Forecasting Financial Distress for Shaping Public Policy: An Empirical InvestigationSoumya Ranjan Sethi, Dushyant Ashok MahadikActa Informatica Pragensia 2025, 14(1), 63-87 | DOI: 10.18267/j.aip.2536439 Background: Prediction of financial distress has been made more accurate and reliable through machine learning methods. Financial stress affects the business corporate entity, society and the general economy. Analysing such nonlinear events is essential for preventing the dangers and supporting a favourable economic climate. Objective: This paper seeks to develop a robust predictive model for identifying firms in the Indian context other than the financial service sector that may face financial distress and also to check the impact of one essential predictor, i.e., future cash flow, on financial distress prediction. Besides, the study also aims at making research that can inform public policy and provide recommendations. Methods: The study employs financial information from the Prowess Database but is confined to non-financial service sector firms in India. Logistic regression, linear discriminant analysis (LDA), and artificial neural networks (ANNs) are applied to predict financial distress and their ability to foretell future cash flows. Other methods adopted in evaluating the models include accuracy, sensitivity, and specificity. Results: ANNs outperform the other models based on accuracy and predictability, which are higher than the rates given by the other two models, namely logistic regression and LDA. The ANN model performs well in identifying financially distressed firms; thus, it is informative in evaluating their financial position. Also, results suggest that future cash flow substantially affects financial distress prediction, an essential new variable that needs to be considered in future research. Conclusion: This predictive model of financial distress further gives a sound platform for the corresponding sector in India. In general, ANNs offer profound opportunities for managers, investors, policymakers, regulators and shareholders as an effective tool for preventive decision-making to reinforce the corporate world. This research demonstrates that high-level machine-learning approaches are still crucial in financial analysis and policymaking. |

In addition, the outcome of our detailed study may aid researchers to carry out further research. |
The Process of Unit Price Extraction from Public Sector ContractsTomá¹ Bruckner, Filip VencovskýActa Informatica Pragensia 2020, 9(2), 170-183 | DOI: 10.18267/j.aip.1396619 Czech government institutions commissioned a research on extracting usual unit prices from public IT contracts to aid future public tender sizing. The goal of the project is to obtain millions of contracts from the public register, convert them to full text, extract unit prices from the text and publish a pricelist of IT industry manday prices. This paper designs the process and method of price extraction, demonstrates and evaluates the result on five iterations of extraction and discusses the experience of two years of project performance. The process is designed as a set of repeatable workflows and specified activity and role description. The method is designed as a combination of automated and manual actions. Due to the format and content variability of involved documents and the low mistake tolerance, the possibility of automated extraction of unit prices from full text contract is limited, and human workforce for validation is crucial. |

Artificial Intelligence in Software Testing and Beyond: A Review of Current Practices and Emerging ChallengesCodrina-Victoria Lisaru, Claudiu-Vasile KiforActa Informatica Pragensia 2026, 15(2), 514-546 | DOI: 10.18267/j.aip.3031341 Background: Artificial intelligence (AI) is increasingly used both to test software (T1) and to assure AI-based systems (T2), with adjacent software-engineering work that shapes testing practice (T3). Prior reviews are mostly descriptive and rarely report comparable maturity or replicability signals.Objective: To provide a PRISMA-style systematic review (2015–2025, Web of Science) that maps T1–T2–T3 within a testing-centric frame, audits evidence maturity, threats reporting, and artefact openness per paper, and adds an explicit lens of large language models or generative AI (LLMs/GenAI).Methods: We queried the Web of Science Core Collection (2015–2025), screened via a predefined protocol, and extracted ten items (D1–D10) per study to normalize comparisons. Seventy-two papers met the criteria. Findings are organized into three themes: (T1) AI-based software testing, (T2) testing/validation of AI systems, and (T3) AI-related software engineering topics with implications for testing—T3 corresponding to the “beyond” in the paper’s title.Results: The corpus is limited in practice-oriented evidence: 31 laboratory/simulation, 3 industrial, 10 hybrid, 6 conceptual/guideline and 22 secondary studies. Only 18/72 provide public artefacts; 33/72 report no empirical metrics. By theme, T1=32, T2=15, T3=25; the LLMs/GenAI subset totals 10 papers. Openness strongly co-occurs with measurable outcomes (88.9% of artefact-sharing papers report metrics vs 42.6% without), yet “all-three credible” studies (industrial/hybrid + open artefacts + metrics) are rare (4/72 overall; 1/10 for LLMs/GenAI).Conclusion: AI shows promise for testing, but evidence remains thin on industrial adoption and reproducibility. We recommend prioritizing hybrid/industrial validations, releasing artefacts by default, and using standardized task–metric bundles. The review presents T1 and T2 results, separates T3 for scope clarity, and provides actionable maturity and replicability signals to guide responsible, empirical adoption. |
Teachers' Perceptions of E-learning and Their Professional Competencies in the Béni Mellal-Khénifra Region in MoroccoEl Mustapha El anouar, Mohamed Jallal El adnani, Marouane Zouine, Mustapha El azzabiActa Informatica Pragensia 2025, 14(3), 408-421 | DOI: 10.18267/j.aip.2665542 Background: Recently, e-learning has emerged as a prominent tool for professional development in the education sector.Objective: The aim of this study was to examine teachers′ perceptions of improving their professional skills through e-learning in the Béni Mellal-Khénifra region of Morocco.Methods: The research utilized a questionnaire survey method to collect primary data from 518 teachers. The variables in the proposed model were assessed using a self-tailored five-point Likert scale. Data analysis was performed through confirmatory factor analysis and structural equation modelling using analysis of moment structures (AMOS).Results: The results indicate the impact of teachers′ satisfaction with their use of e-learning on the development of their professional competencies, without any direct effect of the actual use of e-learning on these skills. This suggests that satisfaction plays a mediating role between actual use and the development of teachers′ professional competencies. The study also found that overall quality significantly affects both user satisfaction and actual use by teachers within an online learning context.Conclusion: As a practical implication, stakeholders should focus on the technical, semantic and efficient features of e-learning to maximize the opportunity for better results among teachers in terms of developing both technical and non-technical skills. |
Knowledge-Based and Intelligent Engineering Trends in Smart Cities: A Bibliometric Analysis of Machine Learning ApplicationsRituraj Jain, Ashish Sharma, Nausheen Khilji, Ramesh Babu Putchanuthala, Venkateswararao Pulipati, Mysore KeshavaRao Harikeerthan, Himanshu GuptaActa Informatica Pragensia 2026, 15(1), 274-306 | DOI: 10.18267/j.aip.2982437 Background: Artificial intelligence (AI) and machine learning (ML) have become a revolutionary force in the development of smart cities and are changing the way cities are built, run and managed. With the rapid acceleration of the degree of urbanization and technological convergence, the state of research in this interdisciplinary area is a question that is very important for both researchers and policy makers.Objective: This study aims to present an all-round analysis of the smart city applications of ML, in terms of both bibliometric and thematic analysis. The focus is on identifying trends in publication, major contributors, emerging topics of research and methodological trends that define advances in this area.Methods: A total of 1960 peer-reviewed journal articles indexed in Scopus (excluding MDPI and Frontiers) from 2015 to April 2025 were analysed according to the PRISMA protocol in order to guarantee data accuracy and transparency. Python and VOSviewer tools were used to summarize and map the publication trends, institutional productivity, thematic clusters and the development of different levels of paradigms. To improve reliability, the same search criteria were used to extract a parallel dataset of 720 records from the Web of Science (WoS) Core Collection (excluding ESCI, MDPI and Frontiers). A cross-validation of publication patterns, thematic and disciplinary representation was conducted separately on the WoS dataset.Results: The analysis reveals a significant rise in research output after 2020, with China, India and Saudi Arabia leading the research output, which is consistent with national AI and urban digitization initiatives. The most-cited articles show a thematic shift from infrastructure-focused works such as IoT, smart grids and mobility systems towards more specifically ethically oriented works such as federated learning, climate resilience and algorithmic governance. A number of different methodologies such as deep learning, reinforcement learning and privacy-preserving AI models have been developed. Two of the four areas studies show a high level of agreement between Scopus and WoS but WoS is more prevalent in urban studies and planning and Scopus additionally encompasses engineering and computer science.Conclusion: In this regard, our findings demonstrate a clear convergence of ML with the domains of urban policy, sustainability and sociotechnical governance and a paradigm shift from technology-led to value-led innovation. This development corresponds to the increased transparency, inclusiveness and responsible use of AI in the field. The paper offers a validated and data-driven point of reference to researchers, practitioners and policy-makers so as to guide and affect the emerging frontiers of AI-enabled smart city transformation. |

In this context: (1) policymakers are responsible for establishing governance and regulations; (2) AI innovators must embed ethics into AI systems; (3) business leaders should establish ethical policies and guidelines; and (4) individuals need to think critically and use AI responsibly.Conclusion: The responsible deployment of AI requires a comprehensive approach that involves the collaboration of all relevant stakeholders. The future development of AI relies on the adoption of ethical guidelines and the assurance of responsible AI system design. |
Design and Usability Evaluation of LDSAM: An Aligned ISO/IEC 29110 – Basic Profile – Development Methodology for Big Data Software Systems in Small BusinessDavid Alejandro Montoya-Murillo, Manuel Mora, Gloria Phillips-Wren, Sergio Galván-Cruz, Estela Lizbeth Muñoz-AndradeActa Informatica Pragensia 2026, 15(2), 440-472 | DOI: 10.18267/j.aip.317578 Background: System Development Life Cycles (SDLC) are proposed through development methodologies (e.g. Rational Unified Process) and international standards (e.g. ISO/IEC 12207) to guide the systematic development of software products to meet expected time, budget, and functional quality. The ISO/IEC 29110-5-1-2: Software engineering guidelines for the generic Basic profile standard provides a disciplined-systematic lightweight SDLC alternative to agile approaches for businesses interested in ISO/IEC certifications rather than agile ones. However, its utilization in the domain of Big Data Analytics Systems has not been investigated.Objective: Big Data Analytics Systems (BDAS) have been proposed using rigorous SDLCs such as CRISP-DM, Team Data Science Process, and Domino Data Science Lifecycle, but their utilization for small business – or small teams called Very Small Entities (VSEs) – is scarcely reported given the requirements demanding human, technological and financial resources not available in small business. Given this problematic situation, new agile SDLCs for BDAS have been proposed such as Data-Driven Scrum, but some small organizations still require the utilization of a more systematic development process, and thus SDLCs based on ISO/IEC standards are expected.Methods: In this research, the design of Light Data Science – Analytics Methodology (LDSAM) and its pilot usability evaluation from a sample of 27 international practitioners are reported. LDSAM is a lightweight development methodology aligned to the ISO/IEC 29110 – Basic Profile – created especially for VSEs.Results: LDSAM was elaborated using Design Science Research Methodology. Initial usability evaluation results of LDSAM are satisfactory, but further empirical research is encouraged to advance to more mature and stable lightweight SDLCs for BDAS.Conclusion: The LDSAM was successfully developed, and its usability was evaluated by a pilot sample of international academics and professionals. Favorable results were obtained on the usability metrics for the proposed LDSAM SDLC for BDAS. |
Bibliometric Panorama of Accounting Information System Research EvolutionHanna Mysaka, Ivan DerunActa Informatica Pragensia 2024, 13(1), 134-164 | DOI: 10.18267/j.aip.2326928 Accounting information systems (AIS) are closely connected with using automated accounting data processing technologies, which increase reliability and prompt information delivery to stakeholders for management decision-making. The purpose of the article is to provide the AIS research domain with an additional impetus for further development based on a comprehensive characterization of quantitative parameters and systematic rethinking of trends in the evolution of the scientific themes. The article contains the methods of bibliometric analysis and chronological literature review based on clustering of keywords from a sample of AIS research indexed in Scopus in 1973–2023. The key findings indicate the nicheness of the AIS research problems, due to which the evaluation of the scientific output requires a multifaceted approach. It is found out which countries, journals, articles and authors play a decisive role in the formation of trends in the AIS research domain. Author keywords are used to assess the content orientation of the AIS research themes and to identify patterns of its evolution. We conclude that there is a content exhaustion in AIS scientific problems and the need to find new objects of research that correspond to the trends of Industry 4.0. |
Exploring Design Principles for SME Complementor-Suitable Digital PlatformsLukas Rudolf Germut Fitz, Jochen ScheegActa Informatica Pragensia 2026, 15(2), 382-399 | DOI: 10.18267/j.aip.3071302 Background: Some of the world’s most valuable platform businesses rely on products and services provided by small and medium-sized enterprises (SMEs). Though, the modern digital platform economy is increasingly shaped by uncertainties and power asymmetries benefitting dominant platform owners and threatening smaller players participating as complementors in those ecosystems. Negative consequences include lock-in effects and platform dependency, exploitative participation terms and eroded entrepreneurial autonomy on the SMEs’ side, which altogether harm the digital platforms’ long-term viability, too. Addressing these issues, this paper investigates design principles for digital platforms taking SME complementors’ needs into account.Objective: This study investigates design principles for digital platforms that enhance suitability for SMEs as complementors, focusing on stakeholder-centric platform design approaches that better accommodate SME-specific needs and requirements. In this, this study aims to address current negative developments concerning imbalanced power dynamics and uncertainties emerging from platform owner-SME-partnerships in dominant digital platform ecosystems.Methods: A qualitative reflective meta-analysis approach was employed, combining explorative expert interviews with SME specialists and a thematic literature review of SME platform design research. The methodology synthesized findings to identify meta-requirements and derive design principles through interpretive analysis.Results: Eleven meta-requirements were identified and synthesized into four design principles: the principle of SME empowerment, the principle of open boundaries, the principle of transparent and fair participation terms, and the principle of reflection of individuality. In combination, these principles aim to inform future digital platform design that takes SME complementor needs into account.Conclusion: The conceptual proposal of four design principles guides researchers and practitioners in creating SME-suitable digital platforms with stakeholder-centric design approaches. The principles enable digital platform models that accommodate diverse SME requirements, enhance participation experiences, and foster collaborative ecosystems tailored to SME characteristics and their operational contexts. |
Fairness-Aware Multimodal Machine Learning for Retail Stock Prediction from Sentiment and Market DataSanjay Rastogi, Kamal Upreti, Uma Shankar, Pravin Ramdas Kshirsagar, Tan Kuan Tak, Rituraj Jain, Ganesh Veluswwamy RadhakrishnanActa Informatica Pragensia 2026, 15(2), 307-326 | DOI: 10.18267/j.aip.2991818 Background: The introduction of retail investors to AI-powered trading platforms and especially on emerging markets, has resulted in a new set of risks linked to algorithmic bias and financial forecasting fairness. Social media sentiment and structured data multimodal strategies have demonstrated a potential, but frequently do not have ethical considerations.Objective: This work proposes a multimodal model predictive control (MPC) framework grounded in fairness-based forecasting of next-day returns on stock in stock market settings, particularly ethical behaviour and transparency of the model on retail markets.Methods: We combine BERT-based sentiment analysis of Reddit discussions and organized stock market indicators and use XGBoost as the fundamental model. Bias is measured using fairness metrics, including demographic parity difference and equal opportunity difference. Debiasing measures such as reweighting and stratified calibration were used to curb the differences in stock categories.Results: The first model has an overall accuracy of 72.3 with the highest accuracy of 83.1 in the case of Tesla – representing bias in the model. Fairness assessment shows some significant differences (DPD=0.23, EOD=0.31), but the mitigation decreases to 0.07. However, the massive performance improvement after adjustment brings up the issue of overfitting or fairness overcorrection.Conclusion: While the proposed debiased framework successfully reduces algorithmic bias, the trade-off between fairness and generalizability underscores the need for caution. These results hold significant implications for digital trading systems and regulatory frameworks of emerging economies such as India, where explainability and fairness of AI models are significant for ethical financial engagement. |

Data Quality in Estimates from Probability-Based Online Panels: Systematic Review and Meta-AnalysisAndrea Ivanovska, Michael Bosnjak, Vasja VehovarActa Informatica Pragensia 2026, 15(1), 173-197 | DOI: 10.18267/j.aip.2792991 Background: General population surveys now increasingly use nonprobability samples from access panels instead of probability-based methods, which often leads to lower-quality estimates. In response, many official and academic surveys have adopted probability-based online panels (PBOPs), which use probability sampling and retain participants for follow-up surveys. While these panels reduce costs compared to one-time surveys, they still face low response rates and other challenges that may affect data quality.Objective: This study aimed to assess the accuracy of PBOPs by synthesising evidence on relative bias (RB), and to examine how RB varies by country, domain, measurement level, and item sensitivity.Methods: A systematic review yielded 44 eligible studies from 12 countries, and 1,897 effect sizes of absolute RB from studies that compared PBOP estimates to benchmarks. A three-level random effects meta-analytic model accounted for variance across studies, within studies and sampling variance. Moderator analyses evaluated the influence of country, item topic, measurement level and sensitivity on RB. Sensitivity analyses excluded the top 5% of RB outliers to test robustness.Results: The pooled RB was 23.14% (95% CI: 18.38%–27.91%) and heterogeneous. Most variance was attributed to within-study item-level differences. Country and topic did not significantly moderate RB. Items with high topic sensitivity had significantly higher RB (+19.33%) than items with no sensitivity. Ordinal items had significantly lower RB than nominal (–14.90%). However, when sensitivity and measurement level were modelled together, substantial residual heterogeneity remained.Conclusion: While PBOPs offer cost and logistical advantages, they require careful design considerations to lower substantial bias, especially regarding item sensitivity and measurement scale. PBOPs may not be suitable for certain question types, like sensitive or low-prevalence behaviours, especially when high accuracy is needed. Improved methodological planning and innovations are needed to improve PBOP data quality. |
Blockchain in Bioinformatics Data Security: Systematic Evidence, Research Gaps and Pathways ForwardDennis Opoku Boadu, Fredrick Boafo, Kwabena Owusu-Mensah, Michael Kwakye, Isaac OseiActa Informatica Pragensia 2026, 15(2), 566-592 | DOI: 10.18267/j.aip.312564 Background: The growth of high-throughput sequencing and multi-omics research has intensified the need for secure, interoperable and transparent data management infrastructures. Blockchain technology has been widely proposed as a potential solution; however, its feasibility, empirical maturity and comparative performance in bioinformatics remain unclear.Objective: This systematic review analyses blockchain applications in bioinformatics, highlighting claimed security and governance benefits, comparing them with traditional data security approaches, discussing implementation challenges and assessing the empirical rigor of existing studies using a structured quality assessment framework.Methods: This overview was conducted using Scopus, ScienceDirect, IEEE Xplore, ACM Digital Library and SpringerLink for publications from 2014 to 2024. Search strings combined blockchain, bioinformatics and security-related terms. Sixty-five studies met the inclusion criteria. Each study was evaluated using five equally weighted quality dimensions: application specificity, clarity of benefits, empirical evaluation, challenge articulation and reproducibility.Results: Most studies focused on blockchain use cases in genomic data sharing, provenance tracking and access control, with a strong emphasis on conceptual benefits such as immutability and auditability. Fewer studies provided empirical evaluations or direct comparisons with traditional security mechanisms. Quality assessment results revealed a predominance of conceptual and prototype-level contributions; over half of the studies lacked empirical benchmarking and reproducibility was frequently limited. Heterogeneity in blockchain architectures and the absence of standardized genomic benchmarking environments hindered cross-study comparison. No study demonstrated deployment within a production-scale genomic pipeline.Conclusion: Blockchain demonstrates conceptual potential for enhancing provenance, decentralized governance and tamper-resistant auditing in bioinformatics data management. However, empirical validation remains limited and significant technical, regulatory and organizational challenges persist. The current evidence base is insufficient to support large-scale adoption. Future research should prioritize benchmarking using realistic genomic workloads, hybrid architectures that integrate off-chain storage, consent-aware governance models and alignment with regulatory frameworks such as GDPR and HIPAA. |
Acceptability of Telemedicine Among Nurses Caring for Older Adults: A Quantitative Descriptive StudySimona Hvaliè-Touzery, Nejc Berzelak, Mojca ©etinc, Vesna Dolnièar, Angela Kydd, Jerneja Laznik[Ahead of Print]Acta Informatica Pragensia X:X | DOI: 10.18267/j.aip.319122 Background: Telemedicine, though decades old, saw only limited use until the COVID-19 pandemic, but despite increasing adoption, barriers to using telemedicine remain pervasive.Objective: We sought to explore the acceptability of telemedicine among nurses caring for older adults by extending the Technology Acceptance Model (TAM).Methods: A descriptive, non-experimental, quantitative research design was used. An online survey was administered to Slovenian registered nurses experienced in caring for older adults (n = 244), of whom 111 with no prior telemedicine experience were included in the analysis. Data were collected between September and December 2023 and analysed using descriptive statistics, Pearson correlations and ordered logistic regression models.Results: Willingness to use telemedicine was positively associated with perceived usefulness for nursing practice and patient empowerment (both p < .05) and negatively influenced by technology anxiety and technology-based ageism (both p < .05). Technology anxiety was particularly associated with stronger resistance among the nurses least willing to use telemedicine. Higher self-rated telemedicine knowledge correlated positively with willingness to use telemedicine (p < .05), but this relationship ceased to be significant after perceived usefulness and technology anxiety were included in the model. Age was also negatively associated with nurses’ willingness to use telemedicine (p < .05), suggesting generational barriers.Conclusion: Extending the TAM with domain-specific measures related to nursing practice and patient empowerment and with affective components – technology anxiety and technology-based ageism – improved its power to explain willingness to use telemedicine among nurses. Telemedicine knowledge is an important external factor, so professional development should help to improve digital skills and address ageist assumptions to support a socially inclusive and confident nursing workforce. |
Development and Validation of a Blockchain Literacy ScaleKemal Elciyar, Neºe SatılmıºActa Informatica Pragensia 2025, 14(1), 26-41 | DOI: 10.18267/j.aip.2518924 Background: The use of blockchain is increasing daily and has become a transformative technology across various sectors. The competent use of blockchain is becoming a fundamental skill. Although numerous studies have attempted to measure digital competencies, the absence of research specifically focused on blockchain literacy has left a significant gap. Objective: The aim of this study is to provide a systematic review of digital literacy and blockchain measurement frameworks, comparing them with existing theoretical digital competence models. Methods: Furthermore, we introduce a newly developed Blockchain Literacy Scale (BLS). The factorial structure of the BLS is assessed to explore its multidimensional nature. A sample of 591 Turkish college students completed a questionnaire to empirically test its reliability, validity and general applicability. Results: Both Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) supported a five-factor structure for the BLS, comprising: information access, information evaluation, economic literacy, legal literacy and risk literacy. The scale demonstrated strong internal consistency and reliability. Conclusion: Directions for future research and the practical implications of the newly developed BLS are discussed in the conclusion. |
Antecedents of Test Automation Adoption in DevOps Continuous Testing: A Systematic Literature Review Through the TOE FrameworkAnuji Isara Vithana, Kelum Asanga Akurugoda Gamage, Dilani Wickramaarachchi, Ruwan Wickramarachchi, Shan JayasingheActa Informatica Pragensia 2026, 15(1), 253-273 | DOI: 10.18267/j.aip.2972745 Background: The rapid evolution of software engineering has positioned DevOps practices and Continuous Testing (CT) as critical approaches for achieving speed, quality, and reliability in software delivery. Test automation is central to CT, yet its adoption remains inconsistent due to a complex interplay of technological, organizational, and environmental conditions.Objective: This study employs a systematic literature review guided by the Technology–Organization–Environment (TOE) framework to identify, categorize, and synthesize the antecedents that influence the test automation adoption in DevOps continuous testing.Methods: Using the PRISMA protocol, 49 peer-reviewed studies published between 2015 and 2025 were systematically analyzed, yielding 61 distinct factors comprising 29 technological, 19 organizational, and 13 environmental antecedents. These factors were further consolidated into thematic clusters to enhance analytical clarity and reduce fragmentation.Results: The findings demonstrate that technological and organizational drivers, including relative advantage, compatibility, top management support, and employee competence, dominate the literature, while environmental influences such as competitive pressure, regulatory requirements, and vendor ecosystems are comparatively underexplored. This imbalance indicates that although the TOE framework is widely applied in technology adoption studies, empirical research has given greater attention to internal adoption enablers than to external pressures. By simplifying and synthesizing the factors into coherent sub-themes, this study contributes to both theory and practice by offering a structured lens through which test automation adoption can be examined in the DevOps CT context. Theoretically, it validates the relevance of TOE for analysing multidimensional adoption dynamics, while practically, it provides managers with evidence-based insights to prioritize critical factors when planning automation initiatives. Methodologically, it demonstrates the importance of transparent and replicable review processes for advancing cumulative knowledge.Conclusion: Overall, the study bridges fragmented findings into a coherent framework and strengthens understanding of adoption strategies in continuous testing environments. |
Personalized Learning Analytics Through Static Code Analysis in Computer Science EducationMarek Horváth, Emília Pietriková, Filip GurbáµActa Informatica Pragensia 2026, 15(1), 54-71 | DOI: 10.18267/j.aip.2833171 Background: Learning programming is often difficult for beginners, primarily because of the challenge of providing timely and personalized feedback in large educational environments. While automated assessment systems have improved efficiency in grading and feedback, they typically focus on correctness and often lack personalized guidance concerning code quality, readability, and maintainability.Objective: This study aims to investigate whether integrating static code analysis into automated assessment systems to provide personalized feedback can effectively enhance students code quality, learning process, and engagement in programming courses.Methods: We designed a personalized feedback system integrated with static analysis tools (Cppcheck and Clang-format), deployed within an existing automated assessment platform used by undergraduate programming students. The system was evaluated in a controlled experiment involving 60 students randomly divided into control and treatment groups. The effectiveness of personalized feedback was measured through quantitative metrics (style violations, potential bugs, and design issues), qualitative surveys, and submission behaviours over multiple assignments.Results: Results demonstrated that students receiving personalized feedback improved their code quality, reducing the number of style violations by 76%, potential bugs by 52%, and structural issues by 32% compared to the control group. Students also expressed higher satisfaction, increased motivation, and greater willingness to iteratively refine their code based on personalized feedback.Conclusion: The integration of static code analysis for personalized feedback not only enhances code quality but also helps a deeper understanding of good programming practices among students. Future research should focus on making feedback systems more adaptive, incorporating intelligent tutoring techniques, and exploring long-term impacts on programming habits and skill retention. |

However, only the ascent of tools such as ChatGPT brought AI into a broader public consciousness, as people started using it for a broad spectrum of tasks and questions.Objective: The goal of this overview article is to present a new perspective on AI issues in the context of the social sciences and, more specifically, political science. Indeed, AI tools play an important role in the political process—a fact reflected by governments and other political actors, including political parties.Methods: The qualitatively and interpretively oriented paper seeks to demonstrate existing connotations of the relationship between AI and politics in the Czech context. The text is designed as an overview based on secondary sources. We first focus on AI popularity and use in the general public and public institutions. Then the article focuses on government strategies with implications for international organizations. The final part outlines the relationship between generative AI and Czech political parties.Results: The results indicate that the popularity of AI grew substantially after OpenAI launched its model. Nowadays, generative AI-based tools are commonly used by various public institutions. To date, the Government of the Czech Republic has issued two national strategies on AI issues. Political parties are among the actors using generative AI on a daily basis.Conclusion: The analysis seeks to fill in the blanks in this under-researched area and to demonstrate what kind of interdisciplinary implications of the AI–politics relationship can be examined. Moreover, we view the gradual adoption of AI tools as the next step in the process of adaptation to new digital tools that started years ago. |
Automated Machine Learning in Action: Performance Evaluation for Predictive Analytics TasksNicolas LeyhActa Informatica Pragensia 2026, 15(1), 72-89 | DOI: 10.18267/j.aip.2883062 Background: As organizations increasingly seek data-driven insights, the demand for machine learning (ML) expertise outpaces the current workforce supply. Automated Machine Learning (AutoML) frameworks help close this gap by streamlining the ML pipeline, making advanced modeling accessible to non-specialists.Objective: This study evaluates the performance of four open-source AutoML frameworks—Auto-Keras, Auto-Sklearn, H2O, and TPOT—in predictive analytics, focusing on both binary and multiclass classification. The goal is to identify performance strengths and limitations under varying dataset conditions and propose improvements for framework optimization.Methods: Quantitative experimental research design was employed. 22 publicly available datasets were selected from established benchmarking sources, covering diverse predictive analytics challenges. Framework performance was assessed across twelve data segments, defined by characteristics such as sample size, feature count, and categorical feature proportion. Evaluation metrics included AUC for binary and accuracy/F1 for multiclass classification tasks, with standardized runtime constraints applied to ensure comparability.Results: The findings show that H2O delivered strong results across diverse datasets, particularly for binary classification. However, no single framework achieved superior performance across all data segments. Auto-Sklearn performed well in multiclass classification, especially with higher feature counts, while Auto-Keras and TPOT demonstrated variable outcomes depending on dataset complexity. Performance declined notably in scenarios with high categorical proportions, severe class imbalance, or extensive missing values.Conclusion: This study demonstrates that AutoML frameworks can substantially support predictive analytics but exhibit distinct strengths and limitations under specific data conditions. While H2O proved most robust overall, targeted refinements such as enhancing feature selection in Auto-Keras and improving categorical variable handling in Auto-Sklearn could further optimize performance. The findings provide actionable insights for both practitioners selecting frameworks and developers enhancing AutoML design, highlighting the need for ongoing innovation to ensure adaptability to complex predictive analytics tasks. |
