- AI-driven solutions for enhancing digital accessibility in higher educationPublication . Costa, José Paulo; Nacheva, Radka; Coelho, Ana Sofia; Martins, Oliva M.D.Digital accessibility is essential for ensuring that students with disabilities have equal access to educational materials in higher education. Despite the existence of standards like the Web Content Accessibility Guidelines (WCAG) and PDF Universal Access (PDF/UA), many institutions still face challenges in providing accessible digital content. Existing tools can identify accessibility issues but often fall short in automating the remediation process or offering personalized adjustments for individual learners. This paper presents an AI-driven framework designed to automate the detection, remediation, and personalization of digital content to meet accessibility requirements. The proposed framework integrates AI and machine learning to enhance the accessibility of PDFs, HTML content, and multimedia resources, ensuring compliance with WCAG 2.1 and PDF/UA standards. The study demonstrates that the AI system detects accessibility issues with 92% accuracy and successfully remediates 85% of identified issues. Additionally, the framework offers real-time personalized adjustments, improving user satisfaction for 94% of students with disabilities. The AI system also reduces the time and cost of ensuring accessibility, making it an efficient tool for educational institutions. The paper concludes with recommendations for further research to expand the framework’s capabilities and offers insights for developing inclusive education policies that leverage AI technology.
- Defining industrial tourism in the cross-border region of Portugal and SpainPublication . Scalabrini, Elaine C.B.; Alves, Francisco; Neto, Reginaldo; Teixeira, F.; García, Joaquin; Velasco, M.; Teixeira, João Paulo; Vaz, Roberto; Fernandes, Paula OdeteThis paper deals with the definition and valorisation of industrial and pre-industrial tourism in the cross-border region of Terras de Trás-os-Montes (Portugal) and Castilla y León (Spain). Industrial and pre-industrial heritage is crucial to collective memory and has significant cultural, historical and tourist value. Industrial tourism is emerging as an initiative that enhances historic landscapes and contributes to urban development, the revitalisation of communities and the preservation of heritage. It is considered an innovative strategy for rehabilitating territories, transforming old facilities into attractions, exploring historic sites or operating companies. The “IN_GENIOS_DUERO_DOURO” project focused on promoting this heritage in the Douro-Duero Euroregion. The methodology included detailed mapping and characterisation, creating a database with 1,079 sites identified in 22 Portuguese and 80 Spanish municipalities. The results show that most sites are in Spain (77.1 %). The municipalities with the most identified sites are Valladolid (250) in Spain and Mirandela (32) in Portugal. The main heritage categories include transport infrastructure (335), wineries (255) and the food industry (221). Around 47.27 per cent of the sites identified are accessible to tourists. The database created is fundamental for valuing, safeguarding and designing tourist routes.
- R&D in Portuguese companiesPublication . Praça, Lídia GalvãoThe purpose of this study is to charactetize and evaluate the Research and Development (R&D) activities of Portuguese companies, from 2016 to 2022. This is a descriptive statistical analysis of R&D activities, from an internal and external perspective of the companies and by sector of activity, based on the Community Innovation Survey. It was possible to observe an increase in R&D activities, especially intramural activities, as well as in activities carried out internally, on a continuous basis.
