Timeline design for visualising cultural heritage data

This thesis is concerned with the design of data visualisations of digitised museum, archive and library collections, in timelines. As cultural institutions digitise their collections—converting texts, objects, and artworks to electronic records—the volume of cultural data available grows. There is a growing perception, though, that we need to get more out of this data. Merely digitising does not automatically make collections accessible, discoverable and comprehensible, and standard interfaces do not necessarily support the types of interactions users wish to make. Data visualisations—this thesis focuses on interactive visual representations of data created with software—allow us to see an overview of, observe patterns in, and showcase the richness of, digitised collections. Visualisation can support analysis, exploration and presentation of collections for different audiences: research, collection administration, and the general public. The focus here is on visualising cultural data by time: a fundamental dimension for making sense of historical data, but also one with unique strangeness. Through cataloguing, cultural institutions define the meaning and value of items in their collections and the structure within which to make sense of them. By visualising threads in cataloguing data through time, can historical narratives be made visible? And is the data alone enough to tell the stories that people wish to tell? The intended audience for this research is cultural heritage institutions. This work sits at the crossroads between design, cultural heritage (particularly museology), and computing—drawing on the fields of digital humanities, information visualisation and human computer-interaction which also live in these overlapping spaces. This PhD adds clarity around the question of what cultural visualisation is (and can be) for, and highlights issues in the visualisation of qualitative or nominal data. The first chapter lays out the background, characterising cultural data and its visualisation. Chapter two walks through examples of existing cultural timeline visualisations, from the most handcrafted displays to automated approaches. At this point, the research agenda and methodology are set out. The next five chapters document a portfolio of visualisation projects, designing and building novel prototype timeline visualisations with data from the Wellcome Library and Victoria & Albert Museum, London, Cooper Hewitt Smithsonian Design Museum, New York City, and the Nordic Museum, Stockholm. In the process, a range of issues are identified for further discussion. The final chapters reflect on these projects, arguing that automated timeline visualisation can be a productive way to explore and present historical narratives in collection data, but a range of factors govern what is possible and useful. Trust in cultural data visualisation is also discussed. This research argues that visualising cultural data can add value to the data both for users and for data-holding institutions. However, that value is likely to be best achieved by customising a visualisation design to the dataset, audience and use case.

Design as Externalization: enabling research

The article is concerned with a central contribution of designing to information visualization in the digital humanities. The activity is characterized as one of externalization, instantiation in visible or tangible form of ideas that might otherwise be internal to the minds of the designer and other participants. A spectrum of different interpretations of this process in the existing literature is discussed, focusing on early attempts to theorize designing as a means of creating new knowledge, and especially the ways in which that new knowledge contributes to defining or redefining the question or problem to be addressed. The arguments are illustrated with recent practical examples from the authors’ own work in designing with a range of cultural organizations, museums and archives. The article concludes with reflections on how projects may best benefit from this work of design, empowering the designer as a co-researcher, alongside the historian, curator or other humanities scholar

Text Visualisation Tool for Exploring Digitised Historical Documents

This paper describes a prototype timeline tool designed for humanities researchers exploring digitised historical documents. The tool visualises keyword instances in context mapped by date, and can be used to explore commentary around themes through time. Through designing the tool and evaluating it with humanities scholars, the role of the designer in the digital humanities is explored. Interview evaluation with historians provides evidence for the tool's capacity to support historical research, but also raises design issues by pointing to the value of simple, minimal design in this domain for interpretability

Using Data Visualisation to tell Stories about Collections

The paper explores visualisation of “big data” from digitised museum collections and archives, focusing on the relationship between data, visualisation and narrative. A contrast is presented between visualisations that show “just the data” and those that present the information in such a way as to tell a story using visual rhetorical devices; such devices have historically included trees, streams, chains, geometric shapes and other forms. The contrast is explored through historical examples and a survey of current practice. A discussion centred on visualising datasets from the British Library, Science Museum and Wellcome Library is used to outline key research questions

Can I believe what I see? Data visualisation and trust in the humanities

Questions of trust are increasingly important in relation to data and its use. The authors focus on humanities data and its visualisation, through analysis of their own recent projects with museums, archives and libraries internationally. Their account connects the specifics of hands-on digital humanities work to larger epistemological questions. They discuss the sources of potential mistrust, and examine how different expectations and assumptions emerge depending on the use and user of the data; they offer a simple schema through which the implications may be traced. It is argued that vital issues of trust can be engaged with through design, which, rather than being conceived as a cosmetic finish, is seen as contributing insights and questions that affect the whole process. The article concludes with recommendations intended to be useful in both theory and practice

Maps of a Nation? : The Digitized Ordnance Survey for New Historical Research

Although the Ordnance Survey has itself been the subject of historical research, scholars have not systematically used its maps as primary sources of information. This is partly for disciplinary reasons and partly for the technical reason that high-quality maps have not until recently been available digitally, geo-referenced, and in color. A final, and crucial, addition has been the creation of item-level metadata which allows map collections to become corpora which can for the first time be interrogated en masse as source material. By applying new Computer Vision methods leveraging machine learning, we outline a research pipeline for working with thousands (rather than a handful) of maps at once, which enables new forms of historical inquiry based on spatial analysis. Our ‘patchwork method’ draws on the longstanding desire to adopt an overall or ‘complete’ view of a territory, and in so doing highlights certain parallels between the situation faced by today’s users of digitized maps, and a similar inflexion point faced by their predecessors in the nineteenth century, as the project to map the nation approached a form of completion

Hunting for Treasure: Living with Machines and the British Library Newspaper Collection

This chapter discusses the open access digitisation programme undertaken by Living with Machines, exploring the range of constraints that inform digitisation strategies and selection priorities. Because the landscape of digitised newspaper collections is so complex, and research and digitisation processes operate on different timelines, we have focused on opportunities to make digitisation choices both transparent and pragmatic. Working towards solutions that reflect collaborations between library staff and scholars, we introduce: a) Press Picker, our custom visualisation tool designed to support decision making about digitisation; and b) the Environmental Scan, a process of automatic metadata generation from the Newspaper Press Directories, a contemporaneous record of British newspapers
