The project DYLEN bridges the fields of linguistics, digital humanities and computer science in order to explore the diachronic dynamics of lexical networks on the basis of large-scale authentic language data. The project will reuse language data that is already available at the ACDH-CH, namely the Austrian Media Corpus (AMC) and the Corpus of Austrian Parliamentary Records (ParlAT). The project will enrich the already available digital toolbox with a freely available tool for network analysis and visualisation and will enhance already existing data with additional annotations.
