Abstract: Based on the definition and analysis of KAAS,ascience and technology resource collaborative service model,called STRCS,was proposed in this paper.STRCS model includes technology resources model,service model and colla-borative model,and corresponding technology resources and service.At the same time,the service mapping mechanism between KAAS and STRCS was built to provide some new knowledge aggregation service pattern.Furthermore,aiming at the way of classification and aggregation of multiple tags querying and dynamic document indexing,an optimized mechanism was proposed.Meanwhile,knowledge synergy mechanism and personalized service of science and technology resources were given.A public service platform for science and technology resources based on socialization and know-ledge service was developed,and optimization of algorithm was used to enhance the ability and accuracy of personalized recommendation of science and technology resources platform,thus providing a new solution for the implementation and integration of collaborative innovation of science and technology resources and personalized knowledge service.

Key words: KAAS, Knowledge service cloud, Technology resource, Collaborative innovation service, STRCS
