Parts of Speech and Sentiment Analysis tools have a new view that allows users to see how the words in their documents have been identified by the tools. This is done via marking up the OCR*. In Parts of Speech, the mark-up indicates how each word has been categorised (for example as a noun or adjective), and in the Sentiment Analysis tool, it shows the sentiment of scored words.

This new view improves the transparency of these tools, making it easier for users to understand how they’re working. It’s also easier to move between distant and close reading, and understand the context in which the identified words appear within each document.

This mark-up view already existed for Named Entity Recognition, but was the only view of the document the user could access. We have added a link to the original scan of the document within the tool, bringing it in line with all the other tools and ensuring that the user can easily access all of the information and context they might need about a document when conducting their research.

*OCR = This acronym is used to refer to a machine-readable text version of a document. It stands for Optical Character Recognition, which is the process by which machine-readable text is obtained from a photograph of a document.

Sentiment by Timeframe is the third visualization in the Sentiment Analysis tool, and offers the following options: Century, Decade, Year, Month. With this visualization, users can navigate from the century level down to the month level, going in and out of different time periods within a Content Set to explore the nuances of specific timeframes. This update was made in direct response to user requests for increased granularity within the Sentiment Analysis tool and allows users to do more with their data.

Please note, available Timeframes are based on the metadata available for the documents being analyzed – if none of your documents include a publication month, then the month option will not appear for that year.

Homepage redevelopments were made, giving users a cleaner and more intuitive experience, highlighting key features and research routes the user can take. Updates included:

• Adding a Search Bar – often the first thing a user looks for, to immediately get started!
• Four large buttons indicating routes to get started: Build, Clean, Analyze, My Research
• Gale Research Showcase carousel – a rotating display, encouraging users to explore the Showcase for more examples and inspiration!
• Learning Center banner, flagging this key source of 24/7 support, including highlighting areas of particular use, and some of the questions it can answer.

Sentiment Analysis tool migrated from using the 111 version of the AFINN lexicon, to the 165 version of the AFINN lexicon, which includes an additional 905 scored words/tokens.

Please note analysis runs made before the update are no longer directly replicable.

The open-source algorithms that power the following tools were updated:

• Named Entity Recognition and Parts of Speech both use spaCy, an open-source natural language processing library. Both tools were updated to using version 3.7.4 of spaCy.
• Document Clustering uses scikit-learn, which is a machine learning library. The Document Clustering tool was updated to using version 1.4.0 of scikit-learn.

Thanks to the updates to these two Python-based software libraries, users will notice improved performance when using the tools.

A number of accessibility and styling updates were made, including:

• Improving text colours and mark-up view for Named Entity Recognition
• Enabling the user to download either the top 100 or top 25 results for Ngrams
• Adding a Tooltip to better explain functionality for Sentiment Analysis.

The ability to zoom for the Sentiment Over Time visualization was also introduced, so the user can make the visualization larger and explore it in more detail.

Lastly, the Word Cloud visualization for Ngrams was overhauled by moving to Highcharts. This brought it in line with our other visualizations, reduced white space and improved the readability of the words themselves. The results of an analysis were unchanged.

In April 2024 we launched Gale Research Showcase, a free, open repository of student-authored digital scholarship. Designed to advance early career research, it showcases high-quality, peer-reviewed essays that demonstrate best practices in digital scholarship.

Students can use Gale Research Showcase to get inspiration and guidance on using Digital Humanities techniques in their own projects – and to get published!

Publishing in Gale Research Showcase is a great opportunity for early-career researchers to experience the Peer Review process, and get free feedback, support and suggestions from Gale’s DH experts on their DH project.

Gale Research Showcase is a great tool for faculty, librarians and educators to use when developing a DH curriculum, providing a hub of research examples to enhance instruction and engage and motivate students.

Released at the same time as Group Workspaces, the Group Notebook is a collaborative note-taking tool which allows students and researchers to communicate, ideate, and iterate on their projects together, helping to develop good research methodologies, as well as project management and report writing skills.

Significantly it allows students to create collaborative notes on content sets, clean configurations, and visualizations – from directly within those features, thus not disrupting their workflow. Users can also add images and links to their notes. The feature also records information such as the author of each note and date it was added, allowing group member contributions to be tracked.

The Group Notebook can also be used by educators to provide students with support materials, resources, and feedback to guide project-based learning.

Later updates included:

• A Sort feature, making it easier to navigate the Notebook.
• Additional Export options, allowing users to download notes as a CSV, Word or PDF file.
• Pan-Zoom functionality for images in the Notebook, allowing users to interact with notes more effectively.

Released at the same time as Group Notebooks, the Group Workspace feature was introduced to allow users to view other group members’ content, build content sets collaboratively, and share visualizations between group members.

This functionality helps students and researchers develop project management and collaboration skills. It also allows educators to oversee their class’s work by joining each group, meaning they can offer support when needed and keep projects on track.

Collaboration is a huge part of digital humanities work, and this update was in direct response to extensive user requests.

Later updates included:

• The ability to select avatars for each collaborator, and for the group itself.
• Replicating the Merge, Move and Duplicate Content Set functions in the Group Workspace, aligning it with the functionality of the Personal Workspace.

Collaborators must all be at the same institution, due to rights limitations.
