Social inequalities in health are a key challenge and can be largely traced back to social differences in health behaviors, such as food decisions. Food decisions are one of the key behaviors to preserve health and prevent chronic-degenerative diseases that are the major cause of death in Western countries. Yet surprisingly little is known about how, when, where, and by whom these food decisions are made. The goal of the proposed research project is to further develop and apply a multi-method approach which combines methods from informatics, sociology, and psychology to better understand everyday social decisions, using the example of family food-decisions. Developing such externally valid methods that take the social context into account is central to better understand inequalities in nutrition and health.

TransforMA consolidates existing transfer activities and networks of the participating universities and utilizes them as a catalyst for expanding connections between universities, industry, and society.
In the subproject 'Technology Demonstrators,' a demo apartment is set up to showcase the use of modern technologies to support daily life. The demonstrator by the University of Mannheim is being developed by the Chair of Artificial Intelligence and focuses on the topics of health and nutrition within the context of a demo kitchen.

In the research project KISync, we aim to investigate how artificial intelligence (AI) methods need to be applied to synchronize the decision problems of various processes in operational supply chain planning under the influence of uncertainties. The focus will primarily be on the intra-company planning in competitive supply chains with limited information exchange. Another key aspect is the question of how AI can form synergies with humans to improve decision-making in complex situations in supply chain management and sustainably enhance cross-process data competence of humans.

The goal of this project proposal is the development of an AI-based system for the semantic classification and tagging of all documents generated and accumulated during a construction project. These documents, including plans, will be aggregated into clusters and visualized according to their themes. By eliminating the need for manual categorization, tagging, and clustering of information, the error rate is significantly reduced, and efficiency is enhanced.

The Smart Cities model projects are aimed at supporting municipalities by enabling the strategic use of digitalization for integrated and sustainable urban development. The objective of this funding program is to develop and test cross-sector digital strategies for the city of the future. Mannheim is one of 73 cities that have convinced the Federal Ministry of Housing, Urban Development, and Building with the project proposal “sMArt roots.”
The focal point of the sMArt roots project is an agile process for the development and implementation of a validated and interconnected Smart City strategy for Mannheim. The project is divided into two phases: Phase A : Development of the Smart City strategy for Mannheim. Phase B: Model implementation of the developed Smart City measures.

Consequences of AI for Urban Societies (CAIUS) is a joint research project by Ludwig Maximilian University Munich, University of Mannheim, and Hochschule Mannheim. CAIUS will help to identify unintended effects of AI systems in smart city contexts. AI systems help to efficiently allocate scarce public resources and are at the core of many smart city activities. Yet, the same systems may also result in unintended societal consequences, particularly by reinforcing social inequalities. CAIUS will identify and analyze such consequences.

Nowadays there is a growing trend in many scientific disciplines to support researchers by providing enhanced information access through linking of publications and underlying datasets. Open Science encourages scientific practices in which all research data is interlinked and contextualized to enhance reproducibility and reusability of research results. However, in practice, standards for referencing between primary text and the cited data and its variables are often missing. The goal of the VADIS project is to enable researchers to search for survey variables in context and thereby help to increase the reproducibility of research results.
We achieve this by combining text mining techniques and semantic web technologies that identify and exploit links between publications, their topics, and the specific variables that are covered in the surveys. These semantic links in scientific texts build the basis for the development of applications to give users better access to scientific literature such as passage search, summarization, and information retrieval.

This project explores how the framing of entities in political text is being used to deliver ideological messages. We investigate how we can automatically acquire machine-readable and human-interpretable representations of ideological framing that capture overt and latent similarities across political actors. Our approach brings together ideas from the Narrative Policy Framework, Moral Foundations Theory and frame-semantic parsing. Specifically, we model ideological framing, based on entity-centric and topic-specific ideological frames, their participants and latent moral values. We then use our representations to investigate research questions focusing on frame and ideology coherence as well as the evolution of frames over time, based on a series of highly relevant case studies of contemporary German party politics.

The rise of populism in Europe and throughout the world has been noted not only in politics and the media but has also been subject of many studies in political science and related areas. The concept of populism, however, is rather complex and vague and eludes strict definition. Therefore, we aim at laying the grounds for developing robust and reliable measures of populism, by combining insights from political science with quantitative text analysis and state-of-the-art Natural Language Processing (NLP) methodologies. To achieve this, we use information extraction techniques to identify the core protagonistis of populist rhetoric, i.e., mentions of the people (such as: Germans, tax payers, Muslims, Gabi Mustermann, etc.) and the elite (e.g., government, media, private sector, EU, politicians, intellectuals, ...). We then apply supervised machine learning techniques to disambiguate these mentions in context, leveraging additional information on subjective expressions and moral values, to model the concept of moralized politics. Aggregating over these informational dimensions will allow us to quantify the degree of populism for different speakers, parties, or media outlets.

This project addresses the challenge of providing up-to-date embeddings for dynamic knowledge graphs (KGs) and ontologies. The goal is to develop a framework capable of periodically collecting new KG versions, computing embeddings and making them publicly available for further research.
The aim of the LAVA research project led by Prof. Dr. Heiko Paulheim is to automatically create and improve knowledge graphs that are built into AI. The project is conducted in collaboration with the Karlsruhe-based company medicalvalues GmbH, with whom the group has already been cooperating since 2023 in a project for the AI-based detection of diabetes. Medicalvalues specializes in AI solutions for medical diagnostics in laboratories and clinics. In that domain, it is essential that the AI used is reliable and trustworthy. The aim of the project is to provide reusable, well-documented components for white box AI. White-box AI refers to models that make it transparent how decisions are made – for example, by using knowledge graphs that are also understandable for humans. Users can therefore understand what data a decision is based on – unlike with black-box models such as Chat GPT, where it is not possible to understand the answers.
The goal of the KI-DiabetesDetektion project is to integrate indication data from various sources in a knowledge graph and apply machine learning methods to improve the early stage detection of Diabetes.
In this project, we analyze the prevalence of hate speech on German Twitter using techniques such as natural language processing and network analysis. We will analyze and quantify the effect of the German Network Enforcement Act (NetzDG) on hate speech on Twitter, as well as consider recent changes, such as the takeover of Twitter by Elon Musk.
