The semantic approach to data storage, management and extraction is a promising concept that has constantly been gaining importance during the past years. However, the visualization of semantic data systems as well as the functionalities of their interfaces still contain some obstacles for both, the interaction designer and the interacting user. In order to accommodate to those obstacles, the interaction designer has to come up with an intuitive and efficient user interface design, introducing inexperienced users to data representation and extraction in a semantic environment. The intention of this work is to provide an overview over the disciplines of Human Computer Interaction and Interaction Design, with the intention to mediate the essential human-based and technical processes influencing the design of interaction, with a focus on the organisation and representation of unstructured, semantically rich data.
