Latent Dirichlet Allocation (LDA) topic modeling is a method for analyzing the distribution of semantic word clusters, so-called “topics” in collection of texts. In history it can be used for exploring the content of a corpus of digital sources.
Topic modeling is based on a statistical analysis of co-occurrence for words. It does not use dictionaries or external training data. Topic modeling is a flexible method for computational text analysis.
The Topics Explorer of DARIAH-DE is designed as a very user friendly tool. It allows researchers to experiment with topic modeling on their own computers.
The work flow from plain text to visualized results is done in a graphical user interface. The software allows users to load a collection of plain-text or xml-files and to analyze it by means of the LDA algorithm.
Ten years ago, the Programming Historian was born at the Network in Canadian History & Environment (NiCHE) In 2008, William J. Turkel and Alan MacEachern introduced the project by writing a series of tutorials aimed at historians looking to build their technical skills. It has attracted more than 1.3-million visitors.
The project was originally inspired by a gap. While Digital History had been an excellent resource for those seeking to put the past online, Turkel and MacEarchern worried that historians would lack to create digital tools for research. In 2008, the project has evolved into the co-written Programming Historian, focusing heavily on Python.
But the project had not yet reached its potential. The digital era had changed the types of problems many historians were having with their sources – particularly digital or digitized sources. Yet the traditional scholarly environment did not provide a venue for those conversations.
Some of the earlier contributors were environmental historians as in other countries, too. Jim Clifford, Daniel Macfarlane, and Josh MacFadyen produced a series of digital mapping lessons in 2013, which formed the cornerstone of our Geospatial Historian series. Since then, the project has branched in new directions, including tutorials as divergent as augmented reality, and data mining.
The project continues to grow in new directions. It is on the lookout for a French Language Team to help us move bravely forth into our second decade.
If you are interested in Digital History and read German please have look to my book “Geschichte Digital – Historische Welten neu vermessen”; You’ll find a short English summary on https://wethink.hypotheses.org/2161.
The University of Zurich is developing a Digital Society Initiative (DSI) to engage with the impact of digital technology that should be studied historically. Monika Dommann, Martin Dusinberre and Gesine Krüger therefore plan to establish a History Lab within this Initiative. They argue that digital history should have to play a key role there because Big Data, surveillance, privacy, access rights and the circulation of cultural artefacts and other digitally mediated social interaction demand a deep historical understanding. Find here a short cut of the concept.
What are the Digital Humanities (DH)? This question of a quite long standing debate is treated in a new open access book in the Springer Series on Cultural Computing: Computation and the Humanities, Towards an Oral History of Digital Humanities. Julianne Nyhan and Andrew Flinn of the Department of Information Studies at the University College London (UCL) state that the DH form an interface between computing and cultural heritage. They believe that DH transforms the objects and the methods of studying them. They did oral history to know more about this.
The Journal accepts articles from various disciplines such as ancient science, philosophy, political science and sociology, and naturally, history, too. The submitted articles are subject to a peer-review procedure. There is an anti-plagiarism checking, too.
Close reading or Distant reading: A new book of proceedings entitled “Reading Historical Sources in the Digital Age” («Lire des sources historiques à l’ère numérique») has just been published. The contributions of this volume base on selected papers presented at the conference of the University of Luxembourg held in 2013.
Things have power to act, Bruno Latour says. This French author alternates between natural science, social science and philosophy. For him, who founded the influential actor-network-theory (ANT), computer and their programs are hybrids between the linguistic and the real. In the language of ANT, he calls them Aktanten.
Things unfold their power because they are connected with people.
L.I.S.A., the scientific platform of the Gerda Henkel Foundation, on July 14, 2016 published a report of the outcome of a symposium that was organised by the Deutsche Forschungsgemeinschaft (DFG) and held in the Villa Vigoni in Menaggio at the beautiful Lake of Como, May 26 to 29, 2016. The Villa Vigoni is an instution that “fosters the relationships between Italy and Germany in the fields of scientific research and culture in a European perspective”. Literature was in the focus of the symposium.
Clio online, the professional portal of the historical sciences in Germany recently published a new manual. It maps the field of digital history including institutional infrastructures and tools. The aim is a practical one: To give a fact-based introduction to the state of digital professional information and an overview of the most important tools and instruments. Thus, it is aimed at both students and teachers, as well as to researcher and historians who need an introduction to the state of the professional information for their area of research.
The guide is structured along the following issues: Digital working methods and techniques, collections, epochs, regions and topic.
The guide is in German and edited by Laura Busse, Wilfried Enderle, Rüdiger Hohls, Gregor Horstkemper, Thomas Meyer, Jens Prellwitz and Annette Schuhmann. You find it here: http://guides.clio-online.de/
Digital History is a trend in Switzerland, too. But, its position is not yet a solid one. This becomes evident, if we check the program of the fourth edition of the Historical Days in Switzerland, June 9 to 11, 2016, in Lausanne. Only two panels explicitly discuss digital media and methods: Jan Hodel, Mareike König and Nadine Fink present cases of how historians work with social media. And Anne Jobin, Hannes Mangold, Stefanie Prezioso and Valérie Schafer present the power of algorithms in historical social practices as the dragnet investigation in Switzerland, the regulation of information in France and the search for episodes and their perception in the case of World War I. It will be interesting to hear the comment of Nicolas Cachereau and follow the discussion moderated by Enrico Natale and Christiane Sibille.
Guido Koller, Geschichte Digital – Historische Welten neu vermessen, Stuttgart, 2016
Die digitale Kommunikation prägt inzwischen das Berufsbild der Historiker entscheidend. Heute ist Norm, was vor 20 Jahren noch Ausnahme war: Historische Welten werden digital vermessen und analog interpretiert. Wie Historiker denken, lehren, schreiben ändert sich durch die Digitalisierung schon heute und wirkt auf das Schreiben von Geschichte zurück: Mit Algorithmen verarbeiten Forscher heute große Datenmengen, die völlig neue Perspektiven und Herangehensweisen an die historischen Quellen ermöglichen. Das Buch beschreibt den Stand des digitalen Wandels für die Geschichte als Teil der Geisteswissenschaften und diskutiert die Perspektiven über die Zukunft des Big Data in den historischen Wissenschaften. Ein Serviceteil, in dem Infrastrukturen, Portale, Tools, Standards und Blogs vorgestellt werden, ergänzt dieses Buch.
The digital communication characterizes the professional profile of historians. Today is standard, what, 20 years ago, was the exception: Past worlds are measured digitally and interpreted analogously. The digital change captures the production and communication of historical knowledge and affects the writing of history: With algorithms, we process large amounts of data and create a new digital information society, a network, a hybrid constellation of people and things. The book describes the state of the digital change for the History as part of the Humanities and discusses its further perspectives. It includes a service part, where infrastructures, portals, tools, standards and blogs are presented.

The new German Zeitschrift für Digitale Geisteswissenschaften (Journal for Digital Humanities) of the Forschungsverbund Marbach, Weimar and Wolfenbüttel, supported by the Bundesministerium für Bildung und Forschung in its first volume discusses limits and possibilities of the Digital Humanities.
The editors, Constanze Baum and Thomas Stäcker, want to present theories, methods and projects of the Digital Humanities in the German speaking part of Europe. Not all texts are already available. But what is there is really interesting – here a small selection of articles:
