Title: Towards controlled and sustainable AI in Model-Driven Development: Guard Rails based on Normalized Systems Theory
Abstract: Normalized Systems theory uses concepts such as stability from systems theory to study the evolvability of modular structures. Its focus is on eliminating so-called combinatorial effects from modular structures, which are ripple effects whose number of impacts is related to the size of the modular structure, which makes them highly undesirable from the point of view of controlled and sustainable evolution of for example, software architectures. To build Normalized Systems in practice, fine-grained skeletons of modular structures are generated and continuously re-generated over time by code generators implementing the principles of Normalized Systems Theory and Model-Driven Development. This approach is very well suited as a complement to the use of AI and LLMs for code generation, as the skeletons can be easily extended with micro-doses of AI-generated code, while at the same time
providing guard rails for the use of AI. These guard rails add traceability and control not only to the code generation process (which are currently seen as major limitations of LLM-based code generation), but also to the continuous re-generation of AI-generated software architectures over time.
| 10:00 | Detector-Anchored SAM2 for Trajectory-Consistent Multi-Object Tracking in Broadcast Soccer ABSTRACT. Multi-object tracking in broadcast soccer is difficult because occlusions, scale changes, and crowded interactions frequently disrupt identity continuity. This paper proposes a detector-anchored SAM2 policy that periodically re-aligns propagated tracks with detector outputs to improve trajectory consistency. We benchmark six detector-tracker combinations on SoccerNet-Tracking by pairing two RF-DETR variants with ByteTrack, BoT-SORT, and SAM2, all evaluated under a common protocol. On the full 49-sequence test split, RF-DETR Base + detector-anchored SAM2 achieves the best HOTA (0.512) and IDF1 (0.614) among the tested variants, while classical trackers retain substantially higher throughput. The results show that detector-anchored segmentation-assisted tracking is a strong option for offline tactical analysis where trajectory continuity matters more than runtime. |
| 10:15 | Protocol for Detecting Synthetic Artifacts: A Case Study on UXO Sonar Imagery ABSTRACT. Deep-learning pipelines for sonar-based UXO classification increasingly rely on synthetic data generated in Digital Twin environments. While such pipelines support scalable development of AI-enabled decision-support services, they also risk introducing hidden information leakage, causing models to learn non-physical shortcuts instead of target-relevant acoustic cues. In this paper, we consider a binary classification task (UXO vs.\ non-UXO) and present a five-stage protocol for auditing the integrity of synthetic sonar datasets before further model development and deployment. The protocol combines complexity stress-testing, saliency/Grad-CAM inspection, object masking, and bias-only training on masked images. In our case study, it revealed contamination linked to the simulator data-generation procedure. A leaky dataset achieved near-perfect balanced accuracy (up to 99.22\%), whereas the corrected dataset produced lower but more plausible results (97.35\% on an idealized seabed and 83.62\% on a realistic seabed). The protocol can therefore serve as a practical quality-assurance component for synthetic-data pipelines. |
| 10:30 | Task-Aligned Methodology for Handling Missing Data in Decision Support Systems: Workflow and Energy Case Study PRESENTER: Jarosław Kobiela ABSTRACT. This paper proposes a structured, integrative, and auditable methodology for managing missing values in decision support systems (DSS) to improve forecasting reliability. It advocates a shift away from black-box imputation toward a structured workflow that integrates data preprocessing, duplicate detection, multi-faceted missingness analysis, multicriteria selection of imputation strategies, and hold-out evaluation using the same forecast metric optimized by the DSS. The workflow is validated through an extensive study of 172 residential electricity consumption time series. The results demonstrate that formal missingness analysis is essential, as non-random missing patterns identified in all tested series preclude the use of biased, simplistic models. On this single dataset, simpler task-aligned imputation methods outperformed Stable Diffusion 2 generative inpainting by more than 25 percentage points in symmetric mean absolute percentage error (sMAPE), which is a cautionary observation rather than a general recommendation. By providing a clear and transparent path from raw data to validated forecasts, the proposed approach might enhance DSS robustness to missing data. |
| 10:45 | Developing a Diagnostic Information System for Hydraulic Piston Pumps: A Comparative Analysis of Anomaly Detection Methods ABSTRACT. The goal of the research is the analysis of the usability of unsupervised anomaly detection (AD) methods for detection of valve plate failures in piston pumps. The unsupervised AD methods play a special role in predictive maintenance since they do not require failure data to be present during training, which represents a typical scenario of real-world manufacturing operations where faulty states are rarely recorded. A comprehensive comparative analysis of nine detection algorithms, including deep learning models, was conducted using real-world process data. The results assess the models' effectiveness and resilience to industrial noise, identifying optimal solutions for increasing the reliability of monitoring systems in the era of Industry 4.0. The best average result AUC=0.9150 was obtained by the AutoEncoder. The results show that the Isolation Forest model significantly differs from Local Outlier Factor and One-Class SVM in terms of feature importance. Four techniques stand out for their results. |
| 10:00 | A Unified Transdisciplinary Framework of Best Practice Guidelines for Domain Engineering and Classification Dictionary Construction ABSTRACT. Domain models have a myriad of uses, including analysis, requirement specification, aiding decision-making processes, facilitating shared understanding between stakeholders, and other applications. However, existing approaches and methodological guidelines for building such models are often either non-existent, isolated, ad hoc, incomplete, or only address specific parts of the domain modeling process rather than the whole endeavour. All of this has raised concerns about the validity, quality, and utility of domain models produced by such approaches, and the maturity of the domain modeling field as a whole. This study helps to address these issues by proposing a novel hybrid theory- and data-driven domain modeling framework that integrates taxonomy construction and computer-aided text analytics to develop practitioner-oriented classification dictionaries. The proposed methodological framework extends and improves upon seven existing guidelines from multiple fields by unifying them into a single, holistic, systematic, and generalizable approach. The proposed framework achieved 13.5/16 in a quality evaluation and was successfully applied to build a large-scale classification dictionary for the video game development domain. These results demonstrate the capability of the new approach to construct high-quality dual-purpose ontological and analytical models in complex domains. |
| 10:20 | Identifying Reusable Metadata Candidates in Property Graph Schemas: A 5GNF-Oriented Design Method PRESENTER: Yahya Sa'D ABSTRACT. Property-graph schemas often contain descriptive properties that recur across heterogeneous nodes and edges. Some are ordinary local attributes, while others behave as reusable metadata that may be externalized as shared structures. However, property-graph schema design lacks an explicit 5GNF-oriented method for deciding when a repeated property should become a reusable metadata candidate. This paper proposes a rule-based design method for identifying such candidates before trait-node externalization. The method evaluates five criteria: cross-element occurrence, conceptual independence, lossless externalization, reuse potential, and governance relevance. Based on these criteria, properties are classified as trait candidates, embedded properties, or borderline cases. The method is illustrated using a library-domain example and evaluated across two schema contexts. The validation combines eight human and four LLM-based responses and examines classification distributions, agreement, and comparison with a recurrence-based baseline. Results indicate that repetition alone is insufficient for externalization. Clear embedded properties and reusable descriptors achieve stronger agreement, whereas semantically ambiguous properties remain context-dependent. The method therefore provides an explainable basis for identifying reusable metadata candidates before 5GNF-oriented normalization. |
| 10:35 | SmartPortBPMN: Modelling Smart and Green Logistics Operations in Ports ABSTRACT. Digital Transformation is driving significant changes in the port sector. Smart ports emerge as a response to these needs, integrating information technologies to optimise operations and minimise environmental impacts. Consequently, ports must deploy business process management mechanisms to coordinate and optimise workflows, enhance decision-making, and address the needs of the distinct stakeholders. We conducted a Design Science Research (DSR) project to develop, demonstrate, and evaluate a BPMN extension for smart and green logistics operations in ports. We collaborated with a port management entity to implement an innovative road entry terminal. Our extension incorporates elements that model (1) privacy, (2) energy efficiency, (3) risks, (4) data operations, and (5) domain-specific operations. The results are relevant to port business process modelling, as the developed extension aligns with the sector’s operational and logistical needs. |

| 11:30 | Transformer-Enhanced Hybrid Sampling for Synthetic Data Generation in Imbalanced Network Security Datasets ABSTRACT. The growing importance of cybersecurity, particularly in network environments, necessitates advanced incident detection systems. Machine learning-based classification algorithms are crucial for identifying security breaches within network traffic. However, datasets representing this problem are typically highly imbalanced, which hinders the performance of standard classifiers. To address this issue, various oversampling techniques are commonly employed to increase the representation of the minority class, combined with an undersampling algorithm designed to refine the dataset by selecting the most informative minority class representations. This paper proposes extending this hybrid approach with a Transformer-based model. The effectiveness of the proposed approach is validated through computational experiments, demonstrating its potential for improving incident detection performance in imbalanced security scenarios. |
| 11:45 | Semantic Convergence of Differentiating Properties as a Quality Predictor for Stance Classification PRESENTER: Mateusz Gierszewski ABSTRACT. We propose a stance classification framework based on hierarchically organized Differentiating Properties (DPs) -- linguistic features capturing opposing semantic attributes that define the poles of discourse polarization. DPs are automatically extracted from corpora via a multi-stage LLM pipeline and paired into oppositional variants, forming a bipolar semantic space. A linear Support Vector Machine (SVM) classifier operating on grouped DP embeddings performs stance classification by projecting target texts onto the polarization axis defined by opposing DP poles. Spearman rank correlation (ρ) and cosine similarity between pole embeddings define semantic convergence, serving as geometric diagnostic tools for assessing DP quality prior to classification. Experiments on three polarized corpora across two embedding models show that both metrics reliably predict quality of classification, as higher values correspond to higher F1 scores, while replacing high-ρ convergent pairs with low-ρ divergent pairs leads to a systematic performance degradation of up to 17%. |
| 12:00 | What Actually Works in Ultra-Small sEMG Datasets? A Comprehensive Audit of Classical and Graph Models for Subject-Level Parkinson's Detection ABSTRACT. This paper does not aim to present a clinically ready Parkinson’s disease classifier. Instead, it rigorously examines what actually works in an extreme low-sample setting for bilateral, smoothed sEMG signals, using a dataset of only 9 subjects (5 Parkinson’s disease, 4 healthy controls; 18 full recordings, 122 segments). We audit classical subject-level baselines and multiple state-graph families under leakage-safe protocols, with seed-stability analysis, segment augmentation, paired tests, and a permutation sanity check. A key finding is that isolated strong graph-model results can be misleading: some frozen graph configurations achieved ROC–AUC of 1.0, yet did not remain stable across seed reruns, and the best-performing graph branch changed across audited subsets. After fixing an evaluation bug, a naive subject-level baseline reached only 0.55 ROC–AUC, whereas a leakage-safe nested sparse baseline (outer and inner LOSO, fold-wise feature selection, logistic regression) achieved 0.778 accuracy, 0.775 balanced accuracy, 0.800 F1, 0.550 MCC, and 0.900 ROC–AUC, using 5.89 features per fold on average. The contribution is methodological: in ultra-low-N settings, evaluation rigor and stability analysis determine what counts as a valid result. |
| 12:15 | Impact of Class Balancing on Coalition-Based Classification in Distributed Data Settings ABSTRACT. The growing availability of data distributed across multiple independent sources creates new challenges for classification tasks. Such datasets often differ not only in their representations but also in class proportions, which complicates the construction of a consistent global model. This work addresses these issues by extending the authors’ previously proposed distributed classification framework that combines conflict analysis, coalition formation, and rule induction. The novelty is achieved by introducing a class balancing stage performed locally on each dataset prior to the learning process. Six data-level balancing techniques are evaluated. Decision rules are generated using four rough set-based algorithms, and final decisions are determined by three strategies. Experiments are conducted on two datasets: Car Evaluation and Balance Scale. The proposed approach outperforms a baseline for Car Evaluation, while for Balance Scale its effectiveness depends on data fragmentation. Additionally, coalition analysis indicates that higher data distribution leads to larger coalition sizes. |
| 12:30 | Reusing a Multimodal LLaVA Model for Rapid Learning of Human Gaze Prediction ABSTRACT. Large multimodal models recently achieved impressive performance on a wide range of vision-language tasks, but training such models from scratch is computationally expensive and hardware demanding, which motivates fine-tuning and model‑reuse strategies. In this work, we present a practical example of reusing a pretrained image-text-to-text model (LLaVA) for predicting human gaze fixation heatmaps. Instead of instruction tuning with prompt and response pairs, we attach a gaze prediction model. In the presented method, we operate directly on the hidden representations of a frozen multimodal backbone that runs in a quantized configuration to reduce GPU memory and enable training on consumer-grade hardware. We also demonstrate that multimodal features can be effectively repurposed to map internal states to human gaze fixation from the LLaVA model, which was originally developed for text generation, after a relatively brief training period. |
| 12:45 | Multimodal Neural Network with Time Series and Aggregated Feature Fusion for Electricity Consumption Optimization ABSTRACT. Effective electricity management on the consumer side is a key element in optimizing power system operation, particularly given the increasing share of renewable energy sources. Non-intrusive load monitoring (NILM) plays a crucial role by enabling detailed insight into energy consumption patterns. The obtained results enable load profile optimization by eliminating unnecessary consumption and shifting demand to off-peak periods and periods of high renewable generation. This paper presents a NILM system designed for real-world conditions characterized by the simultaneous operation of multiple devices and the presence of signal disturbances. The proposed approach is based on the synergistic use of steady-state and transient features, which serve as inputs to a multimodal deep neural network. The proposed method achieved an accuracy of 93.7%, confirming the effectiveness of multimodal feature fusion. |
| 14:00 | Do Large Language Models Change How Developers Seek Help? A Learning Trace-Based Study of Stack Overflow Behavior PRESENTER: Donatien Yeto ABSTRACT. The rapid integration of Large Language Models (LLMs) is transforming how developers search for information and solve technical problems. While these tools offer powerful support, they may also encourage cognitive offloading, potentially affecting independent problem-solving. This study examines whether LLM adoption relates to changes in troubleshooting traces in Stack Overflow questions. Drawing on cognitive offloading, transactive memory theory, and SRL, we analyze help-seeking behavior before (2019–2021) and after (2023–2025) widespread LLM adoption. Using machine learning–assisted annotation, we develop a Learning Trace Index (LTI) to capture observable problem-solving processes. Results show a sharp decline in platform activity after 2023, but only modest differences in troubleshooting traces across periods and experience levels. These findings offer empirical insight into cognitive offloading and introduce a scalable measure for studying learning behaviors in developer communities. |
| 14:15 | Actor-Network Theory Analysis of When LLMs Can and Cannot Be Enrolled ABSTRACT. Healthcare organisations face a critical gap in AI evaluation: accuracy benchmarks do not indicate whether systems will function reliably within the constraints of real clinical environments. This study addresses that gap with two contributions. First, it introduces the enrollability framework, four Information Systems-level criteria, grounded in Actor-Network Theory, that define when a Natural Language Processing (NLP) method can be stabilised as a clinical infrastructure. Second, it examines how Large Language Models (LLMs) align with these requirements in a non-English clinical NLP setting. While rule-based systems encode stable inscriptions compatible with network expectations, LLMs rely on next-token prediction that mimics but does not ensure such stability. We empirically compare rule-based and LLM-based approaches (Llama-3-8B-it, Gemma-7b-it) on 1,679 Polish paediatric epicrises. Findings reveal that accuracy and enrollability yield divergent evaluations, and suggest that common LLM failures (e.g., hallucinations, inter-physician variability, and notation mismatch) may be associated with properties of their generative mechanism, beyond capability limits. |
| 14:30 | Integrating Sustainability into a Software Quality Assessment: An Educational Study ABSTRACT. Integrating sustainability into software engineering education is essential for preparing future professionals for digital transformation. This paper presents a study with a pre-post design that evaluates the impact of embedding sustainability within a software quality assurance assignment in an undergraduate course. Results show an improvement in students' understanding, shifting their perspective from a technical to a more holistic, multi-dimensional view of sustainability. The intervention increased their confidence in interpreting sustainability metrics and enhanced practical skills, although challenges related to the adoption and use of sustainability metrics persist. |
| 14:45 | Determinants of Acceptance of Agentic AI: Integrating Traditional and Agentic Perspectives ABSTRACT. The study investigates the determinants of individual acceptance of agentic AI by integrating traditional technology acceptance constructs with agency-related characteristics of AI agents. While classical models such as UTAUT have been validated for traditional IT systems, emerging agentic AI, due to its autonomous performance and decision-making, requires a different theoretical lens. We develop and test an extended acceptance model incorporating perceived competence, decision autonomy, and performance autonomy alongside traditional determinants. A quantitative survey of AI users was conducted, and the collected data were analyzed using PLS‑SEM. The results demonstrate that all three agentic characteristics significantly shape performance expectancy, which, together with facilitating conditions and social influence, predicts intention to use AI agents. The findings highlight the need to reconceptualize acceptance frameworks for increasingly autonomous AI systems. |
| 15:00 | Leadership 5.0 and Human-Machine Collaboration for Sustainable Pharmaceutical Innovation ABSTRACT. The pharmaceutical industry is facing a significant transformation with the emergence of Industry 5.0, shifting its focus towards human-centeredness and sustainability. The right leadership approach is crucial for the successful implementation of this transformation. This exploratory study examines the approaches needed in the context of Leadership 5.0 adoption and its role in advancing human-machine collaboration and sustainable innovation in the pharmaceutical industry. By presenting a network analysis of the scientific literature, it maps the position of the Leadership 5.0 concept in the literature, its relationships with other concepts, and identifies research gaps. The analysis, based on a systematic review of 40 articles from Scopus and Web of Science, shows that research on Leadership 5.0 in the pharmaceutical industry is still in its early stages. This exploratory study lays the groundwork for future empirical research and may support managers and academics in understanding Leadership 5.0 adoption. |
| 15:15 | Determinants of Cloud Business Intelligence Implementation: An MCA and Cluster Analysis Approach ABSTRACT. The aim of this article is to identify patterns of co-occurrence in assessments regarding implementation determinants, benefits, barriers, post-implementation changes, and organizational outcomes associated with the use of Cloud Business Intelligence (CBI), as well as to identify enterprise segments with similar perceptions of these phenomena. The study was based on data obtained from 400 enterprises using cloud-based business analytics solutions. The analysis employed an exploratory approach, combining Multivariate Correspondence Analysis (MCA) with Ward's hierarchical cluster analysis. The results indicate that perceptions of CBI implementation have a multidimensional, non-random structure, and respondents' responses form distinct patterns that differentiate organizations in terms of the observability of benefits, the level of perceived implementation effectiveness, and the exposure to barriers. Based on this, five enterprise segments were identified, differing not only in their assessment of implementation outcomes but also in their organizational, technological, and decision-making profiles. |
| 15:30 | A Simulation and Fuzzy AHP-Based Analysis of Software Development Impact on Risk and Efficiency in GRC Processes ABSTRACT. Governance Risk and Compliance (GRC) activities are conducted by employees with high educated staff. The assets to be audited undergo control activities that are carried out by focusing on the areas to be audited within the audition space. In order to reach the analysis results of the AS-IS and TO-BE (new) process models with simulation, the effort estimates of these processes were obtained with the fuzzy AHP. Accordingly, it has been determined that information technology (IT) solutions with software developments to be used in audit activities can increase the completion time efficiency by 51.7%. In addition, it has been obtained that the workload of human resources decreased from 61% to 49%. The average risk occurrence probability of 5.85% has been reduced to 3.90%. The monetary loss of risks could be reduced 30.54%. In the creation of the new Audit Execution Process, the simulation of the AS-IS process is an indicator of the originality of this study. |
| 14:00 | A Digital Twin Architecture for AI Infused Information Systems Development: Process Mining, Multimodal Evidence Extraction, and Interpretable Decision Models PRESENTER: Algirdas Laukaitis ABSTRACT. This paper presents a digital twin architecture that mirrors how real admission processes work and shows where AI can be safely introduced. The system reconstructs workflows from historical data and uses AI agents to analyze documents, video, and structural data. Instead of relying on black box LLM based predictions, the system uses simple decision trees at each step of the process. These models make decisions explicit and easy to audit. A state based orchestration layer connects AI outputs to clearly defined process stages and supports a transition from notebook based prototypes to enterprise systems. The key contribution of this work is a practical development approach for AI systems. Instead of building monolithic solutions, the business logic is decomposed into small AI agents implemented as executable notebooks that communicate through cloud storage. This prototype can then be automatically transformed into enterprise ready services using AI programming agents. The approach is evaluated on real applications from a university admission process. Results show that the digital twin closely reproduces historical decisions while remaining interpretable. This work addresses the challenge of deploying AI in high stakes systems where both performance and explainability are required. |
| 14:20 | Fuzzy ICRA: Iterative Compromise Ranking under Uncertainty for Decision Support Systems ABSTRACT. Decision support systems embedded in modern information systems often rely on multi-criteria decision analysis (MCDA) to evaluate alternatives; however, selecting an appropriate MCDA method and managing imprecision in stakeholder assessments remain persistent challenges. The Iterative Compromise Ranking Analysis (ICRA) addresses the former by compromising rankings from multiple MCDA methods, but its original formulation assumes crisp inputs. This paper extends ICRA to operate on triangular fuzzy numbers (TFNs), enabling the processing of imprecise expert evaluations under uncertainty. The proposed Fuzzy ICRA applies alpha-cut arithmetic to propagate uncertainty through the MCDA methods at each iteration, preserving the informational content of fuzzy inputs throughout the compromise process. A simulation study with three experiments examines the method using TOPSIS and VIKOR. A step-by-step example demonstrates convergence and uncertainty evolution; a propagation analysis across six spread levels shows that ICRA reduces input uncertainty over iterations; and a robustness analysis evaluates sensitivity to expert-assessment noise. Results indicate reliable convergence and a consistent uncertainty-reduction effect, with TFN spreads decreasing monotonically after the second iteration. |
| 14:40 | Designing Preference-Aware Counterfactual Explanations for Adaptive Information Systems ABSTRACT. We propose a novel preference-based method for generating counterfactual explanations in AI-powered information systems that explicitly accounts for individual user preferences. To the best of our knowledge, our method is the first preference-based counterfactual generator in this area. We have conducted experiments on three popular datasets (Communities and Crime, German Credit, and Default of Credit Card Clients) with continuous attributes and binary labels. For those experiments, our method is feasible and capable of producing more relevant counterfactuals than other methods. In the given settings, it is also superior in terms of computational efficiency. In all cases we examined, our method outperformed other techniques in terms of preference alignment. These findings demonstrate the potential of preference-aware counterfactual explanation generation to enhance the adaptability and relevance of intelligent information systems, especially in the context of the sustainable integration of AI and automation. |
| 15:00 | Improving decision-makers' preference representation in decision support systems through an extended Fuzzy Ranking Comparison method ABSTRACT. An accurate representation of decision-maker preferences is a critical requirement for modern information systems and decision support systems, particularly in environments characterized by uncertainty. To address this challenge, this study proposes an extension of the Fuzzy Ranking Comparison (RANCOM) method by introducing alternative relationship functions and a controllable uncertainty parameter $\gamma$, enabling more flexible modeling of subjective judgments. A simulation-based analysis was conducted to evaluate the impact of different relationship functions on the accuracy of representing fuzzy criteria weights using multiple performance metrics. The results show that the logistic function consistently achieves the lowest TFN distance and the highest TFN similarity across most configurations, indicating the most accurate reconstruction of the reference preference structure. Additionally, the ratio-based and exponential functions outperform the standard three-value scheme, particularly for smaller problem sizes. These improvements enhance the ability of decision support systems to operate under uncertainty, leading to better alignment with user preferences and more reliable decision outcomes. The findings highlight the potential of the extended Fuzzy RANCOM method as an effective component of advanced information systems. |
| 15:20 | Mask-Conditioned Generative Reconstruction of Vascular Angiography as Forensic Obfuscation ABSTRACT. While Coronary Angiography is essential for AI diagnostics, ensuring data privacy within healthcare Information Systems remains challenging, as conventional anonymization fails to eliminate hardware-specific forensic signatures. Addressing the problem of how to balance strict privacy with downstream diagnostic utility, we propose a novel obfuscation pipeline. Instead of traditional image editing, we synthesize angiograms derived solely from binary vessel masks. This removes forensic artifacts while retaining the vascular structures vital for clinical diagnosis. We evaluate this against an Attribute Inference Attack identifying institutional data sources, comparing Pix2Pix and Diffusion architectures against classic augmentations. The proposed methods drop attack success from $F1=0.8$ to $F1\approx 0.3$ while maintaining binary segmentation $F1\approx 0.64$ (Pix2pix) and $\approx 0.79$ (Diffusion). Results demonstrate that mask-conditioned reconstruction significantly reduces the risk of source attribution, offering a means of anonymized medical data sharing across inter-organisational IS without a significant diagnostic utility trade-off. |
| 15:40 | Association Rules of Author Keywords for Thematic Mapping in Systematic Literature Reviews PRESENTER: Sebastian Matysik ABSTRACT. Systematic literature reviews (SLRs) commonly use keyword co-occurrence analysis for thematic mapping, but standard tools (e.g., VOSviewer, Bibliometrix) are limited to symmetric pairwise relationships. The aim of this study is to formalize author keyword association rule extracting (ARM) as a repeatable, complementary method for thematic mapping in SLR and to evaluate its analytical value relative to standard co-occurrence methods. We apply the Apriori algorithm to author keywords from Scopus and demonstrate it on two datasets: a medium one (597 publications on CSR and consumer behavior) and a large one (14,302 publications on gamification and marketing). Comparing ARM results with VOSviewer co-occurrence maps, we find ARM reveals directional dependencies and multi-item themes that symmetric analyses miss. We propose a three-step framework to incorporate ARM into the PRISMA synthesis stage and discuss using ARM-derived themes for embedding-based screening in EmbedSLR. |
