eAQUA digital resources
This webpage is the entry point to the digital tools and proposals related to the eAQUA project. The website is optimized for fast online access and tiny online payloads.


eAQUA offers several tools for text analysis and research on relevant corpora of the digital classics. eAQUA includes howtos, case studies and a online front end / information visualization / export. You can reach it with http://www.eaqua.net


The main objective of the eComparatio project was to develop a software that is able to achieve an extremely accurate alignment of a text-diff-analysis in a synoptic representation. You can use eComparatio as a tool to compare text or as a tool to prepare your digital text edition. It provides superior visualization and it outperforms competitors like Tustep, collateX or alternatives because it is the most powerful text diff software that also incorporates a solution for text transposition. The tool is realized as an browser based local application. Visit http://www.ecomparatio.net


This is the website of the project (Ir)reproducibility of Scientific Research in the Digital Humanities? (funded by VolkswagenStiftung, 2023-2026). The project will work on guidelines, discrimination and examples for reproducible scientific work in the digital humanities. Visit http://www.replicatio.science/

Github Repository (resources and software)

The github repository of the Chair of Ancient History University of Trier provides a lot of software, programming and data resources for text and image analysis. It is the place you can contribute to the software and file bugs. Visit https://github.com/ecomp-shONgit

CT-scan copus

This repository povides CT-scan data (and 3D data) from ceramic artifacts (sherds and objects). Visit http://replicatio.science/~khk/ctscancorpus/


stylo is a tool to do text analysis in terms of representing a text as vector, do distance matrix computation and clustering. It is easy to use, unless you want it to be a scalable tool. Since this computational method is not very resource hungry we decided to port it to a browser application. We added crucial method to preprocess encoding, format and representation of text which were missing in the R bases stylo package. Also we added some experimental tokenizer methods. Please visit http://replicatio.science/~khk/styloonline/

string/format tools online

The string tools provide an in browser solution for text preparation. If you like to work with third party text analysis / visualization software (stylo, gephi etc.) the tool provides everything to convert Greek and Latin texts to a usable form. If you have ill formed TEI XML you can use the tool to reformat the XML to work with your desired software. Also if you want alternative tokenizer the tool will help you out. It is the Swiss army knife for digital classicists who work with own corpora. Visit the browser based application through http://www.ecomparatio.net/~khk/onlinetnormtool/


A tool to extract an Index signorum criticorum (ISC), Index verborum (IV) and Index locorum (IL) from any webpage (or plaintext).

Amphora DB Model

A visual and statistical analysis of stamped amphora from the CEIPAC database. The goal of the analysis is to find hints for trade routs.

A tool to view, compare and draw sail boat polar plots.

Visualization of a small feed forward (so called) artificial neuronal network. The animation has a didactic purpose. We attempt to give an alternative visual impression of the mathematical process of approximation, that forms the the implementation of an artificial neuronal network.

Stylo-AH (R version)

We added some features to the stylo R package (link), that relate to the work with texts that were written in Latin and Greek.

measure display

This online resource presents distance measures and their comparison with the help of an visualization. This is an attempt to consolidate methods that depend on measure computation as expression of similarity or as basis for sorting.
