Gomez Ortega, A. (author), Noortman, Renee (author), Bourgeois, Jacky (author), Kortuem, G.W. (author)Most people are entangled with an ever-growing trail of data that results from their daily interactions with products and services. Yet, they are hardly aware of the nature and characteristics of the data within this trail. We design dataslip, a provocative artifact that materializes the personal data trail into a receipt and aims to elicit...conference paper 2024

van der Meer, M.T. (author), Jonker, C.M. (author), Vossen, Piek (author), Murukannaiah, P.K. (author)Presenting high-level arguments is a crucial task for fostering participation in online societal discussions. Current argument summarization approaches miss an important facet of this task-capturing diversity-which is important for accommodating multiple perspectives. We introduce three aspects of diversity: those of opinions, annotators, and...conference paper 2024

Liu, Q. (author), Ghodrat, Dr. Sepideh (author), Jansen, K.M.B. (author)We developed a shape-changing constructive kit, named Mimosa1. A key component of the toolkit is the modular hinges, each of which is equipped with two antagonistic shape memory alloy (SMA) wires. One wire deforms the hinge to approach its predetermined angle at high temperature, and another wire drives the hinge back when it cools down....conference paper 2024

Huisman, T. (author), van der Linden, J.G.M. (author), Demirović, E. (author)Survival analysis studies and predicts the time of death, or other singular unrepeated events, based on historical data, while the true time of death for some instances is unknown. Survival trees enable the discovery of complex nonlinear relations in a compact human comprehensible model, by recursively splitting the population and predicting...conference paper 2024

Valle Torre, M. (author), Oertel, Catharine (author), Specht, M.M. (author)Describing and analysing learner behaviour using sequential data and analysis is becoming more and more popular in Learning Analytics. Nevertheless, we found a variety of definitions of learning sequences, as well as choices regarding data aggregation and the methods implemented for analysis. Furthermore, sequences are used to study different...conference paper 2024

(author), Pera, M.S. (author)Web search has evolved into a platform people rely on for opinion formation on debated topics. Yet, pursuing this search intent can carry serious consequences for individuals and society and involves a high risk of biases. We argue that web search can and should empower users to form opinions responsibly and that the information retrieval...conference paper 2024

de Wit, S. (author), Hermans, F.F.J. (author), Specht, M.M. (author), Aivaloglou, E.A. (author)From an early age, girls may opt out of Computer Science (CS) for not fitting the CS stereotypes of being male, asocial and technology-oriented. These stereotypes might be strengthened by children's books on programming, but little is known about this. Therefore, this paper explores the gender, social interactions and interests of characters...conference paper 2024

Nadeem, A. (author)Although many Computer Science (CS) programs offer cybersecurity courses, they are typically optional and placed at the periphery of the program. We advocate to integrate cybersecurity as a crosscutting concept in CS curricula, which is also consistent with latest cybersecurity curricular guidelines, e.g., CSEC2017. We describe our experience...conference paper 2024

Cambaz, Doga (author), Zhang, X. (author)The recent emergence of LLM-based code generation models can potentially transform programming education. To pinpoint the current state of research on using LLM-based code generators to support the teaching and learning of programming, we conducted a systematic literature review of 21 papers published since 2018. The review focuses on (1) the...conference paper 2024

Goyal, Kshitij (author), Dumančić, S. (author), Blockeel, Hendrik (author)As machine learning models, specifically neural networks, are becoming increasingly popular, there are concerns regarding their trustworthiness, especially in safety-critical applications, e.g., actions of an autonomous vehicle must be safe. There are approaches that can train neural networks where such domain requirements are enforced as...conference paper 2024

Rudd, M.T. (author), Schultz, Marc R. (author), Bisagni, C. (author)Traditionally, launch vehicles are constructed with a series of buckling-prone thin-walled cylindrical and conical shells, in which the buckling behavior of these shells has been well studied and buckling design guidance exists. Conical-cylindrical shell geometry is now being utilized for launch-vehicle stage adapters and payload adapters due...conference paper 2024

Bouros, Panagiotis (author), Titkov, Artur (author), Christodoulou, G.C. (author), Rauch, Christian (author), Mamoulis, Nikos (author)A wide range of applications manage interval data. HINT was recently proposed to hierarchically index intervals in main memory. The index outperforms competitive structures by a wide margin, but under its current setup, HINT is able to service only single query requests. In practice however, real systems receive a large number of queries at...conference paper 2024
