by

│By Sarah L. Ketchley, Sr. Digital Humanities Specialist│

Gale Digital Scholar Lab has introduced a new visualisation feature in the Sentiment Analysis tool: Sentiment by Timeframe. This enables researchers to bring additional depth to sentiment analysis for historical texts. This tool is part of an ongoing effort to expand the capabilities of the Lab’s six digital humanities tools and is designed to support researchers in analysing, interpreting, and visualising data across various historical documents.

Re-imagining Assignments in the DH Classroom II: Timelines, Digital Exhibits, and Maps

by

│By Sarah L. Ketchley, Senior Digital Humanities Specialist│

This is a follow-up blog post to last month’s overview of working with Storymaps in the DH classroom.  We will consider a few more ways to engage students in the creative and intellectually rigorous process of building Digital Humanities projects, conducting analyses, and demonstrating the outcomes of a quarter or semester’s-worth of work. Developing timelines, exhibits and maps involves making use of Gale Digital Scholar Lab’s export functionality, which includes the ability to download:

  • The OCR text output of up to 5,000 documents in any given content set.
  • The full metadata of a content set, up to 10,000 documents.
  • Individual document images.
  • Analysis visualisations in multiple image formats.
  • Analysis raw data in CSV or JSON formats.
  • Documentation and records completed using the Notebook feature, in multiple text formats.

This exported information can then be used as the underlying data for a variety of interactive and public-facing student assignments.

Understanding Recent Enhancements to Sentiment Analysis in Gale Digital Scholar Lab

by

│By Sarah L. Ketchley, Senior Digital Humanities Specialist│

Sentiment Analysis can be described as an exploratory form of analysis that reveals trends or patterns in positive, negative or neutral sentiment of a collected set of documents (a ‘Content Set’). This type of analysis can identify avenues for further research or investigation at both a macro (Content Set) and micro (document) level.1 Sentiment Analysis is one of the six analysis tools available in Gale Digital Scholar Lab where it was recently updated to include an expanded sentiment lexicon which offers opportunities to further refine analysis results. This blog post will discuss these enhancements and offer suggested pathways to work with Sentiment Analysis both in the classroom and for research.

Decolonising the Literary Curriculum: A Close Examination of Derek Walcott’s Omeros

by
Skyline of Cape Town, South Africa

|By James Carney, Senior Gale Ambassador at King’s College London|

Decolonisation refers to the process of attempting to undo the social, political, economic and cultural effects of imperialism on former colonies. Having just completed my undergraduate degree in English and Classical Literature at King’s College London, I have come to appreciate language and the written arts as potent mediums to contemplate, respond to and even resist the weight of colonial history.

My dissertation on Derek Walcott’s 1990 postmodern epic Omeros most thoroughly illustrated to me the nuances and creative potential of colonial victims to negotiate their present and historical standing in response to imperial agents. My exploration of this theme in Walcott’s work was particularly interesting as he ostensibly views colonisation as continuous, from nineteenth-century British and French empires to modern American capitalism, as the same force underlies both processes for the benefit of the typically white aristocracy, eclipsing native identity and homogenising Caribbean culture to artificiality.

Digging into Datasets in Gale Digital Scholar Lab

by

│By Sarah L. Ketchley, Senior Digital Humanities Specialist, Gale│

This dataset post is a follow-up to Working with Datasets, a Primer which discussed text datasets of primary sources and explored how to access and work with them in Gale Digital Scholar Lab. Here, we’ll look at the topics of the first eight datasets in the Lab in more detail, the types of documents included in each set, and consider how a user may work with them for analysis. Our next blog post will showcase classroom-based use of the Lab’s datasets as an introductory pathway into the field of digital humanities.

King Tut and Digital Humanities: A Pedagogical Case Study

by
Notes from our DH correspondent

│By Dr. Sarah L. Ketchley, Senior Digital Humanities Specialist│

The Department of Middle Eastern Languages and Cultures (MELC) at the University of Washington has a history of supporting work in Digital Humanities (DH) dating back to the 1980s. More recently, the department has offered regular introductory classes in DH, which I have taught since 2015. These are usually topical in nature, i.e., the data we work with in class is related to a particular Middle Eastern theme, often related to travel or archaeology in Egypt, which is my area of research interest. This Spring Quarter 2022, my undergraduates and graduates participated in a class called ‘Digital Media – King Tut and Digital Humanities’ to learn about the theory and processes of building DH projects based on data related to the discovery of Tutankhamun’s tomb in 1922, one hundred years ago.

Investigating the Evolution of Twenty-First Century Pop Culture Using Digital Humanities Techniques

by
Wall of Fame neon light

| By James Carney, Senior Gale Ambassador at King’s College London |

Since the new millennium’s infancy, popular culture and famous lifestyles have captivated the public to an ever greater extent. From the emergence of social media, to the escapism provided from global crises or even the marketability of celebrities in late stage capitalism, the facets of stardom’s grip are numerous. Pop culture has always been a platform for performance – be that of one’s talent, beauty, wealth or quirkiness – but in the twenty-first century, fan reaction and engagement have assumed a far more prominent role in these public theatrics. The political, social and artistic zeitgeist has become rooted not only in celebrity action, but in the increasingly deterministic public reaction too. Gale resources can be used to present the emergence of such a dichotomy through records of both output and interpretation, illuminating the dynamics of the twenty-first century’s evolved popular culture for both academic enquiry and entertainment.

Doing the Digital Laundry? Notes on Cleaning Unstructured Text Data

by
Notes from our DH Correspondent

│By Sarah L Ketchley, Senior Digital Humanities Specialist│

An integral part of the workflow of any digital humanities project involving text generated automatically by Optical Character Recognition (OCR) is the correction of so-called OCR errors. The process is also called ‘data cleaning’. This post will explore some of the considerations researchers should be aware of before starting to clean their data in Gale Digital Scholar Lab, using the built-in text cleaning tool. It will also offer additional resources for working with data in other formats outside of the Lab.

Creating an Export Workflow with Gale Digital Scholar Lab

by
Notes from our DH Correspondent

│By Sarah L. Ketchley, Senior Digital Humanities Specialist│

This digital project was prompted by the broad research question: how was archaeology reported in The Illustrated London News (ILN)? The ILN is a publication notable for its fine illustrations and contributions by some of the pre-eminent archaeologists of the day. Gale Primary Sources offers access to the entire run of the newspaper covering the period 1842-2003. This blog post describes a workflow for the preliminary investigation of the data: initial content set creation, cleaning, analysis, export and visualization. At the outset, the research questions were necessarily broad:

  • Which words were most prevalent in articles reporting on archaeological digs?
  • What themes or topics are most prevalent in the dataset?
  • What was the overall feeling about this type of reporting? Was it reported favourably?
  • Is it possible to identify which archaeologists were directly contributing to the publication and how many contributions they made?

Engaging in the practical process of curation and analysis offers opportunities to refine these questions, and almost inevitably suggests new avenues for future exploration.
