Research Of Resource Search Application Based On Digital Campus

Search service is an important resource services digital campus,relying on the digital campus platform to realize the digital resources,library resources,campus-based set of resources such as multi-dimensional search,research direction is digital campus.For currently exist in the process of building the digital campus platform resource narrowly defined,the search function is weak shortcomings,propose a broad definition of digital resources on campus,and based on LUCENE open source search framework,combined with geographic information systems and positioning technology,to achieve campus smart Search to locate a variety of resources,and by example,demonstrate the effectiveness of the system.In this paper,the concept of digital campus resources were redefined to include not only the concept of the proposed types of electronic books,digital resources,but also self-study classrooms,dormitories,cafeteria,conference rooms and other infrastructure resources.On the digital campus resources are divided into three categories,namely,digital library resources,infrastructure,digital resources,equipment,digital resources,and unified coding logo,lay the foundation for a unified campus retrieval of digital resources.Through this way,users can not only find retrieval system of traditional literature digital resources,but also according to their own needs for campus facilities and hardware resources based on geographic positioning information.When the location information to locate the resource introduced geo-ft-idf algorithm mechanisms to improve the efficiency and quality of the resource search.Aiming at making digital campus resources without considering the user's identity when searching roles,search results cannot be given a better fit user needs shortcomings,presented to the campus network user's identity to be divided,and combined with the search for digital resources,constructed role-based personalized search resource model for clustering based on the traditional poor stability collaborative filtering personalized search model that exist for increasing the role model in the algorithm,the collaborative filtering added to different individuals role,thus overcoming the traditional collaborative filtering algorithms scalability issues and sparse problems and improve user satisfaction of digital resources search results.Constructed a prototype system based resource search digital campus.The system is digital campus resource definition proposed in this paper based on LUCENE open source search framework to transform the ordinary electronic literature class digital resources search and based on geographic information infrastructure and equipment resources to search the combination,while achieving a role-based personality resource search model,innovation and the digital campus resource search.Research and development of the system,so that the various types of digital campus users to roles based on their characteristics,to quickly find the information they need to effectively improve the level of information on campus.Meanwhile,in the theoretical research,improved resource search algorithm based on collaboration by adding role model improves the fit between search results and user expectations,with some theoretical research value.
