Search And Recommendation Of University Institutional Repositories Mashup Map

The 21 st century is an era of rapid development of knowledge and science and technology.As the position of collecting,storing and disseminating the characteristic and high quality knowledge resources,the institutional repository plays an important role in knowledge sharing and dissemination.However,with the decentralized construction of the institutional repository,the problems of the limited scope of knowledge transmission,the difficulty for users to obtain resources,and the institutional repository of resources have been exposed.In the 21 st century,knowledge users are increasingly dependent on the internet for their knowledge resources,thus combining Mashup technology with the building of university institutional repository,building University Institutional Repositories Mashup Map(UIRMM),using UIRMM as a platform to optimize website search and recommendation functions,to facilitate users to access knowledge resources,and to enhance the academic impact of colleges and universities themselves.The purpose of this paper is to integrate Mashup technology into the construction of university institutional repository by building a institutional repository platform to improve the efficiency of knowledge resource utilization in institutional repository,improve the search and recommendation function of the website to enhance the user's experience of acquiring knowledge resources.The frame of the paper is as follows: the first chapter briefly reviews the research background and present research situation at home and abroad,and puts forward the research goal of this paper,which provides the theoretical and technical basis for the follow-up research;The second chapter analyzes the elements of UIRMM based on the definition and characteristics of university institutional repository and Mashup Technology,and the third chapter determines the selection scope of UIRMM university institutional repository materials,the fourth chapter explains the realization of the search function of UIRMM web site from two aspects: the realization steps of the search function of UIRMM web site and the technical methods of some applications.In the fifth chapter,under the guidance of the expected goal of the recommendation function of UIRMM website,through comparing different technical routes,analyze the advantages and disadvantages of different recommendation algorithms,and give the solution to improve the recommendation function.Finally,the future construction of institutional repository is prospected.There is a long way to go for the construction of the Institutional Repository,and the future development space is vast.I hope this paper can provide some ideas for the construction and development of the institutional repository in the future.
