  • Road safety using time-series classification algorithms
    Maximiliano Martins de Faria, Geraldo Bonorino Xexéo
    International Journal of Crashworthiness, 2026
    The article explores the use of time-series classification algorithms to improve driving safety by predicting potential accidents in the Crash Prediction System (CPS). The study results show that an efficient CPS with solid accuracy (73.87%) and low computational cost is possible with the traditional classifier RandomForest, recognised as a benchmark. This traditional classifier achieved good accuracy (73.87%) and low computational cost. However, specific classifiers showed superior efficiency (above 90%), despite having high computational costs, which in some cases may be impractical. Our study also found that the accelerometer sensor was effective across all seven datasets tested. The results with this sensor showed average accuracies above 80% and demonstrated a reduction in computational costs. The specific algorithms Rise, TimeSeriesForest, Rocket and Arsenal had promising results with average accuracy ranging from 75.38% to 80.05%. Rocket and Arsenal proved to be more stable and to have better results on average.
  • Toward an Ontology of Wargame Design
    Leandro Ouriques, Carlos Eduardo Barbosa, Joshua Kritz, Geraldo Xexéo
    IEEE Access, 2025
    Governments rely on military power to address conflicts, manage crises, and adapt to the evolving nature of modern warfare, which is often characterized by uncertainty and disorder. Wargames, traditionally military tools for simulating conflicts and decision-making, have gained prominence in civilian applications, including business, cybersecurity, disaster management, and critical infrastructure protection. Despite their utility, designing wargames is a time-intensive process with significant challenges, such as scenario creation and decision modeling, necessitating structured and systematic approaches. This research formalizes wargame design through ontology-driven conceptual modeling, structuring its key concepts, characteristics, and elements. Ontologies provide a structured representation of knowledge, facilitating communication, knowledge management, and collaborative design. As a result, we developed core ontologies for wargame design based on the Unified Foundational Ontology (UFO) and implemented them using OntoUML. Our innovation lies in analyzing wargame design processes across various countries and military organizations to develop a comprehensive reference model for wargame design. Additionally, we are the first to apply UFO for conceptual modeling of the wargame domain. These ontologies enhance wargame design by fostering standardization, adaptability, and support for intelligent systems, enabling dynamic and responsive scenarios. These contributions enhance wargame design efficiency and effectiveness, applicable to military and civilian contexts.

  • Towards a Knowledge Management Framework for LLM-Generated Personas in Collaborative Systems
    Lucas Nóbrega, Luiz Felipe Martinez, Yuri Lima, Carlos Eduardo Barbosa, Matheus Argôlo, Herbert Salazar, Geraldo Xexéo, Jano Moreira De Souza
    Proceedings of the International Conference on Computer Supported Cooperative Work in Design Cscwd, 2025
    With the advancement of Artificial Intelligence (AI) technologies, the world has been increasingly reshaped across multiple domains - healthcare, finance, education, and creative fields. This expansion transforms individual tasks and facilitates complex collaborations where humans and machines work to- gether in unprecedented ways. Through machine learning and, more specifically, large language models (LLMs), AI now plays a crucial role in enhancing productivity. Recent technological advancements have significantly boosted the text generation capabilities of LLMs, enabling them to simulate personas that can represent groups or specific well-known individuals. By simulating expert perspectives, LLMs provide insights to guide human decision-making across various collaborative frameworks in Computer-Supported Cooperative Work (CSCW). Personas, as simulated identities, have proven helpful in group brainstorming sessions, consensus-building exercises, and virtual advisory boards, which help represent diverse viewpoints and facilitate group decisions. Among these CSCW methods, the Delphi method is a well-established approach for reaching consensus among experts through iterative feedback and structured discussions. This work introduces a framework to manage and evaluate LLM-generated personas simulating expert input in Delphi studies. Our contributions include a framework designed for evaluating LLM personas in Delphi studies using a text similarity validation technique comparing real and simulated expert opinions and an evaluation of a Delphi about Brazilian higher education, assessing the LLMs' reliability in real-world scenarios. Findings show LLMs can effectively replicate expert perspectives, enhancing AI integration in specialized decision-making.

    Proceedings of the International Conference on Computer Supported Cooperative Work in Design Cscwd, 2025
    Software systems are critical resources for our daily lives. Due to that, computer science students need to learn software engineering knowledge and skills to develop software systems with the expected quality, under budget, and on schedule. The size and complexity of software systems and the short time to market make it necessary to have various software developers working as a team. In this scenario, the success of a project depends on coordination, communication, and collaboration. The evolution of network, communication, and computer technologies made it possible for people from different countries to work on the same project. Therefore, software engineers must collaborate remotely with others in Global Software Engineering (GSE) projects. Hence, students must also learn how to collaborate with people from different countries, with specific expectations, and different cultures and languages. This study lists the main GSE challenges the students must be ready to deal with, how researchers have addressed GSE, and how GSE education has been approached in the last five years. Researchers focused on teaching approaches, what students experienced during GSE courses, and the importance of GSE in industry. Students had the opportunity to face unsolved GSE challenges, and GSE courses still need to be improved.

  • Digital Collaboration in the Game 'Present of the Future': An Evaluative Study
    Daniel Martins, Marcos Antonio De Almeida, Lucas Nóbrega, Luiz Felipe Martinez, Carlos Eduardo Barbosa, Matheus Argôlo, Herbert Salazar, Jano Moreira De Souza, Geraldo Xexéo
    Proceedings of the International Conference on Computer Supported Cooperative Work in Design Cscwd, 2025
    The learning game “Present of the Future” has shown great potential as an effective tool for promoting futures literacy and speculative design in various educational and professional contexts. Through interactive and collaborative scenarios, participants are encouraged to explore future possibilities and develop creative solutions to contemporary challenges. Despite its promising impact, the game still lacks a structured and systematic process for evaluating the user experience on three levels: the immediate reaction to the game experience, the retention of learning in the short and long term, and collaboration in creating future artifacts. We propose a detailed experiment and an evaluative questionnaire composed of open and closed questions to fill this gap and provide a foundation for critically analyzing these dimensions. Although the experiment has not yet been conducted, the research establishes a robust theoretical and methodological framework that will allow, in future stages, the collection and analysis of quantitative and qualitative data to complement and enrich this study. Thus, we expect that the future application of these practices will contribute to a deeper understanding of the pedagogical and collaborative effects of the game.
  • Comparative Analysis of Single and Multiagent Large Language Model Architectures for Domain-Specific Tasks in Well Construction
    V. B. Sabbagh, C. B. C. Lima, G. Xexéo
    SPE Journal, 2024
    Summary This paper explores the application of large language models (LLMs) in the oil and gas (O&G) sector, specifically within well construction and maintenance tasks. The study evaluates the performances of a single agent and a multiagent LLM-based architecture in processing different tasks, offering a comparative perspective on their accuracy and the cost implications of their implementation. The results indicate that multiagent systems offer improved performance in question and answer (Q&A) tasks, with a truthfulness measure 28% higher than single-agent systems but at a higher financial cost. Specifically, the multiagent architecture incurs costs that are, on average, 3.7 times higher than those of the single-agent setup due to the increased number of tokens processed. Conversely, single-agent systems excel in Text-to-SQL (structured query language) tasks, particularly when using the Generative Pre-Trained Transformer 4 (GPT-4), achieving a 15% higher score compared to multiagent configurations, suggesting that simpler architectures can sometimes outpace complexity. The novelty of this work lies in its original examination of the specific challenges presented by the complex, technical, unstructured data inherent in well construction operations, contributing to strategic planning for adopting generative artificial intelligence (AI) (Gen-AI) applications and providing a basis for optimizing solutions against economic and technological parameters.
