Diese Arbeit beschäftigt sich mit der Nutzung von Worteinbettungen in der automatischen Analyse von argumentativen Texten. Die Arbeit diskutiert wichtige Einstellungen des Einbettungsverfahren sowie diverse Anwendungsmethoden der eingebetteten Wortvektoren für drei Aufgaben der automatischen argumentativen Analyse: Textsegmentierung, Argumentativitäts-Klassifikation und Relationenfindung. Meine Experimente auf zwei Standard-Argumentationsdatensätzen zeigen die folgenden Haupterkenntnisse: Bei der Textsegmentierung konnten keine Verbesserungen erzielt werden, während in der Argumentativitäts-Klassifikation und der Relationenfindung sich kleine Erfolge gezeigt haben und weitere bestimmte Forschungsthesen bewahrheitet werden konnten. In der Diskussion wird darauf eingegangen, warum bei der einfachen Worteinbettung in der argumentativen Analyse sich kaum nutzbare Ergebnisse erzielen lassen konnten, diese sich aber in Zukunft durch erweiterte Worteinbettungsverfahren verbessern können.
This thesis suggests cooperation as a design paradigm for human-computer interaction. The basic idea is that the synergistic co-operation of interfaces through concurrent user activities enables increased interaction fluency and expressiveness. This applies to bimanual interaction and multi-finger input, e.g., touch typing, as well as the collaboration of multiple users. Cooperative user interfaces offer more interaction
flexibility and expressivity for single and multiple users.
Part I of this thesis analyzes the state of the art in user interface design. It explores limitations of common approaches and reveals the crucial role of cooperative action in several established user interfaces and research prototypes. A review of related research in psychology and human-computer interaction offers insights to the cognitive, behavioral, and ergonomic foundations of cooperative user interfaces. Moreover, this thesis suggests a broad applicability of generic cooperation patterns and contributes three high-level design principles.
Part II presents three experiments towards cooperative user interfaces in detail. A study on desktop-based 3D input devices, explores fundamental benefits of cooperative bimanual input and the impact of interface design on bimanual cooperative behavior. A novel interaction technique for multitouch devices is presented that follows the paradigm of cooperative user interfaces and demonstrates advantages over the status quo. Finally, this thesis introduces a fundamentally new display technology that provides up to six users with their individual perspectives of a shared 3D environment. The system creates new possibilities for the cooperative interaction of
multiple users.
Part III of this thesis builds on the research results described in Part II, in particular, the multi-user 3D display system. A series of case studies in the field of collaborative virtual reality provides exemplary evidence for the relevance and applicability of the suggested design principles.
In this paper we introduce LUCI, a Lightweight Urban Calculation Interchange system, designed to bring the advantages of calculation and content co-ordination system to small planning and design groups by the means of an open source middle-ware. The middle-ware focuses on problems typical to urban planning and therefore features a geo-data repository as well as a job runtime administration, to coordinate simulation models and its multiple views. The described system architecture is accompanied by two exemplary use cases, that have been used to test and further develop our concepts and implementations.
This work presents a concept of interactive machine learning in a human design process. An urban design problem is viewed as a multiple-criteria optimization problem. The outlined feature of an urban design problem is the dependence of a design goal on a context of the problem. We model the design goal as a randomized fitness measure that depends on the context. In terms of multiple-criteria decision analysis (MCDA), the defined measure corresponds to a subjective expected utility of a user. In the first stage of the proposed approach we let the algorithm explore a design space using clustering techniques. The second stage is an interactive design loop; the user makes a proposal, then the program optimizes it, gets the user’s feedback and returns back the control over the application interface.
