Ontology Based Semantic Retrieval of Learner Profile
نویسنده
چکیده
E-learning refers to the use of electronic technologies to deliver and facilitate training anytime, anyplace. The major challenge in e-learning is that the learner is unable to extract relevant information on the web. Ontology-based semantic retrieval is a hotspot of current research. Ontologies play an important role in the development of knowledge. This paper proposes ontology based semantic retrieval for learner profile using Resource Description Framework (RDF). First, a data model is constructed to represent learner profile information on the Semantic Web. Then, semantic retrieval is obtained by applying the query language SPARQL (Simple Protocol and RDF Query Language). In addition SWRL (Semantic Web Rule Language) rule language is also applied to increase the expressiveness of OWL language. Experiments were performed using the editor Protégé 4.2 beta. The result shows the successful semantic retrieval of learner profile information on the Semantic Web.

Proposed Approach to Build Semantic Learner Model in Adaptive E-Learning
In the context of E-learning, adaptive systems are more specialized and focus on the adaptation of learning content and the presentation of this content. The adaptive E-learning system focuses on how the profile data is learned by the learner and pays attention to learning activities, cognitive structures and the context of the learning material. The system controls the process of collecting da...

Passenger information aims at improving the user-friendliness of public transport systems while influencing passenger route choices to satisfy transit user’s travel requirements. The integration of transit information from multiple agencies is a major challenge in implementation of multi-modal passenger information systems. The problem of information sharing is further compounded by the multi-l...
متن کاملDeveloping a BIM-based Spatial Ontology for Semantic Querying of 3D Property Information
With the growing dominance of complex and multi-level urban structures, current cadastral systems, which are often developed based on 2D representations, are not capable of providing unambiguous spatial information about urban properties. Therefore, the concept of 3D cadastre is proposed to support 3D digital representation of land and properties and facilitate the communication of legal owners...

In the learning environments, users would be helpless without the assistance of powerful searching and browsing tools to find their way. Web-based e-learning systems are normally used by a wide variety of learners with different skills, background, preferences, and learning styles. In this paper, we perform the personalized semantic search and recommendation of learning contents on the learning...
متن کاملSemiautomatic Image Retrieval Using the High Level Semantic Labels
Content-based image retrieval and text-based image retrieval are two fundamental approaches in the field of image retrieval. The challenges related to each of these approaches, guide the researchers to use combining approaches and semi-automatic retrieval using the user interaction in the retrieval cycle. Hence, in this paper, an image retrieval system is introduced that provided two kind of qu...
