A Knowledge Sharing and Collaboration System Model based on Internet

This paper proposes a knowledge sharing and collaboration system model (InKB) based on Internet. I t gives a way to collaborate and share knowledge between Web-based knowledge systems. InKB model has three layers. Data exchange layer, collaboration layer and knowledge-based application layer. Data exchange layer solves the problem of how to represent and manipulate knowledge. Collaboration layer devotes to collaboration between servers over Internet. Knowledge-based application layer defines the user interrace for knowledge processing over Internet, such as information searching, decisionsupport application and data mining. Data exchange between InKB Webs is in XML format, knowledge can be shared between heterogeneous knowledge bases, and knowledge can be remotely manipulated. Collaboration between InKBs is supported through collaboration agent, which can find resource user wants in lnKB system. As an open system model. InKB can also support I-ITTP request such as information retrieval and browse. Keyword: knowledge base, Internet. knowledge sharing,
