Communities and Emerging Semantics in Semantic Link Network: Discovery and Learning

Abstract: Abstract-TheWorld Wide Web provides plentiful contents for Web-based learning, but its hyperlink-based architecture connects Web resources for browsing freely rather than for effective learning. To support effective learning, an e-learning system should be able to discover and make use of the semantic communities and the emerging semantic relations in dynamic complex network of learning resources. Previous graph-based community discovery approaches are limited in ability to discover semantic communities. This … Show more

“…The service metadata model and related domain concepts are defined using ontology, which is expressed in a logic-based language so that detailed accurate, consistent, sound and meaningful distinctions can be made among the classes, properties, and relations. The service matching engine is built based on logic reasoning mechanisms, which can be achieved by ontology supporting tools, providing advanced functions to intelligent applications such as semantic search and retrieval [1]. As long as users describe their service requirements with terms from the same ontology model used to build the service descriptions, logical reasoning mechanisms can find the semantic similarity between the service descriptions and the user requirements, enabling the matching services to be discovered and returned to users.…”

“…The CPS-RSM can be used to normalize the classification trees. The integration of the CPS-SLN, CPS-RSM and other models can provide a stronger semantic model for organizing resources in the Cyber Physical Society [30,31].…”

“…Differently from our system, in order to query NAGA the user has to know all the relations that can possibly link two entities and has to learn a specific query language, other than know the exact name of the label she is looking for; while we do not require any technical knowledge to our users, just the ability to use tags. In [17] the author proposes Semantic Link Network (SLN ), a semantic data model to semantically link resources and derive implicit semantic links according to a set of relational reasoning rules. Inspired to this model, we adopt a different approach to elicit hidden knowledge and infer new meaningful links between resources in a RDF graph.…”
