Visiting a museum as a kid, I sometimes wondered why I could hardly read anything in the medieval or early modern books and manuscripts displayed in the exhibition. Even after I learned Latin in school, the situation did not improve. I was not aware that people in former centuries used a lot more abbreviations than today, especially in Latin texts. As long as paper (or parchment) was very expensive, scribes and printers tried to save as much space as possible. Therefore, a sentence like “In principio fecit deus caelum et terram” could be abbreviated as “In prīcipio fecit de⁹ celū ⁊ ťrā” (“In the beginning, God created the heavens and earth” — the first verse of the Bible). You may have noted that these abbreviations worked differently than abbreviations like “WWW” or “U.S.” that we are familiar with today, and it would be nice if they could be resolved automatically with a Python script.
In the first episode of this miniseries, I explained how to use OCR with Transkribus to create a diplomatic transcription from images of 16th century Latin prints. However, the resulting text is full of abbreviations and may contain transcription errors. In both cases, Python scripts could help to normalize the text and to detect possible errors.
An indispensable prerequisite for pimping the Transkribus workflow with Python is flawless access to the data stored on the Transkribus server. It would not make much sense to manually download the data, then run some Python scripts on the command line, and finally upload the data again manually, especially when we talk about hundreds of pages to be processed. This episode will show how to download and upload transcriptions from and to the Transkribus server using Python. (Basic to intermediate knowledge of Python is required.)
The scholarly importance of “Priesterbibliotheken” (priests’ libraries) is well-known: they provide insight into what Catholic priests serving in the Holland Mission read or at least thought useful to own. Moreover, such libraries can tell us more about early modern Dutch Catholic spirituality, but also about the wider interest in books outside the remit of theology and pastoral care. Lastly, in particular libraries from the eighteenth century will also help to enhance our understanding of the schism which occurred in the Dutch Catholic Church. “Priesterbibliotheken (priests’ libraries) in the Dutch Republic” is a small pilot project which started at the IEG DH Lab in early 2021. The project aims to capture the bibliographical information contained in manuscript inventories of the libraries of Catholic priests serving in the Republic and making this available in digital form.

Since the 1980s, our knowledge on 16th century censorship has been growing constantly thanks to coordinated research projects and new sources. In over ten years of research, for instance, José Maria Bujanda and his team edited all printed catalogues of forbidden books issued by Catholic authorities in the 16th century (eleven volumes until 1999). This made it very easy to check whether a certain author or book was banned or not. With the opening of the Archive of the Congregation of Faith (the former Roman Inquisition) in 1998 a vast number of manuscripts became available that provided an insight into the internals of the Roman Congregation of the Index (founded in 1572) and the decision making processes of the censors. These processes are particularly interesting for books that were not totally banned but expurged, meaning that the censors deleted or modified passages considered “heretical” and then reprinted the book. In many cases, the only way to find out what they actually changed is to compare the original with the expurged edition line by line and word by word. Because Rome was by far not the only Catholic authority that expurged books, the same book was sometimes also expurged by the Spanish Inquisition, the Sorbonne in Paris and other local inquisitors. They all had their own censoring procedures resulting in different expurgations. If we want to uncover the differences between these expurgations, we have to repeat the tedious manual comparison over and over again. These repetitive comparisons are exactly the kind of “boring stuff” that could be automated with Python. „Uncovering censorship in the 16th century with Transkribus and Python.

Before digital humanists can do things with data, they first need to collect them, and web automation (or more specific methods of web scraping) can be a quick way of gathering a large amount of data. While web automation denotes every remotely controlled action performed on the web, web scraping, web mining or web harvesting are focussed on reading and processing information (found on websites). This blog post presents useful Python packages for these tasks and explains the advantages of working with browser profiles. „Doing Digital History with Python IV: web automation“ weiterlesen
Since I started my project on the schism in the Catholic Church in the eighteenth-century Dutch Republic in the summer of 2019, I have been creating a dataset that comprises the information contained in lists of baptisms, burials, and marriages. This information enables me to trace the movement of Catholics to another, competing Catholic Church in the context of the schism. Consider, for example, Henricus Verbruggen and Maria Blomevelt. They baptised their first two children in a mission station that was part of the Church of Utrecht but had their third and last child baptised in the Roman Catholic Church (see Fig. 1). „Dealing with uncertainty and capturing the underrepresented“ weiterlesen

It all started with the seminar on network analysis in the summer semester of 2020. After learning about the basics of network theory and building networks in Python ourselves, the teachers Aline Deicke and Demival Vasques Filho asked us students to work in groups to develop a project combining our individual humanities backgrounds with network analysis. We are specialists in art history, which we wanted to include in the project. On top of that, the IEG DH Lab provided us with funds and support to further explore the application of network analysis in the field, e.g. whether art history datasets are available and to what extent they are usable or which art historical analyses or topics have already been done. The research project was kept relatively open, so we were able to look at the subject matter first. Tasks and questions developed during the following research. „LinkedArt: exploring network analysis in art history“ weiterlesen

Die Transformation von digitalisierten Druckwerken von einer Bilddatei zur maschinenlesbaren XML-Datei ist für zahlreiche Methoden der Digital Humanities ein wichtiger Schritt in der Datenaufbereitung. In diesem Beitrag präsentieren wir einen Ansatz auf Basis eines Python-Skripts am Beispiel eines Werkes mit einer besonderen Binnenstruktur: Der Bomber’s Baedeker war ein „Reiseführer“, welcher von der Royal Air Force genutzt wurde, um während des 2. Weltkrieges deutsche Industriestandorte anzugreifen. „Text zu XML mit Python auf Basis des „Bomber’s Baedeker““ weiterlesen
In April 2020, we started a series of case studies to introduce researchers working with historical sources to data analysis and data visualisation with Python. Today’s blog post covers topic modelling with the Python packages Gensim, spaCy, NLTK and SciKit learn.
Topic modelling is one of the central methods of Natural Language Processing (NLP), the „automatic manipulation of natural language, like speech and text, by software.“ (Jason Brownlee: What Is Natural Language Processing?, in: Deep Learning for Natural Language Processing, 22nd September 2017) In its most basic form, a „topic“ modelled by software displays word co-occurrences in texts, assuming that the frequency of co-occurrences defines certain areas of meaning. „Doing Digital History with Python III: topic modelling with Gensim, spaCy, NTLK and SciKit learn“ weiterlesen
The IEG is involved in RESILIENCE, a research infrastructure project for Religious Studies and related disciplines, involving twelve partner institutions from ten European countries.
The acronym stands for “REligious Studies Infrastructure: tooLs, Experts, conNections and CEnters in Europe” and the goal is a pan-European research infrastructure (RI) which provides access to sources, research results, expertise and tools for researchers and individuals interested in religion-related topics.
Digital Humanities have been transforming research in Europe and RESILIENCE aims for driving forward the digital turn in Religious Studies by stimulating the applicating of innovative methodological approaches in this field. Digital data and services designed for the needs of transdisciplinary research related to religions will be made available within a single ecosystem accessible for researchers as well as non-academics worldwide. „RESILIENCE – A Research Infrastructure for Religious Studies“ weiterlesen
COVID-19 has posed a challenge, to put it mildly, to how most of us go about living our lives. Either in our personal life or work life, most if not all of us had to make significant adaptions in order to deal with a world that still is in the grasp of pandemic. The experience I’d like to focus on in this blog post, is that of doing research at these unprecedented times. Fairly soon after COVID-19 broke out, it became clear that it would have huge implications for researchers and teachers. Due to travel bans and other restrictions, virtually all conferences were either canceled or were held online in some form or another. In a short time span, teachers across the world had to go to extraordinary lengths to move their courses online. As libraries and archives closed their doors and traveling to or from particular countries became severely restricted or even impossible, the access to primary and secondary sources, the very fuel of our research, was hampered to a large degree. „Research in times of COVID“ weiterlesen

In the second edition of Doing digital history with Python, I would like to address word clouds as a visual method of finding patterns in texts (see critical reflection in Basic Text Mining: Word Clouds, their Limitations, and Moving Beyond Them). Word clouds display the frequency or importance of individual keywords in individual texts or entire corpora. There are many ready-made tools in multiple languages that help you create word clouds in different designs, such as the in-built word cloud generator in Voyant Tools or browser-based tools such as Wortwolken.com. However, not all of them may be suitable for your specific use case. „Doing Digital History with Python II: creating custom Word Clouds“ weiterlesen

Vor ungefähr drei Monaten fand die DHd 2020 „Spielräume: Digital Humanities zwischen Modellierung und Interpretation“ in Paderborn statt und wie jedes Jahr brachte auch diese DHd-Tagung nicht nur Einblicke in aktuelle Forschungsfragen, sondern versammelte eine Community und schaffte Gelegenheiten für Diskussionen. In der mittlerweile siebten Auflage der Konferenz kam im Austausch mit meiner Peergroup – also jenen, die schon ein paar Jahre länger im Job sind – mehrfach das Gespräch auf beobachtete und/oder selbst vollzogene berufliche Veränderungen der jüngeren Zeit. Die Überlegung, wer von uns denn in den vergangenen Jahren schon wo und mit wem zusammengearbeitet hatte, nahm ich mit und fragte mich: Wie könnte ein Personen-Affiliationen-Netzwerk der DHd-Tagung 2020 aussehen bzw. wie erstelle ich es auf möglichst geschmeidige Art und Weise?
At the beginning of March, I went to New Zealand for a research visit with a planned duration of four weeks. This visit was part of a collaboration involving the IEG DH Lab and Te Pūnaha Matatini, a New Zealand centre of research excellence for complex systems and data science hosted by the University of Auckland’s Department of Physics.
The main goal of the visit was to further develop our research on the structure of higher-order networks, that is, networks which account for interactions between individuals stemming from their membership to groups. Higher-order networks are usually represented by either bipartite (two-mode) networks, or hypergraphs, or simplicial complexes. Our last publications on this topic can be seen in the Journal of Complex Networks and the Physical Review E (also available on arXiv, here and here).
I arrived about one week before New Zealand closed its borders to the world, allowing only citizens and long-term residents to enter into the country. „Research visit in New Zealand: Modelling the spread of COVID-19 on higher-order networks“ weiterlesen
