摘　　要：随着因特网的蓬勃发展,网络计算正逐渐由“以计算机为中心”向“以人为中心”转变,按需计算成为发展趋势。然而用户需求的个性化以及互联网应用环境的千差万别,使得Web服务通过预先设定的程序很难理解和满足用户各种不同的需求,从而很难满足按需计算的两大要求———“适量”和“动态”。针对这个问题,该文在分析目前Web服务缺点的基础上,提出了在Web服务中将Agent技术的智能化特征,尤其是其迁移技术MobileAgent,与信息描述技术Ontology结合的解决方法,并给出了其应用框架,使得Web服务可以按照用户的需求提供个性化服务,初步实现按需计算的目标。With the development of Internet,the trend of Computing On Demand will be inevitable.However,with diversities of users' requirements and differences of application environments,it is hard for Web Services to exactly meet varies of demands from user only through prefabricated programs,thereby hard to achieve the two requirements of Computing On Demand:moderate and dynamic.In order to solve this problem,this paper analyses the shortcomings of Web Services,and then uses the combination of Mobile Agent,Ontology and so on.With the application architecture,Web Services may be autonomous,intelligent and semantic to provide individual services and reach the goal of Computing on Demand elementarily.
