In order to study the problem that most of the existing Web-based distance education systems lack the monitoring of the learning process and the evaluation of students’ online learning behavior, a method of designing an online learning behavior evaluation system based on data mining is proposed, and an online learning behavior evaluation system is implemented. The system evaluates students’ online learning and gives formative evaluation results. The evaluation results are more accurate, and the recognition of teachers and students is more than 90%. The application of the system provides methods and means for objective, fair, and reasonable evaluation of students’ online learning and plays a guiding role for students in rationally arranging online learning; 99% of users said that the application of this system has a greater effect on promoting ordinary online learning help. The application of the system promotes students’ online learning to a certain extent, and the “learning behavior-effect” model constructed by the system has guiding significance for students to reasonably arrange online learning.

“…Moreover, [38] proposes a UML model for automatically generating user profiles with disabilities in XML format, enabling e-learning platforms to adapt their interfaces based on user accessibility needs. Lastly, [39] introduces Accessed, utilizing an MDD approach for developing accessible mobile applications for visually impaired individuals, employing a domain-specific language (DSL) within a model editor for defining models.…”

UML Profile to Model Accessible Web Pages

Creating accessible websites is essential to ensure the inclusion of users with disabilities, as defined in the Web Content Accessibility Guidelines (WCAG). In many countries, compliance with these guidelines is often legally mandated. Consequently, it is crucial to integrate accessibility considerations into Web development projects from the beginning. Unfortunately, accessibility requirements are often addressed only after the website is completed. To ensure compliance, it is proposed to incorporate accessibility requirements into system specifications and models. A Unified Modeling Language (UML) profile, called WebPageAcc, is introduced to streamline this process, allowing developers to incorporate accessibility requirements without extensive knowledge of accessibility standards. This profile provides stereotypes, data types, tagged values, and restrictions necessary to meet accessibility requirements. This study uses a four-stage method to create, apply, and validate the profile. Initially, an analysis of the WCAG 2.2 criteria is performed to define stereotypes, attributes and limitations aligned with the success criteria. Subsequently, the WebPageAcc profile is developed in Eclipse Papyrus, considering the identified elements. The third stage is to apply the profile to create a UML class diagram model of a real web page. Validation occurs in the final stage by executing Object Constraint Language (OCL) rules associated with attributes defined by the profile. Furthermore, an experiment is carried out to evaluate the usability difficulty of the profile among software developers. This multifaceted approach aims to improve the integration of accessibility into website development, ensuring inclusivity for a diverse user base while simplifying the implementation process for developers.

“…Schema.org: It is currently the most widely used vocabulary in the structured data community for Internet search engine optimization. To define accessibility metadata in Schema.org it is necessary to focus on the different types of web content that can be classified by metadata schema [12]. The "CreativeWork" category includes books, movies, photographs, videos, etc.…”

The increasing number of people are living with disability in the World and their access to formal education is considered a challenge for the development of the online education and educational resources. This problem is considered one of the 17 sustainable development goals that are focused on inclusive and equitable quality education. Nevertheless, the existing proposals for mainstream accessibility in virtual education are still complex to apply. However, the models, standards, and good practices to contribute to the virtual educational process and the design of learning for all are identified. For these reasons, in this paper, we describe an accessibility evaluation proposal based on 4 interaction domains: user analysis and interaction, intelligent systems, knowledge databases, and evaluation. In the same way, we describe a set of tools that constitute a Repository of Accessible Learning Objects (RALO) from the perspective of accessibility and adaptability metadata. In this line, the knowledge database follows the regulation and educational models focused on the students with disabilities needs and preferences from the conception of universal design. The validation of the proposal is based on the interaction study and analysis of regular and disabled students and teachers who developed the Learning Objects (LO). To determine whether there was consensus among the teacher's scores, we used Kendall's Coefficient of Concordance W.
