The purpose of the visualization is twofold: first to expose the implicit structure in subject headings as an overview of a library collection and second to present a visual web of keywords to invite exploration of books. Taking a tag cloud as a starting point, the visualization extends it to a networked tag cloud that respects the hierarchy that is implicit in subject headings. By allowing an information seeker to successively build a subject filter, while seeing the results at each step, we hope to improve the searcher's orientation in a comprehensive book collection.}, subject = {Informationstheorie}, language = {en} } @incollection{DoerkComberDadeRobertson, author = {D{\"o}rk, Marian and Comber, Rob and Dade-Robertson, Martyn}, title = {Monadic Exploration}, series = {CHI 2014 : one of a CHInd ; The 32nd Annual ACM Conference on Human Factors in Computing Systems, conference proceedings, Toronto, Canada, April 26 - May 1}, booktitle = {CHI 2014 : one of a CHInd ; The 32nd Annual ACM Conference on Human Factors in Computing Systems, conference proceedings, Toronto, Canada, April 26 - May 1}, publisher = {ACM}, address = {New York, NY}, isbn = {978-1-4503-2473-1}, doi = {10.1145/2556288.2557083}, pages = {1535 -- 1544}, abstract = {Monadic exploration is a new approach to interacting with relational information spaces that challenges the distinction between the whole and its parts. Building on the work of sociologists Gabriel Tarde and Bruno Latour we turn to the concept of the monad as a useful lens on online communities and collections that expands the possibility for creating meaning in their navigation. While existing interfaces tend to emphasize either the structure of the whole or details of a part, monadic exploration brings these opposing perspectives closer together in continuous movements between partially overlapping points of view. We present a visualization that reflects a given node's relative position within a network using radial displacements and visual folding. To investigate the potential of monadic exploration we report on an iterative design process of a web-based visualization of a highly cross-referenced book and its six-month deployment.}, subject = {Informationstheorie}, language = {en} } @incollection{LandstorferHerrmannStangeetal., author = {Landstorfer, Johannes and Herrmann, Ivo and Stange, Jan-Erik and D{\"o}rk, Marian and Wettach, Reto}, title = {Weaving a Carpet from Log Entries}, series = {2014 IEEE Conference on Visual Analytics Science and Technology (VAST) : 25 - 31 Oct.

Visualizations that immediately point to areas of suspicious activity without requiring extensive filtering, help network engineers investigating unknown computer security incidents. Most of them, however, have limited knowledge of advanced visualization techniques, while many designers and data scientists are unfamiliar with computer security topics. To bridge this gap, we developed visualizations together with engineers, following a co-creative process. We will show how we explored the scope of the engineers' tasks and how we jointly developed ideas and designs.

Projection techniques generally aim to make a high-dimensional information space visible in form of a planar layout. However, the meaning of the resulting data projections can be hard to grasp. It is seldom clear why elements are placed far apart or close together and the inevitable approximation errors of any projection technique are not exposed to the viewer. Previous research on dimensionality reduction focuses on the efficient generation of data projections, interactive customisation of the model, and comparison of different projection techniques. There has been only little research on how the visualization resulting from data projection is interacted with. We contribute the concept of probing as an integrated approach to interpreting the meaning and quality of visualizations and propose a set of interactive methods to examine dimensionality-reduced data as well as the projection itself. The methods let viewers see approximation errors, question the positioning of elements, compare them to each other, and visualize the influence of data dimensions on the projection space. We created a web-based system implementing these methods, and report on findings from an evaluation with data analysts using the prototype to examine multidimensional datasets.}, subject = {Informationswissenschaft}, language = {en} } @incollection{GlinkaMeierDoerk, author = {Glinka, Katrin and Meier, Sebastian and D{\"o}rk, Marian}, title = {Visualising the »Un-seen«}, series = {Kultur und Informatik - Cross Media}, booktitle = {Kultur und Informatik - Cross Media}, publisher = {Werner H{\"u}lsbusch}, address = {Gl{\"u}ckstadt}, isbn = {978-3-86488-082-7}, pages = {105 -- 117}, abstract = {In recent years, access to cultural heritage has been closely connected to digitisation.

We present related work, use cases, and concepts for visualisations and interfaces that invite the reconsideration of modes of categorisation, presentation and clustering.

To support such a casual form of engagement with text, we designed the WordWanderer system: a visualisation technique that extends tag clouds into a navigational interface for text. The tool supports the gradual movement between word 'context views', which represent the words that co-occur in the vicinity of the selected word, and word-'comparison views', which arrange words based on their association strengths between two selected words.

Challenging an institutionalized understanding of overview and detail as inherently opposed, the intention of this research is to develop a visualization method that accounts for the iconographic abundance of a collection and encourages its casual exploration. Expanding digitization efforts have led to a growing number of rich cultural heritage datasets that are successively being published online. At the same time scholars are exploring the potential of computational methods to expand the scale and scope of art history. In this context, data visualization is often equated with a distanced perspective diminishing the intricate and intriguing details of individual artifacts. In collaboration with a museum of applied and decorative arts, we have devised a novel interface concept for the exploration of image collections such as historical glass plate negatives. Inspired by photographic plates on a light table, the resulting Close-up Cloud translates the art historical method of close viewing into the digital by combining it with a dynamic representation of quantitative iconographic patterns across an entire image collection.}, subject = {Visualisierung}, language = {en} }
