Modeling is the activity of creating an abstract representation of a complex phenomenon, usually in a machine-readable way, possibly in an interactive way (i.e. it includes “simulation”). Models become machine-readable when modelling produces a schema that describes the elements and the structure of an object of inquiry in an explicit way. Modeling can also refer to the activity of transforming or manipulating a digital object in such a way as to make it compatible with a previously constructed model or schema. Mapping, for instance, is an example of a spatial model. Workflow design is included as part of Modeling, using an object such as Process.
FactGrid is both a database as well as a wiki. This project operated by the Gotha Research Centre and the data lab of the University of Erfurt. It utilizes MediaWiki and a Wikidata’s “wikibase” extension to collect data from historic research. With FactGrid you can create a knowledge graph, giving information in triple statements. This knowledge graph can be asked with SPARQL. All data provided by FactGrid holds a CC0-license.
TEI editions are among the most used tool by scholarly editors to produce digital editions in various literary fields. LIFT is a Python-based tool that allows to programmatically extract information from digital texts annotated in TEI by modelling persons, places, events and relations annotated in the form of a Knowledge Graph which reuses ontologies and controlled vocabularies from the Digital Humanities domain.
Based on the ancient name for the gate of the Athenian Acropolis, the PROPYLÄEN open up a variety of approaches to Johann Wolfgang von Goethe’s life, work, communication and actions.
Introduction: Folgert Karsdorp, Mike Kestemont and Allen Riddell ‘s interactive book, Humanities Data Analysis: Case Studies with Python had been written with the aim in mind to equip humanities students and scholars working with textual and tabular resources with practical, hands-on knowledge to better understand the potentials of data-rich, computer-assisted approaches that the Python framework offers to them and eventually to apply and integrate them to their own research projects.
The first part introduces a “Data carpentry”, a collection of essential techniques for gathering, cleaning, representing, and transforming textual and tabular data. This sets the stage for the second part that consists of 5 case studies (Statistics Essentials: WhoReads Novels? ; Introduction to Probability ; Narrating with Maps ; Stylometry and the Voice of Hildegard ; A Topic Model of United States Supreme Court Opinions, 1900–2000 ) showcasing how to draw meaningful insights from data using quantitative methods. Each chapter contains executable Python codes and ends with exercises ranging from easier drills to more creative and complex possibilities to adapt the apply and adopt the newly acquired knowledge to their own research problems.
The book exhibits best practices in how to make digital scholarship available in an open, sustainable ad digital-native manner, coming in different layers that are firmly interlinked with each other. Published with Princeton University Press in 2021, hardcopies are also available, but more importantly, the digital version is an Open Access Jupyter notebook that can be read in multiple environments and formats (.md and .pdf). The documentation, coda and data materials are available on Zenodo (https://zenodo.org/record/3560761#.Y3tCcn3MJD9). The authors also made sure to select and use packages which are mature and actively maintained.
Introduction: This short video teaser summarizes the main characteristics of PixPlot, a Python-based tool for clustering images and analyzing them from a numerical perspective as well as its pedagogical relevance as far as
machine learning is concerned.
The paper “Visual Patterns Discovery in Large Databases of Paintings”, presented at the Digital Humanities 2016 Conference held in Poland,
can be considered the foundational text for the development of the PixPlot Project at Yale University.

In this post, we reach back in time to showcase an older project and highlight its impact on data visualization in Digital Humanities as well as its good practices to make different layers of scholarship available for increased transparency and reusability.
Developed at Stanford with other research partners (‘Cultures of Knowledge’ at Oxford, the Groupe d’Alembert at CNRS, the KKCC-Circulation of Knowledge and Learned Practices in the 17th-century Dutch Republic, the DensityDesign ResearchLab), the ‘Mapping of the Republic of Letters Project’ aimed at digitizing and visualizing the intellectual community throughout the XVI and XVIII centuries known as ‘Republic of Letters’ (an overview of the concept can be found in Bots and Waquet, 1997), to get a better sense of the shape, size and associated intellectual network, its inherent complexities and boundaries.
Below we highlight the different, interrelated
layers of making project outputs available and reusable on the long term (way before FAIR data became a widespread policy imperative!): methodological reflections, interactive visualizations, the associated data and its data model schema. All of these layers are published in a trusted repository and are interlinked with each other via their Persistent Identifiers.

Introduction: This post introduces two tools developed by the Max Planck Institute for the History of Science, LoGaRT and RISE with a focus on Asia and Eurasia. […]The concept of LoGaRT – treating local gazetteers as “databases” by themselves – is an innovative and pertinent way to articulate the essence of the platform: providing opportunities for multi-level analysis from the close reading of the sources (using, for example, the carousel mode) to the large-scale, “bird’s eye view” of the materials across geographical and temporal boundaries. Local gazetteers are predominantly textual sources – this characteristic of the collection is reflected in the capabilities of LoGaRT as well, since some of its key capabilities include data search (using Chinese characters), collection and analysis, as well as tagging and dataset comparison. That said, LoGaRT also offers integrated visualization tools and supports the expansion of the collection and tagging features to the images used in a number of gazetteers. The opportunity to smoothly intertwine these visual and textual collections with Chinese historical maps (see CHMap) is an added, and much welcome, advantage of the tool, which helps to develop sophisticated and multifaceted analyses.

Introduction: Among the Nominees in the ‘Best DH Dataset’ of the DH Awards 2020, the TAO IC Project (http://www.dh.ketrc.com/index.html) leads us in a fascinating journey through the world of Chinese ceramics. The project, which is developed in a collaborative way at the Knowledge Engineering & Terminology Research Center of Liaocheng (http://ketrc.com/), exploits an onto-terminology-based approach to build an e-dictionary of Chinese vessels. Do you want to know every detail about a ‘Double-gourd Vase I’? If you consult ‘Class’ in the ‘Ontology’ section (http://www.dh.ketrc.com/class.html), you can discover the component, the function, from what such a vessel is made of, and what is the method to fire it. If you also wish to see how the vase appears, under ‘Individuals’ of the same section you can read a full description of it and, also, see a picture (http://www.dh.ketrc.com/class.html). All this information is collected in the e-dictionary for each beautiful item belonging to the Ming and Qing dynasties.

Introduction: This blog post by Lucy Havens presents a sentiment analysis of over 2000 Times Music Reviews using freely available tools: defoe for building the corpus of reviews, VADER for sentiment analysis and Jupiter Notebooks to provide a rich documentation and to connect the different components of the analysis. The description of the workflow comes with tool and method criticism reflections, including an outlook how to improve and continue to get better and more results.
In the next episode, we are looking behind the scenes of two ontologies: NeMO and the Scholarly Ontology (SO) with Panos Constantopoulos and Vayianos Pertsas who tell us the story behind these ontologies and explain how they can be used to ease or upcycle your daily works as a researcher. We discuss the value of knowledge graphs, how NeMO and SO connect with the emerging DH ontology landscape and beyond, why Open Access is a precondition of populating them, the Greek DH landscape …and many more!
