Feldforschung mit Linked Open Data: Die Forschungslandschaft der digitalen Geschichts- und Geisteswissenschaften auf Wikidata abbilden … und auffinden

In diesem Beitrag stelle ich anlässlich der Anfang März in Bielefeld stattfindenden DHd2025 Konferenz mit dem Thema “Under Construction” kurz unser offenes und community-fokussiertes Field Mapping von Digital Humanities und Digital History in Deuschland, Österreich und der Schweiz auf der Basis von Wikidata und SPARQL-Abfragen vor. Ziel dieses Blogbeitrags ist es, unseren Arbeitszyklus zum Field Mapping vorzustellen sowie einen Vorschlag der Nutzung dieser Daten auf Wikidata und den Wikidata Query Service mit Hilfe von SPARQL-Abfragen vorzustellen.

Datenbereinigung und –aufbereitung als zentrale Tätigkeit in der Digital History

Wenn wir digitale Datensätze (wieder-)verwenden, sind wir zunächst mit der grundsätzlichen Modellierung von Daten konfrontiert. Das bedeutet, dass die Daten, die wir nutzen, nie ohne Theorie oder Modell erstellt worden sind. Sie sind demnach eine Teildarstellung und abhängig von den ihnen zugrunde liegenden Annahmen. Jeder Datensatz wird für einen bestimmten Zweck erstellt, und seine Übernahme für ein anderes Projekt erfordert immer eine Bereinigung oder Umstrukturierung der Daten. Im Laufe der Erstellung einer Tool Registry und eines Field Surveys zur Digital Humanities und Digital History in Deutschland, Österreich und der Schweiz im Rahmen des NFDI4Memory habe ich mit unterschiedlichen z.T. großen (wenn auch noch relativ übersichtlichen) Datensätzen gearbeitet. Die dabei gemachten Erfahrungen in der Bereinigung und Aufbereitung von Daten teile ich in diesem Blogbeitrag.

Preprint published: NER4all or Context is All You Need


The Chair for Digital History is happy to announce that we published our first preprint on arXiv:

Torsten Hiltmann, Martin Dröge, Nicole Dresselhaus, Till Grallert, Melanie Althage, Paul Bayer, Sophie Eckenstaler, Koray Mendi, Jascha Marijn Schmitz, Philipp Schneider, Wiebke Sczeponik, Anica Skibba, NER4all or Context is All You Need: Using LLMs for low-effort, high-performance NER on historical texts. A humanities informed approach, arXiv (4.02.2025), DOI: https://doi.org/10.48550/arXiv.2502.04351

Abstract:
Named entity recognition (NER) is a core task for historical research in automatically establishing all references to people, places, events and the like. Yet, due to the high linguistic and genre diversity of sources, only limited canonisation of spellings, the level of required historical domain knowledge, and the scarcity of annotated training data, established approaches to natural language processing (NLP) have been both extremely expensive and yielded only unsatisfactory results in terms of recall and precision. Our paper introduces a new approach. We demonstrate how readily-available, state-of-the-art LLMs significantly outperform two leading NLP frameworks, spaCy and flair, for NER in historical documents by seven to twentytwo percent higher F1-Scores. Our ablation study shows how providing historical context to the task and a bit of persona modelling that turns focus away from a purely linguistic approach are core to a successful prompting strategy. We also demonstrate that, contrary to our expectations, providing increasing numbers of examples in few-shot approaches does not improve recall or precision below a threshold of 16-shot. In consequence, our approach democratises access to NER for all historians by removing the barrier of scripting languages and computational skills required for established NLP tools and instead leveraging natural language prompts and consumer-grade tools and frontends.

Shawn Graham: Do It Yourself Digital Golems. Experiments with various AI, neural networks, and other technologies for archaeology

The golem is a creature animated by the words in its head. Emerging from Jewish traditions, the words that did the animation had connections with divinity, but the golems themselves despite this spark of the divine toiled at mundane chores. But sometimes, the golems would get out of control, and become figures of terror. My none-too-subtle analogy is this: animated by the ‘words in their heads’, the anthropomorphized neural networks of contemporary ‘ai’ (and ‘agi’: artificial general intelligence) are similar figures, with similar connections to the divine (we are told: ‘agi’ will transcend us; ‘agi’ will bring about the singularity; ‘agi’ will make us all posthuman). In this talk, I will explore some of my experiments trying to teach these technologies ethically and critically. I will explore some of the ways I have been trying to raise my own digital golems for my mundane archaeological needs. This is a talk filled with failure and experimentation. But maybe, also, something useful.

Folgert Karsdorp & Mike Kestemont: The application of unseen species models in history: correcting registration bias in nineteenth-century police reports from Brussels

Researchers of the past – whether historians, literary scholars or archaeologists – depend on the sources that have stood the test of time. That sample of history is usually far from complete, however. There are numerous reasons for this, such as natural causes (e.g., fires or floods), decisions at the level of archival policy (what do we preserve and what do we not?), and biases in the formation of the archives themselves. Data representing lower classes were long considered less relevant, for example, and thus socioeconomic factors likewise play a role in the survival of sources. In a series of recent experiments, we have explored how statistical methods from ecology can help us identify such gaps and biases in our knowledge. Those methods all find their basis in “Unseen Species Models,” which were originally developed to estimate the number of unique species in an environment. Just as ecologists try to estimate biodiversity from an incomplete sample, we apply the models to incomplete historical archives to measure the actual cultural diversity.

Ursula Lehmkuhl: Building Data Competencies for Historians: Perspectives from the NFDI4Memory ‘Data Literacy’ Program

The NFDI consortium 4memory includes a task area that focuses on enhancing Data Literacy in historically oriented research and education. This task area seeks to promote cultural change in the historical profession by developing methodological and curricular innovations, aiming to integrate Data Literacy competencies at all levels of history education. This includes BA, MA, and PhD programs, as well as specialized courses in area history (e.g., African, Asian, and Latin American histories). We emphasize mainstreaming Data Literacy rather than limiting it to specialized programs, fostering a global and interdisciplinary approach to historical research under digital conditions. The presentation explores issues surrounding digital hermeneutics, historical data criticism, and the distinct challenges posed by area histories.

Amanda Regan: Mapping the Gay Guides: Using Digital History to Explore LGBTQ Travel Guides, 1965 – 2005

Mapping the Gay Guides (MGG) relies on the Damron Guides, an early but longstanding travel guide aimed at gay men since the early 1960s. An LGBTQ equivalent to the African American “green books,” the Damron Guides contained lists of bars, bathhouses, cinemas, businesses, hotels, and cruising sites in every U.S. state, where gay men could find friends, companions, and sex. The online mapping project explores different dimensions of American gay life through time, from bars and nightlife, bookstores, cinemas, and churches. Users to the site are able to navigate and investigate the dynamic and sometimes disappearing nature of LGBT spaces over time.

Moritz Feichtinger: Just a Little Bit? Historicizing Born-Digital Objects

The information age is intrinsically digital. Knowledge, culture, and communication are increasingly created, transmitted, processed, and stored in digital formats. Consequently, historical inquiry, particularly when engaging with the latter half of the 20th century and beyond, must grapple with digital artifacts. These artifacts, often termed “born-digital” objects, are created by and within digital environments. Their scale, diversity, and inherent technical and cultural characteristics present distinct challenges for historical research, requiring historians to adapt established methodologies, particularly source criticism, to address these nuances.

»Ohne die richtige Einstellung ist erfolgreiches Scheitern unmöglich. Man muss Scheitern wollen – sonst wird es nur eine peinliche Niederlage.«
Alexander Florin, 2013: Erfolgreich Scheitern (via DWDS-Korpussuche)

Erzählen vom und Sprechen über das Scheitern – das ist die Idee hinter dem Konzept ‘FuckUp-Night’.1 Über die Kommerzialisierung dieser Idee und den Grund für den legally distinct Namen dieser Veranstaltung lässt sich streiten; das Konzept hat sich aber bereits seit mehr als zehn Jahren bewährt.
Dem gemeinsamen Sprechen über Scheitern wohnt eine radikale Kraft inne: Wir alle scheitern im Großen wie im Kleinen – meist eine sehr einsame Erfahrung. Aber genau diese Einsamkeit gilt es gemeinsam zu durchbrechen!
