Treating cultural works as nodes and influences as directed edges, the visualization of these cultural networks can provide new insights into the rich interconnections of cultural development such as that seen in movie references. All findings reported in this article were made through a process that involved network scientists, a media theorist and a sociologist; the role that visualization can play in bridging scientific communities was central to this work. The visualizations were in fact the result of a process to bring researchers from different disciplines together. While traditionally physicists have used different methods than those used by media theorists or sociologists, physicists are increasingly asking questions similar to those asked by media theorists or sociologists as they study the dynamics in networks. Visualization can serve as a common language that brings fields together and identifies the differences between them but that also has its own idiosyncratic views.

Treating cultural works as nodes and influences as directed edges, the visualization of these cultural networks can provide new insights into the rich interconnections of cultural development. The graphics represent complex relationships of movie references by combining macro views summarizing 100 years of movie influences with micro views providing a close-up look at the embedding of individual movies. The macro view shows the rise of the self-referential character of postmodern cinema, while the micro level illustrates differences between individual movies, when they were referenced and by whom. The visualizations provide views that are closer to the real complexity of the relationships than aggregated views or rankings could do.

[i.e. 9 - 14 November] 2014, Paris, France N2 - We created a pixel map for multivariate data based on an analysis of the needs of network security engineers. Parameters of a log record are shown as pixels and these pixels are stacked to represent a record. This allows a broad view of a data set on one screen while staying very close to the raw data and to expose common and rare patterns of user behavior through the visualization itself (the "Carpet"). 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. Our expert evaluation indicates that this visualization helps to scan large parts of log files quickly and to define areas of interest for closer inspection.

BT - An experimental visualization of personal movement data N2 - Shifted Maps proposes a novel visualization method to generate personal geovisualizations of individual movement data. The resulting visual appearance can be characterized as a map network consisting of visited places and their connections. The visited places are shown as circular map extracts scaled according to the time spent there and the movements between the places are represented as edges between the places. A key feature of the Shifted Maps visualization is the possibility to explore the data in three different arrangements based on geo-spatial position, travel time, and frequency of movements. By combining map and network visualizations of movement data, it becomes possible to analyze and compare spatial and temporal topologies.

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.

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.

Queer archives face the challenge of documenting identities that are inherently characterized by embracing fluidity and ambiguity. Thus, queer identities are diametrically opposed to archival procedures of unambiguous classification. At the same time, queer activism relies partly on coherent identity categories in order to be able to act politically. We examine the pragmatic solutions that queer archives establish when dealing with tensions between those requirements. Our goal is to contribute to the ongoing discussions about the ethical dimensions of classification practices. Following the work of Geoffrey C. Bowker and Susan Leigh Star (1999) we use the concept of boundary objects as a central theoretical foundation of our research. This concept allows for tracing the negotiations and decision-making processes that influenced the creation of a specific classification system. Through conducting semi-structured interviews with staff members of queer archives in Germany we collected data about their efforts to archive the history of queer communities. Although there are initiatives developing metadata standards for queer identities, these standards are only used to a limited extent by the queer archives we examined. Rather, those archives established individual strategies for categorizing objects that are rooted in their specific history. We argue that classification systems and controlled vocabularies themselves can be understood as artifacts documenting the history of queer movements.

Ausgehend von dem Projekt Sharing Knowledge (2014-2020), das im Ethnologischen Museum (Staatliche Museen zu Berlin/ Stiftung Preußischer Kulturbesitz) stattfand, wird argumentiert, dass die Trägheit von Infrastrukturen und die Erforschung ihrer Funktionsweise - d.h. die Entschlüsselung der Meistererzählungen und Ausschlussmechanismen hinter musealen Wissenspraktiken - entscheidende Schlüssel darstellen zur Entwicklung von Werkzeugen und Taktiken, um eben diese Trägheit zu umgehen und zu untergraben. Während der erste Teil des Papiers dem Beispielprojekt kritische Aufmerksamkeit schenkt, schlägt der zweite Teil neue Methoden vor, um Infrastrukturen zu entwickeln, die Relationalität und Pluralität zulassen.

However, it is the often comprehensive and complex nature of collections that can make it difficult to grasp their distribution and extent across a variety of dimensions. After a brief introduction to the research area of collection visualizations, this paper presents a design study visualizing an aggregated collection from diverse cultural institutions in Germany. We detail our iterative design process leading to prototypical implementations of four stylistically and functionally coordinated visualizations, each one focusing on different facets of the collection.

The conventional display of museum objects in online interfaces tends to neglect the physical gestalt of the collection. For example, coins typically end up in tabular grids of thumbnail pages in online collections mimicking their rigid placement in storage drawers of a depot and glass cabinets in exhibitions. The overall aim behind this research was to devise visualizations that do justice to the material and semantic richness of an entire collection, while providing a casual mode of access that is inviting to people with no background in numismatics. To do this, we undertook an iterative design process, which involved a close collaboration with numismaticians and playful ideation with actual coins. Carefully negotiating expert knowledge and lay curiosity, the resulting visualization represents the collection’s dimensions using thousands of thumbnails as visual data points. The coins can be arranged into various layouts such as piles representing, for example, metal types, or streams visualizing the ebb and flow of coins over the centuries. In the interface, one can play with the coins in a manner that would be unthinkable in a physical exhibition and that has not been tried in a digital display. The article reports on the overall research and design process of this project, the resulting interface concept and prototype, and the feedback received during two evaluations.
