Design And Implementation Of Enterprise-level Unified Information Search And Analysis Platform

In this paper,a unified information search and analysis platform for a communication group is constructed in order to improve the enterprise information system.The work efficiency of the enterprise is improved by means of analyzing how to query the massive digital information within the enterprise and locate what we need fast and accurately.After weighing the implementation efficiency,maturity rate and other indicators,some technologies have been selected to satisfy the enterprise which needs an enterprise-level search and analysis platform.Those technologies are further development of Solr in J2 EE framework,calculation framework for Big Data Analysis,language processing,intelligent algorithm,extensible system architecture of high availability and so on.Most of the maturity technical framework used in this program have extremely high success rate in enterprise implementation.In addition,based on continuous technical support of apache fund and a few well-known community,implementation is efficiency and easy to approach.Additionally,the collection of data which a search engine needed from the enterprise is introduced.Some core technologies of the search engine are also instroduced.The research on the architecture,code and configuration of Solr is carried out.Finally,a multi-library search engine based on SolrColud model is designed and implemented.In the process of management and maintenance,the author contributes to improving the convenience and scalability.The distributed control module in the system ensures the load balancing and high availability of the system,supports the establishment of distributed internal data index and implements the deployment as a cluster of the search server.According to the construction needs of enterprise,the unified information search and analysis platform for enterprises is flexibly expanded.Also,it reduces the same or similar business needs of the repeated investment and construction,shortens the construction period and investment costs.The unified information search and analysis platform is an infrastructure,which supports the unified information platform of enterprise group.In the follow-up process,the unified information search and analysis platform will be gradually extended to the whole enterprise country-wide,and support the information retrieval needs of the enterprise,including branch companies and their subordinate units.In this article a solution is provided to collect large amount of data from a variety of business data sources.The design and construction work for the personalized needs of the enterprise users is 80% done.In order to support the expanding scale of information construction in enterprise,an effictive personalized search solution is designed and practical verification is provided in this patper.
