CHORUS Deliverable 2.1: State of the Art on Multimedia Search Engines

Based on the information provided by European projects and national initiatives related to multimedia search as well as domains experts that participated in the CHORUS Think-thanks and workshops, this document reports on the state of the art related to multimedia content search from, a technical, and socio-economic perspective. The technical perspective includes an up to date view on content based indexing and retrieval technologies, multimedia search in the context of mobile devices and peer-to-peer networks, and an overview of current evaluation and benchmark inititiatives to measure the performance of multimedia search engines. From a socio-economic perspective we inventorize the impact and legal consequences of these technical advances and point out future directions of research

Semantic discovery and reuse of business process patterns

Patterns currently play an important role in modern information systems (IS) development and their use has mainly been restricted to the design and implementation phases of the development lifecycle. Given the increasing significance of business modelling in IS development, patterns have the potential of providing a viable solution for promoting reusability of recurrent generalized models in the very early stages of development. As a statement of research-in-progress this paper focuses on business process patterns and proposes an initial methodological framework for the discovery and reuse of business process patterns within the IS development lifecycle. The framework borrows ideas from the domain engineering literature and proposes the use of semantics to drive both the discovery of patterns as well as their reuse

Combining SOA and BPM Technologies for Cross-System Process Automation

This paper summarizes the results of an industry case study that introduced a cross-system business process automation solution based on a combination of SOA and BPM standard technologies (i.e., BPMN, BPEL, WSDL). Besides discussing major weaknesses of the existing, custom-built, solution and comparing them against experiences with the developed prototype, the paper presents a course of action for transforming the current solution into the proposed solution. This includes a general approach, consisting of four distinct steps, as well as specific action items that are to be performed for every step. The discussion also covers language and tool support and challenges arising from the transformation

eXplainable AI for trustworthy healthcare applications

Acknowledging that AI will inevitably become a central element of clinical practice, this thesis investigates the role of eXplainable AI (XAI) techniques in developing trustworthy AI applications in healthcare. The first part of this thesis focuses on the societal, ethical, and legal aspects of the use of AI in healthcare. It first compares the different approaches to AI ethics worldwide and then focuses on the practical implications of the European ethical and legal guidelines for AI applications in healthcare. The second part of the thesis explores how XAI techniques can help meet three key requirements identified in the initial analysis: transparency, auditability, and human oversight. The technical transparency requirement is tackled by enabling explanatory techniques to deal with common healthcare data characteristics and tailor them to the medical field. In this regard, this thesis presents two novel XAI techniques that incrementally reach this goal by first focusing on multi-label predictive algorithms and then tackling sequential data and incorporating domainspecific knowledge in the explanation process. This thesis then analyzes the ability to leverage the developed XAI technique to audit a fictional commercial black-box clinical decision support system (DSS). Finally, the thesis studies AI explanation’s ability to effectively enable human oversight by studying the impact of explanations on the decision-making process of healthcare professionals

Portuguese physical literacy assessment (PPLA) : development and validation of an instrument for adolescents in physical education

The main purpose of this PhD thesis was to develop and validate a novel criterion-referenced Physical Literacy (PL) assessment system for application in Portuguese PE for grade 10-12 adolescents (15-18 years): the Portuguese Physical Literacy Assessment (PPLA). Inspired by the Australian Physical Literacy Framework (APLF), this tool is comprised of two instruments assessing the physical, cognitive, psychological, and social domains of PL: 1) PPLA-Questionnaire (PPLA-Q) and 2) the PPLA-Observation tool (PPLA-O). The first is a self-administered questionnaire with three modules, each respectively designed to assess the psychological, social, and part of the cognitive domains of PL; while the latter is an instrument with two modules that uses teacher-reported data to assess the physical and the remainder of the cognitive domain of PL. PPLA development and validation process is presented through five scientific papers: the first and fourth present the development of both instruments, marrying quantitative and qualitative methods; while the second, third and fourth establish evidence for the content and construct validity (dimensionality, measurement invariance across sex, and convergent and discriminant validity), as well as reliability (score and test-retest) at element-level, within each of the four domains assessed. Finally, the fifth articles focus on the integration of the full PPLA measurement model with all domains and elements, establishing its construct validity and reliability. Overall, the PPLA emerges as a highly feasible tool for the PE context that can be completed in around 20 minutes (students filling in the PPLA-Q) plus time spent by PE teachers in data insertion/copying into the PPLA-O spreadsheet. Its measurement model is best represented through an asymmetrical bifactor model, allowing for disentangling the variance associated with a general PL trait - referent to a transversal broadband meta-learning or disposition in movement settings – from variance of specific group factors (domains). PPLA can be used to provide a detailed and feasible assessment of each student’s PL journey, and to support pedagogical decisions (at local, regional, and national level) towards a more meaningful and targeted PE environment to promote PL learning. Further research is warranted in replicating these findings outside an imposition-laden COVID-19 setting, along with multiple fine-tuning to the PPLA. Similarly, adaptation of this tool to other age-ranges and its use as an aid in monitoring and advocating for PL inside a quality PE setting are open threads for future work.O principal objetivo desta tese de doutoramento foi desenvolver e validar um novo sistema de avaliação de Literacia Física (LF), baseado num referencial criterial, para aplicação em adolescentes portugueses do 10º ao 12º ano de escolaridade durante as aulas de EF: Portuguese Physical Literacy Assessment (PPLA). Inspirando-se no modelo australiano de LF (APLF), este sistema é composto por dois instrumentos que avaliam os domínios físico, cognitivo, psicológico e social da LF: 1) PPLA-Questionário (PPLA-Q) e 2) PPLA-Observação (PPLA-O). O primeiro é um questionário autoadministrado com três módulos, cada um concebido, respetivamente, para avaliar os domínios psicológico, social, e parte do domínio cognitivo da LF; já o último é um instrumento com dois módulos que utiliza dados reportados pelos professores de EF para avaliar o domínio físico e o resto do domínio cognitivo da LF. O seu processo de desenvolvimento e validação é apresentado através de cinco artigos científicos: o primeiro e quarto apresentam o desenvolvimento de ambos os instrumentos, através de métodos qualitativos e quantitativos; já o segundo, terceiro e quarto artigo estabelecem evidência para a validade de conteúdo e construto (dimensionalidade, invariância de medição em diferentes sexos, e validade convergente e discriminante) e fiabilidade (score e teste-reteste) do PPLA ao nível micro (elementos da LF). Finalmente, o quinto artigo foca-se na integração do modelo completo de medição do PPLA com todos os seus domínios e elementos, estabelecendo evidência da sua validade de construto e fiabilidade. Globalmente, o PPLA emerge como uma ferramenta altamente viável para aplicação em contexto de EF que pode ser completada em cerca de 20 minutos (preenchimento do PPLA-Q pelos alunos) acrescidos do tempo de inserção de dados, por parte do professor, na folha de cálculo do PPLA-O. O seu modelo de medição é melhor representado através de um modelo bifatorial assimétrico, que permite separar a variância associada a uma competência geral de LF - referente a uma meta- vi aprendizagem ou disposição transversal às diversas competências e contextos de movimento - da variância específica associada a cada domínio; permitindo também a análise independente do efeito ou relação de cada domínio com variáveis de interesse futuro. O PPLA pode ser utilizado para facultar uma avaliação detalhada e acessível do percurso efetuado por cada estudante na sua LF, e para apoiar decisões pedagógicas (a nível local, regional e nacional) com fim a tornar a EF um ambiente mais orientado para promover a aprendizagem deste conjunto de competências. De futuro, é necessária mais investigação no sentido de replicar os resultados obtidos nestes estudos, fora de um cenário fortemente limitado pela pandemia de COVID-19; e de efetuar múltiplas afinações ao PPLA. Do mesmo modo, são tópicos abertos para trabalho futuro a adaptação desta ferramenta a outras faixas etárias e a sua utilização como suporte na monitorização e disseminação da LF como um dos focos de desenvolvimento de EF de qualidade

31th International Conference on Information Modelling and Knowledge Bases

Information modelling is becoming more and more important topic for researchers, designers, and users of information systems.The amount and complexity of information itself, the number of abstractionlevels of information, and the size of databases and knowledge bases arecontinuously growing. Conceptual modelling is one of the sub-areas ofinformation modelling. The aim of this conference is to bring together experts from different areas of computer science and other disciplines, who have a common interest in understanding and solving problems on information modelling and knowledge bases, as well as applying the results of research to practice. We also aim to recognize and study new areas on modelling and knowledge bases to which more attention should be paid. Therefore philosophy and logic, cognitive science, knowledge management, linguistics and management science are relevant areas, too. In the conference, there will be three categories of presentations, i.e. full papers, short papers and position papers
