This paper describe the case study of developing and providing the ontology-based educational information search service to overcome the limitations of the existing keyword-based search service. We used the OWL-DL 1) to build the core ontology DB from the existing metadata DB represented by the LOM, 2) to build the domain ontology DB of middle school Mathematics contents DB, 3) to merge the core ontology...
Designing ontologies that could be shared for developing ontology-based learning environments is still a challenge. The overall aim of the OURAL project was to provide a case study on common ontology design. It brought together researchers and practitioners from different domains (educational science, computer science, and cognitive psychology). We benefited from several on going field studies launched...
Today, networks can be seen as a large-scale knowledge base which contains a huge amount of resources. To be able to use them effectively, metadata should be associated with each sharable resource. As a result, authoring systems supporting metadata have been widely studied. In this paper, we attempt to develop an authoring system supporting metadata. From our previous research, it is found that "RELATION"...
The proposed web-based implementation of goal oriented knowledge acquisition and assessment environment allows to enhance learning process according to the requirements of student's knowledge level and his state of cognition. The use case actions definition is a starting point of the specification, which depends on different levels of learning scenarios and user cognition sub goals. The online assessment...
To support an automatic assistant learning and self- paced learning mechanism is the objective in today's e-learning environment. Researches of QA system focus on the following characteristics: understand questioners' questions in the form of nature language; enhance the accuracy of search result, and establish automatic learning mechanism. Base these characteristics, we develop a Semantic English...
The following topics are dealt with: computer supported cooperative work in design; collaborative design methods and tools; coordination methods; CSCW system security; grid computing; data and information management; networked manufacturing; workflow management; agents and multi-agent systems; ontology and knowledge management; Web services and semantic Web; e-commerce and e-businesses; virtual reality...
Most e-learning systems are non-intercommunicative and incomprehensive, which result in the isolation of the organizations and students that use e-learning systems. This paper describes a framework to probabilistically improve existing e-learning systems. MEKSI (Modern Educational Knowledge Service Infrastructure), which is a learner-centric, open educational architecture that supports conceptual...
Selecting appropriate learning services for a learner from the large number of heterogeneous knowledge sources is a complex and challenge task. This paper illustrates and discusses how semantic Web technologies such as RDF and ontology can be applied to e-learning system for helping learners select suitable learning course or retrieving relevant information. The paper presents the main features of...
The present research is devoted to development of a technology of the personalized search of learning objects in the Internet, which utilizes the learning object's and learner's ontologies, and aggregates the software agents for search of educational materials individually for each learner. The proposed technology manages the personalized search of learning objects for students to support their independent...
In this paper we introduce a tutoring approach for e-learning formative process. This approach is strictly related to the assessment phase. Assessment in the context of education is the process of characterizing what a student knows. The reasons to perform evaluation are quite varied, ranging from a need to informally understand student learning progress in a course to a need to characterize student...
It has been widely argued across e-learning research literature that the most innovative approaches to e-learning are those which allow learners to receive customized training material according to their needs and their own time and place. In this paper we propose an integrated approach which combines these constraints in generating a time-adjusted knowledge volume on-the-fly. Recent progress in semantic...
The teaching/learning of cognitive skills, such as problem-solving, is an important goal in most forms of education. In well-structured subject areas certain exercise problem types may be precisely described by means of machine-processable knowledge structures or ontologies. These ontologies can readily be used to generate individual problem examples for the student, where each problem consists of...
The Semantic Web is an extension of the current web in which information in a machine-processable form can coexist and complement the existing human-readable information, better enabling computers and people to work in co-operation. In this way, some processes that need to be carried out manually today will be performed automatically. E-learning is one of the domains that may benefit from this technology...
