[{"publication":"Data & Knowledge Engineering","abstract":[{"lang":"eng","text":"Large Language Models (LLMs) have demonstrated remarkable performance across a wide range of natural language processing tasks. However, their effectiveness in low-resource languages remains underexplored, particularly in complex tasks such as end-to-end Entity Linking (EL), which requires both mention detection and disambiguation against a knowledge base (KB). In earlier work, we introduced IndEL — the first end-to-end EL benchmark dataset for the Indonesian language — covering both a general domain (news) and a specific domain (religious text from the Indonesian translation of the Quran), and evaluated four traditional end-to-end EL systems on this dataset. In this study, we propose ELEVATE-ID, a comprehensive evaluation framework for assessing LLM performance on end-to-end EL in Indonesian. The framework evaluates LLMs under both zero-shot and fine-tuned conditions, using multilingual and Indonesian monolingual models, with Wikidata as the target KB. Our experiments include performance benchmarking, generalization analysis across domains, and systematic error analysis. Results show that GPT-4 and GPT-3.5 achieve the highest accuracy in zero-shot and fine-tuned settings, respectively. However, even fine-tuned GPT-3.5 underperforms compared to DBpedia Spotlight — the weakest of the traditional model baselines — in the general domain. Interestingly, GPT-3.5 outperforms Babelfy in the specific domain. Generalization analysis indicates that fine-tuned GPT-3.5 adapts more effectively to cross-domain and mixed-domain scenarios. Error analysis uncovers persistent challenges that hinder LLM performance: difficulties with non-complete mentions, acronym disambiguation, and full-name recognition in formal contexts. These issues point to limitations in mention boundary detection and contextual grounding. Indonesian-pretrained LLMs, Komodo and Merak, reveal core weaknesses: template leakage and entity hallucination, respectively—underscoring architectural and training limitations in low-resource end-to-end EL.11Code and dataset are available at https://github.com/dice-group/ELEVATE-ID."}],"language":[{"iso":"eng"}],"keyword":["LLMs","Evaluation","End-to-end EL","Indonesian"],"year":"2026","date_created":"2025-08-24T11:38:51Z","title":"ELEVATE-ID: Extending Large Language Models for End-to-End Entity Linking Evaluation in Indonesian","type":"journal_article","status":"public","department":[{"_id":"574"}],"user_id":"71039","_id":"60990","article_type":"original","publication_identifier":{"issn":["0169-023X"]},"page":"102504","intvolume":"       161","citation":{"apa":"Gusmita, R.

However, the challenge is to develop active polymers that exhibit an antimicrobial effect and are compatible with human cells. Different studies aiming for biocidal polymers active in soluble mode, focused on the ratio of cationic to hydrophobic groups, while only marginal knowledge is available for immobilized components. Here a strong hydrophilic electrolyte 4‐vinylbenzyltrimethylammonium chloride (TMA) is chosen as the cationic component. The block composition of the polycationic segment is modified with styrene (Sty) regarding the amphiphilic balance. To adsorb such polymers onto titanium surfaces they are equipped with a polyphosphonic acid anchor block by sequential reversible‐addition‐fragmentation chain‐transfer polymerization (RAFT) polymerization. The polymer composition affected the wetting behavior of adsorbed coatings with water contact angles ranging from 17° to 72°, while zetapotential measurements confirmed high extent of positive charges for all adsorbed polymer coatings. The fundamentally modified block composition resulted in significantly improved cytocompatibility. Antimicrobial efficacy in early bacterial adhesion is still retained from slightly antiadhesive coatings to combined antiadhesive/biocidal activity depending on Sty/TMA ratio in random polymers while a block copolymer revealed lowest antimicrobial effect.</jats:p>","lang":"eng"}],"status":"public","publisher":"Wiley","date_updated":"2025-04-11T07:43:06Z","date_created":"2025-04-11T07:35:39Z","author":[{"first_name":"Cornelia","last_name":"Wolf‐Brandstetter","full_name":"Wolf‐Brandstetter, Cornelia"},{"first_name":"Rafael","full_name":"Methling, Rafael","last_name":"Methling"},{"first_name":"Dirk","full_name":"Kuckling, Dirk","id":"287","last_name":"Kuckling"}],"title":"Adsorbable and Antimicrobial Amphiphilic Block Copolymers with Enhanced Biocompatibility","doi":"10.1002/mame.202500078","main_file_link":[{"url":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.202500078"}],"publication_identifier":{"issn":["1438-7492","1439-2054"]},"publication_status":"published","year":"2025","citation":{"bibtex":"@article{Wolf‐Brandstetter_Methling_Kuckling_2025, title={Adsorbable and Antimicrobial Amphiphilic Block Copolymers with Enhanced Biocompatibility}, DOI={<a href=\"https://doi.org/10.1002/mame.202500078\">10.1002/mame.202500078</a>}, journal={Macromolecular Materials and Engineering}, publisher={Wiley}, author={Wolf‐Brandstetter, Cornelia and Methling, Rafael and Kuckling, Dirk}, year={2025} }","mla":"Wolf‐Brandstetter, Cornelia, et al. “Adsorbable and Antimicrobial Amphiphilic Block Copolymers with Enhanced Biocompatibility.” <i>Macromolecular Materials and Engineering</i>, Wiley, 2025, doi:<a href=\"https://doi.org/10.1002/mame.202500078\">10.1002/mame.202500078</a>.","short":"C.

Thus, in 2019, the so-called SpraySyn1 burner was introduced (SS1), which was subsequently characterized in numerical and experimental studies. Based on this research, a modification of the nozzle design was proposed, which has now been considered in the successor model, SpraySyn2 (SS2). As little is known about the effect of the nozzle adaptation on the particle formation, we operated both burners under identical operating conditions to produce maghemite. The final powder comparison showed that SS2 yielded considerable higher specific surface areas (associated with smaller primary particle sizes), lower polydispersity, and higher phase purity. To obtain further information on the size distributions of aggregates and agglomerates generated by SS2, aerosol samples were extracted by hole in a tube (HIAT) sampling and characterized by scanning mobility particle sizing (SMPS). Samples were extracted along the centerline at different heights above the burner (HAB) above the visible flame tip (>7 cm), and quenching experiments were performed to extract the aerosol samples at different dilution rates. Thereby, it was demonstrated that performing detailed quenching experiments is crucial for obtaining representative HIAT-SMPS data. In particular, agglomerates/aggregate sizes were overestimated by up to ~70 % if samples were not sufficiently diluted. If sufficient dilution was applied, distribution widths and mean particle mobility diameters were determined with high accuracy (sample standard derivation <5 %). Our data suggested the evolution of primary particle sizes was mostly completed <7 cm HAB and it was shown aggregates/agglomerates present above the visible flame were compact in structure (non- fractal). The mean diameter of the particle ensemble grew along the centerline from 6.9 nm (7 cm) to 11.4 nm (15 cm), while distribution widths grew from 1.42 to 1.52.","lang":"eng"}],"publication":"Applications in Energy and Combustion Science","title":"Maghemite nanoparticles synthesis via spray flame synthesis and particle characterization by hole in a tube sampling and scanning mobility particle sizing (HIAT-SMPS)","date_created":"2024-02-05T12:02:57Z","publisher":"Elsevier","year":"2024"},{"type":"journal_article","status":"public","user_id":"103813","_id":"53200","article_type":"original","article_number":"114582","publication_identifier":{"issn":["0148-2963"]},"publication_status":"published","intvolume":"       177","citation":{"apa":"Ozuna, E., &#38; Steinhoff, L.

For example, property damage to shared accommodations imposes burdens on both sharing platforms and hosts, especially if misbehaving guests purposefully, not coincidentally conceal, or fail to report damages. Such misbehavior might be facilitated by remote listing management and the lack of face-to-face interactions between hosts and guests. Therefore, this study investigated the effects of host–guest interaction modes (face-to-face, online-only) and frequency on guests’ misbehavior concealment intentions. Social identification and irritation emerged as bright- and dark side mediators, respectively. Guests who interacted face-to-face (vs. online-only) with hosts exhibited weaker intentions to conceal their misbehavior due to increased social identification. Platforms can elicit social identification by engaging guests in virtual communities. However, when face-to-face interactions become excessive, guests experience irritation and are more likely to conceal their misbehavior. These insights offer practical implications for both peer-to-peer sharing platforms and hosts.","lang":"eng"}],"language":[{"iso":"eng"}],"keyword":["Sharing economy","Customer misbehavior","Peer-to-peer services","Face-to-face interactions","Experimental research"],"year":"2024","date_created":"2024-04-04T08:16:27Z","publisher":"Elsevier BV","title":"“Look me in the eye, customer”: How do face-to-face interactions in peer-to-peer sharing economy services affect customers’ misbehavior concealment intentions?"},{"main_file_link":[{"url":"https://www.researchgate.net/profile/Simon-Hemmrich-3/publication/374550987_The_Value_of_Reputation_Systems_in_Business_Contexts_-A_Qualitative_Study_Taking_the_View_of_Buyers/links/652406723ab6cb4ec6d01951/The-Value-of-Reputation-Systems-in-Business-Contexts-A-Qualitative-Study-Taking-the-View-of-Buyers.pdf"}],"conference":{"start_date":"2024-01-03","name":"Hawaii International Conference on System Sciences 2024","location":"Honolulu","end_date":"2024-01-06"},"title":"The Value of Reputation Systems in Business Contexts–A Qualitative Study Taking the View of Buyers","author":[{"first_name":"Simon","id":"83557","full_name":"Hemmrich, Simon","last_name":"Hemmrich"},{"first_name":"Jannika Marie","id":"74374","full_name":"Schäfer, Jannika Marie","last_name":"Schäfer"},{"first_name":"Philipp","id":"55603","full_name":"Hansmeier, Philipp","last_name":"Hansmeier"},{"id":"59677","full_name":"Beverungen, Daniel","last_name":"Beverungen","first_name":"Daniel"}],"date_created":"2024-06-27T09:52:26Z","date_updated":"2024-06-27T10:01:29Z","citation":{"ieee":"S.

However, these systems are relevant for prospective buyers to find a trustworthy seller. This observation applies especially to short-lived business relationships where fulfilling the performance promise is subject to a high degree of uncertainty. This paper explores the value of a reputation system for a business-to-business (B2B) context and focuses on three novel solutions for designing reputation systems. These solutions include selling ratings, conducting ratings as payments, and employing a counter-rating mechanism. We interview buyers to fathom the added value of these solutions in different contexts. Our findings suggest that such a system is useful for companies acting in less transparent markets and also helps when companies already have a good market overview. Depending on the market conditions and business context, the perceived value of the proposed system varies."}],"type":"conference","publication":"Proceedings of the 57th Hawaii International Conference on System Sciences"},{"publication":"Proceedings of the Fifth Conference of the International Network for Didactic Research in University Mathematics (INDRUM 2024, 10-14 June 2024)","abstract":[{"lang":"eng","text":"In our paper, we present a study in which we investigate which strategies pre-service teachers (PSTs) use to find and, if necessary, reject possible candidates for congruence theorems for quadrilaterals.

This is especially true for adolescent immigrants who have not yet been able to finish education or gain qualifications relevant to joining the labour market. That is why many receiving countries have developed and implemented special programmes that aim at supporting immigrants' integration by facilitating their employability. Unfortunately, not much is known about the process of implementing these programmes or about how education systems, schools, and teachers are dealing with the new situation and target group. In this contribution, the implementation, development, and challenges of German Vocational Integration Classes (VIC), as an example of comparable programmes in the EU, are investigated to address this research gap. The paper considers the following exploratory research questions: (a) What challenges have been experienced by teachers and social workers in the implementation of VIC as well as in the integration of immigrants into the labour market in recent years? (b) How can these challenges be met in the long run and how should VIC be developed to better achieve its aims? \r\n\r\nMethods: To answer these questions, a sequential qualitative study containing questionnaire and interview elements was conducted. First, teachers and social workers involved in VIC filled in a questionnaire about their experiences and experienced challenges in implementing VIC (N = 46). Then, supplementing interviews were conducted with participants from the first sample in order to generate further insights and to contextualise the findings from the first study part (N = 14). \r\n\r\nFindings: From the respondents' answers, it appears that the VIC programme is well implemented. The results show, however, that central challenges continue to exist. This concerns, for example, legal regulations or the development of adequate curricula, but also the scope and quality of language education. In addition, problems have also been identified with regard to students' culture-specific education and their individual attitudes. These prevailing problems seem to affect schooling and educational processes. In addition, respondents report feeling left alone to deal with problems and that their experiences from their daily work in VIC and with immigrants are not sufficiently taken into account in policy and school-related decisions. \r\n\r\nConclusions: Although VIC seems well implemented, key challenges remain in the view of the participants. It was found that teachers cannot solve many of the identified problems themselves, as they require action at the level of policy or school organisation. For staff, this can be accompanied by increased stress and demotivation. For the young immigrants, the existing challenges can have a long-term impact on school success and transition to vocational education and training. The study thus highlights the importance of targeted and holistic strategies to support immigrant integration through education.

Dabei beruhen Zustandsüberwachungssysteme auf den folgenden Bausteinen: Sensorik, Datenvorverarbeitung, Merkmalsextraktion und -auswahl, Diagnose bzw. Prognose sowie einer Entscheidungsfindung basierend auf den Ergebnissen. Jeder dieser Bausteine erfordert individuelle Einstellungen, um ein geeignetes Zustandsüberwachungssystem für die jeweilige Anwendung zu entwickeln. Eine offene Fragestellung im Bereich der Zustandsüberwachung ergibt sich aufgrund der Unsicherheit der Zukunft, die sich in den zukünftigen Betriebs- und Umgebungsbedingungen zeigt. Diese Unsicherheit gilt es in allen Bausteinen zu berücksichtigen.\r\nDieser Beitrag konzentriert sich auf den Baustein Merkmalsextraktion und -selektion, mit dem Ziel anhand geeigneter Merkmale eine Prognose der nutzbaren Restlebensdauer mit hoher Genauigkeit realisieren zu können. Daher werden geeignete Merkmale aus dem Zeitbereich und daraus abgeleitete Zustandsindikatoren für die Restlebensdauerprognose von technischen Systemen vorgestellt. Dabei sind Zustandsindikatoren Kenngrößen zur Beobachtung des Zustands der kritischen Systemkomponenten. Anhand dreier Anwendungsbeispiele wird ihre Eignung evaluiert. Dabei werden Daten aus Lebensdauerversuchen unter instationären Betriebs- und Umgebungsbedingungen ausgewertet. Die auftretenden Unsicherheiten der Zukunft werden somit berücksichtigt. Die Beispielsysteme beruhen auf Gummi-Metall-Elementen und Wälzlagern. Aus den generierten Ergebnissen lässt sich schließen, dass die Zustandsindikatoren aus der betrachteten Zeitreihen-Toolbox auch unter unbekannten Betriebs- und Umgebungsbedingungen robust sind.\r\n"},{"text":"Due to the advances in digitalization, condition monitoring systems have found numerous applications in the industry due to benefits such as improved reliability and lowered costs through condition-based or predictive maintenance. Condition monitoring systems typically involve elements, such as data acquisition via suitable sensors, data preprocessing, feature extraction and selection, diagnostics, prognostics and (maintenance) decisions based on diagnosis or prognosis. For the application-specific development of a suitable condition monitoring system, each of these elements requires individual settings. Due to the uncertainty of the future, an open question arises in the condition monitoring field, which is reflected in unknown future operating and environmental conditions. This uncertainty needs consideration in all elements of a condition monitoring system.\r\nThis article focuses on feature extraction and selection, building on the hypothesis that the remaining useful life of a technical system can be predicted with high accuracy utilizing suitable features. In this article, health indicators derived from time-domain features that permit the monitoring of the health of critical system components are presented for predicting the remaining useful life of technical systems. Three distinct application examples based on rubber-metal elements and rolling-element bearings are evaluated to validate the suitability of the presented methods. Experimental data from accelerated lifetime tests conducted under non-stationary operating and environmental conditions are considered to take possible future uncertainties into account. It can be concluded from the acquired results that health indicators derived from the presented time series toolbox are robust to varying operating and environmental conditions.\r\n","lang":"eng"}],"date_created":"2021-11-22T07:42:44Z","author":[{"full_name":"Aimiyekagbon, Osarenren Kennedy","id":"9557","last_name":"Aimiyekagbon","first_name":"Osarenren Kennedy"},{"first_name":"Amelie","id":"54290","full_name":"Bender, Amelie","last_name":"Bender"},{"first_name":"Walter","last_name":"Sextro","full_name":"Sextro, Walter","id":"21220"}],"publisher":"VDI Verlag GmbH","date_updated":"2022-01-06T06:57:43Z","conference":{"end_date":"2021-11-17","location":"Würzburg","name":"3.

Motivated by the broad applicability of GNNs, we propose the family of so-called RankGNNs, a combination of neural Learning to Rank (LtR) methods and GNNs. RankGNNs are trained with a set of pair-wise preferences between graphs, suggesting that one of them is preferred over the other. One practical application of this problem is drug screening, where an expert wants to find the most promising molecules in a large collection of drug candidates. We empirically demonstrate that our proposed pair-wise RankGNN approach either significantly outperforms or at least matches the ranking performance of the naive point-wise baseline approach, in which the LtR problem is solved via GNN-based graph regression."}],"publisher":"Springer","date_created":"2021-11-11T14:15:18Z","title":"Ranking Structured Objects with Graph Neural Networks","quality_controlled":"1","year":"2021"},{"title":"Transforming into a Platform Provider: Strategic Options for Industrial Smart Service Providers","date_created":"2020-08-12T12:12:36Z","publisher":"Emerald Insight","year":"2021","issue":"4","quality_controlled":"1","language":[{"iso":"eng"}],"ddc":["380"],"keyword":["Smart service","Platform","Interdisciplinary research","Manufacturing company","Smart service provider","Platform economics","Information systems","Multi-sided markets","Business-to-business (B2B) markets"],"abstract":[{"text":"Purpose\r\nThe purpose of this paper is to identify strategic options and challenges that arise when an industrial firm moves from providing smart service toward providing a platform.\r\n\r\nDesign/methodology/approach\r\nThis conceptual study takes on a multidisciplinary research perspective that integrates concepts, theories and insights from service management and marketing, information systems and platform economics.\r\n\r\nFindings\r\nThe paper outlines three platform types – smart data platform, smart product platform and matching platform – as strategic options for firms that wish to evolve from smart service providers to platform providers.\r\n\r\nResearch limitations/implications\r\nInvestigating smart service platforms calls for launching interdisciplinary research initiatives.

This device allows to measure electric and magnetic fields in small distances to the DUT (Device under Test) with high geometric precision and high sensitivity. Leading to a fast examination of EMC (Electromagnetic Compatibility) problems, because the electromagnetic properties are better understandable and therefore easier to solve than e.g. measurements in a far-field chamber. In addition, it is possible to extrapolate the near-fields into the far-field and to determine the radiation pattern of antennas and emitting objects. For this purpose, this paper deals with the basis of this transformation, the so-called surface equivalence theorem. This principle is then adapted to the measurement of near-field scanners and implemented accordingly.
