Practical Experiences for the Development of Educational Systems in the Semantic Web

Abstract

<p class="AbstractHead">Semantic Web technologies have been applied in educational settings for different purposes in recent years, with the type of application being mainly defined by the way in which knowledge is represented and exploited. The basic technology for knowledge representation in Semantic Web settings is the ontology, which represents a common, shareable and reusable view of a particular application domain. Ontologies can support different activities in educational settings such as organizing course contents, classifying learning objects or assessing learning levels. Consequently, ontologies can become a very useful tool from a pedagogical perspective. This paper focuses on two different experiences where Semantic Web technologies are used in educational settings, the difference between them lying in how knowledge is obtained and represented. On the one hand, the OeLE platform uses ontologies as a support for assessment processes. Such ontologies have to be designed and implemented in semantic languages apt to be used by OeLE. On the other hand, the ENSEMBLE project pursues the development of semantic web applications by creating specific knowledge representations drawn from user needs. Our paper is consequently going to offer an in-depth analysis of the role played by ontologies, showing how they can be used in different ways drawing a comparison between model patterns and examining the ways in which they can complement each other as well as their practical implications</p

Optimization of self‐learning in Computer Engineering courses: An intelligent software system supported by Artificial Neural Network and Vortex Optimization Algorithm

“…Additionally, an adaptive, intelligent software system would enable both teachers and students to experience effective and efficient educational processes. It can be seen from the related literature that Artificial Intelligence is widely employed to develop such educational software tools or systems . So, the authors have focused on using Artificial Intelligence based techniques in order to develop a software system in the sense of the objectives of this study. Teaching abstract subjects may need more efforts or even more supportive materials in order to ensure necessary impact during learning processes.…”

Proposed Architecture Diagrams for Analyzing Semantic Web Search Engine for E-Learning Environments

“…E-learning environments can benefit from Semantic Web Technologies where the recent advances in technologies for web-based education provide learners variety of learning content available numerous resources may be used during Elearning , they also offers to learners the possibility of having a wealth of related content delivered to their desktop without explicitly identifying or requesting it and can utilize this rich content to enhance the learning experience, allowing them to deliver engaging and relevant courses. [7] The Semantic Web proposes that web contents are defined and linked not only for visualization but also to be used by The Semantic Web is a collection of standards, data structures, and software that make the online experience more detailed. First, language of HTML was developed in a way that people would understand the information rather than giving meaning to the information presented.…”

Semantic Formative E-Assessment for Project Management Professionals

“…[19] They can be used to evaluate students' authentic problem-solving abilities and their capacity to cope with real-world issues [20]. An example of successful e-assessment for openended questions in the field of accounting is the OeLE platform [15,30], which evaluates the students' answers based on the similarity from course ontology and answer ontology. A further development of the OeLE platform takes into consideration the procedural knowledge: the relative order between words matters while evaluating an answer [31].…”

“…Formative e-assessment implementations are possible due to various technologies: Web 2.0 [24,25,28], big data and distributed computing [34], mobile technologies [35], but also social and semantic technologies [15,30,36], which opened a new chapter, unfinished yet, for IT supported learning. The next section will present our solution for formative e-assessment of open-ended questions based on semantic technologies, specialized for project management training.…”
