Digital Library Information Service Based On Large Data

With cloud computing, the development of networking, social networking and other emerging technologies, data showing explosive growth, the emergence of massive data indicates the arrival of the era of big data. Digital information is widely present in the people around, how to get more information from the mass, better, more accurate, more timely, more useful information is increasingly becoming an issue of concern, and as an important channel for people to obtain information on the Libraries are supposed to be provided to the user information users need. However, now how to obtain useful information from massive data, then the useful feedback to the user, has become the trend of the development of library and information services. Analyze large data together with digital libraries become an inevitable trend, the big data technology into the digital library information service to provide users with a more detailed, more personalized information services.Based on previous research on the impact of big data for digital library information services for analysis. Discussion on Digital Library Information Service targets big data, content and methods from a more comprehensive perspective, hoping to play a valuable role in the big data environment of digital research library information service for digital libraries in big data environments.The article is divided into four parts.The first part introduces the theory of big data and digital libraries, the concept and characteristics of big data and digital libraries to describe, compare find a meeting point between them, from the development of digital libraries will proceed to describe big data and the feasibility of combining digital library.The second part describes the digital library information services, including digital library information service concepts, features, service model, some deficiencies and future trends of digital library information service induction appears to be the introduction of large digital data services library Information service.The third part describes the basic content based on digital library information services, in the era of big data how digital library information services. Based digital library resources including large data discovery, resource storage, resource organization, resource retrieval and its specific content analysis.Part IV discusses the types based on the contents of large data environment of digital library information service model based on digital libraries of large data service, describing the characteristics of a large digital library data services, and services to achieve the goal.
