Grid Knowledge Management And Its Oilfield Research Organizations For Applied Research

Grid, also known as virtual computing environment, is an important network information technology in recent years. The advent of any new type of information technology will bring great influence and enlightenment to the research related to information management. Currently the huge advantages of the grid technology have already been shown.Thus this dissertation has as its basis the hotspot of the research and application of the grid technology--knowledge grid, focuses on the application of grid technoloty yin knowledge management, and elucidates the grid knowledge management technology, which is the combination of knowledge grid and knowledge management.According to the characteristics of knowledge grid and its application, this dissertation includes two essential parts: related technology of grid knowledge management and the application model of grid knowledge management.The technology related to grid knowledge management includes many aspects, but generally include: knowledge organization, knowledge discovery and knowledge supply(sharing) in grid knowledge management environment. Grid knowledge organization primarily through knowledge unit and knowledge structure using association and chain technoloty organized. Grid knowledge discovery is a parallel model of distributed knowledge discovery, mainly refers to the knowledge discovery services that intergrated in knowledge grid. Grid knowledge supply(sharing) mainly refers to the domain knowledge sharing that support for specific mission.In this dissertation, we describe the grid knowledge management from foiling four aspects: topology structure, resource space model, knowledge flow model and virtual organization. Topology structure logically presented the application model of grid knowledge management. Resource space model is a model for managing grid object with a universal resource view. Knowledge flow modeling is on the basis of combination of knowledge flow and work flow. It lets knowledge in grid flow more reasonable and smoothly. Virtual Organization is a teamwork form of organization in grid environment.Grid technology will bring the revolution of knowledge management.
