Inferring information about correspondences between data sources for dataspaces

Guo, Chenjuan January 2011 (has links)
Traditional data integration offers high quality services for managing and querying interrelated but heterogeneous data sources but at a high cost. This is because a significant amount of manual effort is required to help specify precise relationships between the data sources in order to set up a data integration system. The recent proposed vision of dataspaces aims to reduce the upfront effort required to set up the system. A possible solution to approaching this aim is to infer schematic correspondences between the data sources, thus enabling the development of automated means for bootstrapping dataspaces. In this thesis, we discuss a two-step research programme to automatically infer schematic correspondences between data sources. In the first step, we investigate the effectiveness of existing schema matching approaches for inferring schematic correspondences and contribute a benchmark, called MatchBench, to achieve this aim. In the second step, we contribute an evolutionary search method to identify the set of entity-level relationships (ELRs) between data sources that qualify as entity-level schematic correspondences. Specifically, we model the requirements using a vector space model. For each resulting ELR we further identify a set of attribute-level relationships (ALRs) that qualify as attribute-level schematic correspondences. We demonstrate the effectiveness of the contributed inference technique using both MatchBench scenarios and real world scenarios.

An investigation of cognitive processes in chronic pain

Edwards, Lindsey C. January 1992 (has links)
This thesis examines information-processing in chronic pain. "Schematic" processing is investigated selective memory for pain-related information is explored in depressed and non-depressed chronic pain patients, depressed non pain-patients and controls. A memory bias for sensory adjectives is found in the non depressed chronic pain group, while a tendency to over-recall both sensory and affective compared to neutral information is found in the depressed chronic pain group. No memory bias is observed in an acute pain group, and the implications of this are discussed. A possible cognitive avoidance mechanism is identified in depression. A questionnaire assessing beliefs about pain ("conceptual" processing) is developed and validated, and shown to differentiate between chronic pain patients and controls. The impact of two interventions for chronic pain (surgery and cognitive-behavioural management) on schematic and conceptual processing is investigated prospectively. In general the endorsement of organic beliefs decreases while the emphasis on psychological beliefs increases post-intervention. Evidence is found to suggest that surgery, but not cognitive-behavioural treatment, reverses pain-related memory biases. This is discussed in relation to changes in pain intensity. Evidence is provided to suggest that beliefs are causally related to several pain-related measures including anxiety, depression, health locus of control, cognitive coping strategies and activity levels. A word completion paradigm is employed to explore further the role of schematic processing in chronic pain, and finally, a lexical decision task is used to assess the role of word frequency effects in information-processing in chronic pain. These results suggest that memory biases in chronic pain cannot be explained by frequency effects, hence addressing the validity of the memory biases described earlier in the thesis.

The manipulation of schematic correspondences with the quantification of uncertainty in dataspaces

Mao, Lu January 2013 (has links)
Dataspaces aim to remove upfront cost in the generation of the schema mappings that reconcile schematic heterogeneities, and to incrementally improve the generated mappings based on user feedback. The reconciliation of schematic heterogeneities is a crucial step for translating queries between a mediating schema and data sources. The generation of schema mappings depends on the elicitation of conceptually equivalent schema constructs and information on schematic heterogeneities. Furthermore, many dataspace operations manipulate associations between schemas, for example for generating a global schema to mediate user queries. With a view to minimizing upfront costs associated with understanding the relationships between schemas, many schema matching algorithms and tools have been developed for postulating equivalent schema constructs. However, they derive simple associations between schema constructs, and do not provide rich information on schematic heterogeneities. Without manual refinement, the elicitation of conceptually equivalent schema constructs and schematic heterogeneities may create uncertainties that must be managed.The schematic correspondences captures a wide range of one-to-one and many-to-many schematic heterogeneities. This thesis investigates the use of schematic correspondences as a central component in a dataspace management system. To support query evaluation in a dataspace in which relationships between schemas are represented using schematic correspondences, we propose a mechanism for automatically generating schema mappings from the schematic correspondences. We then characterise model management operators, which can underpin the bootstraping and maintenance of dataspaces, over schematic correspondences. To support the management of uncertainty in dataspaces, we propose techniques for quantifying uncertainty in the equivalence of schema constructs from evidence in the form of similarity scores and user feedback, and provide a flexible framework for incrementally updating the uncertainties in the light of new evidence.

Esquematismo da produção industrial e formação do indivíduo / Schematism industrial production and formation of the individual

Silva, Cesar Augusto Alves da 11 April 2016 (has links)
Esta tese tem como objetivo analisar a possibilidade de formação do indivíduo na sociedade industrial com base naquilo que se configurou como uma determinação importante, a saber, a produção em série que, para se realizar, demanda um esquema produtivo previamente estabelecido, um planejamento rigorosamente calculado, racionalmente construído de acordo com uma razão que expressa os interesses lucrativos do modo de produção capitalista. Objetivamos discutir o modo de produção capitalista industrial que se torna ideologia de si mesmo, como uma metafísica que se torna real por meio dessa produção. Ação real produtiva e esquema metafísico se autodeterminam mediados, ou determinados, pelo lucro. É um sistema que traz em si um modelo de racionalidade técnica e tecnológica que se tornam meio da imposição do esquematismo da produção sobre os indivíduos e em direta relação de correspondência à pseudoformação causadora do obscurecimento da subjetividade. Investiga-se a esquematização que a indústria cultural realiza na produção cultural. Tal esquematização atua já no campo da produção da cultura, determinando minuciosamente a elaboração dos objetos culturais. Analisam-se as condições de possibilidade da individualidade construir-se ou não no período contemporâneo. A infantilização e a obnubilação do desenvolvimento humano aparecem como resultado do processo do modo de produção capitalista industrial. O eu é derrotado antes mesmo de constituir-se, porque o diferente nunca é produzido em série. Conclui-se, então, que, no modo de produção capitalista industrial, os obstáculos para a formação do indivíduo e sua pseudoformação socializada não estão apenas no consumo dos produtos culturais mercantilizados. Tais limites já se originam concretamente na produção por meio do esquematismo alienado dos homens e imposto a eles / This thesis aims to analyze the possibility of formation of the individual in industrial society from what was configured as an important determination, namely the production series, to take place, demand a previously productive scheme, a carefully calculated plan rationally constructed according to a ratio expressing the profit interests of the capitalist mode of production. This paper discusses the industrial capitalist mode of production that becomes ideology of himself as a \"metaphysical\" that becomes real through this production. Productive real action and \"metaphysical\" consider themselves scheme mediated or determined by profit. It is a system which brings a technical and technological rationality model that make it through the schematic of the levy production on individuals and in direct relation matching the pseudoformação causing the subjectivity obscuration. The layout is investigated that the culture industry performs in cultural production. Such a layout is already active in the field of crop production, carefully determining the development of cultural objects. They analyze the conditions of possibility of individuality build up or not in the contemporary period. The infantilization and numbness of the human development process appear as a result of the industrial capitalist mode of production. The ego is defeated before even be created, because the other is never produced in series. It follows, then, that the industrial capitalist mode of production, the obstacles to the formation of the individual and his socialized pseudoformation are not only the consumption of commodified cultural products. These limits already originate specifically in production through the schematic alienated men and imposed on them

Form and freedom : the marriage of musical systems and intuition

Gotham, Nicholas January 2013 (has links)
This thesis includes an Introduction, which explains some of the ideas and procedures involved in a series of compositions I produced during the period from October, 2008 through November, 2011, a discussion of the works themselves individually and in roughly the same chronological order in which they were composed, and a summary of Conclusions which may be drawn. Included as an Appendix are texts for reference while listening to the vocal works. Complete scores of the works with representative recordings make up the main body of the thesis, except in the case of the solo piano suite Equilibria, where the score is included but the work remained unrecorded at the time of submission. Ideas discussed include some which unite or distinguish the processes of musical improvisation with/from more methodical modes of composition. Also the theme of musical collaboration is considered in contrast to the notion of the composer who works – or appears to work – in isolation. Research into traditions of music is regarded as important to compositional practice overall. Among the Conclusions is that my own orientation to these ideas places me in the category of post-minimalist composers. Throughout this discussion I have involved commentary from other relevant and important thinkers, critics and composers.

Automatic derivation of schematic maps from large scale digital geographic datasets for mobile GIS

Anand, Suchith January 2006 (has links)
"Mapping is a way of visualizing parts of the world and maps are largely diagrammatic and two dimensional. There is usually a one-to-one correspondence between places in the world and places on the map, but while there are limitless aspects to the world, the cartographer can only select a few to map" Daniel Dorling, 1996 Map generalization is the process by which small scale maps are derived from large scale maps. This requires the application of operations such as simplification, selection, displacement and amalgamation to map features subsequent to scale reduction. The work is concerned with the problem of effective rendering of large scale datasets on small display devices by developing appropriate map generalization techniques for generating schematic maps. With the advent of high-end miniature technology and large scale digital geographic data products it is essential to devise proper methodologies and techniques for the automated generation of schematic maps specifically tailored for mobile GIS applications. Schematic maps are diagrammatic representation based on linear abstractions of networks. Transportation networks are the key candidates for applying schematization to help ease the interpretation of information by the process of cartographic abstraction. This study looks at how simulated annealing optimisation technique can be successfully applied for automated generation of schematic maps from large scale digital geographic datasets tailored specifically for mobile GIS applications. The software developed makes use of a simulated annealing based schematic map generator algorithm to generate route maps from OSCAR® dataset corresponding to a series of user defined start and end points. The generated schematic route maps are displayed and tested on mobile handheld devices shows promising results for mobile GIS applications. This work concentrates on the automatic generation of schematic maps, which, in the context of mobile mapping, are seen as being a particularly useful means of displaying routes for way finding type and utility network applications.

What basic emotions are experienced in bipolar disorder and how are they are regulated

Carolan, Louise January 2009 (has links)
Introduction: There remains a lack of theoretical models which can adequately account for the key features of bipolar disorders (Power, 2005). Objectives: Firstly, to test the predictions made by the SPAARS model that mania is predominantly characterised by the coupling of happiness with anger, while depression (unipolar and bipolar) primarily comprises of a coupling between sadness and disgust. Secondly, to investigate and compare the coping strategies employed to regulate positive and negative emotion between bipolar, unipolar and control groups. Design: A cross sectional design was employed to examine the differences within and between the bipolar, unipolar and control groups in the emotions experienced and the strategies used to regulate emotion. Data were analysed using ANOVAs. Method: Psychiatric diagnoses in the clinical groups were confirmed using the SCID. Current mood state was measured using the BDI-II, STAI and the MAS. The Basic Emotion Scale was used to explore the emotional profiles and the Regulation of Emotion Questionnaire was used to measure coping strategies. Results: The results confirmed the predictions made by the SPAARS model about the emotions in mania and depression. Elevated levels of disgust were also found in the bipolar group generally. The clinical groups used internal dysfunctional strategies more often than the controls for negative emotion. The bipolar group used external dysfunctional strategies more frequently than the controls for positive emotion. Conclusion: The results support the predictions made by the SPAARS model and suggest that disgust plays a key role in bipolar disorder. Strengths and limitations are discussed and suggestions for future research are explored.

Vers une théorie de l'anticipation du sens : Principes d'analyse structurale / Towards a theory of the meaning anticipation : Structural analysis principles

Decobert, Bernard 24 October 2014 (has links)
Ce travail de thèse interroge la structure fondamentale du langage. Il s’inscrit dans la tradition greimassienne en ce sens qu’elle assume son affiliation avec les théories de Hjelmslev, Jakobson, Lévi-Strauss et Propp. Mais au-delà, il cherche ce que ces théories ont en commun et qu’elles n’avaient peut-être pas encore suffisamment abordé, notamment certaines relations avec la théorie thomienne/petitotienne. Nous postulons dans cette étude que le discours subit la contrainte d’un ordre sémantico-syntaxique sous-jacent et structurant. Plus précisément, nous postulons que le discours tend à s’organiser à partir, et/ou autour, d’une même chaîne sous-jacente, hiérarchique, contraignante, non aléatoire, transphrastique et restreinte de catégories sémantiques fondamentales. Nous nous inscrivons de fait dans le champ morphodynamique. A partir d’une double approche sémasiologique et distributionnelle, puis par des méthodes statistiques et mathématiques, nous montrons que certains sèmes, assimilables à des universaux et aux propriétés topologiques sous-jacentes, s’incrémentent naturellement dans le corps des énoncés. Ainsi, ce ne sont plus principalement des sèmes isolés que nous étudions mais des séries, des chaînes, des agencements syntagmatiques qui débouchent sur une forme de « proto-raisonnement » associant des sèmes. Enfin, nous montrons par l’expérimentation qu’il existe vraisemblablement aussi d’autres régularités à l’intérieur de cette structure continue ; régularités qui permettent de conforter l’hypothèse d’un principe autosimilaire entre structure profonde et structure superficielle. Notre thèse s’attache en principal à décrire, et à justifier l’existence d’un tel phénomène structural. / This thesis questions the fundamental structure of language. It belongs to the Greimas tradition in the sense that it assumes its affiliation with the theories of Hjelmslev, Jakobson , Levi-Strauss, and Propp. This work tries to go beyond by defining connections with Thom and Petitot theory. In this study, we postulate that discourse is constrained by an underlying semantic and syntactic structural order. More specifically, our assumption is that the discourse tends to be organized from and/or around a same underlying chain, involving non-random hierarchy, going beyond the sentences and being constrained to semantic fundamental categories. Our analysis is also included in a morphodynamic framework.From a double semasiologic and distributional approach, and from statistical and mathematical methods, we show that various semes, linked to universals and topological underlying properties, are naturally incremented in the discourse.As a consequence, what we are studying is not a collection of isolated semes but series, chains, syntagmatic arrangements that yield to a form of "proto-reasoning" associating semes. Finally, we show by experimentation, as there are likely other regularity patterns within the continuous structure. These regularities allow us to support the hypothesis of a self-similar principle between deep structure and surface structure. This thesis work is mainly focused on the description and the justification of the existence of such a structural phenomenon.
