Abstract:The traditional resource integration optimization methods exist retrieval of single channel, long time consuming and passive response to business needs and other issues, can not meet the personalized needs of enterprises, therefore, under the background of big data, the integrated optimization method of enterprise information resources is studied. The method of information resource integration based on optimizing platform structure is emphasized. This method is mainly based on the theory of building socialism and resource dependence theory, follow the four elements of information resource creation, utilization, integration and effect evaluation, an optimization platform is built to improve the ability of information resource and independent integration, and to form a good environment for the effective utilization of information resource.From five aspects of function, retrieval, basic characteristics, resource organization and integration technology, this paper compares the traditional information resource integration mode with the optimized platform resource integration mode, and verifies the effect of the optimization platform resource integration.The experimental results show that the optimization method has the advantages of accurate and complete information resources integration, many retrieval channels, fast speed and so on. It greatly improves the speed of retrieval, and realizes the efficient integration of enterprise information resources.
