Effective resource allocation is crucial for optimizing business processes. Yet, most existing methods focus solely on single-process optimization, overlooking the interdependencies present in multi-process environments. This limitation results in inefficient resource allocation, and scalability challenges. To address this gap, we propose MuProMAC (Multi-Process Multi-Agent Coordination), a novel reinforcement learning-based method designed to optimize resource allocation across multiple interdependent business processes. Unlike prior methods, MuProMAC is the first online resource allocation method that explicitly models the interdependencies between processes and dynamically balances competing resource demands to minimize global average cycle time. We evaluate our method in five multi-process scenarios with different levels of resource contention, comparing it against state-of-the-art online resource allocation methods and three simple baselines. Our results show that MuProMAC is consistently among the top-performing methods in shared-resource environments. It achieves low cycle times and stable performance across different workload conditions, outperforming existing methods through its strong adaptability to evolving business processes and increasing complexity.

Large language models (LLMs) have demonstrated impressive proficiency in multilingual natural language processing (NLP), yet they frequently struggle with cultural commonsense—the implicit knowledge shaped by societal norms, traditions, and shared experiences. As these models are deployed in diverse linguistic and cultural settings, their ability to understand and apply cultural commonsense becomes crucial for ensuring fairness, inclusivity, and contextual accuracy. This paper presents a systematic review and a large-scale empirical benchmark for evaluating cultural commonsense in multilingual LLMs. Through a comprehensive evaluation of 15 models on the BLEnD dataset, our analysis reveals a critical performance gap of 64.2% between high-resource and low-resource cultures. The results demonstrate significant disparities across model architectures: encoder-only models show more consistent but lower overall performance compared to decoder-based models. We identify key limitations, including data scarcity, representational bias, and inadequate cross-lingual knowledge transfer. Finally, we propose future research directions, such as culturally diverse dataset curation, hybrid knowledge graph architectures, and fairness-aware fine-tuning. The primary contributions of this work are (1) a systematic review of challenges and mitigation strategies for cultural commonsense; (2) a large-scale empirical benchmark that evaluates 15 multilingual LLMs across 13 languages and 16 countries, revealing significant performance disparities; and (3) concrete findings on the effects of model architecture and the limitations of scale in cultural understanding. This research underscores the urgent need to advance cultural commonsense in multilingual LLMs to ensure the development of fair, inclusive, and contextually accurate AI systems globally.

Sequential recommendation faces critical challenges in handling data sparsity, noise interference, and ineffective intent modeling. To address these issues, this paper proposes a novel Intent-aware Pyramid Diffusion Recommendation Model (IPDRM) that integrates hierarchical intent modeling with conditional diffusion-based augmentation. The framework employs a pyramid structure to capture multi-granular user intents (base-level item features, mid-level temporal patterns, and top-level semantic abstractions) and utilizes intent-conditioned diffusion to generate semantically consistent augmented views. Contrastive learning is then applied to align representations of original and augmented sequences. Extensive experiments on Tmall and Fliggy datasets demonstrate that IPDRM significantly outperforms state-of-the-art baselines, achieving improvements of up to 20.0 % in HR@5 and 22.5 % in NDCG@5. The model exhibits strong robustness in sparse and noisy scenarios, validated through comprehensive ablation studies and parameter sensitivity analyses. This work provides a effective solution for intent-aware sequential recommendation with both theoretical and practical contributions. The code for the paper is available at https://github.com/CLTCGUO/IPDRM.

Fixed-point iteration (FPI) is a crucially important technique at the foundation of many scientific and engineering fields, such as numerical analysis, dynamical systems, optimization, and machine learning. In these domains, algorithmic efficiency and stability is often assessed using the notion of convergence order, a quantity whose estimation has typically involved line fitting in log–log space, or finding the limit of an associated function on differences of sequence values. In this paper, we establish a precise equivalence between the convergence order of a fixed-point update function and the local intrinsic dimensionality (LID) of that function once its fixed point is translated to the origin. Building on this insight, we propose a unified framework for re-purposing existing distributional estimators of LID to estimate the convergence order. Of the LID estimators considered, we show that two, the MLE (Hill) estimator and a Bayesian estimator, have practical and convenient closed-form expressions. We further investigate how these estimators of convergence order can be enhanced using Aitken’s method for accelerating convergence in slow scenarios, as well as a Bayesian smoothing layer for reducing variance when the number of samples is small. Empirically, we benchmark our LID-based estimators against classical sequenced-based and curve-fitting methods in three experimental settings: root-finding, general iteration, and machine learning regression. Results indicate that our approaches frequently match or surpass the classical estimators in accuracy, while offering robust performance over a broader range of convergence scenarios.

In an increasingly digital world, collecting, processing, and exchanging personal data are critical drivers for enacting enterprise business processes. However, the long-term retention and access of personal data expose organizations to data breaches, in which sensitive and protected data are disclosed and exploited unauthorizedly. To mitigate the damage that data breaches can cause, in the European Union (EU), the right to data privacy is enforced through the General Data Protection Regulation (GDPR), which defines how organizations must store and manage EU citizens’ data. GDPR is highly influencing how organizations approach data privacy, forcing them to rethink and upgrade their business processes to become GDPR compliant, which can be daunting. In this paper, in line with the privacy-by-design principles of GDPR, we propose a methodology that shows how to capture the main privacy GDPR constraints in the form of design patterns and integrate them into business process models specified in BPMN (Business Process Model and Notation). This allows us to achieve full transparency of privacy constraints in business processes, making it possible to ensure their compliance with GDPR at design-time. We adopt a design science research approach to present our methodology and make design decisions explicit. We also introduce GDPR-Pilot, a BPMN editor that assists process designers and Data Controllers in integrating GDPR patterns into existing models. The methodology is evaluated through real-world use cases against structural, usage, and environmental requirements.

A recent surprising result in the implementation of worst-case-optimal (wco) multijoins in graph databases (specifically, basic graph patterns) is that they can be supported on graph representations that take even less space than a plain representation, and orders of magnitude less space than classical indices, while offering comparable performance. In this paper we uncover a wide set of new wco space–time tradeoffs: we (1) introduce new compact indices that handle multijoins in wco time, and (2) combine them with new query resolution strategies that offer better times in practice. As a result, we improve the average query times of current compact representations by a factor of up to 13 to produce the first 1000 results, and using twice their space, reduce their total average query time by a factor of 2. Our experiments suggest that there is more room for improvement in terms of generating better query plans for multijoins.

Autonomous decision-making systems, particularly recommender systems, have received increasing attention concerning fairness, i.e., if all stakeholders affected by such a system are treated equally as a result of the recommendations. Existing approaches primarily focus on fairness between two stakeholders – consumers and providers or consumers and items – treating providers and items as the same entity. However, we argue for the treatment of providers and items as distinct stakeholders to offer more comprehensive models of fairness in recommender systems. To this end, we propose a fairness-aware recommender system, CIPFRS, designed to optimize fairness across all three key stakeholders: consumers, providers, and items. We examine consumer fairness regarding their level of interaction with the system; high and low-activity users should be treated equally. Further, all providers should have an equal opportunity for their products to be recommended. Finally, we propose an approach to implement item fairness in each provider’s inventory. We report an extensive evaluation of the proposed solution through three datasets, demonstrating that considering all three stakeholders yields improved recommendations while minimizing bias.

This work is a companion reproducibility paper that presents a framework to reproduce our previous experiments and results reported in Liu et al. (2024). In that previous paper, we proposed an efficient visual exploration approach of geospatial vector big data on the web map, which designs the display-driven visualization model and combines the traditional data-driven visualization model to realize the interactive real-time map visualization. Due to the lack of reproducible and extensible implementations of methods, our work introduces a comprehensive reproducibility framework to publicly release our source code, datasets, runtime environment, experiments, and software tools. We provide detailed reproducibility protocols for both the experiments and the software tool. After downloading the dataset and deploying the environment setups, our primary work (Liu et al., 2024) can be successfully reproduced, and the on-site visual exploration for user-provided datasets on the web map can be demonstrated by running a series of execution scripts of the experiments and the software tool. The reproducibility protocol can be created and tested in both Ubuntu machines and Docker containers. Moreover, we introduce and discuss new experimental results by running the reproducibility protocol introduced herein, our work can be considered weakly reproducible, since we were able to validate the ability of our work to interact in real-time and outperform the existing methods, leading us to the same conclusions.
这项工作是一篇可重复性的论文,它提出了一个框架来重现我们之前的实验和Liu等人(2024)报告的结果。在之前的文章中,我们提出了一种高效的web地图地理空间矢量大数据可视化探索方法,设计了显示驱动的可视化模型,并结合传统的数据驱动可视化模型,实现交互式实时地图可视化。由于缺乏可复制和可扩展的方法实现,我们的工作引入了一个全面的可复制框架,以公开发布我们的源代码、数据集、运行时环境、实验和软件工具。我们为实验和软件工具提供了详细的再现性协议。下载数据集并部署环境设置后,我们的主要工作(Liu et al., 2024)可以成功复制,并且可以通过运行一系列实验的执行脚本和软件工具来演示web地图上用户提供的数据集的现场可视化探索。可重复性协议可以在Ubuntu机器和Docker容器中创建和测试。此外,我们通过运行本文介绍的可重复性协议引入并讨论了新的实验结果,我们的工作可以被认为是弱可重复性的,因为我们能够验证我们的工作实时交互的能力,并且优于现有的方法,从而导致我们得出相同的结论。

After downloading the dataset and deploying the environment setups, our primary work (Liu et al., 2024) can be successfully reproduced, and the on-site visual exploration for user-provided datasets on the web map can be demonstrated by running a series of execution scripts of the experiments and the software tool. The reproducibility protocol can be created and tested in both Ubuntu machines and Docker containers. Moreover, we introduce and discuss new experimental results by running the reproducibility protocol introduced herein, our work can be considered weakly reproducible, since we were able to validate the ability of our work to interact in real-time and outperform the existing methods, leading us to the same conclusions.</div></div>","PeriodicalId":50363,"journal":{"name":"Information Systems","volume":"137 ","pages":"Article 102640"},"PeriodicalIF":3.4,"publicationDate":"2025-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145571431","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
