According to the idea of Model-Driven, a Portal UI Model supporting application services’ self-organization is presented in this paper.

This paper expounds the factors influencing the developing direction of the information network and the digital library,and probes into the requirements of the users in three aspects of the individualization,network self-service,and the mobility and its technologies.

The user s self-service has become the new start of current service mode of the library.

introduced the function and content of agricultural mechanization service organization, analyzed the reason of slow development for agricultural mechanization service organization, put forward considerations and measures.

Following with the constant development of agricultural machinery operation service organization, the level of agricultural mechanization production organization has been continually improved, the large-scale agricultural machine has been used, and the rural economy is booming.

The component element of the interactive information service organization is discussed.

By extending current service workflow net,adding collaborative organization service,resource service and role,and optimum combinatorial service quality as objective,the global and local execution station optimization algorithms were used to respectively obtain the optimum execution station for each local process.

Discipline group and self-organization of education knowledge in universities

First of all the author introduces the concepts of virtual organization, and then proposes a structure model of virtual organization, finally the self-organization and knowledge management of virtual organization are discussed.

The middleware supports mechanisms for cooperative data mining,self-organization,networking,and energy optimization to build higher-level service structures.
