Impresso 2: Connecting Historical Digitised Newspapers and Radio. A Challenge at the Crossroads of History, User Interfaces and Natural Language Processing

The Impresso project pioneers the exploration of historical media content across temporal, linguistic, and geographical boundaries. In its initial phase (2017-2020), the project developed a scalable infrastructure for Swiss and Luxembourgish newspapers, featuring a powerful search interface. The second phase, beginning in 2023, expands the focus to connect media archives across languages and modalities, creating a Western European corpus of newspaper and broadcast collections for transnational research on historical media. In this presentation, we introduce Impresso 2 and discuss some of the specific challenges to connecting newspaper and radio.
