Research and analysis paper on digital library resource construction?

With the rapid development of network and information technology, people's demand for knowledge and information tends to be diversified and comprehensive, and it has become the trend of today's society to use the network for information exchange and service. As an important information institution in the whole society, how can the library meet the increasing information needs of users and provide complete and efficient services? With the popularity of electronic publications, more and more information producers have the opportunity to provide information services directly to users, which breaks the advantage of library's document service position and makes the library face severe challenges. The following is what I have carefully prepared for you: research and analysis of digital library resources construction, the content is for reference only, welcome to read!

The research and analysis of digital library resources construction are as follows:

Digital library is the development direction of library. This paper analyzes the resources of digital library in China, and puts forward some problems existing in the construction of digital library resources in China and their solutions.

Keywords: digital library resources

Today's world has entered the information age. While we are constantly changing and innovating this society, we are also enjoying the convenience and quickness brought by the digital society, and the digital library is one of them. The so-called digital library is a library that uses digital technology to process and store all kinds of illustrated documents, which is essentially a decentralized information system for multimedia production. In order to carry out the necessary construction of digital library resources, we need to take certain measures to make the information integration of digital library more orderly, so as to provide higher quality services.

First, the status quo of digital library resources construction

Compared with the traditional library, the digital library is not easy to be damaged, easy to save, small in information storage space, fast in long-distance transmission, convenient to enjoy information resources, convenient for information query and retrieval, and can save some precious national materials in digital form more conveniently and for a long time. However, digital libraries still face some problems.

1. Difficulties in storing information resources

The biggest problem faced by digital libraries is the difficulty in storing information resources. The information resources are increasing massively, but the technical ability to manage, backup and store these massive resources is limited. It is still necessary to improve the picture retrieval technology, human-computer interaction technology, multilingual retrieval, data exchange between different data standards and the software and tools needed by digital libraries, which all require the further development of science and technology.

2. Repeated construction of information resources

In the process of digital library construction, it is easy to cause repeated construction of information resources. Because paper resources and digital resources are relatively independent, they can't complement each other, and they can't check the data one by one, so digital libraries will buy a lot of digital resources in the construction process to expand the number of information resources. In this process, regardless of whether other libraries have been successfully built or not, we just blindly build digital resources, which will easily lead to a lot of waste of human and financial resources and repeated construction of information resources.

3. Information resources demand, * * * enjoy the predicament

Traditional library services are limited, while digital library services have broken the original restrictions and effectively extended the traditional library services. However, with the development of times and technology, information users require libraries to provide better information services such as personalization, diversity, continuity and effectiveness. In order to ensure the security of data resources in the server and the effective execution of the server, the digital library limits the maximum number of service responses and access terminals of the server to a certain extent, but it also causes the bottleneck of limited server access. Because there are many differences in data construction between different libraries, the data between libraries is not well connected, which seriously restricts the enjoyment of information resources and affects the service quality provided by libraries for information users.

Second, the advantages of digital library resources construction in the era of cloud computing

Cloud computing has powerful data storage function and network service function, which solves the technical heterogeneity problem of digital library, reduces the storage space cost of library and improves the human-computer interaction function. Cloud computing integrates, organizes, associates and navigates digital resources by combining distributed storage databases and one-stop search interfaces, thus realizing network expansion suite services and solving the problem of repeated construction of information resources. At the same time, cloud computing provides more diversified services and improves the information service efficiency of digital libraries. "Cloud" can expand the suite at any time, get it at any time, use it on demand and pay for it. Cloud computing has the characteristics of virtualization, large-scale, security, reliability, universality and extended suite.

Its wide application enables readers to enjoy the powerful computing power, humanized service and lower cost brought by library resources. Cloud computing can not only meet the needs of users, but also process and feed back the information they need in time to provide users with the needs of organizing and managing information resources. Users' data and computing power come from the Internet center, providing users with customized computing and storage services. Through the organization and matching of "cloud", the most professional and effective information resources and services are fed back to the user interface, so that Internet readers can enjoy reading conveniently, quickly and comprehensively. At the same time, we should continue to strengthen the research on cloud computing technology, make the technology develop continuously, study and develop the standardization, openness, confidentiality level, safety efficiency and enterprise integrity of cloud computing technology, and adhere to the sustainable development route, so as to form effective management of the library industry and provide legal protection for the safety and legitimate interests of library materials.

Third, the strategy of digital library resources construction in the era of cloud computing

In 2009, cloud computing technology was formally applied to library resource management with its powerful computing power and the advantages of massive data storage. Cloud computing technology also brought a brand-new and profound change to library management, service methods and service contents. Unified identity authentication, strictly control access rights, and formulate relevant standards, policies and regulations. They are the latest technical means that modern digital libraries can adopt to protect the legitimate rights and interests of libraries and data security.

1. Ensure the security of data storage and implement the latest technical means.

In order to ensure the storage safety of library materials, both libraries and service providers should adopt the most advanced, safest and most effective technical means to ensure the information safety of digital libraries to the maximum extent. For libraries, it is necessary to make timely and comprehensive backups of all kinds of collection materials, or to store them reliably and effectively for a long time. For service providers, advanced virtual mass storage technology can be used to manage and store data resources. This technology uses data copy to fault tolerance, and improves data availability and access efficiency by creating multiple copies for each virtual disk, without complex device restrictions. Moreover, due to the fault tolerance of mapping and verification technology, virtualized mass storage technology needs to maintain the same data in two different devices, even if the main device is damaged, it can be switched immediately and accessed through the mapping device.

2. Ensure service security and strictly control access rights.

In order to ensure the security of library services, access rights must be strictly checked. In the cloud environment, digital libraries can divide users into several levels from low to high. According to the different information needs of users, the access rights to resources are also strictly controlled. At present, digital libraries can adopt PMI authorization control technology with good effect. This technology is based on PKI system, which verifies users' rights when they request services, and provides all users with application-related authorized services, thus ensuring safe communication between users and service providers. PMI is authorized to manage digital libraries. After logging in to the cloud, ordinary users need to query data according to the roles assigned in advance, while users who play the role of administrators and undertake the maintenance of library data will be assigned corresponding operation rights after logging in to the system. Users need to call application services to complete the corresponding specific data maintenance work, and need to verify the relevant information that has been successfully sent to specific application services for inspection. To strictly control users' access to resources, we can also combine PMI authority control technology with single sign-on unified identity authentication. Digital library gives different access rights to resources according to different user levels, and the two match each other. At the same time, in order to effectively protect the security of data and services, cloud computing resources can be divided into multiple layers for control and management according to physical and logical aspects.

3. To achieve feasible and efficient access control, unified identity authentication is needed.

In order to ensure the security of library services, it is necessary to implement unified identity authentication. Unified identity authentication can maximize users' access efficiency, which is in line with the open characteristics of digital libraries. User authentication plays a very important role in data security in the cloud environment because only authorized users can access all resources of the cloud. In the cloud environment, digital libraries can use single sign-on unified identity authentication. Authorized users can enter and access "cloud" resources only once. Because of the cross-organizational, heterogeneous and dynamic characteristics of cloud computing environment, authentication is not required before using each cloud resource.

4. Meet data confidentiality requirements and improve information security facilities.

In order to meet the confidentiality requirements of library materials, it is necessary to improve the information security infrastructure to establish a secure network execution environment. Public key technology, digital authentication, certificate authority and security policy about public key all constitute public key infrastructure. As the core of information security infrastructure, public key infrastructure is the system and platform of public key encryption and digital signature service. In order to use encryption and digital signature technology more conveniently in the digital library under the cloud environment, only by establishing and perfecting PKI technology can the confidentiality, validity and integrity of data placed in the "cloud" be guaranteed, and the contents of digital information resources will not be peeped, denied or illegally tampered with by unauthorized persons during storage and transmission.

5. Ensure the security and legality of data and improve national laws, regulations and policies.

In order to ensure the information security and legitimate rights and interests of libraries, we should try our best to improve relevant national standards, regulations and policies. Library industry managers can organize standards and research related protocols for the application of cloud computing, because digital libraries should have their own relatively independent and perfect industry standards and norms for the application of cloud computing. Because some data security issues are related to national policies, the management policies, corporate reputation or national policies of cloud computing enterprises may have a certain impact on the security of cloud computing data. Therefore, in order to promote the promulgation and improvement of relevant management standards, laws and regulations, only through continuous consultation, running-in and research can every stakeholder in the whole industrial chain continue to develop and benefit, protect the intellectual property rights of digital information resources, and investigate relevant responsibilities.

The service mode and function of digital library have been greatly improved. In the process of digital library construction, only by fully considering the interests and relationships of libraries, cloud computing providers, users, third-party audit institutions and other parties, and rationally configuring various security attributes, can we ensure the security of this huge and complex system and build a reasonable and complete library cloud computing security framework. With the in-depth study of cloud computing technology, the digital library of cloud computing will continue to improve and develop better.

Four. conclusion

To sum up, with the development of digital technology and the arrival of the cloud era, digital libraries need to be further improved to adapt to the development of this era and continue to benefit us. Therefore, the relevant staff need to rationally allocate various security attributes of digital library and take measures to ensure the procedures of digital library resource construction, so as to continuously promote the construction and development of digital library. ?
