Cengiz Acartürk completed his Ph.D. study in February, 2010. The project has been conducted within the framework of the research project Interaction of Representational Modalities in Communication, supervised by Prof. Dr. Christopher Habel, in Knowledge and Language Processing Group (WSV), Department of Informatics, University of Hamburg. Cengiz was a member of CINACS International Research Training Group between July, 2006 and July, 2009.

The dissertation can be downloaded as a pdf file from this link.

The title and the abstract of the dissertation, as well as a list of published and presented studies are presented below.

Multimodal Comprehension of Graph-Text Constellations: An Information Processing Perspective


Documents containing information in different representational modalities (e.g., text, pictorial and diagrammatic illustrations, graphs) are widely used in personal and professional settings of daily life, both in printed media and in human-computer interaction environments, such as WWW. In particular, graph-text constellations are one of those cognitive means by which we accomplish high-level problem solving and communication tasks. This dissertation performs a systematic, scientific investigation of multimodal comprehension of graph-text constellations by humans—as natural cognitive systems—for providing empirical basis and scientific models for the design and development of artificial cognitive systems that have the capacity to support users during their design and production of graph-text constellations. First, an overview of the existing approaches in graph comprehension and language comprehension is presented. Second, a theoretical framework is developed by extending the reach of the existing approaches to embody comprehension of graphical and linguistic entities under the framework of the common conceptual basis for multimodal comprehension. Third, various aspects of the interaction between language comprehension and graph comprehension are empirically investigated by conducting experiments with human participants. The empirical investigations reveal how users integrate the information contributed by the representations in different modalities, how the changes in one modality lead to substantial influences in comprehension of the entities in the other modality, and how inappropriate design of graphs and graph-text combinations give rise to difficulties during the course of multimodal comprehension. Based on the analysis of those difficulties in comprehension from the perspective of HCI, this dissertation lays the foundations for appropriate design of graph-text constellations and for the development of software tools that would provide users with support for appropriate design during their course of designing and producing graph-text constellations.
