We are delighted to have been awarded the Best Paper Award at the 19th International Conference on Design Science Research in Information Systems and Technology (DESRIST 2024). The paper Designing an LLM-based Open Data Assistant for Effective Use by Till Carlo Schelhorn (Karlsruhe Institute of Technology), Ulrich Gnewuch (University of Passau), and Alexander Maedche (Karlsruhe Institute of Technology) presents meta-requirements and proposes initial design principles on how to design a Large Language Model based open data assistant for effective use. Subsequently, the principles are instantiated in a prototype and evaluated in a focus group with experts from a medium-sized German city.
