Item type:Publication, Benchmarking Sentence Encoders in Associating Indicators With Sustainable Development Goals and Targets(Institute of Electrical and Electronics Engineers (IEEE), 2025) ;Gjorgjevikj, Ana; ; The United Nations’ 2030 Agenda for Sustainable Development balances the economic, environmental, and social dimension of sustainable development in 17 Sustainable Development Goals (SDGs), monitored through a well-defined set of targets and global indicators. Although essential for humanity’s future well-being, this monitoring is still challenging due to the variable quality of the statistical data of global indicators compiled at the national level and the diversity of indicators used to monitor sustainable development at the subnational level. Associating indicators other than the global ones with the SDGs/targets may help not only to expand the statistical data, but to better align the efforts toward sustainable development taken at (sub)national level. This article presents a model-agnostic framework for associating such indicators with the SDGs and targets by comparing their textual descriptions in a common representation space. While removing the dependence on the quantity and quality of the statistical data of the indicators, it provides human experts with data-driven suggestions on the complex and not always obvious associations between the indicators and the SDGs/targets. A comprehensive domain-specific benchmarking of a diverse sentence encoder portfolio was performed first, followed by fine-tuning of the best ones on a newly created dataset. Five sets of indicators used at the (sub)national level of governance (around 800 indicators in total) were used for the evaluation. Finally, the influence of 40 factors on the results was analyzed using explainable artificial intelligence (xAI) methods. The results show that 1) certain sentence encoders are better suited to solving the task than others (potentially due to their diverse pre-training datasets), 2) the fine-tuning not only improves the predictive performance over the baselines but also reduces the sensitivity to changes in indicator description length (performance drops even by up to 17% for baseline m... - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Evaluating Trustworthiness in AI: Risks, Metrics, and Applications Across Industries(MDPI AG, 2025-07-04) ;Nastoska, Aleksandra ;Jancheska, Bojana ;Rizinski, MaryanEnsuring the trustworthiness of artificial intelligence (AI) systems is critical as they become increasingly integrated into domains like healthcare, finance, and public administration. This paper explores frameworks and metrics for evaluating AI trustworthiness, focusing on key principles such as fairness, transparency, privacy, and security. This study is guided by two central questions: how can trust in AI systems be systematically measured across the AI lifecycle, and what are the trade-offs involved when optimizing for different trustworthiness dimensions? By examining frameworks such as the NIST AI Risk Management Framework (AI RMF), the AI Trust Framework and Maturity Model (AI-TMM), and ISO/IEC standards, this study bridges theoretical insights with practical applications. We identify major risks across the AI lifecycle stages and outline various metrics to address challenges in system reliability, bias mitigation, and model explainability. This study includes a comparative analysis of existing standards and their application across industries to illustrate their effectiveness. Real-world case studies, including applications in healthcare, financial services, and autonomous systems, demonstrate approaches to applying trust metrics. The findings reveal that achieving trustworthiness involves navigating trade-offs between competing metrics, such as fairness versus efficiency or privacy versus transparency, and emphasizes the importance of interdisciplinary collaboration for robust AI governance. Emerging trends suggest the need for adaptive frameworks for AI trustworthiness that evolve alongside advancements in AI technologies. This paper contributes to the field by proposing a comprehensive review of existing frameworks with guidelines for building resilient, ethical, and transparent AI systems, ensuring their alignment with regulatory requirements and societal expectations. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Multiword Discourse Markers Across Languages: A Linguistic and Computational Perspective(Wiley, 2025-04-22) ;Apostol, Elena‐Simona ;Truică, Ciprian‐Octavian ;Damova, Mariana ;Silvano, PurificaçãoOleškeviciene, Giedre ValunaiteDiscourse markers (DMs) are linguistic expressions that convey different semantic and pragmatic values, managing and organizing the structure of spoken and written discourses. They can be either single-word or multiword expressions (MWE), made up of conjunctions, adverbs, and prepositional phrases. Although DMs are the focus of many studies, some questions regarding the interoperability of taxonomies and automatic identification and classification require further research. We aim to tackle these issues by offering a critical analysis and discussing the constitution of a multilingual corpus in 10 languages, i.e., English, Lithuanian, Bulgarian, German, Macedonian, Romanian, Hebrew, Polish, European Portuguese, and Italian. The novel two-level annotation approach is based on (i) signaling the existence or non-existence of DMs in a given text, and (ii) applying the ISO-24617 standard to annotate the DMs’ discourse relation and communicative function in the corpora. Additionally, we introduce prediction models for detecting the presence of DMs within a text. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Pressure Related Ocular Parameters in Caucasian Patients with Primary Open-Angle Glaucoma(Savvy Science Publisher, 2021-06-02) ;Galina, Dimitrova ;Antonela, Ljubic; ;Keti, TagasovskaUrosh, TomasevicObjectives: To investigate pressure related ocular parameters (intraocular pressure (IOP), estimated trans-lamina cribrosa pressure difference (TLPD) and ocular perfusion pressure (OPP) in Caucasian patients with primary open angle glaucoma (POAG) and control subjects. Methods: This is an observational cross-section study that included 57 subjects (27 patients with open-angle glaucoma and 30 healthy control subjects). All subjects underwent ophthalmic and systemic measurements in order to evaluate pressure related ocular parameters – IOP (mmHg), OPP (mmHg), and TLPD (mmHg) based on established formulas. The differences in the IOP, OPP and TLPD values between patients with POAG and control subjects were evaluated. Results: Intraocular pressure and TLPD were significantly higher in patients with glaucoma (mean IOP= 18.93 ± 4.53 mmHg; TLPD= 9.47 ± 5.02 mmHg), than in control subjects (IOP= 16.47 ± 2.60 mmHg; TLPD= 6.82 ± 3.60 mmHg) (p=0.017 and p=0.025 respectively). In univariate logistic progression, IOP and TLPD were significant predictors for POAG. Conclusion: Our results suggest that in addition to IOP, TLPD is also significantly higher in Caucasian patients with POAG than in control subjects and both parameters are significant predictors of POAG. This suggests that TLPD may have a role in the pathogenesis of POAG. - Some of the metrics are blocked by yourconsent settings

Our work is a general toolbox which will enable educators to tailor their classes to different areas within the field of informatics. We thus aim to answer the following questions: “How to prepare well for an informatics class?”, “How to conduct an informatics class successfully?” and “How to evaluate a properly conducted informatics lesson?”. Our paper will familiarize educators with the whole cycle of designing a successful informatics course. We will specifically target the microlevels of a course, a lesson. We will discuss different aspects of every lesson: suitable methods for organization and planning of a lesson, structural elements of a lesson, types of lessons, didactic goals, appropriate selection of teaching material, active methods for teaching and learning, manners for fostering interaction between students and teachers and among students themselves, approaches to fully engage students, lesson delivery models, individualized techniques to target the learning goals of each student, assessment and evaluation of students. We will also take into consideration teachers’ preparedness including their expertise of the material, and their didactical, technical and psychological readiness. The quality of an informatics course lies in the relationship between educators and their students. It is a complex dynamic between teachers’ goals, plans, means, methods and organization, and students’ expectations, abilities, and motivation. Our paper reaches an equilibrium point between all the building blocks of the teaching process of the educator and learning experience of the students. Our focus is put on the teacher and their teaching methods and tactics. We perceive the teachers as pilots leading a full airplane, a class of students. They have a palette of gadgets available, and they need to make a specific choice for the plane to conformably fly and to finally land on the exact coordinates of the intended location. In our case, the fancy gadgets are all traditional and modern learning tools available to the teacher and the intended location is the goal of the teacher for the class. How can educators use the tools to meet their didactic goals? When should they use them at what times? What specific tools should they select for special educational tasks? What does this choice depend on? Our paper will take a holistic view of all components of the process of teaching and learning informatics. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Identification of HIV Inhibitors Using Graph Neural Networks(IEEE, 2024-05-20) ;Georgiev, Dimitar; Graph neural networks (GNN), primed to extract knowledge and discover patterns in graph-structured data, have received particularly increased attention in biomedical research. By integrating information from a variety of biomedical knowledge repositories they offer a fast and efficient computational alternative approach to the costly and time-consuming process of drug development and research. The core contributions of this paper include the design and empirical evaluation of several GNN-based models for the identification of potential HIV (Human Immunodeficiency Virus) inhibitors. In particular, the predictive power of model variants based on Graph Attention Network (GAT), Graph Isomorphism Network (GIN), and Continuous Kernel-Based Graph Convolutional Network, specifically developed to handle molecular data, have been investigated. To assess the effectiveness of the proposed models, the Stanford open graph benchmark dataset for molecular data ogbg-molhiv was used. Furthermore, two types of molecular fingerprints have been proposed to augment the molecular representation in the proposed graph neural models, leading to better performance standing compared to the original models. The paper provides a detailed description of the proposed models for identifying HIV inhibitors, followed by a comparative analysis of the experimental results focusing on a discussion of the challenges we face and future research directions that could be investigated.
