resource vendors, such as Baidu, are developing rapidly in the resource construction in respect
to the academia, education and culture. These resource construction vendors are continuously
expanding their information resources and at the same time diversifying the forms of service.
It will cause great threat to the survival of digital libraries. The issues such as how the digital
library survives and develops, whether it will be replaced, etc, must be paid great attention to.
Therefore, the original concept about resources, organizational resources, technology, services and
functions of digital libraries should be changed, and the infrastructure of digital libraries should be
reconstructed. In this way the current challenges might be turned into opportunities for the rise of
digital libraries.
The article reviews several related research works and summarizes some important researches
and their main achievements in the big data era of digital libraries. Learning from the resource
vendors, we propose to use big data thinking to construct digital libraries in the era of big data. The
major points of this paper are described as follows:
In the aspect of the development of a digital library, we propose to extend the resources of
digital libraries by including not only the information in literature but also the information from
governments, network with broad social concerns; We also suggest expanding the scope of resource
integration in digital libraries, which aims at not only integrating resources within the library,
but also integrating the information resources from social point of view and from the network
platform, especially integrating the resource useful in solving complex problems; furthermore, to
improve the depth of process for digital library resource organization, it is necessary to pay more
attention to the deconstruction and reconstruction of knowledge during resource processing.
In the aspect of technology application for digital libraries, we propose to adopt technology
relative to semantic web application, and to build a framework able to link different types of
semantic relationships from heterogeneous resources, such as integrating the semantic relationship
implied in existing thesaurus and dictionaries into digital resource description, improving the
current clustering algorithms to make the data more fit for specific problems and able to detect the
patterns in the dataset. We discuss the widely used technologies for data analysis, because in the
future, the digital library will live on the resources and depend on these technologies to provide
high-quality data products. We emphasize the importance of grid search method about cross-
platform and cross-resources seamless search for future digital library, which can provide more
powerful semantic retrieval results to enhance the performance and quality of information retrieval.
In the aspect of digital library services, we emphasize the expansion of service products of the
digital library. Apart from providing the literature information and related information on the
internet, a digital library should be able to provide the think-tank products, such as the product of
recycled resources, the product of information analysis, and the video product of science, education
and culture resources. Moreover, the service mode of digital libraries should change from passive
and general services to active, automatic push and personalized service mode.
When considering the position of strategic development of digital library, we believe it is
