text: "Classical machine learning techniques often struggle with overfitting and
unreliable predictions when exposed to novel conditions. 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."

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.

text: Recommendation systems are essential for delivering personalized content across
e-commerce and streaming services. 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. To enhance reproducibility, we release the
source code under https://github. com/HayaHalimeh/LLMs-For-Next-Item-Recommendation.git.

text: 'Data spaces have become a strategic pillar of Europe''s digital agenda, enabling
sovereign, legally compliant data sharing within decentralized ecosystems. 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.'

text: Adopting Large language models (LLMs) in organizations potentially revolutionizes
our lives and work. 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.

text: Optimal decision making requires appropriate evaluation of advice. Recent
literature reports that algorithm aversion reduces the effectiveness of predictive
algorithms. However, it remains unclear how people recover from bad advice given
by an otherwise good advisor. Previous work has focused on algorithm aversion
at a single time point. We extend this work by examining successive decisions
in a time series forecasting task using an online between-subjects experiment
(N = 87). Our empirical results do not confirm algorithm aversion immediately
after bad advice. The estimated effect suggests an increasing algorithm appreciation
over time. Our work extends the current knowledge on algorithm aversion with insights
into how weight on advice is adjusted over consecutive tasks. Since most forecasting
tasks are not one-off decisions, this also has implications for practitioners.

text: Many researchers and practitioners see artificial intelligence as a game changer
compared to classical statistical models. 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.

text: Despite the widespread use of machine learning algorithms, their effectiveness
is limited by a phenomenon known as algorithm aversion. 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.

text: 'Recommender systems now span the entire customer journey. 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.'

text: Clinical depression is a serious mental disorder that poses challenges for
both personal and public health. Millions of people struggle with depression each
year, but for many, the disorder goes undiagnosed or untreated. Over the last
decade, early depression detection on social media emerged as an interdisciplinary
research field. However, there is still a gap in detecting hesitant, depression-susceptible
individuals with minimal direct depressive signals at an early stage. We, therefore,
take up this open point and leverage posts from Reddit to fill the addressed gap.
Our results demonstrate the potential of contemporary Transformer architectures
in yielding promising predictive capabilities for mental health research. Furthermore,
we investigate the model’s interpretability using a surrogate and a topic modeling
approach. Based on our findings, we consider this work as a further step towards
developing a better understanding of mental eHealth and hope that our results
can support the development of future technologies.

text: The humanitarian crisis resulting from the Russian invasion of Ukraine has
led to millions of displaced individuals across Europe. Addressing the evolving
needs of these refugees is crucial for hosting countries and humanitarian organizations.
This study leverages social media analytics to supplement traditional surveys,
providing real-time insights into refugee needs by analyzing over two million
messages from Telegram, a vital platform for Ukrainian refugees in Germany. We
employ Natural Language Processing techniques, including language identification,
sentiment analysis, and topic modeling, to identify well-defined topic clusters
such as housing, financial and legal assistance, language courses, job market
access, and medical needs. Our findings also reveal changes in topic occurrence
and nature over time. To support practitioners, we introduce an interactive web-based
dashboard for continuous analysis of refugee needs.

text: "Digital technologies have made the line of visibility more transparent, enabling
customers to get deeper insights into an organization’s core operations than ever
before. This creates new challenges for organizations trying to consistently deliver
high-quality customer experiences. In this paper we conduct an empirical analysis
of customers’ preferences and their willingness-to-pay for different degrees of
process transparency, using the example of digitally-enabled business-to-customer
delivery services. Applying conjoint analysis, we quantify customers’ preferences
and willingness-to-pay for different service attributes and levels. Our contributions
are two-fold: For research, we provide empirical measurements of customers’ preferences
and their willingness-to-pay for process transparency, suggesting that more is
not always better. Additionally, we provide a blueprint of how conjoint analysis
can be applied to study design decisions regarding changing an organization’s
digital line of visibility. For practice, our findings enable service managers
to make decisions about process transparency and establishing different levels
of service quality.\r\n"

text: Many applications are driven by Machine Learning (ML) today. While complex
ML models lead to an accurate prediction, their inner decision-making is obfuscated.
However, especially for high-stakes decisions, interpretability and explainability
of the model are necessary. Therefore, we develop a holistic interpretability
and explainability framework (HIEF) to objectively describe and evaluate an intelligent
system’s explainable AI (XAI) capacities. This guides data scientists to create
more transparent models. To evaluate our framework, we analyse 50 real estate
appraisal papers to ensure the robustness of HIEF. Additionally, we identify six
typical types of intelligent systems, so-called archetypes, which range from explanatory
to predictive, and demonstrate how researchers can use the framework to identify
blind-spot topics in their domain. Finally, regarding comprehensiveness, we used
a random sample of six intelligent systems and conducted an applicability check
to provide external validity.
