The German Longitudinal Election Study (GLES) routinely asks respondents about "the most important political problem". The open-ended responses sometimes include multiple topics, making manual coding a laborious and costly process. Since 2018, GLES has accumulated over 400,000 such responses. Our project aimed to streamline the coding process by developing a coding scheme and exploring more efficient methods. The outcome, a data product released in October 2023, represents the culmination of our efforts. In this presentation, we will guide you through the journey, from refining the coding scheme to experimenting with diverse models, ultimately employing the Large Language Model BERT for coding the responses.
