However, traditional methods often fail in cold-start scenarios where new items lack prior interactions. Recent advances in large language models (LLMs) offer a promising alternative. In this paper, we adopt the retrieve-and-recommend framework and propose to fine-tune the LLM jointly on warm-and cold-start next-item recommendation tasks, thus, mitigating the need for separate models for both item types. We computationally compare zero-shot prompting, in-context learning, and fine-tuning using the same LLM backbone, and benchmark them against strong PLM-based baselines. Our findings provide practical insights into the trade-offs between accuracy and computational cost of these methods for next-item recommendation.

As data space initiatives evolve, personalized recommendations are increasingly recognized as key use cases. However, traditional recommendation approaches typically rely on centralized aggregation of user behavior data-directly conflicting with the core ethos of data spaces: sovereignty, privacy, and trust. Federated recommendation systems offer a promising alternative by training models locally and exchanging only intermediate parameters to build a global model. Despite this potential, the integration of federated recommendation techniques and data space architectures remains largely underexplored in research and practice. This paper addresses this gap by designing and evaluating a prototype of a federated recommendation system specifically tailored for data spaces and compliant with their underlying infrastructure. Our findings highlight the viability of developing privacy-preserving, collaborative recommendation systems within data spaces, and contribute to the broader adoption of AI across these emerging ecosystems.","lang":"eng"}]},{"date_updated":"2026-01-07T13:46:50Z","status":"public","title":"Towards Greener Choices: Decision Information Nudging for Sustainability-Aware Recommender Explanations","year":"2025","conference":{"name":" The Second International Workshop on Recommender Systems for Sustainability and Social Good, RecSoGood 2025","start_date":"2025-09-26","location":"Prague, Czech Republic"},"author":[{"id":"87673","last_name":"Halimeh","first_name":"Haya","full_name":"Halimeh, Haya"},{"id":"72849","last_name":"Müller","first_name":"Oliver","full_name":"Müller, Oliver"}],"doi":"10.1007/978-3-032-13342-7","user_id":"87673","main_file_link":[{"open_access":"1","url":"https://link.springer.com/book/10.1007/978-3-032-13342-7"}],"language":[{"iso":"eng"}],"_id":"63525","abstract":[{"lang":"eng","text":"Recommender systems (RS) can support sustainable development by steering users toward more sustainable choices.

Introducing causality into the modelling process offers a promising way to mitigate these challenges by enhancing predictive robustness. However, constructing an initial causal graph manually using domain knowledge is time-consuming, particularly in complex time series with numerous variables. To address this, causal discovery algorithms can provide a preliminary causal structure that domain experts can refine. This study investigates causal feature selection with domain knowledge using a data center system as an example. We use simulated time-series data to compare \r\ndifferent causal feature selection with traditional machine-learning feature selection methods. Our results show that predictions based on causal features are more robust compared to those derived from traditional methods. These findings underscore the potential of combining causal discovery algorithms with human expertise to improve machine learning applications."}],"language":[{"iso":"eng"}],"_id":"60680","main_file_link":[{"url":"https://aisel.aisnet.org/ecis2025/bus_analytics/bus_analytics/2/"}],"user_id":"72849","conference":{"start_date":"16.06.2025","name":"European Conference on Information Systems","location":"Amman, Jordan","end_date":"18.06.2025"},"author":[{"id":"105506","first_name":"David Ricardo","last_name":"Zapata Gonzalez","full_name":"Zapata Gonzalez, David Ricardo"},{"full_name":"Meyer, Marcel","first_name":"Marcel","last_name":"Meyer","id":"105120"},{"last_name":"Müller","first_name":"Oliver","full_name":"Müller, Oliver","id":"72849"}],"year":"2025","status":"public","title":"Bridging the gap between data-driven and theory-driven modelling – leveraging causal machine learning for integrative modelling of dynamical systems","date_updated":"2025-07-22T06:30:37Z"},{"department":[{"_id":"196"}],"keyword":["Process Mining","Large Language Model","Knowledge Management","Knowledge-Intensive Process","Tacit Knowledge"],"type":"conference","date_created":"2025-08-20T07:03:37Z","abstract":[{"text":"Large Language Models (LLMs) excel in understanding, generating, and processing human language, with growing adoption in process mining. Process mining relies on event logs that capture explicit process knowledge; however, knowledge-intensive processes (KIPs) in domains such as healthcare and product development depend on tacit knowledge, which is often absent from event logs. To bridge this gap, this study proposes a LLM-based framework for mobilizing tacit process knowledge and enriching event logs. A proof-of-concept is demonstrated using a KIP-specific LLM-driven conversational agent built on GPT-4o. The results indicate that LLMs can capture tacit process knowledge through targeted queries and systematically integrate it into event logs. This study presents a novel approach combining LLMs, knowledge management, and process mining, advancing the understanding and management of KIPs by enhancing knowledge accessibility and documentation.","lang":"eng"}],"related_material":{"link":[{"relation":"confirmation","url":"https://aisel.aisnet.org/amcis2025/sig_svc/sig_svc/11/"}]},"citation":{"short":"K.

At the same time, reusing waste heat from DCs also represents an opportunity, for example, for more sustainable heating of residential buildings. Modeling and optimizing these coupled and dynamic systems of heat generation and reuse is complex. On the one hand, physical simulations can be used to model these systems, but they are time-consuming to develop and run. Machine learning (ML), on the other hand, allows efficient data-driven modeling, but conventional correlation-based approaches struggle with the prediction of interventions and out-of-distribution generalization. Recent advances in causal ML, which combine principles from causal inference with flexible ML methods, are a promising approach for more robust predictions. Due to their focus on modeling interventions and cause-and-effect relationships, it is difficult to evaluate causal ML approaches rigorously. To address this challenge, we built a testbed of a miniature DC with an integrated waste heat network, equipped with sensors and actuators. This testbed allows conducting controlled experiments and automatic collection of realistic data, which can then be used to benchmark conventional and causal ML methods. Our experimental results highlight the strengths and weaknesses of each modeling approach, providing valuable insights on how to appropriately apply different types of machine learning to optimize data center operations and enhance their sustainability.","lang":"eng"}],"language":[{"iso":"eng"}],"main_file_link":[{"url":"https://dl.acm.org/doi/abs/10.1145/3757892.3757893","open_access":"1"}],"doi":"10.1145/3757892.3757893","author":[{"id":"105506","first_name":"David Ricardo","last_name":"Zapata Gonzalez","full_name":"Zapata Gonzalez, David Ricardo"},{"id":"105120","full_name":"Meyer, Marcel","last_name":"Meyer","first_name":"Marcel","orcid":" 0009-0005-9136-8525"},{"first_name":"Oliver","last_name":"Müller","full_name":"Müller, Oliver","id":"72849"}],"publication_identifier":{"issn":["2770-5331","2770-5331"]},"year":"2025","title":"Causal Machine Learning Approaches for Modelling Data Center Heat Recovery: A Physical Testbed Study","intvolume":"         5","date_updated":"2026-09-01T11:18:27Z","publication_status":"published","oa":"1","citation":{"chicago":"Zapata Gonzalez, David Ricardo, Marcel Meyer, and Oliver Müller. “Causal Machine Learning Approaches for Modelling Data Center Heat Recovery: A Physical Testbed Study.” In <i>ACM SIGEnergy Energy Informatics Review</i>, 5:4–10.

However, they can generate off-topic, discriminating, or harmful content. This AI alignment problem often stems from misspecifications during the LLM adoption, unnoticed by the principal due to the LLM’s black-box nature. While various research disciplines investigated AI alignment, they neither address the information asymmetries between organizational adopters and black-box LLM agents nor consider organizational AI adoption processes. Therefore, we propose LLM ATLAS (LLM Agency Theory-Led Alignment Strategy) a conceptual framework grounded in agency (contract) theory, to mitigate alignment problems during organizational LLM adoption. We conduct a conceptual literature analysis using the organizational LLM adoption phases and the agency theory as concepts. Our approach results in (1) providing an extended literature analysis process specific to AI alignment methods during organizational LLM adoption and (2) providing a first LLM alignment problem-solutionspace.","lang":"eng"}],"publication":"Wirtschaftsinformatik 2024 Proceedings","citation":{"mla":"Kaltenpoth, Sascha Benjamin, and Oliver Müller. “Getting in Contract with Large Language Models - An Agency Theory Perspective On Large Language Model Alignment.” <i>Wirtschaftsinformatik 2024 Proceedings</i>, 2024.","bibtex":"@inproceedings{Kaltenpoth_Müller_2024, title={Getting in Contract with Large Language Models - An Agency Theory Perspective On Large Language Model Alignment}, booktitle={Wirtschaftsinformatik 2024 Proceedings}, author={Kaltenpoth, Sascha Benjamin and Müller, Oliver}, year={2024} }","ama":"Kaltenpoth SB, Müller O.

However, some software providers engage in “AI washing”, relabeling solutions that use simple statistical models as AI systems. By contrast, research on algorithm aversion unsystematically varied the labels for advisors and treated labels such as \"artificial intelligence\" and \"statistical model\" synonymously. This study investigates the effect of individual labels on users' actual advice utilization behavior. Through two incentivized online within-subjects experiments on regression tasks, we find that labeling human advisors with labels that suggest higher expertise leads to an increase in advice-taking, even though the content of the advice remains the same. In contrast, our results do not suggest such an expert effect for advice-taking from algorithms, despite differences in self-reported perception. These findings challenge the effectiveness of framing intelligent systems as AI-based systems and have important implications for both research and practice.","lang":"eng"}]},{"main_file_link":[{"url":"https://aisel.aisnet.org/wi2023/19 "}],"language":[{"iso":"eng"}],"_id":"50118","user_id":"51271","status":"public","title":"The Broken Leg of Algorithm Appreciation: An Experimental Study on the Effect of Unobserved Variables on Advice Utilization","year":"2023","author":[{"id":"51271","last_name":"Leffrang","first_name":"Dirk","orcid":"0000-0001-9004-2391","full_name":"Leffrang, Dirk"}],"conference":{"location":"Paderborn","name":"Wirtschaftsinformatik"},"date_updated":"2024-01-10T09:53:24Z","date_created":"2024-01-03T09:50:06Z","keyword":["Algorithm aversion","Data","Decision-making","Advice-taking","Human-Computer Interaction"],"type":"conference","department":[{"_id":"196"}],"issue":"19","publication":"Wirtschaftsinformatik Conference","citation":{"apa":"Leffrang, D.

Recent research concluded that unobserved variables can cause algorithm aversion. However, the impact of an unobserved variable on algorithm aversion remains unclear. Previous studies focused on situations where humans had more variables available than algorithms. We extend this research by conducting an online experiment with 94 participants, systematically varying the number of observable variables to the advisor and the advisor type. Surprisingly, our results did not confirm that an unobserved variable had a negative effect on advice-taking. Instead, we found a positive impact in an algorithm appreciation scenario. This study provides new insights into the paradoxical behavior in which people weigh advice more despite having fewer variables, as they correct for the advisor's errors. Practitioners should consider this behavior when designing algorithms and account for user correction behavior.","lang":"eng"}]},{"_id":"50431","language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1","url":"https://scholar.google.com/citations?view_op=view_citation&hl=en&user=zBlrdP4AAAAJ&citation_for_view=zBlrdP4AAAAJ:UeHWp8X0CEIC"}],"user_id":"87673","conference":{"end_date":"2023-09-22","start_date":"2023-09-18","name":"Workshop on Recommenders in Tourism, co-located with the 17th ACM Conference on Recommender Systems"},"author":[{"id":"87673","last_name":"Halimeh","first_name":"Haya","full_name":"Halimeh, Haya"},{"last_name":"Freese","first_name":"Florian","full_name":"Freese, Florian"},{"id":"72849","full_name":"Müller, Oliver","first_name":"Oliver","last_name":"Müller"}],"status":"public","title":"Event Recommendations through the Lens of Vision and Language Foundation Models","year":"2023","date_updated":"2024-01-10T16:10:04Z","date_created":"2024-01-10T14:20:12Z","oa":"1","department":[{"_id":"195"},{"_id":"196"}],"type":"conference","citation":{"bibtex":"@inproceedings{Halimeh_Freese_Müller_2023, title={Event Recommendations through the Lens of Vision and Language Foundation Models}, booktitle={Workshop on Recommenders in Tourism, co-located with the 17th ACM Conference on Recommender Systems}, author={Halimeh, Haya and Freese, Florian and Müller, Oliver}, year={2023} }","chicago":"Halimeh, Haya, Florian Freese, and Oliver Müller. “Event Recommendations through the Lens of Vision and Language Foundation Models.” In <i>Workshop on Recommenders in Tourism, Co-Located with the 17th ACM Conference on Recommender Systems</i>, 2023.","ama":"Halimeh H, Freese F, Müller O.

Amid the multitude of diversified experi- ences, immersing in cultural events has become a key aspect of tourism. Cultural events, however, suffer from fleeting lifecycles, evade exact replication, and invariably lie in the future. In addition, their low standardization makes harnessing historical data regarding event content or past patron evaluations intricate. The distinctive traits of events thereby compound the challenge of the cold-start dilemma in event recommenders. Content-based recommendations stand as a viable avenue to alleviate this issue, functioning even in scenarios where item-user information is scarce. Still, the effectiveness of content- based recommendations often hinges on the quality of the data representation they build upon. In this study, we explore an array of cutting-edge uni- and multimodal vision and language foundation models (VL-FMs) for this purpose. Next, we derive content-based recommendations through a straightforward clustering approach that groups akin events together, and evaluate the efficacy of the models through a series of online user experiments across three dimensions: similarity-based evaluation, comparison-based evaluation, and clustering assignment evaluation. Our experiments generated four major findings. First, we found that all VL-FMs consistently outperformed a naive baseline of recommending randomly drawn events. Second, unimodal text-based embeddings were surprisingly on par or in some cases even superior to multimodal embeddings. Third, multimodal embeddings yielded arguably more fine-grained and diverse clusters in comparison to their unimodal counterparts. Finally, we could confirm that cross event interest is indeed reliant on the perceived similarity of events, resonating with the notion of similarity in content-based recommendations. All in all, we believe that leveraging the potential of contemporary FMs for content-based event recommendations would help address the cold-start problem and propel this field of research forward in new and exciting ways.","lang":"eng"}]},{"citation":{"ama":"Halimeh H, Caron M, Müller O.
