    Applying quantitative and qualitative content and sentiment analysis, this study investigates the use of financial information by politicians in the Portuguese parliament, in a changing context. There is clear preference for Budgetary Information. A change in the political majority in Parliament and an improvement in the country’s economic and financial situation affect the intensity and intentions of using financial information by politicians – the use with positive sentiments of those government-related, to legitimize their policies, and with negative sentiments when they pass to the opposition, using it as ammunition or to divert attention from measures implemented when they were in power.info:eu-repo/semantics/publishedVersio

    Evaluating intuitive interactions using image schemas

    Get PDF
    Intuitive use is a desirable feature in interface design. In the last decade, researchers have made considerable progress in developing approaches for design for intuitive use. Most of the current approaches, however, have been limited to qualitative exploration, in the form of providing guidelines aimed to help designers to design products that are intuitively useable. This thesis focusses on developing a quantitative approach for evaluating intuitive interaction with the help of image schemas. An image schema is a recurring structure within the human cognitive system that establishes patterns of reasoning with the physical world. Researchers have found this concept to be very useful in capturing human interaction with products; it is also suitable for analysing product features. The approach developed in this thesis measures intuitive interaction based on the degree of match (known in this study as quantification, ‘Q’) between the designer’s intent and the users’ interaction both expressed through image schemas. The value of the proposed approach is in the provision of measurable outputs for evaluating intuitive interaction. The proposed approach is evaluated through an empirical study designed to test the validity of ‘Q’ as a measure of intuitive use expressed through task completion time, errors and cognitive effort. The results reveal that participants with high ‘Q’ value were significantly quicker, made fewer errors, and expended less cognitive effort while completing all subtasks with the three products used in the study. Secondly, the thesis addresses the limitation of other studies in the applicability of the methods used for extracting image schemas. Previous approaches have predominantly relied on the expertise of the researcher conducting the study in extracting the identified image schemas from the utterances of the users. This could introduce subjective bias, thereby reducing the reliability of the method for extracting image schemas. This study addressed this limitation by developing a systematic approach based on a novel algorithm for extracting image schemas from users’ utterances. This enhanced image schema extraction method is based on the use of two ontologies: a lexical ontology and a domainspecific ontology (image schema ontology). The domain-specific ontology was purpose-built for the needs of this study. The independent evaluation study conducted to evaluate the algorithm revealed a substantial strength with an overall k of 0.67 across the 3 products used in the study. Previous studies have predominantly focussed on the cognitive aspect of intuitive use. A limited amount of work has explored the affective aspect of intuition, and integrated it into the evaluation of intuitive use. This study addressed this limitation by developing a novel approach for assessing the affective aspect of the intuitive use of products. This novel approach incorporates the enhanced algorithm for extracting image schemas that was developed for this study. In addition, a sentiment analysis on the affective words linked to the image schemas employed in the task is used as part of the evaluation process. The proposed approach is evaluated through an empirical study based on the sentiments used in describing the image schemas employed for the interaction. The results show that the approach links the image schemas used for the completion of a task to the affective experiences of the users. This has potential to lead to significant improvements in design for intuitive use because it allows experiences to be linked directly to the specific image schemas employed in the design. Overall, the study contributes significantly to the knowledge in this field by validating a new quantitative approach for evaluating intuitive interactions with physical objects. The approaches developed in this study will enable designers to evaluate intuitive usage at different phases of the design process

    Fine-grained position analysis for political texts

    Full text link
    Meinungsanalyse auf politischen Textdaten hat im Bereich der Computerlinguistik in den letzten Jahren stets an Bedeutung gewonnen. Dabei werden politische Texte zumeist in voneinander diskrete Klassen unterteilt, wie zum Beispiel pro vs. contra oder links vs. rechts. In den Politikwissenschaften dagegen werden bei der Analyse von politischen Texten Positionen auf Skalen mit fließenden Werten abgebildet. Diese feingranulare Darstellung ist für die dort gegebenen Fragestellungen erforderlich. Das Feld der “quantitativen Analyse” - der automatisierten Analyse von Texten - die der traditionellen qualitativen Analyse gegenüber steht, hat erst kürzlich mehr Beachtung gefunden. Bisher werden Texte dabei zumeist lediglich durch Worthäufigkeiten dargestellt und ohne jegliche Struktur modelliert. Wir entwickeln in dieser Dissertation Ansätze basierend auf Methoden der Computerlinguistik und der Informatik, die gegeignet sind, politikwissenschaftliche Forschungsfragen zu untersuchen. Im Gegensatz zu bisherigen Arbeiten in der Computerlinguistik klassifizieren wir nicht diskrete Klassen von Meinungen, sondern projizieren feingranulare Positionen auf fließende Skalen. Darüber hinaus schreiben wir nicht Dokumenten ganzheitlich eine Position zu, sondern bestimmen die Meinungen zu den jeweiligen Themen, die in den Texten enthalten sind. Diese mehrdimensionale Meinungsanalyse ist nach unserem Kenntnisstand neu im Bereich der quantitativen Analyse. Was unsere Ansätze von anderen Methoden unterscheidet, sind insbesondere folgende zwei Eigenschaften: Zum Einen nutzen wir Wissen aus externen Quellen, das wir in die Verfahren einfließen lassen - beispielsweise integrieren wir die Beschreibungen von Ministerien des Bundestags als Definition von politischen Themenbereichen, mit welchen wir automatisch Themen in Parteiprogrammen erkennen. Zum Anderen reichern wir unsere Verfahren mit linguistischem Wissen über Textkomposition und Dialogstruktur an. Somit gelingt uns eine tiefere Modellierung der Textstruktur. Anhand der folgenden drei Fragestellungen aus dem Bereich der Politikwissenschaften untersuchen wir die Umsetzung der oben beschriebenen Methoden: 1. Multi-Dimensionale Positionsanalyse von Parteiprogrammen 2. Analyse von Themen und Positionen in der US-Präsidentschaftswahl 3. Bestimmen von Dove-Hawk-Positionen in Diskussionen der amerikanischen Zentralbank Wir zeigen, dass die vorgestellten Lösungen erfolreich feingranulare Positionen in den jeweiligen Daten erkennen und analysieren Möglichkeiten sowie Grenzen dieser zukunftsweisenden Verfahren
