Text Visualisation Tool for Exploring Digitised Historical Documents

This paper describes a prototype timeline tool designed for humanities researchers exploring digitised historical documents.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

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.

From Paper to Pixels : Evaluating the Usability of Digitised Books online

Research problem: Digital libraries have invested significant resources digitising and providing access to an increasing number of books. The various approaches taken to visualise digitised books online, has potential to effect the usability and usefulness of the book to the user. Previous usability studies focus on the digital library as a whole, this study narrows the focus to the digitised book. The intention being to identify usability issues and investigate the effects a visualisation approach may have on users. Methodology: An anonymous survey was conducted, employing the Interaction Triptych Framework (ITF) to frame the relationships between the user and digitised books. Two examples of digitised books from the New Zealand Electronic Text Collection and the Internet Archive were used. Participants from library, archives and history fields, as well as general users, were invited to participate. Results: 132 participants began the survey, with 86 participants completing all of the required parts. Results suggest a slightly positive attitude towards the usability and usefulness of the examples, with Open Library rated higher for usability and both examples rated similarly for usefulness. Participant comments suggest many users appreciate features analogous to physical books, with regard to aesthetics, learnability and navigation, while for ease of use and reading, rich text appeared to be preferred over digital image based visualisation. Implications: Digital Libraries need to continually strive to improve the usability and usefulness of digitised books to satisfy their users, further research is suggested creating prototypes and conducting user testing to gain a deeper understanding of the relationship between users and digitised books online

Digital Approaches to Historical Archaeology:Exploring the Geographies of 16th Century New Spain

The humanities have always been concerned with ideas of space, place and time. However, in the past few years, and with the emergence of Digital Humanities and Computational Archaeology, researchers have started to apply an array of computational methods and geographical analysis tools in order to understand the role that space plays in the historical processes of human societies. As a result, historians and archaeologists, together with computer scientists, are currently developing digital approaches that can be used to address questions and solve problems regarding the geographies contained in documentary sources such as texts and historical maps. Digging into Early Colonial Mexico is an interdisciplinary project that applies a Data Science/Big Data approach to historical archaeology, focusing on the analysis of one of the most important historical sources of the 16th century in Latin America, called the Geographic Reports of New Spain. The purpose of this paper is to: a) describe the nature of the historical corpus, b) introduce the methodologies and preliminary results produced so far by the project, and c) explain some of the theoretical and technical challenges faced throughout the development of the methods and techniques that supported the analysis of the historical corpus

Extending defoe for the efficient analysis of historical texts at scale

Funding: This work was partly funded by the Data-Driven Innovation Programme as part of the Edinburgh and South East Scotland City Region Deal, by the University of Edinburgh, and by Google Cloud Platform research credits program.This paper presents the new facilities provided in defoe, a parallel toolbox for querying a wealth of digitised newspapers and books at scale. defoe has been extended to work with further Natural Language Processing () tools such as the Edinburgh Geoparser, to store the preprocessed text in several storage facilities and to support different types of queries and analyses. We have also extended the collection of XML schemas supported by defoe, increasing the versatility of the tool for the analysis of digital historical textual data at scale. Finally, we have conducted several studies in which we worked with humanities and social science researchers who posed complex and interested questions to large-scale digital collections. Results shows that defoe allows researchers to conduct their studies and obtain results faster, while all the large-scale text mining complexity is automatically handled by defoe.Postprin
