Gute Ergebnisse aus „schlechten“ Textvorlagen
2016
Zusammenfassung Die OCR-Erkennung alter Frakturtexte ist noch immer Gegenstand verschiedener Forschungsarbeiten. Die bisher möglichen Ergebnisse erreichen die Ansprüche deutscher Drittmittelgeber in der Regel nicht. Der vorliegende Beitrag gewährt einen Einblick in ein Projekt, in dem Mainzer Wissenschaftler gemeinsam mit ihrer Universitätsbibliothek die Qualitätssicherung von OCR-Texten ausloten. Neue Forschungsansätze der Digital Humanities, wie das scalable reading, eröffnen Möglichkeiten, mit schlechten Scanergebnissen dennoch zu guten Forschungsergebnissen zu kommen.
Verstehen und Verständlichkeit von populärwissenschaftlichen Texten: Das Projekt PopSci – Understanding Science
2015
Die offentliche Akzeptanz und Wirkung natur- und technikwissenschaftlicher Forschung hangt grundlegend davon ab, ob sich die Ziele und Forschungsergebnisse an die Offentlichkeit vermitteln lassen. Doch die Inhalte aktueller Forschungsvorhaben sind fur ein Laienpublikum oft nur schwer zuganglich und verstandlich. Vor dem Hintergrund, die gesellschaftliche Diskussion natur- und technikwissenschaftlicher Forschung zu verbessern, untersuchen und bewerten wir im Projekt PopSci – Understanding Science einen wichtigen Sektor des popularwissenschaftlichen Diskurses in Deutschland empirisch. Hierfur identifizieren wir die linguistischen Merkmale deutscher popularwissenschaftlicher Texte durch korpus…
Validación y aplicación de un instrumento para el análisis de estereotipos de género en largometrajes de dibujos animados
2021
The process of design and validation of the content and structure of a tool for the analysis of gender stereotypes applicable to feature films, short films, and television series, both realistic and cartoonish, is presented. The model is called EG_5x4 and consists of five dimensions (corporal, attitudinal, social, affective-sexual, and audiovisual), being novel because of its distribution into four pairs of items per category. The methodological process began with the writing, based on previous instruments on gender stereotypes, of a draft of the items, which were distributed in dimensions and organized in pairs to be able to independently relate each statement to the male and/or female gen…
Sistema de indicadores culturales local (<i>Siclo</i>)
2012
Se ofrece una vision sintetica del proceso que ha dado lugar al Sistema de Indicadores Culturales Local ( Siclo ), una aplicacion orientada a mejorar el conocimiento sobre el estado de la accion cultural en el ambito de la administracion local. Pretende proporcionar informacion de apoyo que facilite la evaluacion de las politicas culturales locales. Se estructura en cinco areas tematicas y tres modulos. Actualmente solo se encuentra operativo el modulo basico que esta integrado por 46 indicadores.
Wahlkämpfe im Miniaturformat: Fernsehdebatten und ihre Wirkung am Beispiel des TV-Duells 2013 zwischen Angela Merkel und Peer Steinbrück
2014
AbstractFernsehduelle nach amerikanischem Format gibt es in Deutschland seit 2002, als sich Gerhard Schröder und Edmund Stoiber zu zwei Duellen trafen. In der Zwischenzeit sind solche Duelle zu einem festen Bestandteil von Wahlkämpfen geworden. In dem Beitrag gehen wir der Frage nach, warum die Ereignisse bei den beteiligten Akteuren, den übertragenden Medien, den zuschauenden Bürgerinnen und Bürgern, aber auch der Wissenschaft hohe Wertschätzung genießen. Am Beispiel der Bundestagswahl 2013 zeigen wir schließlich, wie sich diese „Wahlkämpfe im Miniaturformat“ erforschen lassen.
Developing human/AI interactions for chat-based customer services: lessons learned from the Norwegian government
2022
Advancements in human/AI interactions led to smartification of public services via the use of chatbots. Here, we present findings from a clinical inquiry research project in a key public service organisation in Norway. In this project, researchers and practitioners worked together to generate insights on the action possibilities offered to human service agents by chatbots and the potential for creating hybrid human/AI service teams. The project sensitised service agents to discover affordances based on their actual practices, rather than on the predefined use of chatbots. The different affordances identified can be useful for practitioners who design and deploy chatbot-based services. The a…
MODULAR KNOWLEDGE REPRESENTATION IN ADVISOR AGENTS FOR SITUATION AWARENESS
2011
A modular knowledge representation framework for conversational agents is presented. The approach has been realized to suit the situation awareness paradigm. The modularity of the framework makes possible the composition of specific modules that deal with particular features, simplifying both the chatbot design process and its smartness. As a proof of concepts we have developed a modular, situation awareness oriented, KB for a conversational agent, which plays the role of an advisor aimed at helping a user to be in charge of a virtual town, inspired to the SimCity series game. The agent makes an extensive use of semantic computing techniques and is able to perceive, comprehend and project c…
Motivation to engage in crowdsourcing: Towards the synthetic psychological–sociological model
2021
Abstract This article is aimed at analysis of user participation in web-based crowdsourcing projects in the digital humanities (DH) field, with a focus on what motivates these volunteers.1 The first aim of the article is a critical analysis of models of motivators for involvement offered to date. The analysis is based on a review of DH crowdsourcing literature, as a result of which there is an indication of shortcomings of the psychological data-driven approach that has dominated thus far. The second aim of the article is to offer a new model that synthesizes the psychological-motivation approach with a sociological one. Applying Pierre Bourdieu’s Theory of Capital, the motivation model cre…
Method to find the Minimum 1D Linear Gradient Model for Seismic Tomography
2016
The changes in the state of a geophysical medium before a strong earthquake can be found by studying of 3D seismic velocity images constructed for consecutive time windows. A preliminary step is to see changes with time in a minimum 1D model. In this paper we develop a method that finds the parameters of the minimum linear gradient model by applying a two-dimensional Taylor series of the observed data for the seismic ray and by performing least-square minimization for all seismic rays. This allows us to obtain the mean value of the discrete observed variable, close to zero value.
The shortest-path problem with resource constraints with -loop elimination and its application to the capacitated arc-routing problem
2014
Abstract In many branch-and-price algorithms, the column generation subproblem consists of computing feasible constrained paths. In the capacitated arc-routing problem (CARP), elementarity constraints concerning the edges to be serviced and additional constraints resulting from the branch-and-bound process together impose two types of loop-elimination constraints. To fulfill the former constraints, it is common practice to rely on a relaxation where loops are allowed. In a k-loop elimination approach all loops of length k and smaller are forbidden. Following Bode and Irnich (2012) for solving the CARP, branching on followers and non-followers is the only known approach to guarantee integer …
