Data from the Community

Offers for research data for integration within the context of Text+

Running Call: Direct link to submit offers for research data (German online form)

Together with you, we would like to sift through the rich treasure of research data and possible applications offered by the humanities and other disciplines and contribute productively to the NFDI Text+ initiative. It is precisely through the diversity and quantity of research data and a wide range of research questions that a stable and multi-faceted basis for a research data infrastructure is to be created.

Within the Text+ initiative, three data domains are distinguished: Collections, Lexical Resources and Editions. In these data domains, you can enrich the initiative with your offers of research data, research questions and research tasks.

The humanities community in all its diversity is the most important reference point for Text+ and we would like to represent it with your help. We would therefore like to invite you to participate and to help shape the NFDI.

Your research data can complement the Text+ offer and can be included in the pool of representative data for Text+. The governance of Text+ intends that the Scientific Coordination and further development of the three data domains of Text+ shall be exclusively in the hands of expert scientists. This further development will be based on the data pool. In order to obtain a structured overview of the data stocks relevant to the community, we have created a questionnaire.

Any feedback given until August 16, 2020 could be included in the preparation of the application. Later submissions are possible using the online form. For further questions please contact office[at]

Results of the Data Call

Below, you see some of the data that were proposed by the community for integration in the Text+ infrastructure.

Tailored Corpora and Topic Models for Japanese Parliamentary Minutes (provisional title)

The Japanese Diet has made all speeches since 1947 public through an XML interface. The enormous number of texts allows for tracing the evolution of concepts (if understood as corresponding to Japanese words) in discourse if methods of distant reading are employed. At the German Institute for Japanese Studies (DIJ), such analyses are carried out using LDA topic models. In addition to the models, systematic analysis also uses metadata that is provided through the public interface (like date, committee, name of the speaker) and custom data structures based on this (like networks).

170 “soldiers’ letters” from the years 1745 to 1872. The letters come to a small extent from older but reliable editions (no longer protected by copyright), but mainly from our own archive work, and were therefore transcribed and published for the first time by the editor, Marko Neumann, based on the manuscript. These are available on the website of the Universitätsverlag Winter based in Heidelberg and can be downloaded from there free of charge. This corpus is extremely valuable from both a linguistic and a historical perspective, in particular from a cultural, literary and military-historical perspective.

For the hurdles (from a legal point of view) and difficulties (with a view to the form of publication and especially the data format) for the re-use of this valuable data, cf. the user story belonging to this data offer “Soldiers letters of the 18th and 19th centuries: From the PDF edition to reusable, interoperable research data”.

Disciplines (DFG)102104105107
Disciplines (descriptive)Philologies, Theology, Edition Philology, Papyrology

In the Virtual Manuscript Room (VMR), the conventional short list of Greek manuscripts is supplemented by all the information available on the individual manuscripts. Above all, as far as the owning institutions agree, photos of the manuscripts are made available via an appropriate website. For this purpose, the microfilm holdings of the INTF are scanned (in some cases new photos are also obtained) and the content is indexed in such a way that they are linked to the transcripts of the manuscripts which were created in the INTF. There are also links pointing to photos and information elsewhere on the internet. The VMR has meanwhile been expanded into an interactive edition platform and serves as a working basis for the Editio Critica Maior (ECM) of the Greek New Testament created in the INTF, but can also be used for other text-critical editions of handwritten works. At the moment the ECM and VMR are growing together into an interactive critical edition of the New Testament.

We distinguish an “old” and a “new” text corpus (under construction). Both corpora are connected by different access methods. The data basis for the latter currently (2020) comprises around 43 million tokens. The texts are annotated step by step (including normalization / lemmatization). The search does not require in-depth knowledge of historical writing and the variety of forms, but it currently does not access a lot of texts. The old text corpus comprises more than 23 million tokens, of which around 15 million are available online. The texts are not annotated and hardly processed, the old corpus only provides the original spelling. In addition, the texts have not been corrected so that (copying) errors are to be expected.

The resource is a linguistic corpus based on the digital edition of Acta Pacis Westphalicae (APW). For this re-use and the non-commercial publication of the data, the institutions holding the respective rights have given written permission. From a linguistic point of view, this resource, originally prepared for historiography, is extremely valuable: the German, French, often multilingual technical or informal text types represent different registers of an important phase of language change. The edition criteria show minimal interference with the original text. The following resources are available in the corpus so far (marking of metadata, separation of text data):

  • French correspondence from the Acta Pacta Westphalicae (1644–1647), annotated with TreeTagger parameters for classical French from the PRESTO project (DFG / ANR), 2,640,000 tokens
  • German correspondence from the Acta Pacta Westphalicae (1643–1648), approx. 835,000 tokens, not yet annotated

Disciplines (descriptive)historical linguistics, linguistic typology, psychology, neuroscience

The original Database of Cross-Linguistic Colexifications (CLICS) has established a computer-assisted framework for the interactive representation of cross-linguistic colexification patterns. It has proven to be a useful tool for various kinds of investigation into cross-linguistic semantic associations, ranging from studies on semantic change, patterns of conceptualization, and linguistic paleontology. But CLICS has also been criticized for obvious shortcomings. Building on standardization efforts reflected in the CLDF initiative and novel approaches for fast, efficient, and reliable data aggregation, CLICS² expanded the original CLICS database. CLICS³ – the third installment of CLICS – exploits the framework pioneered in CLICS² to more than double the amount of data aggregated in the database.

Modality/ies written
Disciplines (DFG) 101 102 104 105 107
Disciplines (descriptive) Church History, Ancient History, Epigraphy, Archaeology, and the History of Religions.

ICG entails almost all Christian honorary, votive, building, and funerary inscriptions from Asia Minor and Greece. Currently the expanding database comprises 4297 Greek inscriptions. Each monument has been assigned an ICG number. Each ICG entry features the original Greek text, a German or English translation, a concise critical apparatus and commentary, one or several images whenever available (i. e., a photo or drawing, to date 5812 images), as well as all the relevant information pertaining to dating, typology, ancient and modern provenances, current location, and circumstances of discovery, and is annotated with geo-coordinates linked to online digital maps supported by Pleiades, the iDAI.gazetteer, and GeoNames. For the archeological evidence on the rise and spread of Christianity in Attica, catalogues on the early Christian churches and Late Antique cemeteries in Attica have been completed.

ICG gives geographically structured access to hitherto neglected locatable primary sources by having collected thousands of inscriptions previously scattered over hundreds of publications (since the 19th century). As a first digital database on Christian Greek Inscriptions, it opens up huge possibilities for interdisciplinary collaboration between historians interested in the rise and expansion of Christianity and its footprint from the late Imperial to Early Byzantine periods in Asia Minor and Greece and is a useful tool for researchers from Church History, Ancient History, Epigraphy, Archaeology, and the History of Religions. The database can be accessed on-line through a ‘guest’ log in and searched and/or browsed by ICG reference numbers, regions, ancient and modern locations, images, inscription types, or bibliographic entries. In addition, search functions allow users to perform queries of the original Greek texts, translations, and the other metadata, using a variety of filters (e. g., region, dating, location, type). Since each ancient and modern location has been attributed geo-coordinates and linked to online digital maps, ICG is an invaluable resource for research on the spread, social structure and profile of Early Christianity and the development of the clergy from the 3rd to the 6th centuries. The database opens the door to study local Christian communities, their cultural background, gender roles and family relations, forms leadships, use of scripture, rise of ascetics, and theology and to compare them with non-Christian compatriots. First results can be seen in the monographs on Lycaonia by C. Breytenbach and C. Zimmermann (Leiden: Brill, 2018) and on Attica by C. Breytenbach and E. Tzavella (Leiden: Brill, [in press]). 

Currently ICG forms the basis for the writing of 9 monographs on the rise of Christianity in regions of Asia Minor (Ionia, Lower Meander, Phrygia, Galatia), in Greece (Corinth and the Peloponnese, Attica, Thessaly, and Macedonia) and the Balkans. It also supplements the archaeological evidence in the writing of monographs on the rise and spread of Christianity. Reference to ICG make the voluminous primary data, including maps and images, available on-line to the readers of publications. If ICG can be expanded beyond Asia Minor and Greece, it would greatly facilitate future research on early Christianity on Greek Islands, in Cyprus, Syria and Palestine, and in Egypt.
