Dear colleagues,

deadline approaching - roughly only a week left!

TU Berlin is looking for a PhD candidate and Researcher, offering a 3 years contract with optional prolongation in our joint "News Polygraph“ project. We will primarily focus on applying various natural language processing models (especially transformer-based models) in the area of text-based fake news detention. In addition, various models will be explored and implemented in the domain of explainable AI, in order to make language models more transparent and reliable for end users. Moreover, data handling for English and German inputs is required for creating balanced training data to prevent biases in data, but countermeasures for biases in NLP models should also be handled.

Real end users are involved in this project, e.g. Rundfunk Berlin Brandenburg (rbb - Berlin and Brandenburg’s official broadcaster on TV, radio and online) and Deutsche Welle (DW - Germany’s official voice for Germany abroad, broadcasting in more than 50 languages around the world), for whom a fact checking platform is to be developed that enables journalists to verify information in different modalities. In addition, several project partners from science (German Research Centre for Artificial Intelligence SLT and Fraunhofer IDMT) and industry (Ubermetrics, Transfermedia, Crowdee and Delphai) will work on similar solution approaches for the modalities audio, image and video. Finally, the project integrated crowd-wisdom harvesting automation into AI modelling in order to fuse human and artificial intelligence the best ways possible.

This project combines both scientific developments with practical requirements in order to be able to process and detect false information faster and more comprehensively. If desired and suitable, a PhD in the subject area can be pursued as well as publication and presentation of project and research results in scientific journals, at conferences and workshops.

Application deadline: May 18 More details: https://tub.stellenticket.de/de/offers/164721/?locale=enhttps://tub.stellenticket.de/de/offers/157309/?locale=en

Best regards from Berlin, Tim
