explain how the gold-standard representations can be constructed by trained human annotators. The second major contribution of this thesis is an approach to automatically predicting Visual Dependency Representations using a graph-based statistical dependency parser. A dependency parser is typically used in Natural Language Processing to automatically predict the dependency structure of a sentence. In this thesis we use a dependency parser to predict the Visual Dependency Representation of an image because we are working with a discrete image representation – that of image regions. Our approach can exploit features from the region annotations and the description to predict the relationships between objects in an image. In a series of experiments using gold-standard region annotations, we report significant improvements in labelled and unlabelled directed attachment accuracy over a baseline that assumes there are no relationships between objects in an image. Finally, we find significant improvements in two extrinsic tasks when we represent images as Visual Dependency Representations predicted from gold-standard region annotations. In an image description task, we show significant improvements in automatic evaluation measures and human judgements compared to state-of-the-art models that use either external text corpora or region proximity to guide the generation process. In the query-by-example image retrieval task, we show a significant improvement in Mean Average Precision and the precision of the top 10 images compared to a bag-of-terms approach. We also perform a correlation analysis of human judgements against automatic evaluation measures for the image description task. The automatic measures are standard measures adopted from the machine translation and summarization literature. The main finding of the analysis is that unigram BLEU is less correlated with human judgements than Smoothed BLEU, Meteor, or skip-bigram ROUGE.

Partimos do pressuposto de que a transferência de valor dos países dependentes para os países centrais é a característica estrutural da situação de dependência e o que impede o desenvolvimento dos países dependentes. Entendemos que a condição de dependência dos países periféricos se adaptou às novas conformações econômicas do mercado mundial e como consequência novas formas de transferência de valor surgiram. A pesquisa se restringiu à análise de dois países latino americanos, Brasil e Argentina, que foram escolhidos por serem as maiores economias do Mercosul e por suas similaridades políticas e econômicas como países dependentes e ao período de 2000 a 2015. O trabalho está dividido em duas partes, sendo que na primeira buscamos apontar dentro do pensamento social latinoamericano o lugar da teoria marxista da dependência e mostrar como a transferência de valores é a sua característica estrutural e na segunda buscamos classificar e analisar essa situação utilizando indicadores macroeconômicos que demonstram as transferências de valor por meio de três agentes: (a) o mercado, (b) o governo e (c) capitalistas privados. Chegamos à conclusão de que, apesar de serem países de renda mais elevada (renda média superior), Brasil e Argentina se comportam como países de renda menor (renda média inferior e até renda baixa) no que se refere às transferências de valor, o que demonstra que são mais vulneráveis e transferem mais valor para os países centrais do que outros países na mesma faixa de renda, ou seja, são países dependentes. / We start this study from the assumption that the transfer of value from the dependent countries to the central ones is the structural characteristic of dependency and what prevents the development of the dependent countries. We understand that the dependency condition of peripheral countries has adapted to the new economic conformations of the world market and, as a consequence, new forms of value transfer have arisen. The research was restricted to the analysis of two Latin American countries, Brazil and Argentina, which were chosen for being the largest economies of MERCOSUR and their political and economic similarities as dependent countries. The analisys is also restrictesd to the period from 2000 to 2015. In the first part of the work we seek to identify within Latin American Social Thought the place of Marxist Theory of Dependence and to show how the transfer of values is its structural characteristic of the dependent countries, and in the second part we seek to classify and analyze this situation using macroeconomic indicators that demonstrate the transfers of value through three agents: (a) the market, (b) the government and (c) private capitalists. We conclude that, despite being higher income countries (upper middle income), Brazil and Argentina behave as lower income countries (lower middle income and even lower income) in terms of transfers of value, which Shows that they are more vulnerable and transfer more value to the central countries than other countries with the same income, so we can say they are dependent countries.

Business Process Management (BPM) is a relatively new development paradigm that takes a high-level approach to coding by leveraging a graphical, “flow chart” aesthetic that allows users to assemble modular tasks into a larger process. The resulting diagrams effectively enshrine the organizations processes into an executable model that provides an objective and transparent view of the process and the activities contained within. In doing so, BPM models serve as both a system to guide employees through proper business procedures as well as documentation of the businesses processes. Similar to most other software development environments, BPM development platforms possess several features intended to address the needs of code versioning, dependency management and impact assessment. However, due to the unique way that development is done in BPM platforms, the more traditional functionality of these features sometimes renders them ineffective and ill suited to the task of BPM development. Changes to lower level reusable components in these BPM models can result in impacts to diverse processes across an organization that are difficult to predict and onerous to locate. There is much room for improvement in BPM development tools. This thesis proposes a new framework for dependency management and impact assessment to improve the usability, effectiveness and efficiency. The framework is composed of a Business Process Component Architecture, a Dependency Data Model and an Upgrade Algorithm which are all used to provide increased visibility over dependent processes and superior guidance during upgrade operations. Several example case scenarios are be used to evaluate our proposed framework. The cases represent progressive degrees of complexity to test the capabilities and robustness of the framework. Overall, the framework was able to appropriately handle the case examples used and showed promise in terms of providing practical effort, time and cost savings for BPM developers. The framework can also provide developers assistance in locating circular dependencies, but is subject to the same limitations as developers when attempting to upgrade these relationships.

O problema da dependência na América Latina foi apontado por um esforço intelectual coletivo ainda no final da década de 1960 e durante a década de 1970. Por uma conjunção de fatores históricos, o debate foi relegado ao esquecimento e toda uma corrente teórica que fez época acabou ficando esquecida. Ao longo dos anos 1990 e, principalmente, a partir da década seguinte, as exigências históricas impulsionaram toda uma nova geração de pesquisadores a retomar o fio desse debate. Inserindo-se nesse processo, esse trabalho se propõe a retomar a Teoria da Dependência a partir de uma perspectiva que fora pouco tratada: o debate sobre a ideologia dominante na região. O trajeto proposto para estudar esse objeto consiste em debater, dentro da tradição marxista, o conteúdo do conceito de ideologia; retomar o debate sobre a dependência, a partir da caracterização do conceito e de sua periodização; para enfim, entender o seu objeto. A proposta parte do pressuposto de que a reprodução do capitalismo dependente, apresenta o desafio de compreender a particularidade da ideologia das classes dominantes que ao mesmo tempo são subordinadas no circuito capitalista internacional. A hipótese que norteia o trabalho é a de que, tal como o capitalismo dependente se reproduz de modo particular, o mesmo ocorre com a ideologia dominante nos países dependentes. / The problem of dependency in Latin America was indicated by a collective intellectual effort, still in the late 1960s and during the 1970s.

Understanding the mechanical properties and deformation characteristics of nanoscale metallic nanopillars and wires is a significant concern for designing reliable small devices that must resist loads in service. This thesis aims to extend understanding of the size dependent behaviour of nanopillars and wires in compression and tension by investigating their mechanical properties and deformation characteristics. Single crystal bcc pillars were fabricated by focussed ion beam (FIB) machining from Fe, Nb, V, Ta, Mo, W and Cr, as well as the ferrite (bcc) and austenite (fcc) components of a duplex stainless steel (DSS). These were tested in compression over a range of test temperatures from 193 K to 393 K using various types of nanomechanical devices. The effect of sample size (pillar diameter) on the strength was investigated and found to increase with decreasing pillar size. In bcc metals, the yield or flow stress, 􀀂􀀖, is inversely proportional with some power of the pillar diameter, d. In bcc metals tested, the power-law exponent, n, were found in the range of between -0.23 to -0.63, showing a less pronounced size effect than found for fcc pillars. The power-law exponent for bcc pillar deformation is also temperature dependent and was found to scale with the ratio of test temperature, Ttest to the critical temperature for screw dislocation mobility, Tc, of the bcc metal (T*= Ttest / Tc). It is notable that the size effect exponent weakens (approaches 0) as T* decreases. However, when the experiments are carried out at temperatures close to or just above Tc, the power-law exponents approaches the value reported in the literature for a range of fcc metals (-1 < n < -0.6). The variation in the power-law exponent observed for bcc metals can be explained by the change in mobility of thermally activated screw dislocations. Their mobility can be modelled by a threshold or lattice friction stress. If this friction stress is introduced into the empirical equation that relates the strength of fcc metal pillars to their diameter, a strong correlation between size effect exponent, the normalised test temperature (T*) and friction stress is obtained. It was found that the friction stress values (Fe, Nb and V) increase as Ttest decreases from 296 to 193 K. When the pillar diameter decreases, the friction stress would be more easily overcome due to the increase in surface-to-volume ratio. The contribution of lattice friction stress on the strength is higher at larger pillars than those for nanopillars. Thus, the divergence between best fit lines has become more apparent at micron-sized pillars, resulting in weaker size effects. Furthermore, the transition in deformation morphology from localized to wavy deformation was only found in Fe pillars, as the Ttest decreased from 296 to 193 K, further revealing that temperature has also strong influence on deformation behaviours of bcc pillars.

Les logiciels évoluent au fil du temps avec la modification, l'ajout et la suppression de nouvelles classes, méthodes, fonctions, dépendances. Une conséquence est que le comportement peut être placé dans de mauvais paquetages et casser la modularité du logiciel. Une bonne organisation des classes dans des paquetages identifiables facilite la compréhension, la maintenance, les tests et l'évolution des logiciels. Nous soutenons que les responsables manquent d'outils pour assurer la remodularisation logicielle. La maintenance des logiciels nécessite des approches qui aident à (i) la compréhension de la structure au niveau du paquetage et l'évaluation de sa qualité; (ii) l'identification des problèmes de modularité, et (iii) la prise de décisions pour le changement. Dans cette thèse nous proposons ECOO, une approche qui aide la remodularisation. Elle concerne les trois domaines de recherche suivants: (i) Comprendre les problèmes de dépendance entre paquetages. Nous proposons des visualisations mettant en évidence les dépendances cycliques au niveau des paquetages; (ii) Proposer des dépendances qui devraient être changées. L'approche propose des dépendances à changer pour rendre le système plus modulaire; (iii) Analyser l'impact des changements. L'approche propose une analyse d'impact du changement pour essayer les modifications avant de les appliquer sur le système réel. L'approche présentée dans cette thèse a été validée qualitativement et les résultats ont été pris en compte dans la réingénierie des systèmes analysés. Les résultats obtenus démontrent l'utilité de notre approche.
