Personalization and composition are two important features of modern service eco-sys-tems nowadays. A personalized requirements oriented virtual resource aggregation method is proposed in this paper. Service resources are formally described based on multi-dimensioned classification. Personalized requirements from applications are classified, reduced and finally expressed in formal and reusable manners. On this basis, a dynamic pruning based resource aggregation method is presented. The method pays attention to the features of both customer requirements and the organization of service resources. Multiple resources can be dynamically aggregated into coarse-grained virtual resources thus satisfy the requirements rapidly. Experiments show fairly good effectiveness and efficiency of the proposed method.%个性化与整合已成为现代服务生态系统的重要特征.对此提出一种面向个性化需求的虚拟服务资源整合方法.首先,服务资源被以多维度分类树的方式进行描述,而顾客的个性化需求经过分类、约简并以规范、可重用的方式得以表达.在此基础上,提出基于动态剪枝的服务资源整合方法.该方法兼顾了顾客需求和资源组织的特点,通过动态整合批量资源形成虚拟的大粒度资源从而快速满足个性化应用需求.实验表明利用该方法可能获得良好的效果和性能.
