The essence of contemporary cataloguing is the theory of bibliographic information, which embodies the essence of contemporary cataloguing。
Bibliographic information theory is based on bibliographic information, and substantive and core is the knowledge organization of information resources, i. E. The structuring of digital documentation information resources. To build a structured system of digital documentation information resources
The development of a contemporary bibliographical information paradigm that lays the foundation for an internet-based information bibliographical mechanism, sequences and exposes unsequenced digital documentation information resources as “a new task of contemporary cataloguing”。
Digital documentation information resources is a structured, holistic and logical system based on the accumulation of disordered and fragmented information in cyberspace, using certain rules and models and processing according to certain principles and methods. “consolidation” is the linking of the isomeral information resources; “reconstruction” is the regulation, organization of the various information resources assembled, and the aggregation, integration and reorganization of dispersed, relatively independent digital literature information into a new organic whole。
The integration of digital documentation information resources comprises three levels:
At the bottom, the data set is layered (grammatical-based integration), completing the integration of isomeric and distributed data sources at the syntax level.
The second level of knowledge integration (syntax-based integration) is the conceptual or semantic description and organization of digital resources in accordance with established knowledge organization systems and knowledge matrix structures, which is the integration of intrinsic linkages of knowledge and the formation of a knowledge grid capable of using digital resources efficiently.
The third level is the service integration layer (incorporation based on language), where application systems are dynamically constructed to provide intelligent knowledge services to users based on their individual needs。
The extraction of debris and the structuralization of debris “martography”, also known as the integration of knowledge, is the organization that uses the knowledge base to realize the concept and semantics of digital documentation resources, classifys, organizes, labels them according to a given knowledge system and links relatively independent digital documentation information through in-house technology。
Knowledge integration is an advanced stage of digital resource integration that not only optimizes the functionality of the local resources of the isomer system, but also generates a well-regulated knowledge network of digital literature resources in digital libraries. The modern digital documentation information organization uses bibliographical information as the basis for revealing the digital literature information landscape and building a digital documentation resource system for big data, with the possibility of intelligent and intelligent service providers。
Contemporary bibliographic information theory expands the subject from a purely text-based documentation information resource to a digital carrier's documentation information resource, web-based information resource sequencing and organization. Its rationale is to reduce the value of information entropy and improve the sequencing of information and to create a structured information source through the collection, processing, analysis and organization of web-based and even digital literature information. The unbis process of sequencing web-based documentation information is an insight into the intrinsic nature of contemporary bibliographic information activities。
The response to fragmentation information is based on orderly and structured digital documentation information, which is achieved through the control of digital bibliographic information。
There are four aspects to digital bibliographic information control
Bibliographic control is a tool for knowledge management, bibliographic control of bibliographic governance norms, processes and methods that focus on disorderly information; data mining is a prerequisite for content organization, with data mining emphasizing the links and integration of knowledge; intellectual processing is largely semantically linked; semantically creates a deeper insight into the overallity and relevance of knowledge in information resources; the visualization of the built-up body is a thematic map; and the system constructs a knowledge map (thematic map)。
Bibliographic information has an academic paradigm in which it systematically exposes the links between the content of information and integrates knowledge of disordered information; it specifies the characteristics of information, indicates the location of knowledge and establishes a normative view of isomer information at the semantic level. At the heart of the bibliographic information theory is the knowledge-structured relationship between the information content of the fragmentation and the logical linkage of the structure and content of the information resource as a whole, leading to the aggregation and re-engineering of the information resources of the big data concept to create intrinsic linkages. Bibliographic information theory continues to be the foundation for the structured programme of disorderly information, and the methodological basis for the reorganization of resource aggregation。
