The World 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 a dynamic(More)
This paper proposes a knowledge grid model for sharing and managing globally distributed knowledge resources. The model organizes knowledge in a three-dimensional knowledge space, and provides a knowledge grid operation language, KGOL. Internet users can use the KGOL to create their knowledge grids, to put knowledge to them, to edit knowledge, to partially(More)
To realize effective knowledge sharing in teamwork, this paper proposes a knowledge ¯ow model for peer-to-peer knowledge sharing and management in cooperative teams. The model consists of the concepts, rules and methods about the knowledge ¯ow, the knowledge ¯ow process model, and the knowledge ¯ow engine. A reference model for coordinating the knowledge(More)

Humans consciously and subconsciously establish various links, emerge semantic images and reason in mind, learn linking effect and rules, select linked individuals to interact, and form closed loops through links while co-experiencing in multiple spaces in lifetime. Machines are limited in these abilities although various graph-based models have been used(More)
A resource space model (RSM) is a model for specifying, sharing and managing versatile Web resources with a universal resource view. A normal resource space is a semantic coordinate system with independent coordinates and mutual-orthogonal axes. This paper first introduces the main viewpoint and basic content of the RSM, and then proposes a four-step method(More)
Organizations and communities are held together by knowledge flow networks whether people are aware of them or not. To plan such a network is to describe a formal and optimal flow of knowledge as the basis for effective teamwork. The difficulty is that the result of such planning depends greatly on the planners’ experience. This paper proposes a(More)
A semantic link peer-to-peer (P2P) network specifies and manages semantic relationships between peers’ data schemas and can be used as the semantic layer of a scalable Knowledge Grid. The proposed approach consists of an automatic semantic link discovery method, a tool for building and maintaining P2P semantic link networks (P2PSLNs), a semantic-based peer(More)
