abstract: Computational tools in the digital humanities often either work on the macro-scale, enabling researchers to analyze huge amounts of data, or on the micro-scale, supporting scholars in the interpretation and analysis of individual documents. The proposed research system that was developed in the context of this dissertation ("Quadriga System") works to bridge these two extremes by offering tools to support close reading and interpretation of texts, while at the same time providing a means for collaboration and data collection that could lead to analyses based on big datasets. In the field of history of science, researchers usually use unstructured data such as texts or images. To computationally analyze such data, it first has to be transformed into a machine-understandable format. The Quadriga System is based on the idea to represent texts as graphs of contextualized triples (or quadruples). Those graphs (or networks) can then be mathematically analyzed and visualized. This dissertation describes two projects that use the Quadriga System for the analysis and exploration of texts and the creation of social networks. Furthermore, a model for digital humanities education is proposed that brings together students from the humanities and computer science in order to develop user-oriented, innovative tools, methods, and infrastructures. / Dissertation/Thesis / Doctoral Dissertation Biology 2014

Para isso, utilizaremos o conceito de matriz de Gram como critério de congruência, e a parametrização do espaço de con gurações será feito pelo invariante angular de Cartan e a razão-cruzada. Exempli caremos algumas situações geométricas. / The aim of this work is the construction of a moduli space for the con guration space ordered quadruples of points on the boundary of the complex hyperbolic space. For this use the concept of Gram matrix as a criterion of congruence, and parametrization the con guration space will be done by the Cartan invariant and cross-ratio. Will be exempli ed some geometric situations.
