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.

│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.

Digital Humanities and Data Mining: The Key to Efficient Seminar Preparation

Anyone that says to a humanities student ‘all you have to do is read a book and have an opinion’ is someone who’s never had to prepare for a seminar! Seminars are the foundation of my degree – they guide me to the crucial works in a given field, they give me the space to explore ideas, and sharpen my skills in argument and writing. But they can also be daunting, especially when you’re presented with the work of the finest minds in history and are expected to make sense of it; you know you’re intelligent, you know you can do this, but sometimes you just need a little push in the right direction…

*Enter Gale Digital Scholar Lab.*

Gale Digital Scholar Lab is designed to make data mining and primary research more efficient with a three-step process of build, clean, and analyse. Utilising some of these techniques, you can gain a solid idea of where the texts are going and what to look out for, something that is really helpful when you start reading the material more closely.

Notes from our DH Correspondent

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

Getting to grips with the scope and content of a digital primary source archive held by an institution’s library can be daunting, particularly if the archive consists of thousands of documents in a variety of formats. For an individual researcher, the task of sifting through vast quantities of data in the quest for material that is relevant for a particular research topic is something that can take years to accomplish. This blog post will explore some of the ways a researcher can use Gale Digital Scholar Lab in conjunction with Gale Primary Sources as a platform for exploratory analysis to gain insights into the topics and themes represented in a chosen archive.

Digital resources are vital to conducting academic research and teaching the next generation of scholars. As educators, teaching with technology can be daunting. In my previous blog posts PhDing in a Pandemic: The Impact of COVID-19 on Research and Teaching and Top 10 Tips for Teaching with Primary Sources, I’ve written about how you can help students get to grips with using a range of Gale Primary Sources including Eighteenth Century Collections Online, Burney Newspapers, and British Literary Manuscripts Online. But how do you help your students take the next step as digital humanists in a growing discipline? Teaching them how to use an innovative resource such as Gale Digital Scholar Lab is one way which you as an educator can help students develop their research skills and methodologies in a changing scholarly landscape.

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.

How The Gale Digital Scholar Lab Made Digital Humanities Less Daunting

│By Jagyoseni Mandal, Gale Ambassador at the University of Oxford│

The global pandemic that hit us last year and continues to affect numerous aspects of life has made research particularly difficult. I can say this from personal experience, as I have had to study for more than a term at my home in India, where I am stuck because of COVID, rather than studying at my university in Oxford. This situation risked affecting both my mental health and my studies; I felt I was running out of both time and resources for my research. But discovering the Gale Digital Scholar Lab has been a revelation, opening up a whole new area of potential research to me, and it is accessible entirely remotely. In this post I am going to share how the Gale Digital Scholar Lab made Digital Humanities accessible to me; how the various tools in helped me in my research and led me to discover more topics around my area of interest.

│By Chris Houghton, Head of Digital Scholarship, Gale International│

Studying extremist groups has, sadly, never been more relevant or more important. Can text mining and data analysis be used to enhance this study, and potentially make discoveries that could help with the ongoing fight against political extremism? In this blog, I provide some suggestions of how scholars might benefit from utilising these research methods, by showing what can be uncovered by combining Gale’s Political Extremism and Radicalism archive with the Gale Digital Scholar Lab.
